   - Add Jest configuration for JavaScript/TypeScript

---

## 3. Educational Enhancements

### 3.1 New Lesson Topics

1. **Security in AI Applications** (Proposed Lesson 22)
   - Prompt injection attacks and defenses
   - API key management
   - Content moderation
   - Rate limiting and abuse prevention

| 11 - Function Calling | Add parallel function calling |
| 15 - RAG | Add chunking strategy comparison |
| 17 - AI Agents | Add multi-agent orchestration |

---

## 4. API Modernization

### 4.1 Deprecated API Patterns (Migration Completed)

All Python and TypeScript **chat** samples have been migrated from the Chat Completions API to the **Responses API** (`client.responses.create(...)` → `response.output_text`).

| Old Pattern | New Pattern | Status |
|-------------|-------------|--------|
| `openai.api_type = "azure"` / `AzureOpenAI()` (chat) | `OpenAI(base_url="<endpoint>/openai/v1/")` (Responses API) | Completed |
| `openai.ChatCompletion.create()` / `client.chat.completions.create()` | `client.responses.create(input=...)` → `response.output_text` | Completed |
| `@azure/openai` `OpenAIClient.getChatCompletions()` (TypeScript) | `openai` package `client.responses.create()` → `response.output_text` | Completed |
| `df.append()` (pandas) | `pd.concat()` | Completed |

> **Note:** Microsoft Foundry Models samples that use the `azure-ai-inference` / `@azure-rest/ai-inference` SDK (`client.complete()`) remain on the Model Inference API, which does not support the Responses API. `AzureOpenAI()` is intentionally retained where still valid (embeddings and image generation).

### 4.2 New API Features to Demonstrate

1. **Structured Outputs** (OpenAI)
   - JSON mode
   - Function calling with strict schemas

2. **Vision Capabilities**
   - Image analysis with GPT-4o (vision)
   - Multi-modal prompts

3. **Responses API Built-in Tools** (supersedes the legacy Assistants API)
   - Code interpreter
   - File search
   - Web search and custom tools

---

## 5. Infrastructure Improvements

### 5.1 CI/CD Enhancements

Implemented in [`.github/workflows/code-quality.yml`](../.github/workflows/code-quality.yml): Python linting/formatting (Ruff + Black) is **enforced** on the maintained `shared/` utilities module and runs **advisory** across the rest of the curriculum, plus an advisory ESLint pass for JavaScript/TypeScript. The illustrative baseline was:

```yaml
# .github/workflows/code-quality.yml
name: Code Quality

on: [push, pull_request]

jobs:
  python-lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: '3.10'
      - run: pip install ruff black mypy
      - run: ruff check .
      - run: black --check .

  js-lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
      - run: npm ci
      - run: npx eslint .
```

### 5.2 Security Scanning

Implemented in [`.github/workflows/security.yml`](../.github/workflows/security.yml): CodeQL analysis for Python and JavaScript/TypeScript (on push, pull request, and a weekly schedule) plus a dependency review on pull requests. The illustrative baseline was:

```yaml
# .github/workflows/security.yml
name: Security Scan

on: [push, pull_request]

jobs:
  codeql:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: github/codeql-action/init@v3
        with:
          languages: javascript, python
      - uses: github/codeql-action/analyze@v3

  dependency-review:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/dependency-review-action@v4
```

---

## 6. Developer Experience Improvements

### 6.1 DevContainer Enhancements

Implemented in [`.devcontainer/devcontainer.json`](../.devcontainer/devcontainer.json) and [`.devcontainer/post-create.sh`](../.devcontainer/post-create.sh): the container now ships Pylance, the Black formatter, Ruff, ESLint, Prettier, and Copilot extensions, enables format-on-save wired to the repo's Black/Prettier config, and installs the developer tooling (`ruff`, `black`, `mypy`, `pytest`) so the [code-quality workflow](../.github/workflows/code-quality.yml) can be reproduced locally. The `mcr.microsoft.com/devcontainers/universal` base image already bundles Python and Node, so no extra features are required. The illustrative baseline was:

```json
{
  "name": "Generative AI for Beginners",
  "image": "mcr.microsoft.com/devcontainers/universal:2",
  "features": {
    "ghcr.io/devcontainers/features/python:1": {
      "version": "3.11"
    },
    "ghcr.io/devcontainers/features/node:1": {
      "version": "20"
    }
  },
  "customizations": {
    "vscode": {
      "extensions": [
        "ms-python.python",
        "ms-python.vscode-pylance",
        "ms-toolsai.jupyter",
        "dbaeumer.vscode-eslint",
        "esbenp.prettier-vscode",
        "github.copilot"
      ],
      "settings": {
        "python.formatting.provider": "black",
        "editor.formatOnSave": true
      }
    }
  },
  "postCreateCommand": "pip install -e .[dev] && npm install"
}
```

### 6.2 Interactive Playground

Consider adding:
- Jupyter notebooks with pre-filled API keys (via environment)
- Gradio/Streamlit demos for visual learners
- Interactive quizzes for knowledge assessment

## 9. Accessibility and Internationalization

### 9.1 Current Translation Status

All translations are **complete** and generated automatically by the [Azure Co-op Translator](https://github.com/Azure/co-op-translator?WT.mc_id=academic-105485-koreyst), which produces and keeps 50+ language versions of the curriculum in sync with the English source. Translated content lives under `translations/` and localized images under `translated_images/`; the full list of available languages is published at the top of the repository README.

| Aspect | Status |
|--------|--------|
| Translation coverage | Complete — 50+ languages, all lessons |
| Translation method | Automated via [Azure Co-op Translator](https://github.com/Azure/co-op-translator?WT.mc_id=academic-105485-koreyst) |
| Kept in sync with English source | Yes — regenerated automatically |

### 9.2 Accessibility Improvements

1. Add alt text to all images
2. Ensure code samples have proper syntax highlighting
3. Add video transcripts for all video content
4. Ensure color contrast meets WCAG guidelines
