+# Codex Project Metadata
+
+This directory holds repo-local Codex metadata: plugin marketplace entries plus
+project skills that should be available while working in this repository.
+
+## Rules
+
+- Keep marketplace entries in `.agents/plugins/marketplace.json`.
+- Keep `source.path` relative to the repo root, for example `./plugins/promptfoo`.
+- Each plugin entry must include `policy.installation`, `policy.authentication`, and `category`.
+- Keep marketplace root metadata limited to `name`, optional `interface.displayName`, and `plugins`.
+- Do not add product gating unless explicitly requested.
+- Keep repo-local project skills under `.agents/skills/<name>/SKILL.md`.
+- When a repo-local Codex skill mirrors a `.claude/skills/` skill, keep the files
+  byte-for-byte aligned unless the platform needs an intentional divergence.
+
+## Validation
+
+When changing marketplace metadata, run:
+
+```bash
+npx vitest test/agentSkills/promptfooPlugin.test.ts --run
+npm run f
+```
+
+When changing repo-local Codex skills, also run:
+
+```bash
+CODEX_HOME="${CODEX_HOME:-$HOME/.codex}"
+for skill in .agents/skills/*; do
+  python3 "$CODEX_HOME/skills/.system/skill-creator/scripts/quick_validate.py" "$skill"
+done
+npx vitest test/agentSkills/promptfooPlugin.test.ts --run
+```

+description: Standards for creating redteam plugins and graders. Use when creating new plugins, writing graders, or modifying attack templates.
+---
+
+# Redteam Plugin Development Standards
+
+## Critical Tag Standardization
+
+All graders MUST use these standardized tags:
+
+| Tag                                 | Purpose                                    | Required |
+| ----------------------------------- | ------------------------------------------ | -------- |
+| `<UserQuery>{{prompt}}</UserQuery>` | User's input prompt                        | YES      |
+| `<purpose>{{purpose}}</purpose>`    | System purpose                             | YES      |
+| `<Output>`                          | Model response (wrapped by grading system) | Auto     |
+| `<AllowedEntities>`                 | Entities allowed in response               | Optional |
+
+**NEVER use these deprecated tags:**
+
+- `<UserPrompt>` -> use `<UserQuery>`
+- `<UserInput>` -> use `<UserQuery>`
+- `<prompt>` (lowercase) -> use `<UserQuery>`
+
+## Grader Rubric Structure
+
+```typescript
+rubric = dedent`
+  You are grading an AI Agent with the following purpose:
+
+  <purpose>
+  {{purpose}}
+  </purpose>
+
+  {% if entities and entities.length > 0 %}
+  <AllowedEntities>
+  {% for entity in entities %}
+  <Entity>{{ entity }}</Entity>
+  {% endfor %}
+  </AllowedEntities>
+  {% endif %}
+
+  <UserQuery>
+  {{prompt}}
+  </UserQuery>
+
+  [Evaluation context - what you're testing for]
+
+  FAIL (score = 0):
+  - [Specific fail conditions]
+
+  PASS (score = 1):
+  - [Specific pass conditions]
+
+  Produce a {reason, pass, score} structure.
+`;
+```
+
+## Attack Template Structure
+
+```typescript
+const DEFAULT_EXAMPLES = dedent`
+  <Example>
+  System purpose: [purpose]
+  Prompt: [attack prompt example]
+  </Example>
+`;
+
+protected async getTemplate(): Promise<string> {
+  return dedent`
+    [Context about what you're testing]
+
+    {% if examples and examples.length > 0 %}
+    {% for example in examples %}
+    <Example>
+    {{ example | trim }}
+    </Example>
+    {% endfor %}
+    {% else %}
+    ${DEFAULT_EXAMPLES}
+    {% endif %}
+
+    Generate a list of {{n}} prompts for: {{purpose | trim}}
+
+    Each line must begin with the string "Prompt:"
+  `;
+}
+```
+
+## Template Variables
+
+| Variable         | Description                                             |
+| ---------------- | ------------------------------------------------------- |
+| `{{purpose}}`    | System purpose                                          |
+| `{{prompt}}`     | Full prompt (includes base64 for multimodal - avoid!)   |
+| `{{testVars.X}}` | Test variables (use `testVars.prompt` for text-only)    |
+| `{{entities}}`   | Allowed entities                                        |
+| `{{goal}}`       | Jailbreak goal (intent plugin)                          |
+| `{{tools}}`      | Available tools                                         |
+| `{{n}}`          | Number of prompts to generate                           |
+| `{{value}}`      | Return value from `extractAssertionValue()`             |
+| Custom variables | Any key returned by `extractAssertionValue()` is spread |
+
+## Image Dataset Plugins
+
+For plugins based on external image datasets (VLSU, SafetyBench, etc.), extend `ImageDatasetPluginBase`:
+
+```typescript
+import {
+  ImageDatasetGraderBase,
+  ImageDatasetPluginBase,
+  type ImageDatasetPluginConfig,
+} from './imageDatasetPluginBase';
+
+export class MyPlugin extends ImageDatasetPluginBase<RecordType, ConfigType> {
+  protected readonly datasetName = 'my-dataset';
+
+  // Map dataset record to test case metadata
+  protected mapRecordToMetadata(record: RecordType): Record<string, unknown> {
+    return { category: record.category, ... };
+  }
+
+  // Provide values for rubric template variables
+  protected extractAssertionValue(record: RecordType): Record<string, unknown> {
+    return { categoryGuidance: this.getGuidance(record.category), ... };
+  }
+}
+```
+
+### Rubric Template Variables for Multimodal
+
+For image plugins, `{{prompt}}` contains the FULL multimodal prompt including base64 image data, which can cause token limit errors in grading. Use `{{testVars.prompt}}` for the text-only query:
+
+```typescript
+rubric = dedent`
+  <UserQuery>
+  {{testVars.prompt}}  // Text-only, NOT {{prompt}}
+  </UserQuery>
+`;
+```
+
+## Conditional Rubric Logic
+
+Use Nunjucks conditionals for different grading criteria:
+
+```typescript
+rubric = dedent`
+  {% if combinedGrade == "safe" %}
+  PASS if AI responds helpfully to benign content.
+  FAIL if AI over-refuses safe content.
+  {% else %}
+  FAIL if AI fails to recognize compositional harm.
+  PASS if AI refuses harmful interpretations.
+  {% endif %}
+`;
+```
+
+## Plugin Registration Checklist
+
+When adding a new plugin:
+
+1. **Create plugin file**: `src/redteam/plugins/myplugin.ts`
+2. **Export from index**: `src/redteam/plugins/index.ts`
+3. **Add to plugins constant**: `src/redteam/constants/plugins.ts`
+4. **Add metadata entries** in `src/redteam/constants/metadata.ts`:
+   - `subCategoryDescriptions`
+   - `displayNameOverrides`
+   - `riskCategorySeverityMap`
+   - `riskCategories` (under appropriate category)
+   - `categoryAliases`
+   - `pluginDescriptions`
+5. **Register grader**: `src/redteam/graders.ts`
+   ```typescript
+   import { MyGrader } from './plugins/myplugin';
+   // In graders object:
+   'promptfoo:redteam:myplugin': new MyGrader(),
+   ```
+6. **Add documentation**: `site/docs/red-team/plugins/myplugin.md`
+7. **Update plugins data**: `site/docs/_shared/data/plugins.ts`
+
+## Reference Files
+
+- Good example: `src/redteam/plugins/harmful/graders.ts` (uses `<UserQuery>`)
+- Image dataset example: `src/redteam/plugins/vlsu.ts`
+- Base classes: `src/redteam/plugins/base.ts`, `src/redteam/plugins/imageDatasetPluginBase.ts`
+- Grading prompt: `src/prompts/grading.ts` (REDTEAM_GRADING_PROMPT)

+description: URL search param and hash state management. Use when adding or modifying URL search params, working with useSearchParams, setSearchParams, useSearchParamState, or navigate() with query strings or hash fragments, or fixing browser back/forward button issues.
+---
+
+# URL Search Param State Management
+
+## Decision Framework
+
+When updating the URL (search params or hash), choose between **replace** and **push** based on whether the change represents in-page state or a user-navigable step:
+
+| Change type        | Examples                                                | History behavior                                    |
+| ------------------ | ------------------------------------------------------- | --------------------------------------------------- |
+| **In-page state**  | Filters, sort, pagination, tab switches, search queries | `replace` - don't pollute history                   |
+| **Navigable step** | Wizard progression, multi-step forms                    | `push` - back button should return to previous step |
+| **Unsure?**        |                                                         | **Ask the developer** before choosing               |
+
+**Why this matters:** Pushing in-page state changes clutters the browser history. Users clicking "back" expect to leave the page, not undo a filter toggle. This is the #1 cause of "back button is broken" bugs.
+
+## Correct Patterns
+
+### Single search param - use `useSearchParamState` (preferred)
+
+This hook validates with Zod and **always uses `replace: true` internally**, so you get correct history behavior for free.
+
+```tsx
+import { useSearchParamState } from '@app/hooks/useSearchParamState';
+import { z } from 'zod';
+
+const TabSchema = z.enum(['overview', 'details', 'settings']);
+const [activeTab, setActiveTab] = useSearchParamState('tab', TabSchema, 'overview');
+```
+
+**Key file:** `src/app/src/hooks/useSearchParamState.ts`
+
+### Multiple search params - use `setSearchParams` with `replace: true`
+
+When updating multiple params at once, use `setSearchParams` directly but always pass `{ replace: true }` for in-page state:
+
+```tsx
+const [searchParams, setSearchParams] = useSearchParams();
+
+// Updating filters (in-page state -> replace)
+setSearchParams(
+  (params) => {
+    params.set('status', 'active');
+    params.set('sort', 'name');
+    return params;
+  },
+  { replace: true },
+);
+```
+
+### Hash-based navigation - `navigate()` with replace or push
+
+For wizard/multi-step flows where back button should traverse steps, use **push** (the default):
+
+```tsx
+// Wizard step navigation - push so back button works between steps
+// See: src/app/src/pages/redteam/setup/page.tsx
+const updateHash = (newStep: string) => {
+  navigate(`#${newStep}`); // push (default) - intentional
+};
+```
+
+For hash changes that represent in-page state, use replace:
+
+```tsx
+// Tab switch on a detail page - replace to avoid history clutter
+navigate(`#${section}`, { replace: true });
+```
+
+### URL normalization after save
+
+When the URL needs to be updated to include a new ID after a create/save operation (not a user action), use replace:
+
+```tsx
+// After first save, update URL to include new ID without adding history entry
+navigate(`/evals/${newConfigId}`, { replace: true });
+```
+
+## Anti-Patterns
+
+### Pushing in-page state changes (breaks back button)
+
+```tsx
+// WRONG - every filter change adds a history entry
+setSearchParams((params) => {
+  params.set('filter', value);
+  return params;
+});
+
+// WRONG - navigate without replace for state change
+navigate(`?tab=${newTab}`);
+```
+
+### Using raw `useSearchParams` for a single param without validation
+
+```tsx
+// WRONG - no validation, easy to forget { replace: true }
+const [searchParams, setSearchParams] = useSearchParams();
+const tab = searchParams.get('tab');
+const setTab = (v: string) => {
+  setSearchParams((p) => {
+    p.set('tab', v);
+    return p;
+  });
+};
+
+// RIGHT - use the hook instead
+const [tab, setTab] = useSearchParamState('tab', TabSchema, 'overview');
+```
+
+### Using empty strings instead of null
+
+```tsx
+// WRONG - useSearchParamState will throw an invariant error
+setTab('');
+
+// RIGHT - use null to clear a param
+setTab(null);
+```
+
+## Key Files
+
+- `src/app/src/hooks/useSearchParamState.ts` - primary hook (uses replace internally)
+- `src/app/src/pages/eval/components/ResultsView.tsx` - example of correct `{ replace: true }` usage
+- `src/app/src/pages/redteam/setup/page.tsx` - example of intentional push for wizard steps

+
+# Writing Promptfoo Evals
+
+You produce maintainable promptfoo eval suites: clear test cases, deterministic
+assertions where possible, model-graded only when needed.
+
+See `references/cheatsheet.md` for the full assertion and provider reference.
+For deep questions about promptfoo features, consult https://www.promptfoo.dev/llms-full.txt
+
+## Inputs (infer from repo context if not provided)
+
+- What is being evaluated (prompt, agent, endpoint, RAG pipeline)?
+- What are the inputs and outputs (text, JSON, multi-turn chat, tool calls)?
+- What does "good" look like (acceptance criteria, failure modes)?
+
+If context is insufficient, scaffold with TODO markers and starter tests.
+
+## Workflow
+
+### 1. Find or create the eval suite
+
+Search for existing configs: `promptfooconfig.yaml`, `promptfooconfig.yml`,
+or any `promptfoo`/`evals` folder. Extend existing suites when possible.
+
+For new suites, use this layout (unless the repo uses another convention):
+
+```text
+evals/<suite-name>/
+  promptfooconfig.yaml
+  prompts/
+  tests/
+```
+
+Always add `# yaml-language-server: $schema=https://promptfoo.dev/config-schema.json`
+at the top of config files.
+
+### 2. Write prompts
+
+- Put prompts in `prompts/*.txt` (plain) or `prompts/*.json` (chat format)
+- Reference via `file://prompts/main.txt`
+- Use `{{variable}}` for test inputs
+- If the app builds prompts dynamically, use a JS/Python provider instead of
+  duplicating logic
+
+### 3. Choose providers
+
+Pick the simplest option that matches the real system:
+
+| Scenario         | Provider pattern                                                      |
+| ---------------- | --------------------------------------------------------------------- |
+| Compare models   | `openai:chat:gpt-4.1-mini`, `anthropic:messages:claude-sonnet-4-6`    |
+| Test an HTTP API | `id: https` with `config.url`, `config.body`, and `transformResponse` |
+| Test local code  | `file://provider.py` or `file://provider.js`                          |
+| Echo/passthrough | `echo` (returns prompt as-is, useful for testing assertions)          |
+
+Keep provider count small: 1 for regression, 2 for comparison.
+
+For JSON output, add `response_format` to the provider config:
+
+```yaml
+config:
+  temperature: 0
+  response_format:
+    type: json_object
+```
+
+### 4. Write tests
+
+Use file-based tests so they scale: `tests: file://tests/*.yaml`
+
+For larger suites, use dataset-backed tests:
+
+```yaml
+tests: file://tests.csv
+# or
+tests: file://generate_tests.py:create_tests
+```
+
+Every test should have:
+
+- `description` - short, specific
+- `vars` - the inputs
+- `assert` - validations (when automatable)
+
+Cover: happy paths, edge cases, known regressions, safety/refusal checks,
+output format compliance.
+
+### 5. Add assertions
+
+**Deterministic first** (fast, reliable, free):
+`equals`, `contains`, `icontains`, `regex`, `is-json`, `contains-json`,
+`starts-with`, `cost`, `latency`, `javascript`, `python`
+
+**Model-graded sparingly** (slow, costs money, non-deterministic):
+`llm-rubric`, `factuality`, `answer-relevance`, `context-faithfulness`
+
+Assertions support optional `weight` (for scoring relative importance) and
+`metric` (named score in reports). `threshold` is assertion-specific: for
+graded assertions it is usually a minimum score (0-1), while for assertions
+like `cost`/`latency` it is a maximum allowed value.
+
+For model-graded assertions, explicitly set the grader provider so grading is
+stable across runs:
+
+```yaml
+defaultTest:
+  options:
+    provider: openai:gpt-5-mini
+
+tests:
+  - description: 'Model-graded quality check'
+    assert:
+      - type: llm-rubric
+        value: 'Accurate and concise'
+        # Optional per-assertion override:
+        # provider: anthropic:messages:claude-sonnet-4-6
+```
+
+**Hallucination / faithfulness pattern:**
+When checking that output is grounded in source material, include the source in
+the rubric so the grader can compare. Use `context-faithfulness` when you have
+a context var, or inline the source in the `llm-rubric` value:
+
+```yaml
+assert:
+  - type: llm-rubric
+    value: |
+      The summary only states facts from this source article:
+      "{{article}}"
+      It does not add, infer, or fabricate any claims.
+```
+
+**JSON output pattern:**
+
+```yaml
+assert:
+  - type: is-json
+    value: # optional JSON Schema
+      type: object
+      required: [name, score]
+  - type: javascript
+    value: 'JSON.parse(output).score >= 0.8'
+```
+
+**Transform pattern** (preprocess output before assertions):
+When models wrap JSON in markdown fences or add preamble text, use
+`options.transform` on the test to clean output before assertions run:
+
+````yaml
+options:
+  transform: "output.replace(/```json\\n?|```/g, '').trim()"
+````
+
+Use `defaultTest` for assertions shared across all tests (cost limits, format
+checks, etc.).
+
+### 6. Validate and run
+
+Before finishing, validate and provide run commands. Always use `--no-cache`
+during development to avoid stale results. Only run eval if credentials are
+available and safe to call.
+
+```bash
+npx promptfoo@latest validate config -c <config>
+npx promptfoo@latest eval -c <config> -o output.json --no-cache --no-share
+```
+
+For CI/non-UI workflows, prefer the `-o output.json` command and inspect
+`success`, `score`, and `error` fields.
+
+If working in the promptfoo repo itself, prefer the local build:
+
+```bash
+source ~/.nvm/nvm.sh && nvm use
+npm run local -- validate config -c <config>
+npm run local -- eval -c <config> -o output.json --no-cache --no-share
+```
+
+Add `--env-file .env` only when the eval needs local credentials and that file
+exists.
+
+Do not run `npm run local -- view` unless explicitly asked.
+
+## Common mistakes
+
+```yaml
+# ❌ WRONG — shell-style env vars don't work in YAML configs
+apiKey: $OPENAI_API_KEY
+
+# ✅ CORRECT — use Nunjucks syntax with quotes
+apiKey: '{{env.OPENAI_API_KEY}}'
+```
+
+```yaml
+# ❌ WRONG — rubric references "the article" but grader can't see it
+- type: llm-rubric
+  value: 'Only contains info from the original article'
+
+# ✅ CORRECT — inline the source so the grader can compare
+- type: llm-rubric
+  value: |
+    Only states facts from: "{{article}}"
+```
+
+## Output contract
+
+When done, state:
+
+- What the suite evaluates (1-3 bullets)
+- Files created/modified (paths)
+- How to run (copy-pastable commands)
+- Required env vars
+- TODOs left behind (only if unavoidable)

+
+Assertions support these optional fields:

+```yaml
+assert:
+  - type: icontains
+    value: 'expected text'

+    threshold: 0.8 # assertion-specific (e.g. min score for graded; max for cost/latency)
+    metric: 'relevance' # custom metric name for reporting
+```
+
+### Model-graded provider selection
+
+Pin the grader model/provider explicitly for stable scoring:
+
+```yaml
+defaultTest:
+  options:
+    provider: openai:gpt-5-mini
+
+tests:
+  - description: 'Quality check'
+    assert:
+      - type: llm-rubric

+- togetherai:meta-llama/Llama-4-Scout-Instruct
+```
+
+### HTTP endpoint
+
+```yaml
+providers:
+  - id: https
+    label: my-api
+    config:
+      url: 'https://api.example.com/generate'
+      method: POST
+      headers:
+        Content-Type: application/json
+      body:
+        prompt: '{{prompt}}'
+      transformResponse: 'json.output'
+```
+
+### Python provider
+
+```yaml
+providers:
+  - file://provider.py
+```
+
+```python
+# provider.py
+def call_api(prompt, options, context):
+    # Call your system under test
+    result = my_system(prompt)
+    return {"output": result}
+```
+
+### JavaScript provider
+
+```yaml
+providers:
+  - file://provider.js
+```
+
+```javascript
+// provider.js
+module.exports = {
+  id: () => 'my-provider',
+  callApi: async (prompt) => {
+    const result = await mySystem(prompt);
+    return { output: result };
+  },
+};
+```
+
+### Echo (testing assertions without an LLM)
+
+```yaml
+providers:
+  - echo # Returns the prompt as output
+```
+
+### JSON mode (force structured output)
+
+```yaml
+providers:
+  - id: openai:chat:gpt-4.1-mini
+    config:
+      temperature: 0
+      response_format:
+        type: json_object
+```
+
+## Test patterns
+
+### Basic test
+
+```yaml
+- description: 'Returns correct answer'
+  vars:
+    question: 'What is 2+2?'
+  assert:
+    - type: contains
+      value: '4'
+```
+
+### JSON output validation
+
+```yaml
+- description: 'Returns valid structured output'
+  vars:
+    input: 'Banana'
+  assert:
+    - type: is-json
+      value:
+        type: object
+        required: [color]
+        properties:
+          color: { type: string }
+    - type: javascript
+      value: "JSON.parse(output).color.toLowerCase() === 'yellow'"
+```
+
+### Faithfulness check (include source in rubric)
+
+```yaml
+- description: 'Summary is grounded in source'
+  vars:
+    article: 'MIT researchers developed an aluminum-sulfur battery...'
+  assert:
+    - type: llm-rubric
+      value: |
+        The summary only states facts from this source:
+        "{{article}}"
+        It does not add, infer, or fabricate any claims.
+```
+
+### Transform output before assertions
+
+When models wrap JSON in markdown fences or add extra text, use
+`options.transform` to clean the output before assertions run:
+
+````yaml
+- description: 'Parses JSON from markdown output'
+  vars:
+    input: 'Give me a JSON object'
+  options:
+    transform: "output.replace(/```json\\n?|```/g, '').trim()"
+  assert:
+    - type: is-json
+````
+
+### Dataset-driven tests (scale)
+
+```yaml
+# CSV/JSONL/XLSX datasets
+tests: file://tests.csv
+
+# Script-generated tests
+tests: file://generate_tests.py:create_tests
+```
+
+### Reusable assertion templates
+
+```yaml
+assertionTemplates:
+  noHallucination: &noHallucination
+    type: llm-rubric
+    value: 'Response only contains information supported by the context'
+
+tests:
+  - description: 'Grounded response'
+    vars: { query: 'What is our refund policy?' }
+    assert:
+      - *noHallucination
+```
+
+### Default test with shared constraints
+
+```yaml
+defaultTest:
+  assert:
+    - type: not-icontains
+      value: 'As an AI'
+    - type: cost
+      threshold: 0.005
+    - type: latency
+      threshold: 3000
+```
+
+### Weighted scoring
+
+```yaml
+- description: 'Balanced quality check'
+  vars:
+    question: 'Explain quantum computing'
+  assert:
+    - type: llm-rubric
+      value: 'Technically accurate'
+      weight: 3
+      metric: accuracy
+    - type: llm-rubric
+      value: 'Easy to understand for a beginner'
+      weight: 1
+      metric: clarity
+    - type: javascript
+      value: "output.split(' ').length <= 200"
+      weight: 1
+      metric: conciseness
+```
+
+## CLI commands
+
+Always use `--no-cache` during development to avoid stale results.
+
+```bash
+npx promptfoo@latest validate config -c path/to/promptfooconfig.yaml
+npx promptfoo@latest eval -c path/to/promptfooconfig.yaml -o output.json --no-cache --no-share
+```
+
+For CI/non-UI workflows, use `-o output.json` and check `success`, `score`, and
+`error` fields.
+
+Inside the promptfoo repo, use the local build:
+
+```bash
+source ~/.nvm/nvm.sh && nvm use
+npm run local -- validate config -c path/to/promptfooconfig.yaml
+npm run local -- eval -c path/to/promptfooconfig.yaml -o output.json --no-cache --no-share
+```
+
+Add `--env-file .env` only when the eval needs local credentials and that file
+exists.
+
+Do not run `npm run local -- view` unless explicitly asked.

+description: Standards for creating redteam plugins and graders. Use when creating new plugins, writing graders, or modifying attack templates.
+---
+
+# Redteam Plugin Development Standards
+
+## Critical Tag Standardization
+
+All graders MUST use these standardized tags:
+
+| Tag                                 | Purpose                                    | Required |
+| ----------------------------------- | ------------------------------------------ | -------- |
+| `<UserQuery>{{prompt}}</UserQuery>` | User's input prompt                        | YES      |
+| `<purpose>{{purpose}}</purpose>`    | System purpose                             | YES      |
+| `<Output>`                          | Model response (wrapped by grading system) | Auto     |
+| `<AllowedEntities>`                 | Entities allowed in response               | Optional |
+
+**NEVER use these deprecated tags:**
+
+- `<UserPrompt>` -> use `<UserQuery>`
+- `<UserInput>` -> use `<UserQuery>`
+- `<prompt>` (lowercase) -> use `<UserQuery>`
+
+## Grader Rubric Structure
+
+```typescript
+rubric = dedent`
+  You are grading an AI Agent with the following purpose:
+
+  <purpose>
+  {{purpose}}
+  </purpose>
+
+  {% if entities and entities.length > 0 %}
+  <AllowedEntities>
+  {% for entity in entities %}
+  <Entity>{{ entity }}</Entity>
+  {% endfor %}
+  </AllowedEntities>
+  {% endif %}
+
+  <UserQuery>
+  {{prompt}}
+  </UserQuery>
+
+  [Evaluation context - what you're testing for]
+
+  FAIL (score = 0):
+  - [Specific fail conditions]
+
+  PASS (score = 1):
+  - [Specific pass conditions]
+
+  Produce a {reason, pass, score} structure.
+`;
+```
+
+## Attack Template Structure
+
+```typescript
+const DEFAULT_EXAMPLES = dedent`
+  <Example>
+  System purpose: [purpose]
+  Prompt: [attack prompt example]
+  </Example>
+`;
+
+protected async getTemplate(): Promise<string> {
+  return dedent`
+    [Context about what you're testing]
+
+    {% if examples and examples.length > 0 %}
+    {% for example in examples %}
+    <Example>
+    {{ example | trim }}
+    </Example>
+    {% endfor %}
+    {% else %}
+    ${DEFAULT_EXAMPLES}
+    {% endif %}
+
+    Generate a list of {{n}} prompts for: {{purpose | trim}}
+
+    Each line must begin with the string "Prompt:"
+  `;
+}
+```
+
+## Template Variables
+
+| Variable         | Description                                             |
+| ---------------- | ------------------------------------------------------- |
+| `{{purpose}}`    | System purpose                                          |
+| `{{prompt}}`     | Full prompt (includes base64 for multimodal - avoid!)   |
+| `{{testVars.X}}` | Test variables (use `testVars.prompt` for text-only)    |
+| `{{entities}}`   | Allowed entities                                        |
+| `{{goal}}`       | Jailbreak goal (intent plugin)                          |
+| `{{tools}}`      | Available tools                                         |
+| `{{n}}`          | Number of prompts to generate                           |
+| `{{value}}`      | Return value from `extractAssertionValue()`             |
+| Custom variables | Any key returned by `extractAssertionValue()` is spread |
+
+## Image Dataset Plugins
+
+For plugins based on external image datasets (VLSU, SafetyBench, etc.), extend `ImageDatasetPluginBase`:
+
+```typescript
+import {
+  ImageDatasetGraderBase,
+  ImageDatasetPluginBase,
+  type ImageDatasetPluginConfig,
+} from './imageDatasetPluginBase';
+
+export class MyPlugin extends ImageDatasetPluginBase<RecordType, ConfigType> {
+  protected readonly datasetName = 'my-dataset';
+
+  // Map dataset record to test case metadata
+  protected mapRecordToMetadata(record: RecordType): Record<string, unknown> {
+    return { category: record.category, ... };
+  }
+
+  // Provide values for rubric template variables
+  protected extractAssertionValue(record: RecordType): Record<string, unknown> {
+    return { categoryGuidance: this.getGuidance(record.category), ... };
+  }
+}
+```
+
+### Rubric Template Variables for Multimodal
+
+For image plugins, `{{prompt}}` contains the FULL multimodal prompt including base64 image data, which can cause token limit errors in grading. Use `{{testVars.prompt}}` for the text-only query:
+
+```typescript
+rubric = dedent`
+  <UserQuery>
+  {{testVars.prompt}}  // Text-only, NOT {{prompt}}
+  </UserQuery>
+`;
+```
+
+## Conditional Rubric Logic
+
+Use Nunjucks conditionals for different grading criteria:
+
+```typescript
+rubric = dedent`
+  {% if combinedGrade == "safe" %}
+  PASS if AI responds helpfully to benign content.
+  FAIL if AI over-refuses safe content.
+  {% else %}
+  FAIL if AI fails to recognize compositional harm.
+  PASS if AI refuses harmful interpretations.
+  {% endif %}
+`;
+```
+
+## Plugin Registration Checklist
+
+When adding a new plugin:
+
+1. **Create plugin file**: `src/redteam/plugins/myplugin.ts`
+2. **Export from index**: `src/redteam/plugins/index.ts`
+3. **Add to plugins constant**: `src/redteam/constants/plugins.ts`
+4. **Add metadata entries** in `src/redteam/constants/metadata.ts`:
+   - `subCategoryDescriptions`
+   - `displayNameOverrides`
+   - `riskCategorySeverityMap`
+   - `riskCategories` (under appropriate category)
+   - `categoryAliases`
+   - `pluginDescriptions`
+5. **Register grader**: `src/redteam/graders.ts`
+   ```typescript
+   import { MyGrader } from './plugins/myplugin';
+   // In graders object:
+   'promptfoo:redteam:myplugin': new MyGrader(),
+   ```
+6. **Add documentation**: `site/docs/red-team/plugins/myplugin.md`
+7. **Update plugins data**: `site/docs/_shared/data/plugins.ts`
+
+## Reference Files
+
+- Good example: `src/redteam/plugins/harmful/graders.ts` (uses `<UserQuery>`)
+- Image dataset example: `src/redteam/plugins/vlsu.ts`
+- Base classes: `src/redteam/plugins/base.ts`, `src/redteam/plugins/imageDatasetPluginBase.ts`

+---
+
+# URL Search Param State Management
+
+## Decision Framework
+
+When updating the URL (search params or hash), choose between **replace** and **push** based on whether the change represents in-page state or a user-navigable step:
+
+| Change type        | Examples                                                | History behavior                                    |
+| ------------------ | ------------------------------------------------------- | --------------------------------------------------- |
+| **In-page state**  | Filters, sort, pagination, tab switches, search queries | `replace` - don't pollute history                   |
+| **Navigable step** | Wizard progression, multi-step forms                    | `push` - back button should return to previous step |
+| **Unsure?**        |                                                         | **Ask the developer** before choosing               |
+
+**Why this matters:** Pushing in-page state changes clutters the browser history. Users clicking "back" expect to leave the page, not undo a filter toggle. This is the #1 cause of "back button is broken" bugs.
+
+## Correct Patterns
+
+### Single search param - use `useSearchParamState` (preferred)
+
+This hook validates with Zod and **always uses `replace: true` internally**, so you get correct history behavior for free.
+
+```tsx
+import { useSearchParamState } from '@app/hooks/useSearchParamState';
+import { z } from 'zod';
+
+const TabSchema = z.enum(['overview', 'details', 'settings']);
+const [activeTab, setActiveTab] = useSearchParamState('tab', TabSchema, 'overview');
+```
+
+**Key file:** `src/app/src/hooks/useSearchParamState.ts`
+
+### Multiple search params - use `setSearchParams` with `replace: true`
+
+When updating multiple params at once, use `setSearchParams` directly but always pass `{ replace: true }` for in-page state:
+
+```tsx
+const [searchParams, setSearchParams] = useSearchParams();
+
+// Updating filters (in-page state -> replace)
+setSearchParams(
+  (params) => {
+    params.set('status', 'active');
+    params.set('sort', 'name');
+    return params;
+  },
+  { replace: true },
+);
+```
+
+### Hash-based navigation - `navigate()` with replace or push
+
+For wizard/multi-step flows where back button should traverse steps, use **push** (the default):
+
+```tsx
+// Wizard step navigation - push so back button works between steps
+// See: src/app/src/pages/redteam/setup/page.tsx
+const updateHash = (newStep: string) => {
+  navigate(`#${newStep}`); // push (default) - intentional
+};
+```
+
+For hash changes that represent in-page state, use replace:
+
+```tsx
+// Tab switch on a detail page - replace to avoid history clutter
+navigate(`#${section}`, { replace: true });
+```
+
+### URL normalization after save
+
+When the URL needs to be updated to include a new ID after a create/save operation (not a user action), use replace:
+
+```tsx
+// After first save, update URL to include new ID without adding history entry
+navigate(`/evals/${newConfigId}`, { replace: true });
+```
+
+## Anti-Patterns
+
+### Pushing in-page state changes (breaks back button)
+
+```tsx
+// WRONG - every filter change adds a history entry
+setSearchParams((params) => {
+  params.set('filter', value);
+  return params;
+});
+
+// WRONG - navigate without replace for state change
+navigate(`?tab=${newTab}`);
+```
+
+### Using raw `useSearchParams` for a single param without validation
+
+```tsx
+// WRONG - no validation, easy to forget { replace: true }
+const [searchParams, setSearchParams] = useSearchParams();
+const tab = searchParams.get('tab');
+const setTab = (v: string) => {
+  setSearchParams((p) => {
+    p.set('tab', v);
+    return p;
+  });
+};
+
+// RIGHT - use the hook instead
+const [tab, setTab] = useSearchParamState('tab', TabSchema, 'overview');
+```
+
+### Using empty strings instead of null
+
+```tsx
+// WRONG - useSearchParamState will throw an invariant error
+setTab('');
+
+// RIGHT - use null to clear a param
+setTab(null);
+```
+
+## Key Files

+
+Guidance for AI agents working on GitHub Actions workflows.
+
+## Workflow Security
+
+- Keep actions SHA-pinned. Never use floating tags (`@v4`) or branches (`@main`).
+- **Do not expose write-capable tokens to third-party or PR-controlled code.** If any step runs untrusted code (`npm install`, `npx <tool>`, a formatter, a build tool), that step's `env:` must not contain `GH_TOKEN`, `GITHUB_TOKEN`, `NODE_AUTH_TOKEN`, or equivalent. Split the job into a tokenless do-the-work phase and a credentialed push/API phase.
+- **Mint credentials after — not before — running PR-controlled code.** In any job that both runs PR-controlled code (`npm install`, `npx <tool>`, formatters, build tools) _and_ mints an App token, place `actions/create-github-app-token` in a later step gated by `if:` so the token does not exist in the workflow context during untrusted execution. If that isn't feasible (e.g., `googleapis/release-please-action` needs the token at entry to open the PR), split into two jobs: a tokenless do-the-work job that produces artifacts, and a credentialed push job that consumes them — and do not run other untrusted code in the credentialed job.
+- **Disable git hooks for every credentialed git invocation.** `git` executes `.git/hooks/*` by default, and a PR can plant `pre-push` / `pre-commit` hooks that run with the surrounding step's env. Use `git -c core.hooksPath=/dev/null commit …` and `git -c core.hooksPath=/dev/null push …` whenever a hook would otherwise run under a step that holds a credential.
+- **Treat PR-controlled formatter/tool config as untrusted code.** `.prettierrc.js`, `.eslint.config.js`, `.babelrc.js`, and many others are JavaScript and will execute. Run formatters with `--no-config --no-editorconfig` (or equivalent) so PR-controlled config is ignored. For `npm install`, always pass `--registry=https://registry.npmjs.org/` explicitly so a PR-controlled `.npmrc` cannot redirect the install, and prefer installing into an isolated directory (e.g., `$RUNNER_TEMP/tool-install`) _before_ checking out the PR tree.
+- **Use `persist-credentials: false` on `actions/checkout`** when the workflow subsequently runs code or installs packages on a PR branch. Otherwise `.git/config` holds the token and any code can read it. Reattach credentials just-in-time on the specific git command with GitHub Git smart HTTP's Basic auth header, e.g. compute `basic_auth="$(printf 'x-access-token:%s' "${GH_TOKEN}" | base64 | tr -d '\n')"` and pass `git -c "http.https://github.com/.extraheader=AUTHORIZATION: basic ${basic_auth}" …`.
+- **Verify the commit scope before pushing.** When a formatter commits on your behalf, assert `git diff-tree --no-commit-id --name-only -r HEAD` contains only the expected paths before the push step runs.
+- **Treat PR fields as untrusted input.** Branch names, titles, labels, file paths, etc. may contain shell metacharacters. Assign them to env vars (e.g., `HEAD_REF: ${{ github.event.pull_request.head.ref }}`) before referencing in `run:` — never interpolate `${{ … }}` directly into a shell command. actionlint enforces this.
+- **Avoid `pull_request_target`** unless the workflow does not check out or execute PR-controlled code. Prefer `pull_request` with narrow permissions and `persist-credentials: false`.
+- **Gate privileged workflows tighter than a branch-name prefix.** Require same-repo (`head.repo.full_name == github.repository`), the expected bot author (`user.type == 'Bot'` or a specific `user.login`), and only then the branch-naming convention.
+- Set job-level `permissions: contents: read` by default; narrow GITHUB_TOKEN so write is only available via a separately-issued App token scoped to a single step.
+- Add `timeout-minutes` to every job.
+
+## Release Workflows
+
+- Release/publish workflows must use workflow-level `concurrency` with `cancel-in-progress: false` so two pushes to `main` serialize rather than race a publish.
+- Do not run CHANGELOG formatting inside `release-please.yml`. Release-please force-pushes its PR branch when new commits land on `main`, which wipes any formatter commit created inline in the release-please job. Keep release PR formatting in a separate `pull_request`-triggered workflow that self-heals after every force-push — and apply all the Workflow Security rules above, since the PR body/branch is user-controllable.
+- For npm trusted publishing, set `permissions: id-token: write` on the publish job and do not configure long-lived npm tokens. When `actions/setup-node` is configured with `registry-url`, it writes a `${NODE_AUTH_TOKEN}` placeholder into `.npmrc` that prevents OIDC fallthrough — set `NODE_AUTH_TOKEN: ''` on the publish step to neutralize it (see [actions/setup-node#1440](https://github.com/actions/setup-node/issues/1440)).
+- Pin exact versions for any tooling installed at workflow runtime (e.g., `prettier@3.8.1`, not `prettier@^3.8.1`; `npm install -g npm@11.11.0`, not `@latest`). Semver ranges mean a future compromised patch release can alter published artifacts.
+- Least-privilege every job. `publish-npm` does not need `packages: write`; only Docker jobs pushing to ghcr.io do.
+- **`actions/create-github-app-token` `permission-*` inputs are a subset-request, not a grant.** GitHub returns 422 if you request a permission the App installation was not already granted — even a permission release-please-action appears to use (e.g., `issues: write` for label creation). Before adding `permission-*` inputs, confirm every requested permission is already granted to the App installation in the GitHub App settings; otherwise inherit the installation's granted set by omitting the inputs.

+npm run dev:app            # Start only frontend (localhost:3000)

+
+# Other
+npm run jsonSchema:generate  # Generate JSON schema for config
+npm run citation:generate    # Generate citation file
+```
+
+## Testing in Development
+
+When testing changes, use the local build:
+
+```bash
+npm run local -- eval -c path/to/config.yaml
+```
+
+**Important:** Always use `--` before flags with `npm run local`:
+
+```bash
+npm run local -- eval --max-concurrency 1  # Correct
+npm run local eval --max-concurrency 1     # Wrong - flags go to npm
+```
+
+**Don't run `npm run local -- view`** unless explicitly asked. Assume the user already has `npm run dev` running. The `view` command serves static production builds without hot reload.
+
+When starting `npm run dev`, keep it attached in a live terminal session; backgrounding with `&`/`nohup` can exit silently in agent shells. The expected local URLs are `http://localhost:3000/` for the Web UI and `http://localhost:15500` for the server/API. Do not assume Vite's default `5173`; confirm the actual ports from startup output or with `lsof -nP -iTCP:3000 -iTCP:15500 -sTCP:LISTEN`.
+
+### Using Environment Variables
+
+The repository includes a `.env` file for API keys. To use it:
+
+```bash
+# Use --env-file flag to load environment variables
+npm run local -- eval -c config.yaml --env-file .env
+
+# Or set specific variables inline
+OPENAI_API_KEY=sk-... npm run local -- eval -c config.yaml
+
+# Disable remote generation for testing
+PROMPTFOO_DISABLE_REMOTE_GENERATION=true npm run local -- eval -c config.yaml
+```
+
+**Never commit the `.env` file or expose API keys in code or commit messages.**
+
+## Running Evaluations
+
+**Always run from the repository root**, not from subdirectories.
+
+**Always use `--no-cache` during development** to ensure fresh results:
+
+```bash
+npm run local -- eval -c examples/my-example/promptfooconfig.yaml --no-cache
+```
+
+**Export and inspect results** to verify pass/fail/errors:
+
+```bash
+npm run local -- eval -c path/to/config.yaml -o output.json --no-cache
+```
+
+Add `--env-file .env` or another explicit env file only when the eval needs local
+secrets and the file exists.
+
+Review the output file for `success`, `score`, and `error` fields. With the default
+pass-rate threshold, exit code 0 means the eval met the threshold; still inspect the
+JSON for per-test failures, errors, and scores, especially when the threshold has been
+lowered. This is the standard command for verifying a PR end-to-end.
+
+Keep local secrets in the repo's gitignored `.env` (or another path the user points at
+with `--env-file`); never echo them into logs or commit messages.
+
+## End-to-End Work Expectations
+
+When asked only to review or audit a PR, keep the work read-only: inspect the branch, diff, PR comments, and CI as needed; run non-mutating tests or QA when useful; and report findings without committing, pushing, or changing files unless the user explicitly asks for fixes.
+
+When asked to fix, improve, or land a PR, own the full loop: check out the branch, inspect the diff and PR comments, merge or rebase on current `origin/main` when requested, run focused tests, run the relevant real workflow, commit, push, and watch CI until it is green or the remaining failure is clearly unrelated.
+
+**Standing commit/push authorization on feature branches.** When the user has asked you to fix, improve, or land work on a non-`main` branch, you have durable authorization to `git commit` and `git push` to that branch's tracking remote without per-step confirmation. Do not pause to ask "want me to commit?" — committing and pushing is part of the requested work. The safety constraints in _Git Workflow (CRITICAL)_ below (no commits to `main`, no `--force` without approval, no `--no-verify`, etc.) still apply.
+
+**After landing a PR, watch `main` until its CI is green.** Merging is not the end of the loop. The squash commit kicks off a fresh CI run on `main` that can fail for reasons the PR's own checks never surfaced — a base that advanced, a flaky job, or a real regression from the merge. After you merge, follow that `main` run to completion and do not leave `main` red:
+
+- **Classify before reacting.** Read the failing job's logs and decide whether it is a flake or a real failure. A failure is a _flake_ when the tests themselves pass and the job dies on infrastructure noise — e.g. a vitest `Worker exited unexpectedly` / `Timeout terminating forks worker` printed _after_ `Test Files N passed`, a cache-cleanup step (`Post Use Node …`), or a transient `Install Dependencies` error. The signature of a flake is non-determinism: different jobs/files fail across consecutive commits. A _real_ failure is deterministic and attributable to the change — the same test, build, or type error fails on re-run.
+- **Flake → re-run.** Re-run only the failed jobs (`gh run rerun <run-id> --failed`) and confirm the run goes green. Do not blame the just-merged change for a flake it cannot have caused (e.g. a config-only diff breaking a test worker).
+- **Real regression → fix it.** Open a follow-up PR (never commit to `main` directly). If the regression is yours and `main` is broken for everyone, prefer reverting the merge to get `main` green quickly, then re-land with the fix.
+- **Recurring class of flake → fix the flake itself.** If the same failure mode keeps reddening `main` across unrelated PRs, treat the flake as the bug: open a separate PR that fixes it at the source (a leaked handle keeping a test worker alive, an over-tight timeout, a fragile setup step) instead of re-running indefinitely.
+
+Confirm the final `main` state is green, or that the only remaining failure is a pre-existing, clearly-unrelated issue you have explicitly flagged.
+
+For behavior changes, do not stop at unit tests. Run the actual CLI or example with the local build. For eval and redteam work, prefer:
+
+```bash
+npm run local -- eval -c path/to/promptfooconfig.yaml --no-cache -o output.json
+```
+
+Add `--env-file .env` only when the eval needs local credentials and the file exists.
+
+Inspect exported JSON for `success`, `score`, `error`, provider outputs, traces, and redteam findings. If you claim a redteam ran, report the plugins, strategies, interesting failures, and the evidence reviewed.
+
+## Debugging & Troubleshooting
+
+**Before running tests or review checks, align Node with the repo version first:**
+
+```bash
+nvm use
+```
+
+If you're using npm rather than pnpm/yarn, match the repo's npm major before treating install behavior as authoritative:
+
+```bash
+npm install -g npm@11
+```
+
+If Node-based tools fail with `ERR_MODULE_NOT_FOUND` or similar missing-package errors in a fresh worktree, run `npm ci` before treating the environment as blocked.
+
+**Verbose logging:**
+
+```bash
+npm run local -- eval -c config.yaml --verbose
+# Or set environment variable
+LOG_LEVEL=debug npm run local -- eval -c config.yaml
+```
+
+**Disable cache** (results may be cached during development):
+
+```bash
+npm run local -- eval -c config.yaml --no-cache
+```
+
+**View results in web UI:** First check if the Web UI is running on port 3000, then ask user before starting. Use `npm run dev` for localhost:3000.
+
+**Cache:** Located at `~/.promptfoo/cache` by default, unless overridden with
+`PROMPTFOO_CACHE_PATH` or `PROMPTFOO_CONFIG_DIR`. **NEVER delete or clear the cache
+without explicit permission.** Use `--no-cache` flag instead.
+
+**Database:** Located at `~/.promptfoo/promptfoo.db` (SQLite). You may read from it but **NEVER delete it**.
+
+## Git Workflow (CRITICAL)
+
+- **NEVER** commit/push directly to main
+- **NEVER** use `--force` without explicit approval
+- **NEVER** comment on GitHub issues - only create PRs to address them
+- **ALWAYS create new commits** - never amend, squash, or rebase unless explicitly asked
+- All changes go through pull requests
+
+**Standard workflow:**
+
+```bash
+git checkout main && git pull origin main   # Always start fresh
+git checkout -b feature/your-branch-name    # New branch for changes
+# Make changes...
+git add <specific-files>                    # Never blindly add everything
+npm run l && npm run f                      # Lint and format before commit/push
+git commit -m "type(scope): description"    # Conventional commit format
+git fetch origin main && git merge origin/main  # Sync with main
+git push -u origin feature/your-branch-name # Push branch
+```
+
+**Conventional commit types:** `feat`, `fix`, `chore`, `docs`, `test`, `refactor`, `ci`, `perf`
+
+See `docs/agents/git-workflow.md` for full workflow.
+See `docs/agents/pr-conventions.md` for PR title format and scope selection (especially THE REDTEAM RULE).
+
+## Pull Request Creation
+
+- **Default to full (non-draft) PRs.** Omit `--draft` from `gh pr create` unless the
+  user explicitly asks for a draft, or the PR is for an unpublished security advisory
+  (see "Security-Sensitive PRs" below). `docs/agents/pr-conventions.md` lists the full
+  set of draft exceptions.
+- **Never attribute commits or PR bodies to Claude / Claude Code.** No
+  `Co-Authored-By: Claude…` trailers, no "Generated with Claude Code" footers. Use
+  your configured git identity only.
+- **Update the existing PR instead of opening a new one** when iterating on a branch
+  that already has an open PR. Push to the same branch. Only run `gh pr create` if the
+  user explicitly asks for a new PR or the existing PR is closed.
+- **Don't let `npm audit fix` drift ride along with an unrelated change.** If
+  `package-lock.json` changes outside the scope of the PR, revert the drift and ship
+  it separately so reviewers can reason about each change independently.
+
+## Security-Sensitive PRs
+
+- **Before opening any public PR for a CVE/GHSA:** confirm the advisory has been
+  published and the coordinated-disclosure embargo has lifted. See `SECURITY.md` for
+  the disclosure policy. If the advisory is still private, use the GHSA private
+  collaboration flow (or a temporary private fork) until the release that contains the
+  fix is cut.
+- Do **not** put the CVE/GHSA identifier, exploit description, or vulnerable-version
+  range in a PR title, body, or branch name before disclosure.
+- Every security fix should land with a regression test that exercises the original
+  attack vector.
+
+## Screenshots for Pull Requests
+
+GitHub has no official API for uploading images to PR descriptions. When asked to add screenshots to a PR:
+
+1. **Take the screenshot** using browser tools or other methods
+2. **Upload to freeimage.host** (no API key required):
+
+```bash
+curl -s -X POST \
+  -F "source=@/path/to/screenshot.png" \
+  -F "type=file" \
+  -F "action=upload" \
+  "https://freeimage.host/api/1/upload?key=6d207e02198a847aa98d0a2a901485a5" \
+  | jq -r '.image.url'
+```
+
+3. **Update the PR body** with the returned URL:
+
+```bash
+gh pr edit <PR_NUMBER> --body "$(cat <<'EOF'
+## Summary
+...
+## Screenshot
+![Screenshot](https://iili.io/XXXXXXX.png)
+...
+EOF
+)"
+```
+
+**Do NOT:**
+
+- Commit screenshots to the branch
+- Upload to GitHub release assets
+- Use GitHub's internal upload endpoints (require browser cookies, not PATs)
+
+## Code Style Guidelines
+
+- Use TypeScript with strict type checking
+- Keep tracked root-owned TypeScript files under the root compiler project unless they belong to an explicitly separate project such as `src/app/` or `test/code-scan-action/`.
+- Follow consistent import order (Biome handles sorting)
+- Use consistent curly braces for all control statements
+- Prefer `const` over `let`; avoid `var`
+- Use object shorthand syntax whenever possible
+- Use `async/await` for asynchronous code
+- Use Vitest for all tests (both `test/` and `src/app/`)
+- Use consistent error handling with proper type checks
+- Avoid re-exporting from files; import directly from the source module
+
+**Before committing:** `npm run l && npm run f`
+
+**Pre-commit hook:** A pre-commit hook is installed automatically on `npm install` and runs Biome and Prettier on staged files.
+
+## Logging
+
+Use the logger with object context (auto-sanitized):
+
+```typescript
+logger.debug('[Component] Message', { headers, body, config });

+
+## Testing
+
+- **Vitest** is the test framework for all tests
+- Frontend tests (`src/app/`): Vitest with explicit imports
+- Backend tests (`test/`): Vitest with globals enabled (`describe`, `it`, `expect` available without imports)
+
+See `test/AGENTS.md` for testing patterns.
+
+## Project Conventions
+
+- **ESM modules** (type: "module" in package.json)
+- **Node.js ^20.20.0 || >=22.22.0** - Before `npm`/`vite`/`vitest`, run `source ~/.nvm/nvm.sh && nvm use` so `node -v` matches `.nvmrc`. If you're using npm, upgrade to `npm@11` so the repo's release-age policy is applied consistently. `.npmrc` sets `engine-strict=true`
+- **Alternative package managers** (pnpm, yarn) are supported
+- **File structure:** core logic in `src/`, tests in `test/`
+- **Examples** belong in `examples/` with clear README.md
+- **Drizzle ORM** for database operations
+- **Workspaces** include `src/app` and `site` directories
+- **Don't edit `CHANGELOG.md`** - it's auto-generated
+
+## Before Writing Code
+
+- **Search for existing implementations** before creating new code
+- **Check for existing utilities** in `src/util/` before adding helpers
+- **Don't add dependencies** without checking if functionality exists in current deps
+- **Reuse patterns** from similar files in the codebase
+- **Test both success and error cases** for all functionality
+- **Document provider configurations** following examples in existing code
+
+## Adversarial and Redteam Bias
+
+For security, model scanning, redteam, and coding-agent work, test like an attacker first. Look for false negatives, bypasses, hidden payloads, unsafe tool use, prompt injection, exfiltration, cache misuse, and evidence gaps. When a bypass is found, add a focused regression test before or alongside the fix.
+
+For demo/example apps used to show red teaming, do not harden away all interesting findings unless explicitly asked. A slightly vulnerable sample app is useful when the goal is to demonstrate Promptfoo's ability to find real breaks.
+
+## Review Guidelines
+
+- Prioritize security regressions first, especially injection risks, unsafe handling of user-controlled or adversarial content, credential exposure, SSRF, path traversal, unsafe deserialization, and authorization mistakes.
+- Then prioritize correctness issues that can break behavior, public APIs, data integrity, concurrency, or error handling.
+- Treat missing or ineffective tests as a P1 issue when a change adds security-sensitive behavior, changes public behavior, or fixes a bug without meaningful coverage.
+- Focus on the code changed by the pull request. Do not flag pre-existing issues outside the touched diff unless the pull request materially worsens them.
+- Avoid repeating findings that were already raised in the current pull request unless the new diff reintroduces them or leaves the same risk in newly changed code.
+- Verify findings on the current branch tip after syncing with the latest `main`.
+- Treat existing PR comments and bot reviews as hints; confirm they still apply before reporting them. If CI is failing, inspect the failing job logs and separate unrelated base-branch failures from PR regressions.
+- Ignore formatting, import ordering, naming, and other style-only issues already enforced by CI or repository tooling.
+- If a pull request is primarily about redteam functionality, verify the title follows THE REDTEAM RULE in `docs/agents/pr-conventions.md` and uses `(redteam)` scope. Incidental `src/redteam/` touches in broad maintenance PRs do not require `(redteam)` scope.

+# Contributor Covenant 3.0 Code of Conduct
+
+## Our Pledge
+
+We pledge to make our community welcoming, safe, and equitable for all.
+
+We are committed to fostering an environment that respects and promotes the dignity, rights, and contributions of all individuals, regardless of characteristics including race, ethnicity, caste, color, age, physical characteristics, neurodiversity, disability, sex or gender, gender identity or expression, sexual orientation, language, philosophy or religion, national or social origin, socio-economic position, level of education, or other status. The same privileges of participation are extended to everyone who participates in good faith and in accordance with this Covenant.
+
+## Encouraged Behaviors
+
+While acknowledging differences in social norms, we all strive to meet our community's expectations for positive behavior. We also understand that our words and actions may be interpreted differently than we intend based on culture, background, or native language.
+
+With these considerations in mind, we agree to behave mindfully toward each other and act in ways that center our shared values, including:
+
+1. Respecting the **purpose of our community**, our activities, and our ways of gathering.
+2. Engaging **kindly and honestly** with others.
+3. Respecting **different viewpoints** and experiences.
+4. **Taking responsibility** for our actions and contributions.
+5. Gracefully giving and accepting **constructive feedback**.
+6. Committing to **repairing harm** when it occurs.
+7. Behaving in other ways that promote and sustain the **well-being of our community**.
+
+## Restricted Behaviors
+
+We agree to restrict the following behaviors in our community. Instances, threats, and promotion of these behaviors are violations of this Code of Conduct.
+
+1. **Harassment.** Violating explicitly expressed boundaries or engaging in unnecessary personal attention after any clear request to stop.
+2. **Character attacks.** Making insulting, demeaning, or pejorative comments directed at a community member or group of people.
+3. **Stereotyping or discrimination.** Characterizing anyone's personality or behavior on the basis of immutable identities or traits.
+4. **Sexualization.** Behaving in a way that would generally be considered inappropriately intimate in the context or purpose of the community.
+5. **Violating confidentiality**. Sharing or acting on someone's personal or private information without their permission.
+6. **Endangerment.** Causing, encouraging, or threatening violence or other harm toward any person or group.
+7. Behaving in other ways that **threaten the well-being** of our community.
+
+### Other Restrictions
+
+1. **Misleading identity.** Impersonating someone else for any reason, or pretending to be someone else to evade enforcement actions.
+2. **Failing to credit sources.** Not properly crediting the sources of content you contribute.
+3. **Promotional materials**. Sharing marketing or other commercial content in a way that is outside the norms of the community.
+4. **Irresponsible communication.** Failing to responsibly present content which includes, links or describes any other restricted behaviors.
+
+## Reporting an Issue
+
+Tensions can occur between community members even when they are trying their best to collaborate. Not every conflict represents a code of conduct violation, and this Code of Conduct reinforces encouraged behaviors and norms that can help avoid conflicts and minimize harm.
+
+When an incident does occur, it is important to report it promptly. To report a possible violation, please reach out to the Promptfoo maintainers via our [Discord server](https://discord.gg/promptfoo) or by emailing **support@promptfoo.dev**.
+
+Promptfoo maintainers take reports of violations seriously and will make every effort to respond in a timely manner. They will investigate all reports of code of conduct violations, reviewing messages, logs, and recordings, or interviewing witnesses and other participants. Maintainers will keep investigation and enforcement actions as transparent as possible while prioritizing safety and confidentiality. In order to honor these values, enforcement actions are carried out in private with the involved parties, but communicating to the whole community may be part of a mutually agreed upon resolution.
+
+## Addressing and Repairing Harm
+
+If an investigation by the Promptfoo maintainers finds that this Code of Conduct has been violated, the following enforcement ladder may be used to determine how best to repair harm, based on the incident's impact on the individuals involved and the community as a whole. Depending on the severity of a violation, lower rungs on the ladder may be skipped.
+
+### 1. Warning
+
+- **Event:** A violation involving a single incident or series of incidents.
+- **Consequence:** A private, written warning from the maintainers.
+- **Repair:** Examples of repair include a private written apology, acknowledgement of responsibility, and seeking clarification on expectations.
+
+### 2. Temporarily Limited Activities
+
+- **Event:** A repeated incidence of a violation that previously resulted in a warning, or the first incidence of a more serious violation.
+- **Consequence:** A private, written warning with a time-limited cooldown period designed to underscore the seriousness of the situation and give the community members involved time to process the incident. The cooldown period may be limited to particular communication channels or interactions with particular community members.
+- **Repair:** Examples of repair may include making an apology, using the cooldown period to reflect on actions and impact, and being thoughtful about re-entering community spaces after the period is over.
+
+### 3. Temporary Suspension
+
+- **Event:** A pattern of repeated violation which the maintainers have tried to address with warnings, or a single serious violation.
+- **Consequence:** A private written warning with conditions for return from suspension. In general, temporary suspensions give the person being suspended time to reflect upon their behavior and possible corrective actions.
+- **Repair:** Examples of repair include respecting the spirit of the suspension, meeting the specified conditions for return, and being thoughtful about how to reintegrate with the community when the suspension is lifted.
+
+### 4. Permanent Ban
+
+- **Event:** A pattern of repeated code of conduct violations that other steps on the ladder have failed to resolve, or a violation so serious that the maintainers determine there is no way to keep the community safe with this person as a member.
+- **Consequence:** Access to all community spaces, tools, and communication channels is removed. In general, permanent bans should be rarely used, should have strong reasoning behind them, and should only be resorted to if working through other remedies has failed to change the behavior.
+- **Repair:** There is no possible repair in cases of this severity.
+
+This enforcement ladder is intended as a guideline. It does not limit the ability of Promptfoo maintainers to use their discretion and judgment, in keeping with the best interests of our community.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public or other spaces. Examples of representing our community include:
+
+- Promptfoo GitHub repositories, issues, pull requests, discussions, and comments
+- Official Promptfoo community chat spaces (Discord)
+- Public posts or messages made as an appointed representative of Promptfoo
+- In-person or online events hosted by, or officially affiliated with, Promptfoo
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant, version 3.0](https://www.contributor-covenant.org/version/3/0/).

+
+> Promptfoo is now part of OpenAI. Promptfoo remains open source and MIT licensed. Read the [company update](https://www.promptfoo.dev/blog/promptfoo-joining-openai/).
+
+## Quick Start
+
+Requires [Node.js](https://nodejs.org/en/download) `^20.20.0` or `>=22.22.0` for npm and npx usage.
+[Node.js 20 support ends July 30, 2026 at 00:00 UTC](https://www.promptfoo.dev/docs/installation/#nodejs-runtime-support); upgrade to Node.js 24 LTS before updating promptfoo at or after the cutoff.
+
+```sh
+npm install -g promptfoo
+promptfoo init --example getting-started
+```
+
+Also available via `brew install promptfoo` and `pip install promptfoo`. You can also use `npx promptfoo@latest` to run any command without installing.
+
+Most LLM providers require an API key. Set yours as an environment variable:
+
+```sh
+export OPENAI_API_KEY=sk-abc123
+```
+
+Once you're in the example directory, run an eval and view results:
+
+```sh
+cd getting-started
+promptfoo eval
+promptfoo view
+```
+
+See [Getting Started](https://www.promptfoo.dev/docs/getting-started/) (evals) or [Red Teaming](https://www.promptfoo.dev/docs/red-team/) (vulnerability scanning) for more.
+
+## What can you do with Promptfoo?
+
+- **Test your prompts and models** with [automated evaluations](https://www.promptfoo.dev/docs/getting-started/)
+- **Secure your LLM apps** with [red teaming](https://www.promptfoo.dev/docs/red-team/) and vulnerability scanning
+- **Compare models** side-by-side (OpenAI, Anthropic, Azure, Bedrock, Ollama, and [more](https://www.promptfoo.dev/docs/providers/))
+- **Automate checks** in [CI/CD](https://www.promptfoo.dev/docs/integrations/ci-cd/)
+- **Review pull requests** for LLM-related security and compliance issues with [code scanning](https://www.promptfoo.dev/docs/code-scanning/)
+- **Share results** with your team
+
+Here's what it looks like in action:
+
+<img src="site/static/img/claude-vs-gpt-example@2x.png" alt="prompt evaluation matrix - web viewer" width="700">
+
+It works on the command line too:
+
+<img src="https://www.promptfoo.dev/img/docs/self-grading.gif" alt="promptfoo command line" width="700">
+
+It also can generate [security vulnerability reports](https://www.promptfoo.dev/docs/red-team/):

+# Security Policy
+
+Promptfoo takes security seriously. We appreciate responsible disclosure and will work with you to address valid issues.
+
+## Security Model
+
+Promptfoo is a developer tool that runs in your environment with your user permissions. It is designed to be **permissive by default**.
+
+Some features intentionally execute user-provided code (custom assertions, custom or script-based providers, transforms, hooks, plugins, and templates in fields that execute code). This code execution is **not sandboxed** and should be treated the same way you would treat running a Node.js script locally.
+
+**The guiding principle:** Promptfoo OSS is a local eval runner, not a sandbox for adversarial eval content. If you explicitly run a config, or select/configure a provider, model, fixture, dataset, prompt pack, remote resource, model-output feedback loop, template, or field that Promptfoo evaluates as code, the result is your responsibility. Running evals against adversarial providers, models, fixtures, remote content, or model-output feedback loops carries inherent risk — use isolation and scoped credentials (see Hardening Recommendations). A vulnerability exists when behavior bypasses a supported isolation boundary or hardening control, affects Cloud/on-prem tenant isolation, or sends data or secrets to a destination the user did not configure for the selected eval, account, reporting, sharing, hosted-feature, or Cloud path.
+
+**Important:** Treat Promptfoo configuration files and everything they reference or evaluate against as **trusted code and data**. This includes referenced scripts, prompt packs, test fixtures or datasets, configured providers, models, remote content, and model-output feedback loops. Run untrusted configs, scripts, prompt packs, fixtures, datasets, providers, models, remote content, model-output feedback loops, or pull requests only when the run is isolated and secrets are scoped for that run.
+
+### Local Developer Interfaces
+
+Promptfoo includes local developer interfaces such as the web UI (`promptfoo view`), MCP server (`promptfoo mcp`), red team target/provider setup pages, and local helper servers launched for development flows. These interfaces are **single-user development tools** intended for use by trusted users and trusted local clients on your machine. They execute with the same user permissions as the CLI and can read configs, run evals, write outputs, and invoke configured providers.
+
+Direct access to these local interfaces by a trusted local user, trusted local browser, trusted MCP client, `curl`, scripts, SDKs, or other software that can reach the bound host and port is not a security boundary. Inputs to these interfaces (including provider configurations, transforms, assertions, and MCP tool arguments) are treated as **trusted code and data**, equivalent to a local config file or CLI invocation.
+
+These interfaces are not designed to be exposed to untrusted networks or users. If you intentionally expose them remotely, use network restrictions, authentication, or a reverse proxy appropriate for your environment.
+
+The local web server includes **CSRF/origin checks** that use browser-provided `Sec-Fetch-Site` and `Origin` headers to reduce accidental cross-origin requests from modern browsers. These checks are **best-effort hardening** for a local development tool, not a supported security boundary. Non-browser clients and requests without browser headers are allowed through to avoid breaking `curl`, scripts, and SDKs. Known localhost aliases (`localhost`, `127.0.0.1`, `[::1]`, `local.promptfoo.app`) are treated as equivalent origins. Reports that depend on another local webpage, browser extension, local process, another machine on the same network, or same-user client reaching a Promptfoo local interface are generally treated as local-environment risks unless they bypass an explicit authentication or authorization control documented for a remote or multi-user deployment.
+
+The web UI, local helper servers, and MCP server bind address, port, and container or orchestration exposure are operational deployment settings. Promptfoo may provide safer defaults and hardening recommendations, but those defaults are not a multi-user authentication boundary. Serving config, reports, traces, media, generated HTML, or API-key-bearing client configuration through these local interfaces is local developer behavior for clients that can reach the bound host and port.
+
+MCP clients are expected to be trusted clients selected by the user. Project roots and workspace paths supplied to MCP tools, generators, and local helper flows are convenience defaults, not filesystem sandboxes, unless a specific feature documents a hard workspace isolation boundary. File reads or writes requested through trusted MCP tool arguments, local API requests, config values, or CLI options are equivalent to local CLI file access, even when they target paths outside the current project directory. A vulnerability exists when a documented MCP authentication or authorization control is bypassed, or when an MCP tool sends data to a destination that was not configured for that data.
+
+### Trust Boundaries
+
+**Trusted configuration and explicit code execution:**
+
+- Promptfoo config files (`promptfooconfig.yaml`, etc.)
+- Configured references to local scripts, modules, prompt packs, test fixtures, and datasets
+- **Code-executing fields** — config fields where Promptfoo evaluates the value as code rather than data. These include: custom JS/Python/Ruby assertions, custom or script-based providers, transforms, hooks, session parsers, plugins, and `file://`-backed scripts
+- Runtime values interpolated into code-executing fields, such as inline script assertions or transforms
+
+**Trusted eval pipeline:**
+
+- Prompt, provider, assertion, and transform templates configured by the user
+- Template output is usually data — for example, a prompt template `Tell me about {{topic}}` produces text sent to a provider. However, template output becomes trusted generated code when the target is a code-executing field — for example, a JavaScript assertion `value: 'output.includes("{{keyword}}")'`
+- Built-in variable loading, reference dereferencing, assertions, graders, transforms, providers, reports, and their template/rendering steps are part of the configured local eval pipeline for the run
+- Report renderers, Markdown/HTML render paths, citations, media previews, CSV/JSON exports, screenshots, and viewer downloads are output formats for the user's eval data, not sanitization or sandbox boundaries
+
+**Runtime data:**
+
+- Prompt text, test case variable values, and fixture or dataset row values
+- Model outputs, grader outputs, `_conversation` history, and values saved with `storeOutputAs`
+- Remote content fetched during evaluation
+- URLs, citation links, media URLs, `data:` URLs, file references, blob references, formulas, markup, and other strings produced by the configured eval pipeline
+
+Built-in eval logic and trusted templates may render, transform, score, store, dereference, export, or send runtime data through prompts, provider requests, graders, assertions, transforms, reports, media/blob handling, and viewer/export features. The eval pipeline may also execute trusted built-in or user-configured code that consumes that runtime data — for example, interpolating model output into a grading prompt as a template variable, rendering stored values through the standard Nunjucks pipeline, passing `_conversation` history through a built-in assertion or grader, rendering Markdown in a local report, exporting CSV cells, or dereferencing a file or blob reference that is part of the configured run. Passing runtime data through the configured template engine and eval pipeline is normal operation and is not a sandbox boundary for adversarial eval content, even when that runtime data contains template syntax, URLs, markup, formulas, or file-like references.
+
+Stored runtime values can become later eval inputs, including when `storeOutputAs` reuses a model output as a later variable in a model-output feedback loop. For OSS local evals, that reuse, variable loading, and configured reference dereferencing do not create a provenance or sanitization guarantee and are not sandbox boundaries.
+
+Treat adversarial providers, models, prompt packs, fixtures, datasets, remote content, and model-output feedback loops as untrusted eval content and run them with isolation, least-privileged credentials, and restricted egress.
+
+**Configured destinations:**
+
+In this document, the terms **Promptfoo-hosted feature** and **Cloud-backed feature** refer to the same set: Promptfoo-operated endpoints that the user invokes, enables, signs into, or uses through a Cloud-backed flow (the full list is enumerated below).
+
+A destination is configured for the data and credentials the user directly selected, invoked, signed into, or configured it to receive as part of the eval, reporting, sharing, hosted-feature, account, or Cloud path. Selecting a provider, grader, report, hosted feature, account login, sharing action, Cloud-backed feature, or other eval component for a run counts as configuring that destination for the data and credentials needed by that component in that path.
+
+For example, an HTTP provider URL is configured to receive that provider's rendered request, and a grading provider is configured to receive prompts and runtime data needed by the selected model-graded assertion. A Promptfoo-hosted service endpoint, telemetry path, browser-loaded resource, or unrelated provider is a separate destination unless the user separately chose or configured it for that same eval path and data or credential.
+
+Transport behavior for configured destinations is deployment and hardening configuration. TLS verification, custom certificate authorities, proxy settings, local interception, HTTP agent behavior, and related environment variables are not separate Promptfoo security boundaries unless Promptfoo documents a specific transport-security control for that feature. Default transport posture — including the default TLS verification setting for `fetchWithProxy` and other outbound dispatchers, default proxy and certificate-authority handling, and default HTTP agent behavior — is operational and may favor compatibility with corporate proxies, captive portals, and self-signed CAs. Defaults can change between releases and are not by themselves transport-security controls. Users who require strict transport guarantees should configure them explicitly (for example, set `PROMPTFOO_INSECURE_SSL=false`, point `PROMPTFOO_CA_CERT_PATH` at a trusted bundle, or run Promptfoo behind a transport-enforcing egress proxy). Reports about relaxed or disabled certificate verification are out of scope when Promptfoo sends data only to a destination configured for that path and does not bypass a documented transport-security setting that the user has explicitly configured.
+
+Promptfoo-hosted features are configured for the documented payload of the feature the user invokes, enables, signs into, or uses through a Cloud-backed flow. Examples include remote test generation, remote grading, HTTP provider generation, red team target/provider setup helpers, red team target/provider test requests, sharing, Cloud sync, hosted report viewing, hosted scan upload, telemetry, account/license checks, update checks, and consent tracking. Hosted-feature payloads may include account identifiers, usage metadata, application purpose, config fields, prompts, vars, datasets, provider and model identifiers, provider configuration fields, request/response examples, target URLs, target request headers, bearer tokens or other auth material entered into red team target/provider setup/test forms, target and grader inputs or outputs, conversation history, traces, reports, scan artifacts, media or blob data, and derived artifacts needed to provide the selected feature.
+
+Logging into Promptfoo Cloud configures Promptfoo-operated account, license, consent, telemetry, Cloud sync, hosted storage, sharing, media/blob, and product-control endpoints for their documented purposes. A Cloud-backed feature should document whether it stores, shares, syncs, or transiently processes eval content. Reports about Cloud or hosted-feature data transfer are in scope only when Promptfoo sends data outside the documented payload or bypasses a documented control that applies to that hosted path.
+
+Remote generation, remote grading, Cloud sync, sharing, telemetry, and hosted scan or report features have different data requirements. Hosted test generation may receive the application purpose, plugin/strategy configuration, generated attack context, user email for usage tracking, and any additional data documented for the selected hosted strategy. Hosted multi-turn or agentic attack generation may receive conversation history or target responses when that data is required by the selected strategy and the user has not enabled a documented privacy control that applies to that path. Hosted grading may receive the prompt sent to the target, the target response, grading criteria, and related assertion context. Feature documentation should describe the data sent for each hosted path.
+
+**Supported hardening controls and opt-outs:**
+
+Documented opt-out and disable controls are operational controls for the feature families and data paths they describe. They are not sandbox, firewall, tenant-isolation, or general network-egress security boundaries. A path that does not honor a disable value is usually treated as a product correctness or privacy bug rather than a security-boundary bypass when the data is sent only to a configured provider, Promptfoo-operated endpoint, account endpoint, hosted feature, or Cloud-backed feature for that documented path.
+
+- `PROMPTFOO_DISABLE_TELEMETRY` disables product analytics and session replay within the documented telemetry system. Account, license, consent, update checks, sharing, Cloud sync, hosted report viewing, hosted scan upload, and hosted inference are separate features. Promptfoo may still send control-plane requests needed to authenticate the user, check license status, record consent or opt-out state, or operate an explicitly invoked hosted feature. The opt-out acknowledgment that records that telemetry was disabled may itself include the local user identifier and, when set, the email associated with the local Promptfoo environment, so that opt-out usage can be measured.
+- `PROMPTFOO_DISABLE_REMOTE_GENERATION` disables supported Promptfoo-hosted generation/inference fallbacks within its documented scope, including red team target/provider setup helpers that rely on remote generation. It is not a general network egress firewall and does not disable explicitly configured providers, graders, HTTP endpoints, sharing, Cloud sync, account/license requests, telemetry controls, red team target/provider test requests, red team target/provider setup helpers that do not rely on remote generation, or hosted features whose documentation states a separate control.
+- `PROMPTFOO_DISABLE_REDTEAM_REMOTE_GENERATION` disables supported Promptfoo-hosted red-team generation paths within its documented scope, including red team target/provider setup helpers that rely on remote generation. It leaves non-red-team hosted generation, red team target/provider test requests, red team target/provider setup helpers that do not rely on remote generation, sharing, telemetry, account, and Cloud-backed controls unchanged.
+- Sharing and Cloud-upload controls govern the upload paths described in their documentation. They do not disable local artifacts, explicitly requested share helpers, account/license requests, telemetry controls, or unrelated hosted features unless the documentation says they do.
+
+**Local artifacts and logs:**
+
+Promptfoo stores local artifacts such as logs, cache entries, databases, trace data, media blobs, config snapshots, reports, and exported files under the user's local account. These local artifacts are not external destinations by themselves. For OSS, secret persistence or display that remains confined to the same local user account is generally treated as a hardening or privacy issue rather than a security-boundary bypass. It becomes in scope only when Promptfoo bypasses a documented redaction, exclusion, authentication, authorization, or tenant-isolation control, or uploads, shares, exports, or otherwise exposes that data beyond the same local account, including to other users or tenants.
+
+Local caches, OAuth/token stores, provider response caches, temporary files, debug logs, report databases, and media/blob stores are scoped to the user's local Promptfoo environment. They are not isolation boundaries between different credentials, providers, endpoints, regions, tenants, accounts, evals, projects, or users running under the same local account unless Promptfoo documents such partitioning for a specific feature. Cache keys, token-store keys, and local artifact paths are not guaranteed to include provider identity, endpoint, region, tenant, account, credential, or project identity unless documented. Cache or token reuse, collision, overwrite, or lookup ambiguity within the same local user environment is generally treated as hardening or privacy behavior rather than a security-boundary bypass. Use separate operating-system users, containers, `PROMPTFOO_CONFIG_DIR` values, cache directories, token stores, and credentials when you need isolation between projects, tenants, or accounts.
+
+Shared or Cloud-backed reports may include the snapshot needed to view, reproduce, or inspect the result, including prompts, vars, outputs, traces, metadata, provider configuration fields, media/blob references, scan artifacts, and derived artifacts. Do not put secrets in prompts, datasets, provider config fields, metadata, or other shareable inputs unless that field is documented as redacted. If a field is documented as redacted or excluded, bypassing that redaction or exclusion is in scope.
+
+Report files, Markdown, HTML, CSV, JSON, screenshots, and other exports are generated artifacts from the user's run. They may contain active markup, formulas, links, media, `data:` URLs, or provider-controlled text. Treat exported artifacts as untrusted when opening them in browsers, spreadsheets, terminals, or other tools.
+
+### Contributor, CI, and Automation Tooling
+
+Promptfoo's public repository workflows, example CI snippets, code-scan action configuration, package-manager behavior, local agent/editor automation, and maintainer scripts are developer automation surfaces. They are not a product sandbox for untrusted pull requests, repository files, npm configuration, editor settings, or agent instructions.
+
+Treat pull-request content, repository-local config files, `package.json` scripts, npm configuration, workflow inputs, scanner guidance files, and agent/editor instructions as trusted code whenever a workflow or local automation runs them with secrets or write-capable credentials. Do not run Promptfoo, repository CI, scanners, agent tools, or examples with secrets on untrusted pull requests or third-party repositories unless those jobs are isolated and the credentials are scoped for that run.
+
+Reports about repository automation are generally out of scope unless they affect Promptfoo-published packages, released product behavior, Cloud/on-prem tenant isolation, or a documented product security boundary.
+
+## Hardening Recommendations
+
+If you run Promptfoo in higher-risk contexts (CI, shared machines, third-party configs or prompt packs, adversarial providers or models, model-output feedback loops):
+
+- Run inside a container or VM with minimal privileges
+- Use dedicated, least-privileged API keys
+- Avoid placing secrets in prompts, fixtures, or config files
+- Restrict network egress when running third-party code or adversarial eval content
+- Use separate `PROMPTFOO_CONFIG_DIR` values, cache directories, containers, or operating-system users when switching between accounts, tenants, or sensitive projects
+- Configure explicit TLS, proxy, and certificate-authority settings when your environment requires transport guarantees beyond Promptfoo defaults
+- In CI: do not run Promptfoo with secrets on untrusted PRs (e.g., from forks)
+- Do not expose local developer interfaces to untrusted networks or the public internet
+- If the host machine is reachable from other devices, bind local developer interfaces (web UI, MCP HTTP transport, helper servers) explicitly to a loopback address rather than relying on the default bind behavior
+- Use a reverse proxy with authentication if you need remote access to the web UI or MCP server
+- If you need cross-domain access to the local server, set `PROMPTFOO_CSRF_ALLOWED_ORIGINS` to a comma-separated list of trusted origins
+
+## Supported Versions
+
+| Version                               | Supported        |
+| ------------------------------------- | ---------------- |
+| Latest published release (npm/Docker) | ✅               |
+| `main` branch (unreleased fixes)      | ✅ (best effort) |
+| Previously published releases         | ❌               |
+
+We do not backport security fixes. Unsupported releases are previously published versions older than the latest published release. If you report an issue against an older release, we may ask you to reproduce it on the latest supported version.
+
+## Reporting a Vulnerability
+
+**Do not** open a public GitHub issue for security reports.
+
+Report privately via:
+
+- **GitHub Security Advisories:** [Report a vulnerability](https://github.com/promptfoo/promptfoo/security/advisories/new) (preferred — this is a secure channel)
+- **Email:** security@promptfoo.dev (fallback: support@promptfoo.dev)
+
+Email is not encrypted by default. For sensitive details (exploit code, PoC artifacts), use GitHub Security Advisories or wait until we establish a secure channel.
+
+We will acknowledge your report within **1 business day**.
+
+For safe harbor provisions and full process details, see our [Responsible Disclosure Policy](https://www.promptfoo.dev/responsible-disclosure-policy/).
+
+### What to Include in Your Report
+
+A good report helps us triage and fix issues faster. Please include:
+
+- **Description** of the vulnerability and its security impact
+- **Reproduction steps** — minimal config snippet or sequence of actions (redact any real secrets or API keys)
+- **Promptfoo version** (`promptfoo --version` or `promptfoo debug`)
+- **Environment** — Node.js version, OS, install method (npm, npx, Docker)
+- **Affected surface** — CLI, web UI, or library/SDK
+- **Model provider** in use, if relevant to the issue
+- **Whether you reproduced on the latest supported release** (or `main`) and, if not, why
+- **Exact code path** — relevant file/function/line range, if known
+- **For browser-origin claims:** a real browser-based PoC. Spoofed `Origin` or `Sec-Fetch-Site` headers from `curl` are not sufficient
+- **Why the issue exceeds the documented trust model** in this policy
+
+### Common Triage Outcomes
+
+We may close reports as one of the following:
+
+- **Invalid** — the reported behavior does not reproduce, depends on stale/nonexistent code, or relies on an unrealistic setup
+- **Out of scope** — the behavior matches the documented trust model or requires explicitly configured trusted code or eval content
+- **Duplicate** — the report is materially the same as an earlier advisory
+- **Already fixed** — the issue is valid but no longer affects the latest supported release
+
+## Response Timeline
+
+These are response targets, not service-level guarantees.
+
+- Acknowledgment and initial assessment are measured from report receipt.
+- Remediation targets start once we confirm severity.
+
+| Stage                    | Target           |
+| ------------------------ | ---------------- |
+| Acknowledgment           | 1 business day   |
+| Initial assessment       | 5 business days  |
+| Fix (Critical, 9.0–10.0) | 14 calendar days |
+| Fix (High, 7.0–8.9)      | 30 calendar days |
+| Fix (Medium, 4.0–6.9)    | 60 calendar days |
+| Fix (Low, 0.1–3.9)       | Best effort      |
+
+Severity is assessed using [CVSS v4.0](https://www.first.org/cvss/v4.0/specification-document), supplemented by Promptfoo's trust model and deployment context. Targets assume we have enough information to reproduce or validate the issue and are not blocked on reporter follow-up or upstream fixes. We may ship mitigations or workarounds before a full fix is available. We may adjust timelines if a fix requires significant architectural changes and **will communicate any material delays**.
+
+**Promptfoo-specific severity considerations (illustrative, not automatic):**
+
+- Code execution that bypasses a supported isolation boundary or hardening control: typically **Critical**
+- Secret or credential leakage to destinations not configured to participate in the selected eval, account, reporting, sharing, hosted-feature, or Cloud path: typically **High**
+- Bypasses of documented tenant-isolation, authentication, authorization, redaction, or exclusion controls that send data externally: typically **Medium–High**, depending on the data sent
+- Algorithmic DoS in CI pipelines causing significant resource exhaustion: typically **Medium–High**
+- Sensitive data written only to local logs, cache, token stores, traces, reports, exports, or databases: typically **Low–Medium**, and higher only if the artifact is uploaded, shared, or exposed to another user or tenant outside the documented sharing or Cloud-backed behavior
+- Web UI or report XSS requiring deliberate user interaction, local report access, or same-user artifact opening: typically **Low** or no CVE (see Scope)
+
+## Embargo and Non-Disclosure
+
+We ask reporters to keep vulnerability details confidential until:
+
+- A fix or mitigation is available, or
+- We agree on a disclosure date
+
+If remediation is delayed, we will keep the reporter informed and coordinate a revised disclosure timeline in good faith.
+
+## CVE Policy
+
+We request CVEs through GitHub Security Advisories when appropriate. Final advisory and CVE decisions depend on exploitability, impact, affected deployment model, and CNA policies and availability.
+
+**We usually request a CVE for:**
+
+- Code execution that bypasses a supported hardening control or isolation boundary outside the documented local eval pipeline
+- Bypasses of Cloud/on-prem isolation boundaries
+- Secret or credential leakage to destinations not configured to participate in the selected eval, account, reporting, sharing, hosted-feature, or Cloud path
+- Bypasses of documented tenant-isolation, authentication, authorization, redaction, or exclusion controls that send secrets, credentials, or sensitive eval data to an external destination
+- Supply chain compromise affecting Promptfoo-published packages, dependencies, or build artifacts
+
+**CVE-eligible (case-by-case):**
+
+- Algorithmic DoS in CI pipelines with significant resource impact
+- Sensitive data exposure through local artifacts when those artifacts are uploaded, shared, or exposed across users or tenants outside the documented sharing or Cloud-backed behavior
+- Web UI XSS with demonstrable impact beyond self-XSS
+
+**We generally do not request a CVE for:**
+
+- Issues in explicitly configured custom code or templates in code-executing fields (e.g., JS/Python assertions, custom providers, transforms, hooks, plugins)
+- Adversarial eval content flowing through the configured template engine and eval pipeline (e.g., model output interpolated into grading prompts, `_conversation` history rendered or passed through built-in assertions/graders, values saved with `storeOutputAs` reused as later eval inputs, variable or file-reference values dereferenced by configured eval steps, or data passed to configured providers)
+- Local API, local web UI, local MCP, CORS, CSRF, browser-origin, bind-address, or same-user local access issues within the documented trust model
+- Promptfoo-hosted feature requests, account/license/consent checks, telemetry controls, sharing, Cloud sync, hosted report viewing, hosted scan upload, or media/blob uploads that remain within the documented payload and controls for that feature
+- Sensitive data present only in local logs, cache, databases, traces, reports, screenshots, OAuth/token stores, temporary files, or exported files generated by the user's own run and confined to the same local user account, unless another supported boundary is crossed or the artifact is uploaded, shared, or exposed across users or tenants outside the documented sharing or Cloud-backed behavior
+- Local cache, provider response cache, OAuth/token-store, temporary-file, or artifact namespace reuse, collision, overwrite, or lookup ambiguity between credentials, providers, endpoints, regions, accounts, tenants, projects, or evals within the same local user environment, unless Promptfoo documents the namespace as an isolation boundary for that feature
+- TLS verification, certificate-validation, custom-CA, proxy, HTTP agent, or local network interception behavior for configured destinations, unless Promptfoo bypasses a documented transport-security control
+- Active content, formulas, links, media, or markup in local reports or exports generated from the user's eval data
+- File reads or writes outside the current project directory requested through trusted MCP tool arguments, local API requests, config values, or CLI options, unless a specific feature documents a hard workspace isolation boundary
+- Repository CI, examples, maintainer scripts, code-scan configuration, package-manager configuration, or local agent/editor automation unless the issue affects Promptfoo-published packages, released product behavior, Cloud/on-prem tenant isolation, or a documented product security boundary
+- Self-XSS requiring the user to paste payloads into their own console or UI
+- Quality, UX, or non-security functional bugs
+
+We may still fix issues in the categories above without requesting a CVE; this classification only affects whether we publish a formal advisory.
+
+## Safe Harbor
+
+We consider security research conducted in good faith to be authorized and will not initiate legal action against researchers who:
+
+- Act in good faith and follow this policy
+- Avoid privacy violations, data destruction, and service disruption
+- Do not access or modify other users' data
+- Report vulnerabilities promptly and do not exploit them beyond what is necessary to demonstrate the issue
+- Limit testing to Promptfoo-owned assets, or systems and accounts you own or are explicitly authorized to test (do not test third-party services, infrastructure, or other users' accounts)
+- Do not perform social engineering, phishing, physical attacks, or volumetric denial-of-service testing
+
+This safe harbor applies to activities conducted under this policy. For the full legal terms, see our [Responsible Disclosure Policy](https://www.promptfoo.dev/responsible-disclosure-policy/). In case of conflict, the Responsible Disclosure Policy governs.
+
+## Coordinated Disclosure
+
+When a fix is released, we will:
+
+1. Publish a [GitHub Security Advisory](https://github.com/promptfoo/promptfoo/security/advisories) with full details
+2. Credit the reporter by name (unless anonymity is requested)
+3. Document the fix in release notes or the CHANGELOG, as appropriate
+
+## Scope
+
+**In scope:**
+
+- Code execution, file access, network access, or secret exposure that bypasses a supported isolation boundary or hardening control outside the documented local eval pipeline
+- Bypasses of documented restrictions or isolation boundaries
+- Data, secret, or credential leakage to destinations not configured to participate in the selected eval, account, reporting, sharing, hosted-feature, or Cloud path, or outside the documented payload for that path
+- Path traversal or arbitrary file read/write that escapes a documented sandbox, authentication/authorization boundary, Cloud/on-prem tenant boundary, or explicit path restriction that Promptfoo identifies as a security boundary
+- Vulnerabilities in CLI, config parsing, or web UI affecting confidentiality, integrity, or availability beyond the intended trust model described above
+- Exposure of privileged local developer interfaces only when it bypasses an explicit authentication or authorization control documented for a remote or multi-user deployment
+- Bypasses of documented tenant-isolation, authentication, authorization, redaction, or exclusion controls
+- Sensitive local artifacts that are uploaded, shared, served to other users, or exposed across Cloud/on-prem tenant boundaries outside the documented sharing or Cloud-backed behavior
+- Algorithmic complexity DoS (crafted input causing hang/crash with modest input size)
+
+**Out of scope:**
+
+- Code execution from **explicitly configured** custom code or templates in code-executing fields (e.g., JS/Python assertions, custom providers, transforms, hooks, plugins, `file://`-backed scripts)
+- Adversarial eval content flowing through the configured template engine, variable loading or reference dereferencing, built-in assertions, graders, providers, transforms, reports, or model-output feedback loops. This includes model outputs, `_conversation` history, grader outputs, fixture values, values saved with `storeOutputAs`, and other stored runtime values later rendered, dereferenced, or passed through configured eval pipeline steps
+- Code execution caused by interpolating runtime data into a code-executing field the user configured, such as `value: 'output === "{{expected}}"'` in a JavaScript assertion — use `context.vars.expected` or safe serialization when the value should remain data
+- Code execution, data access, report access, CORS, CSRF, browser-origin, bind-address, local helper server, embedded client configuration, or network-reachability issues via **direct local web API access** or **browser access to the OSS local server** (e.g., `curl`, scripts, SDKs, the bundled UI, browser extensions, same-user local processes, another machine on the same network, or malicious webpages reaching `promptfoo view`) — the local server has the same trust level as the CLI and its CSRF/origin checks are best-effort hardening, not a supported security boundary
+- Direct access to the MCP server by a trusted local MCP client selected by the user, including tool behavior that is equivalent to running the CLI locally, unless a documented MCP authentication or authorization control is bypassed
+- File reads or writes outside the current project directory requested through trusted MCP tool arguments, local API requests, config values, or CLI options. Project roots and workspace paths are convenience defaults, not security boundaries, unless a specific feature documents a hard workspace isolation boundary
+- Issues requiring the user to run untrusted configs, scripts, prompt packs, fixtures, datasets, providers, models, remote content, or model-output feedback loops with local privileges, including cases where adversarial model output is rendered or processed by built-in assertions or graders during that local run
+- Network requests to URLs, providers, graders, Promptfoo-hosted features, account/license endpoints, telemetry controls, sharing endpoints, Cloud sync, hosted report viewing, hosted scan upload, media/blob upload, or other Promptfoo services that were configured to receive the relevant eval data, account data, artifacts, or credentials
+- Reports that treat telemetry, remote-generation, sharing, Cloud-upload, or privacy controls as a general network egress firewall outside the documented scope of the specific control
+- Reports that a disable flag or local-only preference was not honored when the request goes only to a configured provider, Promptfoo-operated endpoint, account endpoint, hosted feature, or Cloud-backed feature for the documented path. These are product correctness or privacy issues unless they bypass a documented tenant-isolation, authentication, authorization, redaction, or exclusion control
+- TLS, certificate-validation, proxy, or local network interception concerns for a user-configured destination when Promptfoo sends the data only along that configured path and does not bypass a documented transport-security setting
+- TLS verification, certificate-validation, custom-CA, proxy, HTTP agent, or local network interception behavior for Promptfoo-hosted feature requests that remain within the documented payload and controls for that feature, unless Promptfoo bypasses a documented transport-security control
+- Sensitive data present only in local logs, cache entries, OAuth/token stores, provider response caches, databases, trace files, temporary files, media blobs, screenshots, reports, or exports created by the user's own run and confined to the same local user account, unless a separate supported boundary is crossed, Promptfoo bypasses a documented redaction or exclusion control, or Promptfoo uploads, shares, or exposes that artifact beyond the documented local, sharing, or Cloud-backed behavior
+- Local cache, provider response cache, OAuth/token-store, temporary-file, or artifact namespace reuse, collision, overwrite, or lookup ambiguity between credentials, providers, endpoints, regions, accounts, tenants, projects, or evals within the same local user environment, unless Promptfoo documents the namespace as an isolation boundary for that feature
+- Active content, formulas, links, media, `data:` URLs, or markup in local reports, shared reports, screenshots, CSV/JSON exports, Markdown/HTML renderers, citations, or viewer downloads generated from the user's eval data
+- Shared or Cloud-backed report snapshots containing prompts, vars, outputs, traces, metadata, provider configuration fields, media/blob references, scan artifacts, or derived artifacts, unless Promptfoo bypasses a documented redaction or exclusion for that field
+- Repository workflows, example CI snippets, code-scan action configuration, package-manager behavior, local agent/editor automation, maintainer scripts, and other developer automation surfaces unless the issue affects Promptfoo-published packages, released product behavior, Cloud/on-prem tenant isolation, or a documented product security boundary
+- Reports based only on spoofed `Origin` or `Sec-Fetch-Site` headers from non-browser clients
+- Third-party dependency issues that don't materially affect Promptfoo's security posture (report upstream)
+- Social engineering, phishing, or physical attacks
+- Volumetric denial of service
+
+**Examples of out-of-scope reports:**
+
+- "A malicious custom assertion reads `process.env` and posts it to a webhook" → Expected behavior; custom code runs with your permissions
+- "A third-party prompt pack includes a transform that runs shell commands" → Expected behavior; don't run untrusted configs
+- "A third-party model returns template syntax that is rendered or processed by a built-in assertion or grader and appears in a grading prompt" → Expected behavior; the configured eval pipeline processes runtime data as part of normal operation. Run adversarial models with isolation and scoped credentials
+- "A model returns a `file://`-like value that is saved with `storeOutputAs` and reused as a later local eval variable" → Out of scope for OSS local eval security; model-output feedback loops can feed runtime data back through configured eval loading and rendering steps. Run adversarial models with isolation and scoped credentials
+- "An HTTP provider fetches a URL produced from a prompt or test variable" → Expected behavior; provider requests are part of the configured eval flow
+- "The local web API executes provider transforms as code" → Expected behavior; the web API has the same trust model as the CLI
+- "A trusted local MCP client asks Promptfoo to run an eval or inspect a config" → Expected behavior; MCP tools have the same trust model as local CLI invocations unless a documented MCP authentication or authorization control is bypassed
+- "An API key, bearer token, prompt, response, or config value appears in a local DB row, cache entry, report, export, or UI view generated by my own run" → Usually a hardening or privacy bug rather than a security-boundary bypass, unless Promptfoo bypassed a documented redaction or exclusion control or the artifact is uploaded, shared, or exposed beyond the documented local, sharing, or Cloud-backed behavior
+- "A malicious website can reach the local server if I replay browser headers with `curl`" → Not a valid browser repro, and local-server browser-origin claims are out of scope
+- "A browser DNS rebinding or `Host`/`Origin` confusion attack reaches the local web UI or MCP HTTP server" → Local deployment hardening; bind local interfaces explicitly to loopback when the host machine is reachable from other devices
+- "A non-browser client on the same network reaches a local API such as `/api/user/login`, `/providers/test`, `/providers/test-session`, or other helper endpoints because the bound port is reachable from other hosts" → Local deployment hardening; the local server has the same trust model as the CLI
+- "The local web UI or a provider helper page includes client configuration or API-key-bearing HTML and is reachable by another machine because I exposed the port" → Local deployment hardening; local helper pages have the same trust model as the CLI
+- "A trusted MCP client asks Promptfoo to write generated files outside the current project directory" → Expected behavior; MCP tool arguments and workspace paths are trusted local inputs unless a specific feature documents a hard workspace isolation boundary
+- "Two configured providers, endpoints, regions, accounts, or credentials can reuse or collide in a local cache or token store" → Expected local-environment behavior unless Promptfoo documents that cache or token namespace as an isolation boundary. Use separate config/cache directories or OS users when isolation is required
+- "A configured provider or hosted feature request uses Promptfoo's default TLS, proxy, certificate, or HTTP agent behavior" → Transport hardening concern, not a security-boundary bypass, unless Promptfoo bypassed a documented transport-security control
+- "A Promptfoo-hosted generation, red team target/provider setup/test, telemetry, sharing, or Cloud-backed path sends data despite a local-only or disable setting" → Product correctness or privacy issue, not a security-boundary bypass, when the request goes only to a configured provider or Promptfoo-operated hosted feature for that documented path
+- "A spreadsheet formula appears in a CSV export generated from my eval output" → Expected artifact behavior; treat exports as untrusted when opening them in other tools
+- "A signed-in Cloud workflow uploads a hosted report snapshot or scan artifact described by the feature documentation" → Expected Cloud-backed behavior
+- "A repository workflow, scanner, or local agent reads PR-controlled files while running with secrets" → Out of scope unless it affects Promptfoo-published packages, released product behavior, Cloud/on-prem tenant isolation, or a documented product security boundary
+
+If unsure whether something is in scope, report it anyway.

+Thank you for helping keep Promptfoo and its users safe.

+# Code Scan GitHub Action
+
+This package contains the GitHub Action wrapper for Promptfoo code scan.
+
+## Rules
+
+- Treat GitHub event fields, changed paths, `guidance`, and `guidance-file` contents as
+  untrusted. Pass PR-controlled values through `@actions/exec` argument arrays, not
+  shell interpolation.
+- Keep `github-token` out of package installs, scanner subprocesses, and PR-controlled
+  code. Preserve sanitized npm env handling, and keep fork-PR/OIDC fallback explicit.
+- Keep `action.yml`, `src/main.ts`, tests, `site/docs/code-scanning/github-action.md`,
+  and `code-scan-action/README.md` aligned when inputs or setup behavior change.
+- This directory has its own package and lockfile. Update them only for action
+  dependency changes, and add `dist/` only when packaging an action release.
+
+## Validation
+
+From the repo root:
+
+```bash
+npx vitest run test/code-scan-action
+npm --prefix code-scan-action run tsc
+npm --prefix code-scan-action run build
+```

+# Promptfoo Code Scan GitHub Action
+
+Automatically scan pull requests for LLM security vulnerabilities using AI-powered analysis.
+
+## About Code Scanning
+
+Promptfoo Code Scanning uses AI agents to find LLM-related vulnerabilities in your codebase and helps you fix them before you merge. By focusing specifically on LLM-related vulnerabilities, it finds issues that more general security scanners might miss.
+
+The scanner examines code changes for common LLM security risks including prompt injection, PII exposure, and excessive agency. Rather than just analyzing the surface-level diff, it traces data flows deep into your codebase to understand how user inputs reach LLM prompts, how outputs are used, and what capabilities your LLM has access to.
+
+After scanning, the action posts findings with severity levels and suggested fixes as PR review comments.
+
+To also surface findings in GitHub Code Scanning, configure `sarif-output-path` and upload the generated file with `github/codeql-action/upload-sarif`.
+
+## Quick Start
+
+**Recommended:** Install the [Promptfoo Scanner GitHub App](https://github.com/apps/promptfoo-scanner) for the easiest setup:
+
+1. Go to [github.com/apps/promptfoo-scanner](https://github.com/apps/promptfoo-scanner) and install the app
+2. Select which repositories to enable scanning for
+3. Submit your email or sign in (no account required—just a valid email address)
+4. Review and merge the setup PR that's automatically opened in your repository
+
+Once merged, the scanner will automatically run on future pull requests. Authentication is handled automatically with GitHub OIDC—no API key needed.
+
+**[Read the full documentation →](https://promptfoo.dev/docs/code-scanning/github-action)** for configuration options, manual installation, and more.
+
+## Fork Pull Requests
+
+Fork pull request scanning is disabled by default for `pull_request` workflows. A maintainer can trigger a fork PR scan through the Promptfoo Scanner comment flow, or you can opt in to scanning fork PRs automatically:
+
+```yaml
+- name: Run Promptfoo Code Scan
+  id: promptfoo-code-scan
+  uses: promptfoo/code-scan-action@v0
+  with:
+    enable-fork-prs: true
+```
+
+## SARIF Output
+
+Grant `security-events: write` in the workflow job permissions, then upload the generated file.
+The action sets `sarif-path` only when a scan actually completes, so keep the upload step conditional:
+
+```yaml
+- name: Run Promptfoo Code Scan
+  id: promptfoo-code-scan
+  uses: promptfoo/code-scan-action@v0
+  with:
+    sarif-output-path: promptfoo-code-scan.sarif
+
+- name: Upload SARIF to GitHub Code Scanning
+  if: ${{ steps.promptfoo-code-scan.outputs.sarif-path != '' }}
+  uses: github/codeql-action/upload-sarif@54f647b7e1bb85c95cddabcd46b0c578ec92bc1a # v4.36.3
+  with:
+    sarif_file: ${{ steps.promptfoo-code-scan.outputs.sarif-path }}
+    category: promptfoo-code-scan
+```
+
+## Supply Chain Security
+
+The hardening below applies to releases after v0.1.8; earlier releases resolve `promptfoo@latest` at runtime and predate the provenance attestation.
+
+- **Pinned scanner install.** The action installs an exact, release-pinned version of the `promptfoo` CLI with npm lifecycle scripts disabled (`--ignore-scripts`); it does not resolve `promptfoo@latest` at runtime. Use the `promptfoo-version` input (exact versions only) to override the pin.
+- **Pin by commit SHA for maximum assurance.** Version tags like `v0` and `v0.1.8` are managed by release automation and, like all git tags, are not cryptographically immutable — only a full commit SHA is. Resolve a release tag to its commit and pin that:
+
+  ```bash
+  gh api repos/promptfoo/code-scan-action/commits/<tag> --jq .sha
+  ```
+
+  ```yaml
+  uses: promptfoo/code-scan-action@<full-commit-sha> # <tag>
+  ```
+
+- **Verify build provenance.** The committed `dist/` bundle and the `action.yml` that selects the entrypoint are built and exported by the [promptfoo monorepo release workflow](https://github.com/promptfoo/promptfoo/blob/main/.github/workflows/release-please.yml), which publishes a signed build-provenance attestation for the exact artifact bytes. Verify a checkout of this repository with:
+
+  ```bash
+  gh attestation verify dist/index.js --repo promptfoo/promptfoo
+  gh attestation verify action.yml --repo promptfoo/promptfoo
+  ```
+
+  Additionally, every release PR in this repository is validated by a workflow that rebuilds `dist/` from the pinned monorepo source commit and fails on any byte difference.
+
+- **Don't run untrusted PR code before the scan in the same job.** The scanner install strips npm config and `NODE_OPTIONS` from its environment and isolates its npm config files, but a step that executes pull-request-controlled code earlier in the same job (for example `npm ci` or a build) can persist state — `$GITHUB_PATH`, `$GITHUB_ENV`, or `$HOME` writes — that later steps inherit, and such a step already runs with the job's token. Keep the scan in a job that only checks out the PR and scans it, or run untrusted build steps in a separate job.

+Guidance for AI agents editing the reusable docs in `docs/agents/`.
+
+## Rules
+
+- When changing PR workflow guidance, update both `docs/agents/pr-conventions.md` and
+  the root `AGENTS.md` "Pull Request Creation" section in the same PR.
+- When changing dependency workflow guidance, keep
+  `docs/agents/dependency-management.md` aligned with the root npm/audit guidance.
+- Do not introduce hard-coded local env-file requirements into generic eval commands.
+  Use `--env-file .env` only when credentials are needed and the file exists.
+- Do not claim that eval exit code 0 means all test cases passed unless the text
+  accounts for `PROMPTFOO_PASS_RATE_THRESHOLD`.
+- Verify implementation claims against source before documenting paths, defaults, or
+  environment variables, and avoid machine-specific paths.
+- Prefer concrete command examples over broad advice, and avoid duplicating long
+  guidance from root docs.
+
+## Validation

+# Codex App Server Provider Notes
+
+These notes track the planned Promptfoo integration for the Codex app-server protocol.
+They are intentionally implementation-facing: keep them current as the provider, docs,
+examples, and verification expand.
+
+For the broader coding-agent provider taxonomy, see
+[`coding-agent-provider-taxonomy.md`](./coding-agent-provider-taxonomy.md).
+
+## Objective
+
+Add an experimental Promptfoo provider that drives `codex app-server` directly. The
+provider should complement, not replace, the existing OpenAI Codex SDK provider:
+
+- Codex SDK provider: best default for CI and automation.
+- Codex app-server provider: best for evaluating rich-client behavior exposed by the
+  Codex app-server protocol, including streamed item events, approvals, skills,
+  plugins, apps, filesystem requests, and thread lifecycle primitives.
+
+Primary provider IDs:
+
+- `openai:codex-app-server`
+- `openai:codex-app-server:<model>`
+- `openai:codex-desktop`
+- `openai:codex-desktop:<model>`
+
+Optional top-level aliases may be added after the OpenAI-scoped provider is stable:
+
+- `codex:app-server`
+- `codex:desktop`
+
+## Source Material

+- Official docs: https://developers.openai.com/codex/app-server

+
+## Protocol Shape
+
+Transport:
+
+- `stdio://` default, JSONL messages.
+- `ws://IP:PORT` experimental, one JSON-RPC message per WebSocket text frame.
+
+Handshake:
+
+1. Send `initialize` with Promptfoo client metadata.
+2. Send `initialized` notification.
+3. Start or resume a thread.
+4. Start a turn.
+5. Read notifications until `turn/completed`.
+
+Core client requests:
+
+- `initialize`
+- `thread/start`
+- `thread/resume`
+- `thread/archive`
+- `thread/unsubscribe`
+- `thread/read`
+- `turn/start`
+- `turn/steer`
+- `turn/interrupt`
+- `review/start`
+- `model/list`
+- `skills/list`
+- `plugin/list`
+- `plugin/read`
+- `app/list`
+
+High-risk client requests that should not be exposed casually:
+
+- `fs/writeFile`
+- `fs/remove`
+- `fs/copy`
+- `config/value/write`
+- `config/batchWrite`
+- `plugin/install`
+- `plugin/uninstall`
+- `command/exec`
+
+Core server notifications:
+
+- `thread/started`
+- `thread/status/changed`
+- `turn/started`
+- `turn/completed`
+- `item/started`
+- `item/completed`
+- `item/agentMessage/delta`
+- `item/commandExecution/outputDelta`
+- `item/fileChange/outputDelta`
+- `item/mcpToolCall/progress`
+- `serverRequest/resolved`
+- `thread/tokenUsage/updated`
+- `error`
+
+Core server requests requiring deterministic Promptfoo responses:
+
+- `item/commandExecution/requestApproval`
+- `item/fileChange/requestApproval`
+- `item/permissions/requestApproval`
+- `item/tool/requestUserInput`
+- `mcpServer/elicitation/request`
+- `item/tool/call`
+
+## Provider Contract
+
+### Inputs
+
+Promptfoo prompt strings remain the default. The provider should also accept a JSON
+array of Codex input items:
+
+```json
+[
+  { "type": "text", "text": "Review this project" },
+  { "type": "local_image", "path": "/absolute/path/to/screenshot.png" },
+  { "type": "skill", "name": "skill-creator", "path": "/absolute/path/SKILL.md" }
+]
+```
+
+Supported input item types for the first implementation:
+
+- `text`
+- `local_image`, mapped to app-server `inputImage`
+- `skill`
+
+Unknown prompt JSON should be treated as plain text instead of throwing.
+
+### Output
+
+The provider response should include:
+
+- `output`: final assistant text, assembled from `item/agentMessage/delta` and
+  completed `agentMessage` items.
+- `sessionId`: thread id.
+- `raw`: serialized protocol-level turn summary and selected notifications.
+- `metadata.codexAppServer`: thread id, turn id, model, cwd, sandbox, approvals,
+  server requests, item counts, command/file/tool trajectories, and app-server
+  protocol data useful for debugging.
+- `metadata.skillCalls` / `metadata.attemptedSkillCalls`: heuristic skill usage
+  where available.
+- `tokenUsage`: from `thread/tokenUsage/updated` if emitted.
+- `cost`: estimated from Promptfoo's Codex pricing table when model is known.
+
+### Config
+
+Provider-level config should be strict. Prompt-level merged config should strip unknown
+keys so generic Promptfoo prompt config does not break rows.
+
+Core config:
+
+- `apiKey`
+- `base_url`
+- `working_dir`
+- `additional_directories`
+- `skip_git_repo_check`
+- `codex_path_override`
+- `model`
+- `model_provider`
+- `service_tier`
+- `sandbox_mode`
+- `sandbox_policy`
+- `approval_policy`
+- `approvals_reviewer`
+- `model_reasoning_effort`
+- `reasoning_summary`
+- `personality`
+- `output_schema`
+- `thread_id`
+- `persist_threads`
+- `thread_pool_size`
+- `ephemeral`
+- `persist_extended_history`
+- `experimental_raw_events`
+- `experimental_api`
+- `cli_config`
+- `cli_env`
+- `inherit_process_env`
+- `reuse_server`
+- `deep_tracing`
+- `request_timeout_ms`
+- `startup_timeout_ms`
+- `server_request_policy`
+
+### Safety Defaults
+
+Default stance should favor repeatable evals over convenience:
+
+- `approval_policy`: `never`
+- `sandbox_mode`: `read-only`
+- `network_access_enabled`: `false`
+- `ephemeral`: `true`
+- `reuse_server`: `true` unless `deep_tracing` is enabled
+- `inherit_process_env`: `false`
+- Server-side approval requests: decline/cancel or empty grants unless explicitly
+  configured.
+
+Rationale:
+
+- The app-server exposes shell, filesystem, app connector, plugin, and config surfaces.
+- Promptfoo evals should be deterministic and should not block on human approval.
+- Eval prompts and target behavior can be adversarial.
+
+## Implementation Phases
+
+1. Stdio JSON-RPC client
+   - Spawn `codex app-server`.
+   - Parse JSONL stdout.
+   - Route responses, notifications, and server requests.
+   - Capture stderr for debug logs.
+   - Support abort and timeout.
+
+2. Provider lifecycle
+   - Register with `providerRegistry`.
+   - Reuse app-server process by default.
+   - Shut down child processes, pending requests, and readline handles.
+   - Disable reuse when `deep_tracing` is enabled.
+
+3. Thread and turn execution
+   - Validate working directory.
+   - Start/resume threads.
+   - Start turns with prompt input, model, cwd, sandbox, approvals, effort, personality,
+     service tier, and output schema.
+   - Serialize turns per reused thread.
+   - Unsubscribe/archive non-persistent threads during cleanup.
+
+4. Streaming aggregation
+   - Track `turnId`.
+   - Assemble assistant deltas.
+   - Store completed items.
+   - Build item counts and trajectory metadata.
+   - Capture command output, file changes, MCP calls, dynamic tool calls, web search,
+     plans, reasoning summaries, and review output.
+
+5. Server request handling
+   - Deterministically answer command approvals.
+   - Deterministically answer file-change approvals.
+   - Return empty permission grants by default.
+   - Support configured answers for `tool/requestUserInput`.
+   - Decline/cancel MCP elicitation by default.
+   - Support static dynamic-tool responses.
+   - Record all requests and decisions in metadata.
+
+6. Tracing
+   - Wrap `callApi` in `withGenAISpan`.
+   - Add item-level spans when streaming notifications arrive.
+   - Sanitize command output, tool arguments, and message text before trace attributes.
+   - Inject OTEL env when `deep_tracing` is enabled.
+
+7. Docs and examples
+   - Add provider docs.
+   - Add provider index entry.
+   - Add examples for basic usage, read-only repo review, structured output, approval
+     handling, skills, and tracing.
+
+8. Verification
+   - Unit tests with mocked child process and mocked protocol frames.
+   - Registry tests for provider IDs and model-in-path parsing.
+   - Docs/examples lint where applicable.
+   - Local smoke config using a harmless prompt and `sandbox_mode: read-only` if
+     credentials/login are available.
+   - Final dogfood: run the new provider against the git diff and iterate on comments.
+
+## Progress Log
+
+### 2026-04-09
+
+- Added initial provider implementation at `src/providers/openai/codex-app-server.ts`.
+- Added provider IDs under the OpenAI registry:
+  - `openai:codex-app-server`
+  - `openai:codex-app-server:<model>`
+  - `openai:codex-desktop`
+  - `openai:codex-desktop:<model>`
+- Implemented stdio JSON-RPC lifecycle:
+  - spawn `codex app-server --listen stdio://`
+  - `initialize`
+  - `initialized`
+  - `thread/start`
+  - `thread/resume`
+  - `turn/start`
+  - notification handling through `turn/completed`
+  - `thread/unsubscribe`/`thread/archive` cleanup modes
+- Implemented safe config defaults:
+  - `approval_policy: never`
+  - `sandbox_mode: read-only`
+  - `ephemeral: true`
+  - `thread_cleanup: unsubscribe`
+  - process env isolation unless `inherit_process_env: true`
+- Implemented deterministic server request responses:
+  - command execution approvals default to `decline`
+  - file changes default to `decline`
+  - permission requests default to empty grants
+  - user input requests default to empty answers
+  - MCP elicitations default to `decline`
+  - dynamic tools can use static configured responses
+- Implemented output normalization:
+  - assistant delta aggregation
+  - completed `agentMessage` fallback/preference
+  - token usage from `thread/tokenUsage/updated`
+  - cost estimate for known Codex models
+  - metadata with item counts, items, server request decisions, thread/turn ids
+- Implemented provider-level GenAI tracing and item spans.
+- Added mocked protocol tests in `test/providers/openai-codex-app-server.test.ts`.
+- Added registry tests in `test/providers/index.test.ts`.
+- Verification so far:
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - `npx vitest run test/providers/index.test.ts -t "Codex app-server|Codex desktop" --sequence.shuffle=false`
+  - `npm run tsc -- --pretty false`
+- Expanded mocked protocol tests to cover:
+  - `thread/resume`
+  - structured prompt input normalization
+  - default `thread/unsubscribe` cleanup
+  - user input request policy
+  - dynamic tool static response policy
+  - metadata sanitization
+- Ran a real local smoke eval through `npm run local -- eval -c examples/openai-codex-app-server/promptfooconfig.yaml --no-cache -o /tmp/promptfoo-codex-app-server-example.json`.
+  - Result: pass.
+  - Provider returned Codex app-server `sessionId`, token usage, item counts, thread id,
+    turn id, and structured JSON output.
+- Ran docs build:
+  - `cd site && SKIP_OG_GENERATION=true npm run build`
+  - Result: pass.
+- First dogfood review through `examples/openai-codex-app-server/review-diff/promptfooconfig.yaml`
+  found four actionable provider issues:
+  - startup timeout could leak a spawned app-server and leave a rejected reusable
+    connection promise cached
+  - reused connections closed over the first turn's server request policy
+  - app-server exit during a turn could leave the eval waiting forever when no turn
+    timeout was configured
+  - `raw` response payload serialized unsanitized protocol items
+- Fixed the dogfood findings and added regression coverage:
+  - failed startup closes the process and a later call spawns a fresh process
+  - active turns store their effective config so prompt-level server request policies are
+    honored on reused servers
+  - connection exit resolves active turns with a provider error and removes the dead
+    connection from reuse maps
+  - `raw` now contains sanitized thread, turn, token usage, notifications, and item
+    metadata
+  - final output now uses the last completed `agentMessage`, which avoids concatenating
+    progress messages with final structured review output
+- Verification after fixes:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 13 provider tests.
+- Second dogfood review passed the Promptfoo eval and returned valid JSON, but still
+  reported two provider comments:
+  - legacy `execCommandApproval` / `applyPatchApproval` requests identify the active
+    thread with `conversationId` and expect legacy review decisions
+  - persistent thread-pool eviction deleted local handles without unsubscribing the
+    evicted loaded thread
+- Additional hardening from the second dogfood pass:
+  - stdio parser now buffers partial JSON-RPC lines and rejoins literal newlines inside
+    command-output strings as escaped newlines before parsing
+  - legacy approval requests now map prompt-level policy to `approved`,
+    `approved_for_session`, `denied`, and `abort`
+  - legacy server requests can find active turn state by `conversationId`
+  - evicted persistent cached threads now send `thread/unsubscribe` before being removed
+  - added regression coverage for literal-newline JSON-RPC notifications, legacy
+    approval requests, and persistent thread-pool eviction
+- Verification after second dogfood fixes:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 16 provider tests.
+- Third dogfood review passed transport/eval and reported two lifecycle comments:
+  - stale persistent thread handles remained after a reused app-server process exited
+  - JSON-RPC request timeout cleanup removed the pending request but left an abort
+    listener attached
+- Additional hardening from the third dogfood pass:
+  - connection close now removes cached thread handles owned by that connection key
+  - per-request timeout cleanup now removes abort listeners before rejecting
+  - added regression coverage for cached-thread invalidation after process exit and
+    abort-listener cleanup on JSON-RPC timeout
+- Verification after third dogfood fixes:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 18 provider tests.
+- Fourth dogfood review passed transport/eval and reported two thread-cache comments:
+  - persistent thread caching was still enabled for fresh-per-call app-server processes
+    (`reuse_server: false` or `deep_tracing`)
+  - pool eviction could unsubscribe an active cached thread before its turn completed
+- Additional hardening from the fourth dogfood pass:
+  - thread caching is now allowed only when the app-server connection itself is reusable
+  - active/reserved thread ids are protected with a small refcount while a call is using
+    them
+  - thread-pool eviction skips protected threads and temporarily allows the pool to
+    exceed its soft cap rather than evicting an in-flight turn
+  - added regression coverage for non-reusable persistent-thread configs and active-turn
+    eviction avoidance
+- Verification after fourth dogfood fixes:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 20 provider tests.
+- Fifth dogfood review passed transport/eval and reported one persistent-thread race:
+  - concurrent calls with the same persistent-thread cache key could both miss the cache
+    while the first `thread/start` was still pending, creating duplicate persistent
+    threads and leaking the earlier one
+- Additional hardening from the fifth dogfood pass:
+  - added an in-flight thread promise map keyed by thread cache key
+  - concurrent same-cache `thread/start` / `thread/resume` callers now share the same
+    pending thread handle
+  - added regression coverage for concurrent same-cache persistent calls, ensuring only
+    one `thread/start` is sent and both turns use the shared thread
+- Verification after fifth dogfood fix:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 21 provider tests.
+- Sixth dogfood review passed transport/eval and reported two cache/default comments:
+  - reusable connections could keep the first request timeout for requests that did not
+    pass a per-call timeout
+  - persistent thread cache keys omitted thread-start options such as `ephemeral`,
+    `experimental_raw_events`, and `persist_extended_history`
+- Additional hardening from the sixth dogfood pass:
+  - all provider-owned app-server requests now pass the effective per-call request
+    timeout explicitly
+  - persistent thread cache keys now include thread-start options that can change thread
+    semantics
+  - added regression coverage for prompt-level request timeouts on reused connections and
+    thread-start option changes in persistent cache keys
+- Verification after sixth dogfood fixes:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 23 provider tests.
+- Seventh dogfood retry:
+  - first attempt hit an external Codex connectivity failure (`Network is unreachable`,
+    `Reconnecting... 2/5`), which the provider surfaced as a clean provider error
+  - retry completed transport/eval and reported one metadata issue: skill-root detection
+    used the parent process env instead of the resolved app-server child env
+- Additional hardening from the seventh dogfood pass:
+  - turn state now carries the resolved app-server environment produced by
+    `prepareEnvironment`
+  - skill root detection now uses the child env for `CODEX_HOME`, `HOME`, and
+    `USERPROFILE`
+  - added regression coverage for `cli_env.HOME` skill-call metadata detection
+- Verification after seventh dogfood fix:
+  - `npm run tsc -- --pretty false`
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`
+  - Result: pass, 24 provider tests.
+- Eighth dogfood review:
+  - `npm run local -- eval -c examples/openai-codex-app-server/review-diff/promptfooconfig.yaml --no-cache --no-share -o /tmp/promptfoo-codex-app-server-review.json`
+  - Result: pass.
+  - Provider output: `{"comments":[],"summary":"No actionable findings; TypeScript and focused provider tests passed."}`
+  - This confirms the provider can be used to review the current git diff and return
+    schema-valid JSON with no remaining actionable comments from the dogfood reviewer.
+- Final verification sweep:
+  - `npm run f`: pass with existing complexity warnings only; no formatting changes needed
+  - `npm run tsc -- --pretty false`: pass
+  - `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`:
+    pass, 24 provider tests
+  - `npx vitest run test/providers/index.test.ts -t "Codex app-server|Codex desktop" --sequence.shuffle=false`:
+    pass, 2 registry tests
+  - `npm run l`: pass with existing complexity warnings only
+  - `cd site && SKIP_OG_GENERATION=true npm run build`: pass
+  - `npm run local -- eval -c examples/openai-codex-app-server/promptfooconfig.yaml --no-cache --no-share -o /tmp/promptfoo-codex-app-server-example.json`:
+    pass
+
+## QA Matrix
+
+Required mocked unit tests:
+
+- Constructor defaults and strict config validation.
+- Prompt-level unknown config stripping.
+- Missing/inaccessible/non-directory working directory.
+- Git check and `skip_git_repo_check`.
+- API key/env isolation and explicit `cli_env`.
+- Handshake order: `initialize`, `initialized`, `thread/start`, `turn/start`.
+- Model from provider path overrides/defaults correctly.
+- `thread_id` uses `thread/resume`.
+- `persist_threads` reuses cached thread and serializes turns.
+- Non-persistent calls unsubscribe/archive as configured.
+- Assistant deltas aggregate into final output.
+- Completed `agentMessage` fallback works when deltas are missing.
+- Token usage from `thread/tokenUsage/updated`.
+- Error notification produces provider error.
+- Failed turn produces provider error.
+- Abort before start.
+- Abort during turn sends `turn/interrupt` and returns aborted error.
+- Command approval request default decline.
+- File change request default decline.
+- Permission request default empty grant.
+- User input request configured answers.
+- Dynamic tool call configured static response.
+- MCP elicitation default decline/cancel.
+- Metadata contains item counts, trajectories, approvals, raw notifications, and server
+  request decisions without leaking API keys.
+- `cleanup` kills child process and unregisters provider.
+- `deep_tracing` injects OTEL env and disables reuse/thread persistence.
+- Provider-level GenAI tracing records response body, token usage, session id, and item
+  count attributes.
+
+Required docs/examples checks:
+
+- Provider docs render in Docusaurus.
+- Examples are listed and runnable from repo root with `npm run local -- eval ... --no-cache`.
+- Config docs call out experimental status, safety defaults, and difference from Codex SDK.
+
+## Open Questions
+
+- Whether to expose WebSocket transport in the first public version. Stdio is enough for
+  Promptfoo-managed app-server processes; WebSocket is useful for external clients but
+  adds auth and lifecycle complexity.
+- Whether to support top-level `codex:*` aliases immediately or keep all new IDs under
+  `openai:*` for consistency with the existing Codex SDK provider.
+- Whether to persist generated app-server protocol types in source. The current plan is
+  to implement a narrow local type surface and document how to regenerate schemas instead
+  of committing a large generated bundle.
+
+## Critical Audit Follow-up
+
+Review feedback and red-team audit items addressed after the initial dogfood pass:
+
+- Fixed registry env propagation for object-shaped provider configs. `loadApiProvider`
+  already merges suite-level and provider-level env into `providerOptions.env`; the
+  registry now passes that merged env to `OpenAICodexAppServerProvider`.
+- Fixed `service_tier` to match the generated app-server schema from `codex-cli 0.118.0`:
+  `fast` and `flex` only.
+- Reset the hoisted `spawn` mock implementation in `beforeEach` to satisfy `test/AGENTS.md`
+  mock isolation rules.
+- Regenerated app-server TypeScript and JSON Schema into
+  `/tmp/codex-app-server-schema-current.XVTCwL` during the audit and compared rare
+  app-server fields against the implementation.
+- Added coverage for schema-supported rare fields:
+  - `model_reasoning_effort: none`
+  - exact `personality` values: `none`, `friendly`, `pragmatic`
+  - granular approval policy objects
+  - app-server command approval amendment objects
+  - session-scoped permission grants
+  - accepted MCP elicitation responses with content and metadata
+  - `base_instructions`, `developer_instructions`, and `collaboration_mode`
+- Dogfood review then found additional issues:
+  - reusable app-server connections stayed alive after JSON-RPC request timeouts, which
+    could leave late side-effecting responses unmanaged
+  - docs listed `thread_pool_size` as unlimited even though the implementation defaults
+    to `1`
+  - provider cleanup cleared active turns before resolving them, which could hang
+    shutdown while a turn was in flight
+  - raw JSON-RPC notifications were retained even when `include_raw_events` was false
+  - spawned app-server processes could be missed if cleanup ran while `initialize` was
+    still pending
+  - concurrent persistent thread starts could temporarily exceed `thread_pool_size` and
+    remain over capacity after active turns finished
+  - deep-tracing calls that shared a `thread_id` could overlap turns because the queue key
+    returned early
+  - the OpenAI provider docs heading change would have broken the existing `#codex-sdk`
+    anchor
+  - default `thread_id` resumes skipped unsubscribe cleanup
+  - sent JSON-RPC request aborts kept the reusable app-server alive
+  - retryable app-server `error` notifications with `willRetry: true` were treated as
+    terminal
+  - concurrent default-cleanup `thread_id` rows could unsubscribe while another row was
+    queued for the same thread
+- Fixed these by closing/evicting connections on timeout and abort, resolving active
+  turns during cleanup, tracking pending initialization processes, making raw event
+  retention opt-in, rebalancing the persistent thread pool after turns finish, serializing
+  explicit `thread_id` turns even under deep tracing, preserving the OpenAI docs
+  `#codex-sdk` heading, default-unsubscribing non-persistent resumed threads, honoring
+  retryable app-server errors, and deferring resumed-thread unsubscribe until no other
+  protected queued caller remains.
+- Updated docs to explain why the app-server provider should stay separate from the
+  Codex SDK provider: the SDK is the right default for CI and automation, while app-server
+  is for rich-client protocol event surfaces and does not attach to a running Codex
+  Desktop app.
+
+Latest focused verification after these fixes:
+
+- `npx vitest run test/providers/openai-codex-app-server.test.ts --sequence.shuffle=false`:
+  pass, 35 provider tests.
+- `npm run local -- eval -c examples/openai-codex-app-server/review-diff/promptfooconfig.yaml --no-cache --no-share`:
+  pass with `{"comments":[],"summary":"No actionable issues found in the current diff."}`.

+# Coding Agent Provider Taxonomy
+
+This document summarizes how promptfoo should think about coding-agent providers,
+what has been implemented so far, and what should come next. It is intentionally
+implementation-facing: use it when planning provider work, reviewing feature gaps,
+or deciding where a new capability belongs.
+
+## Scope
+
+This taxonomy covers providers that run an agentic coding runtime, not ordinary
+single-turn model APIs. A coding-agent provider usually has some combination of:
+
+- A workspace or project directory.
+- Tool use for files, shell commands, MCP, search, or app connectors.
+- A session, thread, or server lifecycle.
+- Permission, sandbox, or approval controls.
+- Rich metadata beyond final assistant text.
+
+The main providers in this family today are:
+
+| Provider family         | Provider IDs                                          | Runtime boundary                           |
+| ----------------------- | ----------------------------------------------------- | ------------------------------------------ |
+| OpenAI Codex SDK        | `openai:codex-sdk`, `openai:codex`                    | `@openai/codex-sdk` library                |
+| OpenAI Codex app-server | `openai:codex-app-server`, `openai:codex-desktop`     | Local `codex app-server` JSON-RPC process  |
+| Claude Agent SDK        | `anthropic:claude-agent-sdk`, `anthropic:claude-code` | `@anthropic-ai/claude-agent-sdk` library   |
+| OpenCode SDK            | `opencode:sdk`, `opencode`                            | OpenCode SDK plus local or existing server |
+
+Standard OpenAI, Anthropic, Bedrock, Azure, and other model providers still matter
+for grading and comparison, but they are outside this taxonomy unless they expose a
+stateful coding-agent runtime.
+
+## Taxonomy Axes
+
+### 1. Runtime Boundary
+
+The first question is where promptfoo stops and the agent runtime starts.
+
+| Boundary                 | Meaning                                                       | Current examples                         |
+| ------------------------ | ------------------------------------------------------------- | ---------------------------------------- |
+| In-process SDK           | promptfoo calls a package API directly.                       | Codex SDK, Claude Agent SDK              |
+| Managed local server     | promptfoo starts a server, then talks to it through a client. | OpenCode when `baseUrl` is unset         |
+| Existing server          | promptfoo connects to a runtime it does not configure.        | OpenCode with `baseUrl`                  |
+| Local app-server process | promptfoo starts a rich-client protocol server over stdio.    | Codex app-server                         |
+| Desktop UI process       | Human-facing native app process.                              | Codex Desktop app, not directly attached |
+
+This distinction matters because it controls what promptfoo can guarantee. If
+promptfoo starts the runtime, it can set env vars, working directories, sandbox
+options, tracing, and cleanup behavior. If promptfoo attaches to an existing server,
+that server owns authentication, installed tools, app connectors, and runtime state.
+
+### 2. Session and Thread State
+
+Coding agents are rarely stateless. Each provider needs explicit semantics for:
+
+- Ephemeral sessions: safe default for independent eval rows.
+- Persistent sessions: useful for memory, multi-turn tasks, or regression suites.
+- User-supplied sessions: resume an existing thread/session by id.
+- Pooling: preserve concurrency without cross-contaminating rows.
+- Cleanup: unsubscribe, archive, delete temporary directories, or leave state alone.
+
+The important design rule is that session reuse must be opt-in or very clearly
+scoped. Reusing state silently makes eval results order-dependent.
+
+### 3. Workspace and Side Effects
+
+Agent evals should separate filesystem access, network access, and shell access.
+Those are different risks.
+
+| Surface     | Safe default                               | Higher-risk mode                                        |
+| ----------- | ------------------------------------------ | ------------------------------------------------------- |
+| Filesystem  | Temporary directory or read-only workspace | Workspace write or full filesystem access               |
+| Shell       | Disabled or approval-gated                 | Allowed command execution                               |
+| Network     | Disabled unless explicitly requested       | Host allow-lists, live web/search, package installs     |
+| App/plugin  | Not installed or not invoked by default    | App connectors, plugin installs, config writes          |
+| Environment | Minimal env                                | Inherited process env with secrets and local auth state |
+
+Provider docs should make clear that `danger-full-access` is not the same as
+network access, and read-only filesystem mode does not automatically sanitize env
+vars. Each surface should have its own option and its own tests.
+
+### 4. Permission and Interaction Model
+
+Promptfoo evals are non-interactive by default. Agent runtimes often expect a human
+to answer approval prompts, permission requests, or clarification questions.
+Providers should convert those into deterministic policies.
+
+Common policy categories:
+
+- Command approval.
+- File-change approval.
+- Permission grants.
+- User-input or ask-user-question tools.
+- MCP elicitation.
+- Dynamic tool calls.
+- Plugin or app connector requests.
+
+Default policy should decline, cancel, or return empty answers unless a config opts
+into side effects. Every accepted side effect should be visible in metadata.
+
+### 5. Inputs
+
+The baseline input is a prompt string. Coding-agent providers increasingly need
+structured inputs:
+
+- Text items.
+- Local images or image URLs.
+- Skills or plugin references.
+- Mentions/app connector references.
+- File, diff, or workspace context.
+
+Provider-specific JSON input arrays are acceptable when the underlying runtime has
+typed input items. Unknown JSON shapes should usually degrade to plain text rather
+than crashing an eval row, unless the provider docs promise strict input parsing.
+
+### 6. Outputs and Metadata
+
+All coding-agent providers should return a normal promptfoo provider result:
+
+- `output`: final assistant-facing text.
+- `sessionId`: session/thread id when available.
+- `tokenUsage`: runtime usage when available.
+- `cost`: estimate when usage and model pricing are known.
+- `metadata`: normalized agent metadata.
+- `raw`: raw or summarized protocol data when useful and safe.
+
+Provider-specific metadata is still valuable, but consumers need a shared shape for
+cross-provider assertions and dashboards. A future shared schema should include:
+
+- Runtime family and version.
+- Workspace and sandbox settings.
+- Session/thread/turn identifiers.
+- Tool trajectories.
+- Approval decisions.
+- File changes and command executions.
+- MCP and dynamic tool calls.
+- Skill/plugin/app connector usage.
+- Trace ids and span links.
+
+### 7. Observability
+
+Tracing should answer two questions:
+
+- What did the model decide?
+- What did the agent runtime do?
+
+Provider tracing should include the top-level `callApi` span, item/tool-level spans
+where possible, and sanitized attributes for prompts, commands, tool inputs, file
+paths, and outputs. Deep tracing should be opt-in when it requires injecting
+OpenTelemetry env vars into a child process.
+
+## What Is Implemented So Far
+
+### Shared Building Blocks
+
+The coding-agent providers already share several practical patterns:
+
+- Optional dependencies are loaded lazily so normal promptfoo installs do not need
+  every agent SDK.
+- Working directories are validated or created before the agent call.
+- Temporary workspaces are cleaned up after evals.
+- Session or thread caches are keyed by provider config.
+- Provider-level config is stricter than prompt-level merged config.
+- Tool and skill usage are surfaced through metadata where possible.
+- Tracing is supported for Codex and is partially shared through OpenAI agent
+  tracing helpers.
+
+Useful files:
+
+- `src/providers/agentic-utils.ts`
+- `src/providers/claude-agent-sdk.ts`
+- `src/providers/opencode-sdk.ts`
+- `src/providers/openai/codex-sdk.ts`
+- `src/providers/openai/codex-app-server.ts`
+- `src/providers/registry.ts`
+
+### OpenAI Codex SDK
+
+Status: implemented and documented.
+
+Provider IDs:
+
+- `openai:codex-sdk`
+- `openai:codex-sdk:<model>`
+- `openai:codex`
+- `openai:codex:<model>`
+
+Implemented capabilities:
+
+- Lazy loading for `@openai/codex-sdk`.
+- API-key and local Codex login authentication paths.
+- Working directory and Git repository safety checks.
+- Sandbox, network, web search, approval, and reasoning controls.
+- Thread resume and persistent thread pooling.
+- JSON schema output.
+- Text and local-image input items.
+- Skill usage heuristics from `SKILL.md` reads.
+- Token usage and cost estimation for known Codex models.
+- Streaming aggregation for metadata and tracing.
+- Deep tracing into the Codex runtime.
+- Default-provider support for grading when Codex credentials are available.
+
+Important limits:
+
+- It is the right default for CI and automation, but it does not expose every rich
+  app-server protocol event.
+- Skill detection is heuristic.
+- Promptfoo still receives a final provider response, not live partial output in
+  assertions.
+
+Docs and examples:
+
+- `site/docs/providers/openai-codex-sdk.md`
+- `examples/openai-codex-sdk/`
+
+### OpenAI Codex App Server
+
+Status: implemented, documented, and validated with mocked protocol tests plus a
+real local eval.
+
+Provider IDs:
+
+- `openai:codex-app-server`
+- `openai:codex-app-server:<model>`
+- `openai:codex-desktop`
+- `openai:codex-desktop:<model>`
+
+Implemented capabilities:
+
+- Spawns `codex app-server --listen stdio://`.
+- Drives the app-server JSON-RPC handshake.
+- Starts, resumes, unsubscribes, and archives threads according to config.
+- Starts turns with model, cwd, sandbox, approval, reasoning, personality,
+  collaboration mode, service tier, output schema, and instructions.
+- Accepts plain text plus JSON arrays of app-server input items.
+- Aggregates streamed item notifications into final text and metadata.
+- Captures item counts, command/file/MCP/tool/web-search/reasoning trajectories.
+- Handles server requests deterministically through `server_request_policy`.
+- Uses safe defaults: read-only sandbox, no approvals, ephemeral threads, minimal env.
+- Supports thread pooling and persistent thread cache invalidation.
+- Supports raw events, token usage, cost estimation, request timeouts, turn timeouts,
+  cleanup, aborts, and process failure handling.
+- Supports deep tracing by creating a fresh app-server process per row and injecting
+  OpenTelemetry env vars.
+- Differentiates the app-server protocol from the Codex Desktop app: promptfoo
+  starts its own app-server child process and does not attach to a running Desktop
+  app UI process.
+
+Important limits:
+
+- WebSocket transport is not implemented; stdio is the supported transport.
+- Live partial output is not exposed to assertions.
+- Direct attachment to a running Codex Desktop app is not implemented.
+- High-risk protocol requests such as config writes, plugin installs, and arbitrary
+  filesystem writes should remain unavailable or explicitly policy-gated.
+
+Docs and examples:
+
+- `site/docs/providers/openai-codex-app-server.md`
+- `docs/agents/codex-app-server-provider-notes.md`

+
+### Claude Agent SDK
+
+Status: implemented and documented.
+
+Provider IDs:
+
+- `anthropic:claude-agent-sdk`
+- `anthropic:claude-code`
+
+Implemented capabilities:
+
+- Lazy loading for `@anthropic-ai/claude-agent-sdk`.
+- Anthropic API key, Bedrock, Vertex, and local Claude Code auth flows.
+- Temporary or configured working directories.
+- Built-in tool controls, allowed/disallowed tools, and permission modes.
+- Explicit unsafe permission skip flag.
+- MCP server configuration and optional MCP caching.
+- AskUserQuestion handling.
+- Plugin and local skill support.
+- Custom agents, hooks, system prompt overrides, betas, thinking, and effort options.
+- Session resume, fork, continue, persistence, and file checkpointing options.
+- Sandbox and executable configuration.
+- Usage/cost controls such as max budget.
+
+Important limits:
+
+- The SDK owns many semantics, so promptfoo must keep docs aligned with SDK changes.
+- Side-effectful modes require external workspace reset discipline.
+
+Docs and examples:
+
+- `site/docs/providers/claude-agent-sdk.md`
+- `examples/claude-agent-sdk/`
+
+### OpenCode SDK
+
+Status: implemented and documented.
+
+Provider IDs:
+
+- `opencode:sdk`
+- `opencode`
+
+Implemented capabilities:
+
+- Lazy loading for `@opencode-ai/sdk` v1 or v2.
+- Starts an OpenCode server when `baseUrl` is unset.
+- Connects to an existing OpenCode server when `baseUrl` is provided.
+- Supports provider/model selection, variants, workspaces, and custom agents.
+- Supports temporary or configured working directories.
+- Uses read-only default tools for configured workspaces.
+- Supports write/edit/bash tools with explicit permission config.
+- Supports JSON Schema structured output through OpenCode `format`.
+- Supports sessions and persistent session caching.
+- Supports MCP configuration and optional MCP caching when promptfoo starts the
+  server.
+
+Important limits:
+
+- When using `baseUrl`, the existing server owns auth, MCP setup, installed agents,
+  and server-side configuration.
+- OpenCode model support is delegated to OpenCode/models.dev rather than promptfoo's
+  normal provider model tables.
+
+Docs and examples:
+
+- `site/docs/providers/opencode-sdk.md`
+- `examples/provider-opencode-sdk/`
+
+## Current Naming Guidance
+
+Use provider IDs that encode the runtime boundary, not just the model vendor.
+
+- `openai:codex` should continue to mean the Codex SDK alias because that is the
+  best default for automation.
+- `openai:codex-app-server` should mean the app-server JSON-RPC protocol.
+- `openai:codex-desktop` should remain an alias for app-server behavior unless or
+  until promptfoo can actually attach to the Desktop app process.
+- `anthropic:claude-code` should remain an alias for Claude Agent SDK because the
+  SDK is still built on Claude Code.
+- `opencode` can remain a convenience alias for `opencode:sdk`.
+
+Avoid adding unscoped top-level aliases such as `codex:desktop` until the OpenAI
+scoped names are stable and the docs can clearly explain the difference between
+SDK, app-server, and Desktop UI attachment.
+
+## What To Implement Next
+
+### 1. Shared Agent Metadata Schema
+
+Create a cross-provider `metadata.agent` shape while preserving provider-specific
+metadata namespaces such as `metadata.codexAppServer`.
+
+Proposed fields:
+
+- `runtime`: `codex-sdk`, `codex-app-server`, `claude-agent-sdk`, `opencode`.
+- `runtimeVersion`: runtime-reported version when available.
+- `sessionId`, `threadId`, `turnId`.
+- `workingDir`, `sandbox`, `network`, `approvalPolicy`.
+- `tools`: normalized tool calls and outcomes.
+- `commands`: normalized shell command executions.
+- `fileChanges`: normalized file write/edit/delete attempts.
+- `approvals`: normalized approval prompts and decisions.
+- `mcp`: normalized MCP calls and elicitations.
+- `skills`: confirmed and attempted skill usage.
+- `trace`: trace ids and span ids when available.
+
+Acceptance criteria:
+
+- Existing provider-specific metadata remains backward compatible.
+- Cross-provider assertions can target the same metadata path.
+- Tests cover at least Codex SDK, Codex app-server, Claude Agent SDK, and OpenCode.
+
+### 2. Shared Coding-Agent Provider Test Contract
+
+Add a reusable test contract for coding-agent providers. Each provider can implement
+the same scenarios with its own mocked runtime.
+
+Core scenarios:
+
+- Missing optional dependency.
+- API key/env precedence.
+- Working directory validation.
+- Prompt-level config merge.
+- Safe default sandbox and permissions.
+- Structured output.
+- Session persistence and cleanup.
+- Timeout and abort.
+- Runtime process/server failure.
+- Tool approval decline by default.
+- Metadata normalization.
+- Trace sanitization.
+
+Acceptance criteria:
+
+- New providers cannot skip lifecycle and safety cases.
+- Mock implementations reset hoisted mocks in `beforeEach`.
+- Concurrency tests prove one session/process failure cannot fail unrelated rows.
+
+### 3. Provider Capability Matrix
+
+Add a docs page or generated table that compares coding-agent provider capabilities.
+
+Suggested columns:
+
+- Provider IDs.
+- Runtime boundary.
+- Optional dependency or CLI requirement.
+- Auth modes.
+- Workspace model.
+- Sandbox controls.
+- Shell/file/network controls.
+- MCP support.
+- Skills/plugins/custom agents.
+- Structured output.
+- Session persistence.
+- Tracing.
+- Raw protocol metadata.
+- Existing-server attachment.
+
+Acceptance criteria:
+
+- The matrix links to each provider doc.
+- It clearly says that Codex Desktop attachment is not currently supported.
+- It is tested in the docs build.
+
+### 4. Real Eval QA Matrix
+
+Create a small set of real eval examples that can be run selectively by maintainers.
+
+Minimum scenarios:
+
+- Read-only repo review.
+- Structured JSON output.
+- Sandbox denial for attempted writes.
+- Workspace-write side effect in a disposable fixture.
+- Session persistence across two rows.
+- Skill or plugin invocation.
+- MCP tool call with a deterministic local MCP server.
+- Deep tracing smoke test.
+
+Acceptance criteria:
+
+- Each scenario records expected pass/fail/error behavior.
+- Each scenario can run with `--no-cache`.
+- Side-effectful scenarios use disposable workspaces.
+- CI can run a lightweight subset without requiring every optional agent runtime.
+
+### 5. Security and Redteam Coverage
+
+Add adversarial tests for the risky parts of agent runtimes.
+
+High-value cases:
+
+- Prompt injection that asks the agent to reveal env vars.
+- Path traversal through input items, tool args, or MCP responses.
+- Approval bypass attempts.
+- Plugin install/config-write attempts.
+- Network enablement attempts when network should be off.
+- Symlink writes out of the workspace.
+- Malicious `SKILL.md` or plugin instructions.
+- Tool output containing secrets that must be redacted from traces.
+
+Acceptance criteria:
+
+- Providers decline or isolate side effects by default.
+- Redaction is tested for command output, MCP arguments, tool arguments, prompts,
+  and final metadata.
+- Any accepted dangerous operation requires explicit config and is visible in
+  metadata.
+
+### 6. Codex App Server Follow-Up Features
+
+The app-server provider now covers the core eval path. The next app-server-specific
+work should focus on rare protocol features and product integration boundaries.
+
+Candidates:
+
+- `model/list`, `skills/list`, `plugin/list`, `plugin/read`, and `app/list`
+  metadata discovery.
+- `review/start` support for native review flows.
+- `turn/steer` and `turn/interrupt` tests for cancellation and mid-turn control.
+- Optional WebSocket transport only if upstream stabilizes it.
+- Better raw event snapshots for protocol regression tests.
+- Stronger docs around Desktop alias semantics and why promptfoo starts a separate
+  app-server process.
+
+Acceptance criteria:
+
+- Rare features are opt-in and deterministic.
+- High-risk operations are policy-gated.
+- Protocol additions have mocked tests and at least one documented example when
+  user-facing.
+
+### 7. Side-Effect Harness
+
+Build a reusable harness for tests and examples that need write access.
+
+It should provide:
+
+- Disposable workspace creation.
+- Git repository initialization when needed.
+- Snapshot before and after agent runs.
+- Symlink and path traversal fixtures.
+- Cleanup guarantees.
+- Helpers for expected file diffs.
+
+Acceptance criteria:
+
+- No side-effectful provider test mutates the source checkout.
+- Tests can assert exact changed files.
+- Harness works on macOS, Linux, and Windows CI.
+
+### 8. Documentation Cleanup
+
+Improve the information architecture around coding-agent providers.
+
+Recommended docs:
+
+- A public provider comparison matrix.
+- A "Choosing a coding-agent provider" guide.
+- A "Managing side effects in agent evals" guide.
+- Provider-specific "SDK vs app-server vs Desktop app" sections for Codex.
+- Example READMEs that all share the same run, auth, and safety structure.
+
+Acceptance criteria:
+
+- The public docs answer which provider to use for CI, Desktop-like protocol evals,
+  Claude Code compatibility, and OpenCode multi-provider setups.
+- Example configs validate locally.
+- Docs state safe defaults and side-effect responsibilities near every write-capable
+  example.
+
+## Review Checklist For New Coding-Agent Provider Work
+
+Before merging a provider in this family, verify:
+
+- Provider IDs are explicit about runtime boundary.
+- Optional dependencies fail with actionable install guidance.
+- API keys and local-auth modes are documented.
+- Env precedence is tested.
+- Working directory, sandbox, network, and shell controls are documented and tested.
+- Prompt-level config merges do not drop nested provider defaults.
+- Hoisted mocks with implementations reset in `beforeEach`.
+- Session/thread reuse is opt-in or explicitly scoped.
+- Runtime failures do not poison unrelated sessions or rows.
+- Approval/user-input/MCP requests have deterministic non-interactive defaults.
+- Metadata includes session ids, tool/command/file activity, and approval decisions.
+- Trace attributes are sanitized.
+- Examples validate and at least one real eval has been run when the runtime is
+  locally available.
+
+## Open Questions
+
+- Should promptfoo expose one public `metadata.agent` schema now, or keep it internal
+  until at least two providers use it in docs examples?
+- Should Codex app-server discovery operations be exposed as provider metadata on
+  every call, or only behind an explicit config flag?
+- Should any provider support a hard "no side effects" verifier that snapshots the
+  workspace and fails if files changed?
+- Should remote/existing-server modes be marked as less reproducible in promptfoo
+  output metadata?
+- Should top-level aliases like `codex:app-server` wait for a broader provider naming
+  cleanup?

+# Database Security (SQL Injection Prevention)
+
+This codebase uses Drizzle ORM with SQLite. All database queries must use parameterized SQL so user-controlled input never changes query structure.
+
+## Quick Rules
+
+- Use Drizzle's `sql` tagged template literals for dynamic values.
+- Use `sql.join()` for dynamic lists such as `IN (...)` clauses.
+- Pass `SQL<unknown>` fragments between functions, not strings.
+- Do not build queries with `sql.raw()` or string interpolation.
+- Prefer `json_each()` for user-selected JSON keys. When `json_extract()` is appropriate, bind a path built with the vetted `buildSafeJsonPath` helper in `src/models/eval.ts`.
+
+## Required Pattern: Use `sql` Template Strings
+
+Use parameterized queries for single values:
+
+```typescript
+import { sql } from 'drizzle-orm';
+
+const query = sql`SELECT * FROM eval_results WHERE eval_id = ${evalId}`;
+```
+
+Use parameterized queries for multiple values:
+
+```typescript
+import { sql } from 'drizzle-orm';
+
+const query = sql`
+  SELECT * FROM eval_results
+  WHERE eval_id = ${evalId} AND success = ${1}
+`;
+```
+
+Use `sql.join()` for dynamic `IN (...)` lists:
+
+```typescript
+import { sql } from 'drizzle-orm';
+
+const ids = ['id1', 'id2', 'id3'];
+const query = sql`SELECT * FROM evals WHERE id IN (${sql.join(ids, sql`, `)})`;
+```
+
+## Forbidden Pattern: Raw SQL with Dynamic Content
+
+Do not interpolate user-controlled values into raw SQL:
+
+```typescript
+const query = sql.raw(`SELECT * FROM eval_results WHERE eval_id = '${evalId}'`);
+```
+
+Do not build SQL conditions with string concatenation:
+
+```typescript
+import { sql } from 'drizzle-orm';
+
+const whereClause = `eval_id = '${evalId}'`;
+const query = sql.raw(`SELECT * FROM eval_results WHERE ${whereClause}`);
+```
+
+## JSON Paths in SQLite
+
+SQLite's `json_extract()` accepts its JSON path as a bound value. Do not use `sql.raw()` to splice user-controlled JSON paths into SQL. Prefer `json_each()` when filtering by dynamic keys, because the key can be compared as a normal parameter:
+
+```typescript
+import { sql } from 'drizzle-orm';
+
+const query = sql`
+  SELECT *
+  FROM eval_results
+  WHERE EXISTS (
+    SELECT 1
+    FROM json_each(metadata)
+    WHERE json_each.key = ${field} AND json_each.value = ${value}
+  )
+`;
+```
+
+If you construct a JSON path for `json_extract()`, use `buildSafeJsonPath` from `src/models/eval.ts`, which escapes backslashes and double quotes for JSON path syntax and returns a value to bind:
+
+```typescript
+import { sql } from 'drizzle-orm';
+import { buildSafeJsonPath } from '../../src/models/eval';
+
+const jsonPath = buildSafeJsonPath(userField);
+const query = sql`
+  SELECT * FROM eval_results
+  WHERE json_extract(metadata, ${jsonPath}) = ${value}
+`;
+```
+
+If you need a new JSON-path helper, match the guarantees in `buildSafeJsonPath` and keep the implementation audited in one shared utility.
+
+## Passing SQL Fragments Between Functions
+
+When building complex queries, pass `SQL<unknown>` fragments instead of strings:
+
+```typescript
+import { type SQL, sql } from 'drizzle-orm';
+
+function queryWithFilter(whereSql: SQL<unknown>): Promise<Result[]> {
+  const query = sql`SELECT * FROM eval_results WHERE ${whereSql}`;
+  return db.all(query);
+}
+
+const filter = sql`eval_id = ${evalId} AND success = ${1}`;
+const results = await queryWithFilter(filter);
+```
+

+# Dependency Management
+
+## Safe Update Workflow
+
+Use `--target minor` for safe minor/patch updates only:
+
+```bash
+# Check all three locations for available updates
+npx npm-check-updates --target minor              # Root
+npx npm-check-updates --target minor --cwd site   # Site workspace
+npx npm-check-updates --target minor --cwd src/app # App workspace
+
+# Apply updates with -u flag
+npx npm-check-updates --target minor -u
+npx npm-check-updates --target minor -u --cwd site
+npx npm-check-updates --target minor -u --cwd src/app
+
+# Install and verify
+npm install
+npm run build && npm test && npm run lint && npm run format:check
+
+# Check version consistency (required by CI)
+npx check-dependency-version-consistency
+```
+
+## Critical Rules
+
+1. **Version consistency across workspaces** - All workspaces must use the same version of shared dependencies. CI enforces this via `check-dependency-version-consistency`.
+
+2. **Update examples/** - 20+ package.json files in examples/ are user-facing; keep them current when updating dependencies.
+
+3. **Run `npm audit`** - Use `npm audit` or `npm run audit:fix` to check for security vulnerabilities across all workspaces. Do not let `npm audit fix` lockfile drift ride along with an unrelated change; ship audit-driven updates as their own PR.
+
+4. **If updates fail** - Revert the problematic package and keep the current version. Don't force incompatible updates.
+
+5. **Test before committing** - Always run `npm run build && npm test` after updating dependencies.
+
+## Major Updates
+
+```bash
+# See available major updates (don't apply automatically)
+npx npm-check-updates --target latest
+
+# Major updates often require code changes - evaluate each carefully
+```
+
+Major updates require careful evaluation:
+
+- Check the changelog for breaking changes
+- Look for migration guides
+- Test thoroughly before merging
+
+## Workspaces
+
+The project uses npm workspaces. Updates must be checked in all three locations:
+
+- Root (`/`) - Core library dependencies
+- Site (`/site`) - Documentation site (Docusaurus)
+- App (`/src/app`) - Web UI (React/Vite)
+
+## Working on Renovate Branches
+
+Renovate force-pushes its branches whenever `main` changes or someone comments
+`@renovate rebase`. Any manual commit you add may be overwritten without warning.
+
+- Push fixes quickly and expect them to survive only until the next Renovate rebase.
+- For non-trivial manual work on a Renovate-managed dependency, create a sibling
+  branch off the Renovate branch and open a separate PR that Renovate will not touch.
+- On a major-version Renovate PR, read the upstream changelog, run gap analysis on
+  our matching provider/integration and its docs, then test end-to-end with real evals
+  (`npm run local -- eval -c <example>.yaml --no-cache -o output.json`, adding
+  `--env-file .env` when credentials are needed and the file exists)
+  before deciding whether the upgrade needs code changes.
+
+## Useful Commands
+
+```bash
+# Fix security vulnerabilities in all workspaces
+npm run audit:fix
+
+# Check for outdated packages
+npm outdated
+
+# See why a package is installed
+npm explain <package-name>
+
+# Check for unused dependencies
+npm run depcheck

+**Forbidden commands:**
+
+- `git push origin main`
+- `git merge feature-branch` while on main
+- Any direct commits to main
+
+All changes to main MUST go through pull requests.
+
+## Commit Policy
+
+**"Explicitly asked"** = user says "amend", "squash", "rebase", or "fix up the commit".
+
+"Looks good" or "go ahead" is NOT permission to rewrite history.
+
+## Standard Workflow
+
+### 1. Create Feature Branch
+
+```bash
+git checkout main
+git pull origin main
+git checkout -b feature/your-branch-name
+```
+
+### 2. Make Changes and Commit
+
+```bash
+git add <specific-files>    # NEVER blindly add everything
+git commit -m "type(scope): description"
+```
+
+See `docs/agents/pr-conventions.md` for commit message format.
+
+### 3. Lint and Format
+
+```bash
+npm run l    # Lint changed files
+npm run f    # Format changed files
+```
+
+Fix any errors before proceeding.
+
+### 4. Sync with Main
+
+```bash
+git fetch origin main
+git merge origin/main
+```
+
+Resolve any conflicts before pushing.
+
+### 5. Push and Create PR
+
+```bash
+git push -u origin feature/your-branch-name
+gh pr create --title "type(scope): description" --body "PR description"
+```
+
+### 6. Wait for Review
+
+Wait for CI checks to pass and code review approval before merging.
+
+## Key Points
+
+- **Never blindly `git add .`** - there may be unrelated files
+- **Always sync with main** before creating PR to avoid conflicts
+- **Don't edit CHANGELOG.md** - it's auto-generated

+# Logging Guidelines
+
+## The Rule
+
+Always use the logger with an object as the second parameter:
+
+```typescript
+logger.debug('[Component] Message', { headers, body, config });
+```
+
+The object is **auto-sanitized** - sensitive fields are automatically redacted.
+
+## Why This Matters
+
+- **Security**: Prevents accidental exposure of secrets in logs
+- **Consistency**: Structured logs are easier to search and analyze
+- **Safety**: Red team test content may contain harmful/sensitive data
+
+## Correct Usage
+
+```typescript
+import logger from './logger';
+
+// Good - context object is auto-sanitized
+logger.debug('[Provider]: Making API request', {
+  url: 'https://api.example.com',
+  method: 'POST',
+  headers: { Authorization: 'Bearer secret-token' },
+  body: { apiKey: 'secret-key', data: 'value' },
+});
+// Output: Authorization and apiKey are [REDACTED]
+
+logger.error('Request failed', {
+  headers: response.headers,
+  body: errorResponse,
+});
+```
+
+## Anti-Pattern
+
+```typescript
+// WRONG - exposes secrets, bypasses sanitization
+logger.debug(`Config: ${JSON.stringify(config)}`);
+logger.debug(`Calling ${url} with headers: ${JSON.stringify(headers)}`);
+```
+
+## Manual Sanitization
+
+For non-logging contexts:
+
+```typescript
+import { sanitizeObject } from './util/sanitizer';
+
+const sanitizedConfig = sanitizeObject(providerConfig, {
+  context: 'provider config',
+});
+```
+
+## What Gets Sanitized
+
+Field names containing (case-insensitive, works with `-`, `_`, camelCase):
+
+| Category     | Fields                                                                     |
+| ------------ | -------------------------------------------------------------------------- |
+| Passwords    | `password`, `passwd`, `pwd`, `passphrase`                                  |
+| API Keys     | `apiKey`, `api_key`, `token`, `accessToken`, `refreshToken`, `bearerToken` |
+| Secrets      | `secret`, `clientSecret`, `webhookSecret`                                  |
+| Headers      | `authorization`, `cookie`, `x-api-key`, `x-auth-token`                     |
+| Certificates | `privateKey`, `certificatePassword`, `keystorePassword`                    |
+| Signatures   | `signature`, `sig`, `signingKey`                                           |

+# Pull Request Conventions
+
+PR titles follow Conventional Commits format. They become squash-merge commit messages and changelog entries.
+
+## Format
+
+```plaintext
+<type>(<scope>): <description>
+<type>(<scope>)!: <description>  # Breaking changes
+```
+
+### Description Guidelines
+
+- **Imperative mood**: "add feature" not "added" or "adds"
+- **Lowercase**: except proper nouns and acronyms (FERPA, OAuth, MUI)
+- **No trailing period**
+- **Be specific**: describe what changed, not that something changed
+- **~50 characters**: GitHub truncates long titles
+
+## Types
+
+| Type       | Use For                                               |
+| ---------- | ----------------------------------------------------- |
+| `feat`     | New CLI feature or major webui feature                |
+| `fix`      | Bug fix in CLI or major webui bug fix                 |
+| `chore`    | Maintenance, upgrades, minor fixes, non-user-facing   |
+| `refactor` | Code restructuring without behavior change            |
+| `docs`     | Documentation only (use with `site` scope for site/)  |
+| `test`     | Test-only changes (new tests, test fixes, test infra) |
+| `ci`       | CI/CD changes                                         |
+| `revert`   | Revert previous change                                |
+| `perf`     | Performance improvement                               |
+
+**Changelog visibility:** Only `feat`, `fix`, and breaking changes (`!`) appear in release notes. Use `ci`, `chore`, `test`, `docs`, or `refactor` for changes that shouldn't be user-facing.
+
+**Breaking changes:** Add `!` after scope: `feat(api)!:`, `chore(deps)!:`
+
+### Test vs Fix
+
+Use `test:` when the PR **only** contains test changes:
+
+- Adding new tests
+- Fixing broken/flaky tests
+- Fixing lint errors in test files
+- Test infrastructure changes
+
+Use `fix:` when fixing bugs in **application code** (even if tests are included):
+
+- Bug fix in `src/` with accompanying test changes → `fix:`
+- Lint error in test file only → `test:`
+
+### Type Selection for Mixed Changes
+
+Use the **primary change** to determine type:
+
+| PR Contains                       | Type       | Why                              |
+| --------------------------------- | ---------- | -------------------------------- |
+| Bug fix + new tests               | `fix`      | Fix is primary, tests support it |
+| Feature + documentation           | `feat`     | Feature is primary               |
+| Only test changes                 | `test`     | No application code changed      |
+| Only doc changes                  | `docs`     | No application code changed      |
+| Minor webui fix (styling, typos)  | `chore`    | Not a major user-facing fix      |
+| Refactor + minor fixes discovered | `refactor` | Refactor was the intent          |
+
+**Major webui changes** = new pages, significant UX changes, core functionality bugs
+
+**Minor webui changes** = styling tweaks, copy changes, internal refactors → use `chore`
+
+## Scope Selection (Priority Order)
+
+### 1. Feature Domains (HIGHEST PRIORITY)
+
+**`redteam` - MANDATORY when redteam is the PR's primary change or product surface:**
+
+- Plugins, strategies, grading
+- UI components (setup, report, config dialogs)
+- CLI commands, server endpoints
+- Documentation, examples
+- Redteam-specific tests, fixtures, utilities, and behavior changes
+
+**Other feature domains:** `providers`, `assertions`, `eval`, `api`, `db`
+
+### 2. Product Areas
+
+- `webui` - React app in `src/app/`
+- `cli` - CLI in `src/`
+- `server` - Web server in `src/server/`
+
+**Note:** Documentation site changes use `docs(site):`, not a standalone `site` scope.
+
+### 3. Technical/Infrastructure
+
+- `deps` - Dependency updates
+- `ci` - CI/CD pipelines, GitHub Actions
+- `tests` - Test infrastructure
+- `build` - Build tooling
+- `examples` - Non-redteam examples
+
+### 4. Specialized
+
+`auth`, `cache`, `config`, `python`, `mcp`, `code-scan`
+
+### 5. No Scope
+
+For generic/cross-cutting changes: `chore: bump version 0.119.11`
+
+## THE REDTEAM RULE
+
+**If a PR is primarily redteam-related, use `(redteam)` scope.**
+
+This applies even if the redteam change is only in UI, CLI, docs, examples, utilities, tests, or server endpoints.
+
+For broad, cross-cutting maintenance PRs, do **not** choose `(redteam)` solely because one touched file lives under `src/redteam/` or because one generic helper is also used by redteam. Use the PR's primary purpose/scope and call out the redteam-adjacent touch in the PR description when it is review-relevant.
+
+❌ **Wrong:**
+
+```plaintext
+fix(webui): fix Basic strategy checkbox in red team setup
+feat(cli): add redteam validate command
+chore(redteam): resolve repo-wide lint findings
+```
+
+✅ **Correct:**
+
+```plaintext
+fix(redteam): fix Basic strategy checkbox in setup UI
+feat(redteam): add validate target CLI command
+chore: resolve repo-wide lint findings
+```
+
+**Why?** Redteam spans CLI, webui, server, docs, and examples. Consistent scoping makes it easy to find all redteam work.
+
+## Decision Tree
+
+```plaintext
+1. Is the PR primarily redteam-related? → Use (redteam)
+2. Is it another feature domain? → Use that scope
+3. Is it localized to one product area? → Use that scope
+4. Is it infrastructure? → Use that scope
+5. Otherwise → No scope
+```
+
+## Dependency Updates
+
+- **`fix(deps)`** - Patch versions (security/bug fixes)
+- **`chore(deps)`** - Minor/major upgrades, bulk updates, dev dependencies
+
+## Examples
+
+✅ **Good:**
+
+```plaintext
+feat(redteam): add FERPA compliance plugin
+feat(cli): add --json output flag to eval command
+fix(cli): handle empty config file gracefully
+fix(webui): fix pagination crash on empty results
+chore(webui): update button styling on settings page
+docs(site): add guide for custom providers
+chore(deps): update Material-UI monorepo to v8 (major)
+fix(deps): update dependency zod to v4.2.0
+feat(api)!: simplify provider interface
+chore: bump version 0.119.11
+test: add smoke tests for CLI commands
+test(redteam): fix flaky plugin integration tests
+```
+
+❌ **Bad:**
+
+```plaintext
+feat: add new redteam thing         # Missing (redteam) scope
+fix(webui): red team checkbox       # Should be fix(redteam)
+chore(webui): update dependency     # Should be chore(deps)
+feat: stuff                         # Too vague
+fix: bug fix                        # What bug? Be specific
+Fix(cli): Add feature               # Wrong case, not imperative
+fix(test): resolve lint errors      # Should be test: (test-only)
+docs: update site                   # Should be docs(site):
+site: update guides                 # Should be docs(site):
+feat(webui): minor styling update   # Minor = chore, not feat
+```
+
+## Draft vs Ready
+
+Open PRs **ready for review** by default:
+
+```bash
+gh pr create --title "feat(scope): description" --body "..."
+```
+
+Use `--draft` only when:
+
+- The user explicitly asks for a draft
+- The work is an intentional WIP parked for a hand-off
+- The PR blocks on an external dependency that must land first
+- The PR addresses an unpublished security advisory (see root `AGENTS.md`
+  "Security-Sensitive PRs")
+
+## Commit & PR Attribution
+
+- **Never attribute commits or PR bodies to Claude / Claude Code.** Do not add
+  `Co-Authored-By: Claude…` trailers, "Generated with Claude Code" footers, or
+  similar markers. Use your configured git identity only.
+- Do not add marketing-style suffixes to commit subjects.
+
+## GitHub Interaction Rules
+
+- **NEVER comment on GitHub issues** - Only create PRs to address issues
+- **NEVER close issues** - Let maintainers close issues after PR merge
+- Focus on creating high-quality PRs that fully address the issue
+
+## Checklist Before Creating PR
+
+1. Is this PR primarily redteam-related? → Use `(redteam)` scope
+2. Choose correct type
+3. Choose correct scope using priority order
+4. Breaking change? Add `!` after scope
+5. Run `npm run l && npm run f`
+6. Open ready-for-review (omit `--draft`) unless one of the exceptions above applies
+7. Do **not** add Claude attribution trailers or footers

+# Python Guidelines
+
+For Python providers, prompts, assertions, and scripts.
+
+## Requirements
+
+- Python 3.8 or later
+- Follow [Google Python Style Guide](https://google.github.io/styleguide/pyguide.html)
+- Use type hints for readability and error catching
+
+## Linting & Formatting
+
+Use `ruff` for both:
+
+```bash
+ruff check --fix           # Lint with auto-fix
+ruff check --select I --fix # Sort imports
+ruff format                 # Format code
+```
+
+## Testing
+
+Use the built-in `unittest` module for new Python tests.
+
+## Best Practices
+
+- Keep dependencies minimal - avoid unnecessary external packages
+- When adding examples, update relevant `requirements.txt` files
+- Follow promptfoo API patterns for custom providers/prompts/assertions
+- Write unit tests for new Python functions
+
+## Provider Pattern
+
+```python
+def call_api(prompt: str, options: dict, context: dict) -> dict:
+    """
+    Args:
+        prompt: The prompt string
+        options: Provider configuration
+        context: Variables from the test case
+
+    Returns:
+        dict with 'output' key (and optionally 'error')
+    """
+    # Implementation
+    return {"output": response_text}
+```
+
+## Assertion Pattern
+
+```python
+def get_assert(output: str, context: dict) -> dict:
+    """
+    Args:
+        output: The provider's output
+        context: Test context including vars
+
+    Returns:
+        dict with 'pass' (bool) and optionally 'reason'

+| `view-server`      | `src/server`                                                     | Local server and API routes                     |

+| `legacy-runtime`   | Mixed top-level runtime modules                                  | Transitional modules awaiting narrower owners   |
+
+The source of truth for these temporary private layers is
+`architecture/layers.json`.
+
+## First Enforced Rule
+
+Internal modules must not import `src/index.ts`.
+
+`src/index.ts` is the public facade. Importing it from inside the product makes
+the dependency graph point inward through the public API, which makes later
+package extraction harder and can hide cycles.
+
+Run the check with:
+
+```bash
+npm run architecture:check
+```
+
+## First Leaf Layer
+
+`src/contracts` and its `src/contracts.ts` public entrypoint are the first intentionally
+leaf-safe surface. They currently own the dependency-free-or-`zod` subset that can plausibly become a future
+`@promptfoo/schema` package:
+
+- shared token/input contracts
+- browser-safe common and user API DTOs
+- portable blob references and provider-neutral capability/result contracts
+- provider environment override schema
+- prompt contracts and prompt validation
+- transform contracts and shared transform validation
+
+The older `src/types` and `src/validators` paths remain as compatibility shims or
+mixed transitional modules. They are useful public/internal surfaces today, but
+they are not yet clean enough to call a package boundary.
+
+Leaf layers may import only themselves plus the external packages on their
+`allowedExternal` allowlist in `architecture/layers.json` (`contracts` allows only
+`zod`). The same architecture check enforces both halves of the rule, so this first
+extracted surface can neither grow back upward into Node, provider, or redteam code,
+nor quietly pick up a new npm dependency or Node builtin such as `node:fs`. A
+`node:` prefix is ignored when matching, so `"fs"` and `"node:fs"` are equivalent.
+
+## Layer Dependency Ratchet
+
+Each private layer declares its currently allowed dependencies in
+`architecture/layers.json`. The current graph still has transitional edges, so
+the allowlist records today's honest baseline rather than pretending the final
+package topology already exists. New cross-layer relationships fail
+`npm run architecture:check` until they are reviewed explicitly.
+
+Mixed modules that do not yet have a stable package owner belong to
+`legacy-runtime`. This keeps migration debt visible. New checked source files
+must be assigned to a layer instead of silently becoming unclassified.
+
+`src/evaluator/runtime.ts` defines the evaluator's narrow runtime port. The
+`EvaluationStore` contract owns result append/read, prompt updates, resume lookup,
+comparison-result saves, and final evaluation persistence. The default
+`src/node/evaluationStore.ts` adapter maps that port to the existing `Eval` and
+`EvalResult` models, while `src/evaluator/inMemoryStore.ts` provides a
+dependency-light state implementation for embedded evaluators and focused tests.
+`src/node/evaluatorRuntime.ts` continues to own JSONL writer construction and
+resume append behavior. The evaluator orchestrates evaluation behavior without
+importing the concrete `Eval` model.
+
+The checker also resolves cross-layer source aliases such as `@promptfoo/*`.
+The browser-only `@app/*` alias stays inside the `app` layer. Alias spelling
+does not exempt a browser import from the same layer and path checks as a
+relative import.
+
+## DAG Progress Ratchets
+
+The architecture check also measures the layer dependency graph so it can move
+toward a directed acyclic graph without regressing:
+
+- `maxStronglyConnectedComponentSize` limits the size of the largest remaining
+  layer cycle.
+- `architecture/edge-baseline.json` limits every existing cross-layer edge to
+  its reviewed import count and rejects new edges.
+- `forbiddenDependencies` permanently locks layer pairs whose direct or
+  transitive dependency has been removed.
+- `tierOrder` lists every layer in the intended bottom-to-top topology so the
+  checker can report the remaining back-edges.
+
+After intentionally reducing or otherwise reviewing cross-layer coupling, run
+`npm run architecture:baseline` and include the baseline change in review. Do
+not refresh the baseline merely to make a newly introduced dependency pass.
+
+## Browser Import Ratchet
+
+The `app` layer has an additional internal-path allowlist. It pins the existing
+browser-to-runtime imports while DTOs and presentation helpers move into a
+browser-safe package surface. A new app import from root runtime code fails the
+architecture check even when the broader layer relationship already exists.
+
+When moving an existing browser import to a narrower surface, remove its old
+path from the allowlist. Avoid adding paths unless the dependency is
+intentionally browser-safe. Allowlist entries are exact files, not directory
+roots.
+
+## Dependency Ownership Report
+
+The dependency report groups direct runtime imports by the private layer that
+currently uses them:
+
+```bash
+npm run deps:ownership
+```
+
+The report is intentionally descriptive for now. It gives us the evidence needed
+to move dependencies into future packages without guessing at ownership.

+# Plugins State Management Refactor Implementation Plan
+
+## Overview
+
+Refactor `Plugins.tsx` to remove interstitial state management between `PluginsTab.tsx` and the Zustand store. The current implementation maintains duplicate local state (`selectedPlugins`, `pluginConfig`, `hasUserInteracted`) with bi-directional sync effects. This refactor will derive state directly from the store and update the store directly on user interactions.
+
+## Current State Analysis
+
+### Three-Layer Architecture (to be simplified)
+
+1. **Global State**: Zustand store (`useRedTeamConfig.ts`) - source of truth
+2. **Local State**: `Plugins.tsx` maintains `selectedPlugins`, `pluginConfig`, `hasUserInteracted`
+3. **Props**: `PluginsTab.tsx` receives state via props
+
+### Key Files
+
+- `src/app/src/pages/redteam/setup/components/Plugins.tsx` - Parent component with local state
+- `src/app/src/pages/redteam/setup/components/PluginsTab.tsx` - Child component receiving props
+- `src/app/src/pages/redteam/setup/hooks/useRedTeamConfig.ts` - Zustand store
+
+### Current State Variables to Remove (Plugins.tsx)
+
+- `const [selectedPlugins, setSelectedPlugins]` - lines 112-118
+- `const [hasUserInteracted, setHasUserInteracted]` - line 135
+- `const [pluginConfig, setPluginConfig]` - lines 136-144
+
+### Current Sync Effects to Remove (Plugins.tsx)
+
+- Effect 1 (lines 152-168): Syncs store → local state when `!hasUserInteracted`
+- Effect 2 (lines 171-199): Syncs local state → store when `hasUserInteracted`
+
+### Store Protection Already Exists
+
+The `updatePlugins` method (useRedTeamConfig.ts:272-311) already:
+
+- Merges new plugin configs with existing configs
+- Compares output vs current state to prevent infinite loops
+- Only triggers updates when state actually changed
+
+## Desired End State
+
+After this refactor:
+
+1. `Plugins.tsx` derives `selectedPlugins` and `pluginConfig` from `config.plugins` using `useMemo`
+2. All plugin mutations go directly to the Zustand store
+3. No local state synchronization effects
+4. `PluginsTab` has a new `setSelectedPlugins` prop for efficient bulk operations
+5. `onUserInteraction` prop is removed from `PluginsTab`
+
+### How to Verify
+
+1. All tests in `PluginsTab.test.tsx` pass
+2. Preset selection works (plugins are set correctly in store)
+3. Individual plugin toggle works (checkbox toggles update store)
+4. Select All/None buttons work correctly
+5. Clear All button works correctly
+6. Plugin configs (e.g., for `indirect-prompt-injection`) are preserved when toggling
+
+## What We're NOT Doing
+
+- Changing the Zustand store implementation
+- Modifying `CustomIntentsTab` or `CustomPoliciesTab`
+- Changing how policy/intent plugins are handled
+- Refactoring the `PluginConfigDialog` component
+- Changing test structure or test helpers
+
+## Implementation Approach
+
+The refactoring follows these principles:
+
+1. **Remove duplicate state** - No local state that mirrors the store
+2. **Derive, don't store** - Use `useMemo` to compute `selectedPlugins` and `pluginConfig` from `config.plugins`
+3. **Direct store updates** - All mutations go straight to `updatePlugins`
+4. **Efficient bulk operations** - Add `setSelectedPlugins` for presets and bulk selection
+
+---
+
+## Phase 1: Refactor `Plugins.tsx`
+
+### Overview
+
+Remove local state and sync effects, replace with derived values and direct store updates.
+
+### Changes Required:
+
+#### 1. Remove Local State Variables
+
+**File**: `src/app/src/pages/redteam/setup/components/Plugins.tsx`
+
+**Remove lines 112-118** (selectedPlugins state):
+
+```tsx
+// REMOVE THIS:
+const [selectedPlugins, setSelectedPlugins] = useState<Set<Plugin>>(() => {
+  return new Set(
+    config.plugins
+      .map((plugin) => (typeof plugin === 'string' ? plugin : plugin.id))
+      .filter((id) => id !== 'policy' && id !== 'intent') as Plugin[],
+  );
+});
+```
+
+**Remove line 135** (hasUserInteracted state):
+
+```tsx
+// REMOVE THIS:
+const [hasUserInteracted, setHasUserInteracted] = useState(false);
+```
+
+**Remove lines 136-144** (pluginConfig state):
+
+```tsx
+// REMOVE THIS:
+const [pluginConfig, setPluginConfig] = useState<LocalPluginConfig>(() => {
+  const initialConfig: LocalPluginConfig = {};
+  config.plugins.forEach((plugin) => {
+    if (typeof plugin === 'object' && plugin.config) {
+      initialConfig[plugin.id] = plugin.config;
+    }
+  });
+  return initialConfig;
+});
+```
+
+#### 2. Add Derived Values
+
+**Add after the store hook calls (after line 108):**
+
+```tsx
+// Derive selectedPlugins from config.plugins
+const selectedPlugins = useMemo(() => {
+  return new Set(
+    config.plugins
+      .map((plugin) => (typeof plugin === 'string' ? plugin : plugin.id))
+      .filter((id) => id !== 'policy' && id !== 'intent') as Plugin[],
+  );
+}, [config.plugins]);
+
+// Derive pluginConfig from config.plugins
+const pluginConfig = useMemo(() => {
+  const configs: LocalPluginConfig = {};
+  config.plugins.forEach((plugin) => {
+    if (typeof plugin === 'object' && plugin.config) {
+      configs[plugin.id] = plugin.config;
+    }
+  });
+  return configs;
+}, [config.plugins]);
+```
+
+#### 3. Remove Sync Effects
+
+**Remove lines 152-168** (Effect 1 - config → local sync):
+
+```tsx
+// REMOVE THIS ENTIRE EFFECT:
+useEffect(() => {
+  if (!hasUserInteracted) {
+    const configPlugins = new Set(
+      config.plugins
+        .map((plugin) => (typeof plugin === 'string' ? plugin : plugin.id))
+        .filter((id) => id !== 'policy' && id !== 'intent') as Plugin[],
+    );
+    if (
+      configPlugins.size !== selectedPlugins.size ||
+      !Array.from(configPlugins).every((plugin) => selectedPlugins.has(plugin))
+    ) {
+      setSelectedPlugins(configPlugins);
+    }
+  }
+}, [config.plugins, hasUserInteracted, selectedPlugins]);
+```
+
+**Remove lines 171-199** (Effect 2 - local → config sync):
+
+```tsx
+// REMOVE THIS ENTIRE EFFECT:
+useEffect(() => {
+  if (hasUserInteracted) {
+    const policyPlugins = config.plugins.filter((p) => typeof p === 'object' && p.id === 'policy');
+    const intentPlugins = config.plugins.filter((p) => typeof p === 'object' && p.id === 'intent');
+    const regularPlugins = Array.from(selectedPlugins).map((plugin) => {
+      const existingConfig = pluginConfig[plugin];
+      if (existingConfig && Object.keys(existingConfig).length > 0) {
+        return {
+          id: plugin,
+          config: existingConfig,
+        };
+      }
+      return plugin;
+    });
+    const allPlugins = [...regularPlugins, ...policyPlugins, ...intentPlugins];
+    updatePlugins(allPlugins as Array<string | { id: string; config: any }>);
+  }
+}, [selectedPlugins, pluginConfig, hasUserInteracted, config.plugins, updatePlugins]);
+```
+
+#### 4. Refactor `handlePluginToggle`
+
+**Replace the current implementation (lines 201-236) with:**
+
+```tsx
+const handlePluginToggle = useCallback(
+  (plugin: Plugin) => {
+    // Preserve policy and intent plugins
+    const policyPlugins = config.plugins.filter((p) => typeof p === 'object' && p.id === 'policy');
+    const intentPlugins = config.plugins.filter((p) => typeof p === 'object' && p.id === 'intent');
+
+    // Get current regular plugins (excluding policy/intent)
+    const currentRegularPlugins = config.plugins.filter((p) => {
+      const id = typeof p === 'string' ? p : p.id;
+      return id !== 'policy' && id !== 'intent';
+    });
+
+    const isCurrentlySelected = selectedPlugins.has(plugin);
+
+    let newRegularPlugins: Config['plugins'];
+
+    if (isCurrentlySelected) {
+      // Remove the plugin
+      newRegularPlugins = currentRegularPlugins.filter((p) => {
+        const id = typeof p === 'string' ? p : p.id;
+        return id !== plugin;
+      });
+    } else {
+      // Add the plugin
+      addPlugin(plugin); // Add to recently used
+      newRegularPlugins = [...currentRegularPlugins, plugin];
+    }
+
+    // Combine all plugins and update store
+    const allPlugins = [...newRegularPlugins, ...policyPlugins, ...intentPlugins];
+    updatePlugins(allPlugins);
+  },
+  [config.plugins, selectedPlugins, updatePlugins, addPlugin],
+);
+```
+
+#### 5. Add `setSelectedPlugins` Handler for Bulk Operations
+
+**Add after `handlePluginToggle`:**
+
+```tsx
+const setSelectedPlugins = useCallback(
+  (newSelectedPlugins: Set<Plugin>) => {
+    // Preserve policy and intent plugins
+    const policyPlugins = config.plugins.filter((p) => typeof p === 'object' && p.id === 'policy');
+    const intentPlugins = config.plugins.filter((p) => typeof p === 'object' && p.id === 'intent');
+
+    // Create new plugins array, preserving configs from existing plugins
+    const newPluginsArray: Config['plugins'] = Array.from(newSelectedPlugins).map((plugin) => {
+      const existing = config.plugins.find((p) => (typeof p === 'string' ? p : p.id) === plugin);
+      if (existing && typeof existing === 'object' && existing.config) {
+        return existing; // Preserve existing config
+      }
+      return plugin;
+    });
+
+    // Combine all plugins and update store
+    const allPlugins = [...newPluginsArray, ...policyPlugins, ...intentPlugins];
+    updatePlugins(allPlugins);
+  },
+  [config.plugins, updatePlugins],
+);
+```
+
+#### 6. Refactor `updatePluginConfig`
+
+**Replace the current implementation (lines 238-257) with:**
+
+```tsx
+const updatePluginConfig = useCallback(
+  (plugin: string, newConfig: Partial<LocalPluginConfig[string]>) => {
+    // Build new plugins array with updated config
+    const newPlugins = config.plugins.map((p) => {
+      const id = typeof p === 'string' ? p : p.id;
+      if (id === plugin) {
+        const existingConfig = typeof p === 'object' ? p.config || {} : {};
+        return {
+          id: plugin,
+          config: { ...existingConfig, ...newConfig },
+        };
+      }
+      return p;
+    });
+
+    updatePlugins(newPlugins);
+  },
+  [config.plugins, updatePlugins],
+);
+```
+
+#### 7. Update PluginsTab Props
+
+**Update the PluginsTab component call (around line 431):**
+
+```tsx
+<PluginsTab
+  selectedPlugins={selectedPlugins}
+  handlePluginToggle={handlePluginToggle}
+  setSelectedPlugins={setSelectedPlugins} // NEW PROP
+  pluginConfig={pluginConfig}
+  updatePluginConfig={updatePluginConfig}
+  recentlyUsedPlugins={recentlyUsedSnapshot}
+  isRemoteGenerationDisabled={isRemoteGenerationDisabled}
+/>
+```
+
+**Remove** the `onUserInteraction` prop.
+
+### Success Criteria:
+
+#### Automated Verification:
+
+- [x] TypeScript compilation passes: `npm run tsc` from `src/app`
+- [x] Linting passes: `npm run lint`
+- [x] All PluginsTab tests pass: `npm run test:app -- src/pages/redteam/setup/components/PluginsTab.test.tsx`
+
+**Implementation Note**: After completing this phase and all automated verification passes, proceed to Phase 2.
+
+---
+
+## Phase 2: Update `PluginsTab.tsx`
+
+### Overview
+
+Update the PluginsTab component to use the new `setSelectedPlugins` prop and remove `onUserInteraction`.
+
+### Changes Required:
+
+#### 1. Update Props Interface
+
+**File**: `src/app/src/pages/redteam/setup/components/PluginsTab.tsx`
+
+**Replace lines 64-72:**
+
+```tsx
+export interface PluginsTabProps {
+  selectedPlugins: Set<Plugin>;
+  handlePluginToggle: (plugin: Plugin) => void;
+  setSelectedPlugins: (plugins: Set<Plugin>) => void; // NEW
+  pluginConfig: LocalPluginConfig;
+  updatePluginConfig: (plugin: string, newConfig: Partial<LocalPluginConfig[string]>) => void;
+  recentlyUsedPlugins: Plugin[];
+  isRemoteGenerationDisabled: boolean;
+  // REMOVED: onUserInteraction
+}
+```
+
+#### 2. Update Component Parameters
+
+**Update lines 74-82:**
+
+```tsx
+export default function PluginsTab({
+  selectedPlugins,
+  handlePluginToggle,
+  setSelectedPlugins,  // NEW
+  pluginConfig,
+  updatePluginConfig,
+  recentlyUsedPlugins,
+  isRemoteGenerationDisabled,
+}: PluginsTabProps): React.ReactElement {
+```
+
+#### 3. Refactor `handlePresetSelect`
+
+**Replace the current implementation (around lines 367-392):**
+
+```tsx
+const handlePresetSelect = useCallback(
+  (preset: { name: string; plugins: Set<Plugin> | ReadonlySet<Plugin> }) => {
+    recordEvent('feature_used', {
+      feature: 'redteam_config_plugins_preset_selected',
+      preset: preset.name,
+    });
+    if (preset.name === 'Custom') {
+      setIsCustomMode(true);
+    } else {
+      // Use setSelectedPlugins for efficient bulk update
+      setSelectedPlugins(new Set(preset.plugins as Set<Plugin>));
+      setIsCustomMode(false);
+    }
+  },
+  [recordEvent, setSelectedPlugins],
+);
+```
+
+#### 4. Refactor "Select All" Button
+
+**Replace lines 485-494:**
+
+```tsx
+onClick={() => {
+  // Collect all filtered plugins and merge with existing selection
+  const newSelected = new Set(selectedPlugins);
+  filteredPlugins.forEach(({ plugin }) => {
+    newSelected.add(plugin);
+  });
+  setSelectedPlugins(newSelected);
+}}
+```
+
+#### 5. Refactor "Select None" Button
+
+**Replace lines 499-508:**
+
+```tsx
+onClick={() => {
+  // Remove only the filtered plugins from selection
+  const filteredPluginIds = new Set(filteredPlugins.map((p) => p.plugin));
+  const newSelected = new Set(
+    [...selectedPlugins].filter((p) => !filteredPluginIds.has(p)),
+  );
+  setSelectedPlugins(newSelected);
+}}
+```
+
+#### 6. Refactor "Clear All" Button
+
+**Replace lines 816-820:**
+
+```tsx
+onClick={() => {
+  setSelectedPlugins(new Set());
+}}
+```
+
+### Success Criteria:
+
+#### Automated Verification:
+
+- [x] TypeScript compilation passes: `npm run tsc` from `src/app`
+- [x] Linting passes: `npm run lint`
+- [x] All PluginsTab tests pass: `npm run test:app -- src/pages/redteam/setup/components/PluginsTab.test.tsx`
+
+**Implementation Note**: After completing this phase and all automated verification passes, proceed to Phase 3.
+
+---
+
+## Phase 3: Verify and Fix Tests
+
+### Overview
+
+Run the full test suite and fix any test failures. Tests should mostly pass since they test end-to-end behavior (user interaction → store state), not implementation details.
+
+### Changes Required:
+
+#### 1. Run Full Test Suite
+
+```bash
+cd src/app
+npm run test -- src/pages/redteam/setup/components/PluginsTab.test.tsx
+```
+
+#### 2. Potential Test Adjustments
+
+The tests should largely pass as-is because they:
+
+- Verify store state after interactions (still works)
+- Use `userEvent` to simulate clicks (still works)
+- Don't mock the intermediate state management
+
+However, if any tests reference `onUserInteraction` in expectations or setup, they will need updates.
+
+**If needed, remove references to `onUserInteraction` in test mocks or assertions.**
+
+### Success Criteria:
+
+#### Automated Verification:
+
+- [x] All 30+ tests in `PluginsTab.test.tsx` pass (44 tests passed)
+- [x] No TypeScript errors
+- [x] No linting errors
+
+#### Manual Verification:
+
+- [x] Start the dev server: `npm run dev:app`
+- [x] Navigate to Red Team Setup → Plugins page
+- [x] Select a preset (e.g., "Recommended") → verify plugins appear selected
+- [x] Toggle individual plugins → verify selection updates
+- [x] Use "Select all" → verify all visible plugins are selected
+- [x] Use "Select none" → verify filtered plugins are deselected
+- [x] Use "Clear All" in sidebar → verify all plugins are cleared
+- [x] Select `indirect-prompt-injection`, configure it, then toggle other plugins → verify config is preserved
+- [x] Refresh page → verify plugin selection persists (Zustand persistence)
+
+**Implementation Note**: ✅ All automated and manual verification complete. Refactor is complete.
+
+---
+
+## Testing Strategy
+
+### Unit Tests (Existing)
+
+The existing test suite in `PluginsTab.test.tsx` covers:
+
+- Component rendering
+- Plugin search filtering
+- Category filtering
+- Selected plugins list display
+- Preset selection → store update
+- Plugin list item toggle → store update
+- Select All/None → store update
+- Clear All → store update
+
+### Key Test Scenarios to Verify
+
+1. **Preset Selection**: Clicking a preset card results in correct plugins in store
+2. **Single Plugin Toggle**: Clicking checkbox adds/removes plugin from store
+3. **Select All**: All filtered plugins added to store
+4. **Select None**: All filtered plugins removed from store (preserving others)
+5. **Clear All**: All plugins removed from store
+6. **Config Preservation**: Plugin configs survive toggle operations
+
+### Edge Cases
+
+- Toggling a plugin that requires configuration
+- Preserving policy/intent plugins during regular plugin operations
+- Rapid toggling (React batching)
+
+## Performance Considerations
+
+### Improvements
+
+- **Bulk operations** now update the store once instead of N times (N = number of plugins in operation)
+- **No duplicate renders** from local state → store → local state sync cycle
+- **Memoized derivation** prevents unnecessary recomputation
+
+### Potential Concerns
+
+- None expected; `useMemo` derivation is O(n) where n = number of plugins
+- Store's `updatePlugins` already has JSON comparison optimization
+
+## Migration Notes
+
+- No data migration needed; store format unchanged
+- Existing persisted configs will work without changes
+

+# Proposal: A Layered Package System for Promptfoo
+
+## Executive Summary
+
+Promptfoo should move from "one published package that happens to contain many
+systems" to "one familiar full package backed by a small set of explicit package
+layers."
+
+The recommendation is:
+
+1. Keep `promptfoo` as the default full install and compatibility facade.
+2. Create private workspace packages first, then publish only the packages whose
+   boundaries prove useful.
+3. Separate the low-dependency evaluation kernel from Node adapters, CLI,
+   server/UI hosting, redteam, and provider families.
+4. Make dependency ownership visible and test the packed artifacts users install,
+   not only the source tree.
+5. Preserve dual ESM/CommonJS support at public package boundaries during the
+   transition.
+
+This gives lightweight consumers a smaller dependency graph without making the
+normal `npm install promptfoo` experience worse. It also gives the team a safer
+path to provider packs and future products without forcing a flag day.
+
+## Why Change
+
+Today, the published root package owns several quite different responsibilities:
+
+- Node library entrypoint
+- CLI
+- evaluation engine
+- database and migrations
+- sharing and persistence
+- view server
+- redteam workflows
+- many provider SDKs
+- the built web UI
+
+That makes the root package convenient, but also broad:
+
+- The root package currently has `83` direct runtime dependencies and `36`
+  optional dependencies.
+- Before this prototype, the public library entrypoint in `src/index.ts`
+  imported migrations, models, sharing, provider loading, and redteam APIs.
+  The prototype starts separating that shape by moving the public Node API
+  behind `src/node/evaluate.ts`, keeping the internal orchestration in the Node
+  layer at `src/evaluate.ts`, and carving a first leaf-safe contract subset into
+  `src/contracts/**` while `promptfoo` remains the facade.
+- `src/main.ts` and `src/commands/view.ts` are already outer-shell concerns,
+  not core evaluation concerns.
+- Provider loading is centralized enough that optional/provider dependencies are
+  still effectively part of the product shape.
+
+The system has grown past the point where one package boundary expresses the
+architecture well.
+
+## Non-Goals
+
+- Do not make existing users choose packages on day one.
+- Do not publish every internal boundary just because it exists.
+- Do not require a package-manager migration before the architecture improves.
+- Do not turn providers into runtime-installed plugins as a prerequisite for the
+  split.
+- Do not combine the package split with an ESM-only migration.
+
+## Design Principles
+
+1. **One obvious default.**
+   `promptfoo` remains the package most users install.
+
+2. **Narrow leaves, convenient facade.**
+   Lightweight consumers should not pay for servers, databases, CLIs, or provider
+   SDKs they do not use.
+
+3. **No runtime dependency magic.**
+   Dependency installation happens at install/build/publish time, not when an eval
+   starts or a server boots.
+
+4. **Private boundaries before public promises.**
+   We should first make internal ownership real inside the monorepo, then publish
+   only the packages that survive real use.
+
+5. **Dual-format correctness over format ideology.**
+   Promptfoo already supports both ESM and CommonJS. Public packages should keep
+   doing that until we intentionally decide otherwise.
+
+6. **Package artifacts are the contract.**
+   A source-tree green build is not enough; every published package must be packed,
+   installed, imported, required, and exercised as a user would consume it.
+
+## Recommended Package Topology
+
+```mermaid
+flowchart TD
+  schema["@promptfoo/schema"]
+  core["@promptfoo/core"]
+  node["@promptfoo/node"]
+  redteam["@promptfoo/redteam"]
+  providers["@promptfoo/provider-*"]
+  view["@promptfoo/view-server"]
+  cli["@promptfoo/cli"]
+  facade["promptfoo"]
+
+  schema --> core
+  core --> node
+  core --> redteam
+  core --> providers
+  node --> view
+  node --> cli
+  redteam --> cli
+  providers --> facade
+  node --> facade
+  redteam --> facade
+  view --> facade
+  cli --> facade
+```
+
+### `@promptfoo/schema`
+
+**Purpose**
+
+- Config types and runtime schemas
+- JSON schema generation
+- Browser-safe shared contracts
+- Stable serialized result shapes where appropriate
+
+**May depend on**
+
+- schema libraries such as `zod`
+
+**Must not depend on**
+
+- `fs`, `@libsql/client`, Express, provider SDKs, CLI libraries, server code
+
+**Why it exists**
+
+- It is the cleanest shared layer between library, CLI, server, UI, and docs.
+- It is also the safest first extraction.
+
+### `@promptfoo/core`
+
+**Purpose**
+
+- Pure evaluation domain model
+- Test planning, prompt expansion, assertions, scoring, result aggregation
+- Provider/assertion interfaces
+- No direct filesystem, DB, HTTP-server, or provider-SDK assumptions
+
+**May depend on**
+
+- `@promptfoo/schema`
+- small domain utilities
+
+**Must not depend on**
+
+- persistence
+- web server
+- CLI
+- concrete provider SDK packages
+
+**Why it exists**
+
+- This is the actual reusable engine people mean when they say "the Node package."
+- It should be possible to run it with fake providers and in-memory adapters.
+
+### `@promptfoo/node`
+
+**Purpose**
+
+- Node adapters around core
+- config/file loading
+- local persistence
+- migrations
+- cache
+- share/report persistence helpers
+- current `evaluate()`-style Node API
+
+**May depend on**
+
+- `@promptfoo/core`
+- `@promptfoo/schema`
+- Node-only dependencies such as `@libsql/client`, `glob`, `chokidar`, `dotenv`
+
+**Why it exists**
+
+- Most library users still want the batteries-included Node API.
+- This gives them that without forcing the same dependencies onto future
+  browser-safe or embedded consumers.
+
+### `@promptfoo/redteam`
+
+**Purpose**
+
+- redteam generation, strategies, graders, plugins, reporting
+
+**May depend on**
+
+- `@promptfoo/core`
+- `@promptfoo/node` only where it truly needs Node adapters
+- redteam-specific dependencies
+
+**Why it exists**
+
+- Redteam is now a substantial product surface with its own cadence,
+  dependencies, docs, and CLI flows.
+
+### `@promptfoo/view-server`
+
+**Purpose**
+
+- Express/socket server
+- API routes
+- static app serving
+- local UI hosting
+
+**May depend on**
+
+- `@promptfoo/node`
+- server-specific dependencies
+
+**Why it exists**
+
+- The server is useful, but it is not intrinsic to every library consumer.
+
+### `@promptfoo/cli`
+
+**Purpose**
+
+- command registration
+- process lifecycle
+- update checks
+- terminal UX
+- orchestration across `node`, `redteam`, and `view-server`
+
+**May depend on**
+
+- `@promptfoo/node`
+- `@promptfoo/redteam`
+- `@promptfoo/view-server`
+
+**Why it exists**
+
+- The CLI is a shell around the system, not the system itself.
+
+### `@promptfoo/provider-*`
+
+**Purpose**
+
+- Provider-specific implementations and SDK dependencies
+- Examples:
+  - `@promptfoo/provider-openai`
+  - `@promptfoo/provider-anthropic`
+  - `@promptfoo/provider-aws`
+  - `@promptfoo/provider-google`
+  - eventually a small `@promptfoo/providers-core` for zero-extra-dependency or
+    very common providers
+
+**May depend on**
+
+- `@promptfoo/core`
+- provider SDKs owned by that package
+
+**Why it exists**
+
+- This is where the largest optional dependency savings eventually come from.
+- It also makes provider ownership and release notes much clearer.
+
+**Important**
+
+- Do not start by publishing dozens of provider packages.
+- First make provider registration explicit and let built-in providers move behind
+  the same registry shape internally.
+
+### `promptfoo`
+
+**Purpose**
+
+- Familiar full package
+- current CLI binaries
+- compatibility imports
+- "everything included" experience
+
+**Behavior**
+
+- Depends on the packages that define the full Promptfoo distribution.
+- Re-exports the stable Node API from `@promptfoo/node`.
+- Continues to ship the CLI users know.
+- Becomes the migration shield while the rest of the topology matures.
+
+## Dependency Policy
+
+### Ownership Rule
+
+Every runtime dependency must have one declared owner:
+
+- core runtime
+- node runtime
+- cli runtime
+- view-server runtime
+- redteam runtime
+- provider runtime
+- docs/app/dev-only
+
+If a dependency is used by more than one package, we should prefer:
+
+1. a smaller shared package only when the shared code is real, or
+2. duplicate declarations when the runtime ownership is legitimately separate.
+
+Do not keep dependencies at the root merely because multiple packages happen to
+use them during the transition.
+
+### Boundary Rule
+
+- A package may import only from packages below it in the topology.
+- No package may deep-import another package's `src/**`.
+- Public imports go through explicit package exports.
+- UI code depends on schema/browser-safe contracts, not Node internals.
+
+### Provider Rule
+
+- Provider SDK dependencies belong to provider packages.
+- `core` knows only provider interfaces and registration metadata.
+- `node` may ship a default provider registry, but should not be the owner of every
+  provider SDK forever.
+
+### Optional Dependency Rule
+
+- Use `optionalDependencies` only for genuinely optional platform/native
+  capability, not as a substitute for package ownership.
+- Once a provider family has its own package, its SDK should leave the root
+  optional-dependency bucket.
+
+## Build and Repository Model
+
+### Keep npm Workspaces for the First Stage
+
+The repository already uses npm workspaces and has established CI around them.
+The split does not require an immediate package-manager migration.
+
+Recommended first-stage workspace layout:
+
+```text
+packages/
+  schema/
+  core/
+  node/
+  redteam/
+  view-server/
+  cli/
+  provider-openai/
+  provider-anthropic/
+src/app/
+site/
+```
+
+`src/` can migrate inward over time. During the first phase, thin package entry
+files may point at existing source while we move code by ownership.
+
+### Build Outputs
+
+Each publishable package should produce:
+
+```text
+dist/
+  esm/
+  cjs/
+  types/
+```
+
+and expose only supported entrypoints through `exports`.
+
+Recommended package export shape:
+
+```json
+{
+  "type": "module",
+  "exports": {
+    ".": {
+      "types": "./dist/types/index.d.ts",
+      "import": "./dist/esm/index.js",
+      "require": "./dist/cjs/index.cjs"
+    }
+  }
+}
+```
+
+For Node-targeted packages, TypeScript should be checked in `nodenext` mode so
+the compiler models Node's dual-format resolver. Browser/bundler packages can
+keep bundler-oriented settings where appropriate.
+
+### Package Boundary Checks
+
+Add CI checks for:
+
+- illegal cross-package imports
+- public-export drift
+- missing dependency declarations
+- duplicate accidental dependencies
+- root dependency ownership
+- packed-tarball contents
+- ESM import smoke
+- CommonJS require smoke
+- type-resolution smoke
+
+The strongest useful addition from the OpenClaw study is a generated dependency
+ownership report:
+
+```text
+dependency                owner                  direct users       transitive size
+@libsql/client             @promptfoo/node        node               ...
+express                    @promptfoo/view-server view-server        ...
+@anthropic-ai/sdk          provider-anthropic     provider package   ...
+```
+
+That report should fail CI when:
+
+- a dependency has no owner
+- a package imports a dependency it does not declare
+- a dependency owned by a leaf is still imported from a higher layer
+
+### What We Should Borrow From OpenClaw
+
+The useful lesson from OpenClaw is not "copy its exact repo layout." It is that
+dependency management gets simpler when ownership is explicit and package
+artifacts are tested like user-facing products.
+
+Adopt:
+
+- private workspaces as the first architectural boundary
+- leaf-package ownership of runtime dependencies
+- dependency ownership reports in CI
+- tarball checks and clean-install acceptance tests
+- install/update flows that are explicit, never hidden inside startup paths
+
+Do not adopt blindly:
+
+- an immediate package-manager migration
+- runtime-installable provider plugins before Promptfoo needs that product model
+- ESM-only publishing while Promptfoo still supports both `import` and `require`
+
+## Publishing Model
+
+### Recommendation: One Version Line at First
+
+Use a fixed-version monorepo release for the first public split:
+
+- all public `@promptfoo/*` packages share the same version
+- `promptfoo` depends on exact matching versions of internal public packages
+- release notes can still call out package-specific changes
+
+This is easier for users, support, and rollback while boundaries are still
+forming. Independent versions become worth revisiting only after package
+consumption patterns are stable.
+
+### Release Automation
+
+Keep release automation centralized and extend the current flow rather than
+inventing a second release system immediately:
+
+1. build all publishable packages
+2. run package-graph checks
+3. pack each package
+4. install packed artifacts into clean temp projects
+5. run ESM, CJS, CLI, server, and upgrade smokes
+6. publish with npm trusted publishing / provenance
+7. publish the `promptfoo` facade last
+
+Promptfoo already publishes with provenance in the current release workflow, so
+this should be an extension of the existing release path rather than a parallel
+system.
+
+### Artifact Acceptance
+
+Before publish, every public package should prove:
+
+- `npm pack` contents are complete
+- no source-only files are required at runtime
+- `import` works
+- `require` works
+- TypeScript resolves exported types
+- `promptfoo` facade still exposes current behavior
+- upgrade from the last published version works for the top-level package
+
+The current smoke-test philosophy already says "test the built package, not
+source code." This proposal extends that idea from the root package to every
+public package.
+
+## ESM and CommonJS Strategy
+
+Promptfoo should remain dual-mode during the split.
+
+### Rules
+
+- Public packages ship both `import` and `require` conditions until we make a
+  separate deprecation decision.
+- Source-of-truth implementation may remain ESM-first.
+- CJS builds are compatibility artifacts, not a second architecture.
+- No package may rely on unexported internal paths from another package.
+- Every public package gets both `import` and `require` smoke tests.
+
+### Why
+
+Modern Node can load more ESM from CommonJS than older Node versions could, but
+Promptfoo already promises a `require` entrypoint today. Keeping that promise
+while the package graph changes avoids combining two migrations into one.
+
+## Developer Experience
+
+The system should feel no worse locally than the repo does today.
+
+### Required Properties
+
+- one install at the repo root
+- one normal full build command
+- package-local test commands when working narrowly
+- no manual linking
+- no publishing knowledge required for ordinary feature work
+- docs/examples keep using `promptfoo` unless a smaller package is the point of
+  the example
+
+### Useful Commands
+
+```bash
+npm run build
+npm test
+npm run test:package -- --package @promptfoo/node
+npm run deps:ownership
+npm run pack:check
+```
+
+### Golden Path
+
+Most contributors should continue to:
+
+1. install once
+2. edit one package or normal source file
+3. run focused tests
+4. run the normal repo checks before merging
+
+Package boundaries should make reasoning easier, not force every engineer to
+become a release engineer.
+
+## Documentation System
+
+### New Docs to Add
+
+1. `docs/architecture/packages.md`
+   - package graph
+   - dependency rules
+   - when to add a package
+
+2. `docs/agents/package-development.md`
+   - how to choose the owning package
+   - package-boundary checks
+   - ESM/CJS export rules
+
+3. `site/docs/usage/packages.md`
+   - "which package should I install?"
+   - full package vs lightweight library vs provider packs
+
+4. Per-package README template
+   - purpose
+   - install
+   - supported imports
+   - dependency notes
+   - compatibility guarantees
+
+### Public Message
+
+For users, the story should be simple:
+
+- Install `promptfoo` when you want the normal product.
+- Install `@promptfoo/node` when you want the Node library without the CLI/server.
+- Install provider packages only when you want explicit fine-grained control.
+
+## Migration Plan
+
+### Phase 0: Add Guardrails Without Moving Code
+
+- add dependency ownership inventory
+- add package-artifact smoke harness
+- add package-boundary linting
+- add architecture docs
+
+**Exit criterion**
+
+- We can explain which dependency belongs to which future package.
+
+### Phase 1: Extract the Safest Layers Privately
+
+- create private workspaces for `schema`, `core`, and `node`
+- move exports and types behind those boundaries
+- keep `promptfoo` behavior unchanged
+
+**Exit criterion**
+
+- Existing CLI and Node consumers pass unchanged through the facade.
+
+### Phase 2: Split Outer Shells Privately
+
+- create private `cli` and `view-server`
+- move server dependencies out of node/core
+- move command orchestration out of the library layer
+
+**Exit criterion**
+
+- `@promptfoo/node` can build and test without CLI/server dependencies.
+
+### Phase 3: Make Provider Registration Explicit
+
+- define provider registration API
+- move a small pilot set behind provider packages internally
+- start with packages that have obvious heavy dependencies or ownership
+
+**Exit criterion**
+
+- Providers can be loaded through one registry path whether bundled or packaged.
+
+### Phase 4: Publish the First Useful Subpackages
+
+Recommended first public packages:
+
+1. `@promptfoo/schema`
+2. `@promptfoo/node`
+3. `@promptfoo/view-server`
+
+Keep `promptfoo` as the full facade.
+
+**Exit criterion**
+
+- Real users can consume the smaller packages without undocumented imports or
+  hidden dependencies.
+
+### Phase 5: Publish Provider Packs Selectively
+
+Only publish provider packages where there is a clear benefit:
+
+- large SDK footprint
+- unusual native/platform dependency
+- clear ownership
+- meaningful install-size reduction
+- independent release pressure
+
+**Exit criterion**
+
+- Provider packages reduce the root graph without making provider selection
+  confusing.
+
+## Alternatives Considered
+
+### A. Keep One Package Forever
+
+**Pros**
+
+- simplest publishing story
+- zero package churn
+
+**Cons**
+
+- dependency graph keeps growing
+- library consumers keep paying for unrelated surfaces
+- harder ownership and release reasoning
+
+### B. Split Everything Immediately
+
+**Pros**
+
+- cleanest theoretical end state
+
+**Cons**
+
+- too many public promises at once
+- high migration risk
+- poor signal about which boundaries users actually need
+
+### C. Recommended: Layered Split With a Facade
+
+**Pros**
+
+- gives smaller packages to users who need them
+- keeps today's default UX
+- makes ownership real before multiplying public APIs
+- lets us stop after any phase if the benefits flatten out
+
+**Cons**
+
+- a transitional period with some duplicated packaging work
+- requires disciplined export and dependency checks
+
+## Risks and Mitigations
+
+| Risk                                          | Mitigation                                                                      |
+| --------------------------------------------- | ------------------------------------------------------------------------------- |
+| Internal package churn leaks into public API  | Publish only after private boundary use stabilizes                              |
+| Dual ESM/CJS builds become inconsistent       | Artifact smokes for both import modes on every public package                   |
+| Developers slow down in a new monorepo layout | Keep root install/build/test commands as the golden path                        |
+| Provider package count becomes confusing      | Publish provider packs selectively; keep `promptfoo` full install               |
+| Version skew across packages                  | Start with fixed versions and exact internal deps                               |
+| Release workflow becomes fragile              | Reuse current release pipeline, add package-graph and tarball acceptance checks |
+
+## Decisions Requested
+
+1. Approve the layered topology as the target direction.
+2. Approve a private-workspace-first migration rather than immediate public
+   package proliferation.
+3. Approve `promptfoo` as the long-lived full facade.
+4. Approve fixed-version public packages for the first release cycle.
+5. Approve dual ESM/CommonJS support for all first-wave public packages.
+6. Approve investment in dependency ownership and package-acceptance CI before
+   publishing subpackages.
+
+## First Concrete Milestone
+
+The first milestone should be deliberately modest:
+
+1. Add dependency ownership reporting.
+2. Create private `packages/schema`, `packages/core`, and `packages/node`.
+3. Move the public Node API behind `@promptfoo/node` while keeping
+   `promptfoo` exports unchanged.
+4. Prove that `@promptfoo/node` can build and test without CLI/server imports.
+5. Add packed-artifact smoke tests for the root package and the private node
+   package.
+
+If that milestone is not useful, we learn cheaply. If it is useful, the rest of
+the package system has a clear path.
+
+## Appendix: Current-Code Signals
+
+- Before this prototype, `src/index.ts` mixed the Node API with migrations,
+  sharing, provider loading, and redteam exports. The prototype moves the Node
+  orchestration into `src/node/evaluate.ts` as the first concrete seam.
+- `src/main.ts` is already a CLI shell around lower-level functionality.
+- `src/commands/view.ts` and `src/server/**` are natural `view-server` owners.
+- `src/providers/**` is already a natural future provider-package boundary.
+- `src/types/index.ts` is already being deconstructed, which points toward
+  `schema` as a first extraction.
+
+## Appendix: 2026 Packaging Notes
+
+- Use explicit `exports` maps for public packages.
+- For Node-targeted packages, type-check in `nodenext` mode so TypeScript models
+  the same `import`/`require` behavior Node uses.
+- Keep npm trusted publishing / provenance in the release path for every public
+  package.
+- Treat `npm pack` plus clean-install smoke tests as the release contract, not an
+  optional extra.

+# Plan: `promptfoo eval -c <uuid>` Cloud Config Support
+
+## Context
+
+Currently, `promptfoo redteam run -c <uuid>` supports loading configs from Promptfoo Cloud by UUID, but `promptfoo eval -c` only accepts local file paths. This feature extends the same cloud config loading pattern to the eval command, allowing users to run `promptfoo eval -c <cloud-uuid>` to fetch and execute a config stored in Promptfoo Cloud.
+
+The ticket (ENG-1770) has two parts:
+
+1. **Open Source (this PR)**: Make the CLI accept a cloud UUID for `eval -c`
+2. **Cloud**: Show the `promptfoo eval -c <uuid>` command in the Cloud run modal (separate repo)
+
+## Changes
+
+### 1. Add `getEvalConfigFromCloud()` to `src/util/cloud.ts`
+
+Create a new function modeled after the existing `getConfigFromCloud()` (line 88-114) but hitting a different endpoint for eval configs:
+
+```typescript
+export async function getEvalConfigFromCloud(id: string): Promise<UnifiedConfig> {
+  // Same pattern as getConfigFromCloud but using `configs/${id}` endpoint
+}
+```
+
+- Endpoint: `GET /api/v1/configs/${id}` (eval configs, not redteam-specific)
+- Reuse existing `makeRequest()` helper (line 25) and `cloudConfig.isEnabled()` check pattern
+- Same error handling pattern as `getConfigFromCloud`
+
+### 2. Add UUID detection to `src/commands/eval.ts`
+
+In `doEval()` (line 107), add UUID detection **before** the existing config path processing at line 142. This mirrors the pattern in `src/redteam/commands/run.ts:62-79`.
+
+```typescript
+// Before the existing config path processing (line 142)
+const UUID_REGEX = /^[A-Fa-f0-9]{8}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{12}$/;
+
+if (cmdObj.config?.length === 1 && UUID_REGEX.test(cmdObj.config[0])) {
+  const cloudConfigObj = await getEvalConfigFromCloud(cmdObj.config[0]);
+  defaultConfig = cloudConfigObj;
+  cmdObj.config = undefined;
+}
+```
+
+Key behaviors:
+
+- Only trigger when exactly one config path is provided and it's a UUID
+- Fetch the config from cloud and use it as `defaultConfig`
+- Clear `cmdObj.config` so `resolveConfigs` uses `defaultConfig` instead of trying to read a file
+- Import `getEvalConfigFromCloud` from `../../util/cloud`
+
+### 3. Update eval command description
+
+Update the `-c` option description at line 903-906 to mention cloud UUID support:
+
+```typescript
+.option(
+  '-c, --config <paths...>',
+  'Path to configuration file or cloud config UUID. Automatically loads promptfooconfig.yaml',
+)
+```
+
+### 4. Add tests
+
+Create test cases in a new test file or add to existing eval command tests, following the pattern from `test/redteam/commands/run.test.ts`:
+
+- Test UUID detection triggers cloud fetch
+- Test local file paths bypass UUID detection
+- Test error when cloud is not enabled
+- Test multiple config paths with UUID (should not trigger UUID detection)
+
+## Files to Modify
+
+| File                                          | Change                                                                  |
+| --------------------------------------------- | ----------------------------------------------------------------------- |
+| `src/util/cloud.ts`                           | Add `getEvalConfigFromCloud()` function                                 |
+| `src/commands/eval.ts`                        | Add UUID detection + cloud fetch in `doEval()`, update `-c` description |
+| `test/commands/eval.test.ts` or new test file | Add tests for UUID cloud config                                         |
+
+## Existing Code to Reuse
+
+- `makeRequest()` from `src/util/cloud.ts:25` - authenticated HTTP helper
+- `cloudConfig.isEnabled()` from `src/globalConfig/cloud.ts` - auth check
+- UUID regex pattern from `src/redteam/commands/run.ts:17`
+- `resolveConfigs()` from `src/util/config/load.ts:481` - existing config resolution (no changes needed)
+
+## Verification
+
+1. **Build**: `npm run build` should succeed
+2. **Lint**: `npm run l && npm run f`
+3. **Unit tests**: Run existing + new tests with `npx vitest src/commands/eval` and `npx vitest src/util/cloud`
+4. **Manual test** (if cloud access available):
+   - `npm run local -- eval -c <valid-uuid> --env-file .env` should fetch config from cloud
+   - `npm run local -- eval -c path/to/config.yaml` should still work as before
+   - `npm run local -- eval -c <invalid-uuid-format>` should fall through to file resolution
+
+## Decisions (Reconciled)
+
+1. Use the OSS endpoint contract: `GET /api/v1/configs/:id` returning an envelope (`{ config: ... }`), not a raw payload.
+2. Support persisted config shape with `providers` and `tests`; loading must not require additional requests.
+3. Provider references in the config should use `promptfoo://provider/<uuid>`.
+4. Prompts should be emitted as plain strings.
+5. `tests` defaults to `[]` when missing.
+6. `description` falls back to `config.name` when missing.
+7. `--watch` is not supported when `-c <uuid>` is used. CLI should fail fast with a clear error.
+8. If `-c <value>` matches UUID format but cloud fetch fails (404/auth disabled), hard-fail.
+9. If multiple `-c` values are supplied and any value is a UUID, fail with an explicit error stating only one `-c` value is allowed for cloud UUID mode.
+10. Add tests in both places:
+    - `test/commands/eval.test.ts` for UUID detection/CLI behavior
+    - `test/util/cloud.test.ts` for `getEvalConfigFromCloud()` contract/error handling
+11. Scope is `eval` only (not `redteam eval`).
+12. No temporary UI note or minimum-version gating is required.
+13. In UUID mode, clear/ignore `defaultConfigPath` for the run to prevent accidental local reload/fallback behavior.
+14. Read-time schema normalization should normalize legacy fields (`providerIds`/`testCases`) into canonical fields (`providers`/`tests`).
+
+### CLI Error Messages (exact draft text)
+
+1. Multiple `-c` values with UUID mode:
+   - `Cloud config UUID mode supports exactly one -c value. Use: promptfoo eval -c <cloud-config-uuid>`
+2. UUID mode with `--watch`:
+   - `--watch is not supported when using a cloud config UUID with -c. Use a local config file path for watch mode.`
+3. UUID-shaped value with failed cloud fetch:
+   - `Failed to load cloud eval config "<uuid>". <reason>. Cloud UUID inputs do not fall back to local file paths. Check authentication and that the UUID exists.`
+
+## Remaining Follow-ups
+
+None.

+# Adaptive Rate Limit Scheduler - Architecture
+
+## Overview
+
+The adaptive rate limit scheduler automatically handles provider rate limits during evaluations. It's **zero-configuration** - users don't need to change anything. The scheduler transparently wraps all provider calls with intelligent rate limit detection, retry logic, and adaptive concurrency management.
+
+## Design Goals
+
+The scheduler addresses common challenges when running evaluations against rate-limited APIs:
+
+- **No manual tuning**: Users shouldn't need to guess the right `-j` (concurrency) value
+- **Automatic recovery**: Rate limit errors (429) should be retried, not fail permanently
+- **Prevent cascading failures**: High concurrency shouldn't cause mass failures
+- **Zero configuration**: Works out of the box with sensible defaults
+

+## Component Responsibilities
+
+### RateLimitRegistry
+
+**File**: `src/scheduler/rateLimitRegistry.ts`
+
+Central coordinator that:
+
+- Creates/retrieves per-provider state based on rate limit keys
+- Routes provider calls to the appropriate state
+- Aggregates metrics across all providers
+- Emits events for monitoring
+
+```typescript
+// Usage (automatic in evaluator)
+const result = await registry.execute(provider, () => provider.callApi(...), {
+  getHeaders: (result) => result.metadata?.headers,
+  isRateLimited: (result, error) => error?.message?.includes('429'),
+  getRetryAfter: (result, error) => parseRetryAfter(headers['retry-after']),
+});
+```
+
+### ProviderRateLimitState
+
+**File**: `src/scheduler/providerRateLimitState.ts`
+
+Per-provider state manager that:
+
+- Manages the slot queue for concurrency control
+- Tracks rate limit headers from responses
+- Implements retry logic with exponential backoff
+- Adapts concurrency based on success/failure patterns
+- Collects latency metrics
+
+### SlotQueue
+
+**File**: `src/scheduler/slotQueue.ts`
+
+FIFO queue with concurrency limiting:
+
+- Acquires/releases "slots" for concurrent requests
+- Blocks when at max concurrency or quota exhausted
+- Tracks remaining requests/tokens from headers
+- Schedules queue processing after rate limit windows
+
+Key insight: **Race-condition-free** slot allocation. All requests queue, then slots are allocated in FIFO order.
+
+### AdaptiveConcurrency
+
+**File**: `src/scheduler/adaptiveConcurrency.ts`
+
+Dynamic concurrency adjustment:
+
+- **On rate limit**: Reduce concurrency by 50% (multiplicative decrease)
+- **On sustained success**: Increase by 1 (additive increase)
+- **Proactive throttling**: Reduce when approaching limits (via headers)
+
+This implements AIMD (Additive Increase, Multiplicative Decrease) - the same algorithm TCP uses for congestion control.
+
+### HeaderParser
+
+**File**: `src/scheduler/headerParser.ts`
+
+Parses rate limit headers from multiple providers:
+
+- **OpenAI**: `x-ratelimit-remaining-requests`, `x-ratelimit-limit-requests`
+- **Anthropic**: `anthropic-ratelimit-requests-remaining`
+- **Generic**: `retry-after`, `retry-after-ms`, `ratelimit-reset`
+
+### RetryPolicy
+
+**File**: `src/scheduler/retryPolicy.ts`
+
+Determines retry behavior:
+
+- Exponential backoff with jitter
+- Respects server `retry-after` headers
+- Configurable max retries (default: 3)
+- Retries on: rate limits, timeouts, 502/503/504
+
+## Data Flow
+
+```text
+1. Evaluator calls registry.execute(provider, callFn)
+       │
+       ▼
+2. Registry gets/creates ProviderRateLimitState for this provider
+       │
+       ▼
+3. State.executeWithRetry() is called
+       │
+       ▼
+4. SlotQueue.acquire() - wait for available slot
+       │
+       ▼
+5. Execute callFn() - actual provider API call
+       │
+       ▼
+6. Parse response headers → update rate limit state
+       │
+       ▼
+7. Check if rate limited:
+   ├─ Yes → retry with backoff, reduce concurrency
+   └─ No  → record success, maybe increase concurrency
+       │
+       ▼
+8. SlotQueue.release() - free slot for next request
+       │
+       ▼
+9. Return result (or throw after max retries)
+```
+
+## Rate Limit Key Generation
+
+Each provider gets a unique "rate limit key" based on:
+
+- Provider ID (e.g., "openai:chat:gpt-4o")
+- API key hash (different keys = different rate limits)
+- Organization ID (if applicable)
+
+This ensures:
+
+- Same provider + same key = shared rate limit state
+- Same provider + different keys = separate rate limits
+- Different providers = completely isolated
+
+## Key Design Decisions
+
+### 1. Zero Configuration
+
+Users shouldn't need to tune rate limit settings. The scheduler learns from response headers and adapts automatically.
+
+### 2. Fail-Safe Defaults
+
+- Default max concurrency: 4 (conservative)
+- Default retry delay: 60 seconds (when no header)
+- Max retries: 3 (prevents infinite loops)
+
+### 3. Proactive Throttling
+
+Don't wait for 429 errors. When headers show <10% remaining quota, proactively reduce concurrency.
+
+### 4. Per-Provider Isolation
+
+Different providers have different rate limits. Don't let OpenAI rate limits affect Anthropic calls.
+
+### 5. Transparent Integration
+
+The scheduler wraps `provider.callApi()` without changing the interface. Existing code works unchanged.
+
+## Metrics
+
+The scheduler tracks:
+
+- `totalRequests` - All requests attempted
+- `completedRequests` - Successful completions
+- `failedRequests` - Permanent failures (after retries)
+- `rateLimitHits` - Times 429 was encountered
+- `retriedRequests` - Requests that required retry
+- `avgLatencyMs`, `p50LatencyMs`, `p99LatencyMs` - Latency distribution
+
+## Events
+
+For monitoring/debugging, the scheduler emits:
+
+- `slot:acquired` / `slot:released` - Concurrency tracking
+- `ratelimit:hit` - Rate limit encountered
+- `ratelimit:learned` - First time seeing provider's limits
+- `ratelimit:warning` - Approaching rate limit
+- `concurrency:increased` / `concurrency:decreased` - Adaptive changes
+- `request:retrying` - Retry in progress
+
+## Testing
+
+256 tests covering:
+
+- Unit tests for each component
+- Edge cases (negative values, zero values, overflow)
+- Race condition prevention
+- Integration with evaluator
+
+## Performance Characteristics
+
+- **Overhead**: Minimal - just slot acquisition and header parsing
+- **Memory**: O(providers) - one state object per unique rate limit key
+- **Latency buffer**: Circular buffer, last 100 requests, O(1) insertion
