-# Durable backbone for the autonomous improvement loop
-# (see internal/docs/CONTINUOUS_IMPROVEMENT.md).
-#
-# A Claude Max subscription provides no API key for CI, so the loop is driven by
-# Codex rather than Claude Code: on a cadence this opens a fresh tracking issue and
-# posts an @codex instruction on it, and Codex runs one improvement increment + opens
-# a PR. (See the per-issue rationale below.)
-#
-# Codex does NOT respond to comments authored by the github-actions bot, so the
-# dispatch is GATED on a CODEX_TRIGGER_TOKEN secret (a PAT for a user account Codex
-# follows). Until that secret is set the workflow runs but no-ops — this avoids
-# piling up @codex comments that Codex silently ignores. The moment the secret is
-# added the loop activates with no further change.
-#
-# Each run opens a FRESH issue and dispatches Codex there, rather than re-commenting
-# on one tracker issue. Codex derives its PR branch name from the triggering issue's
-# context, so repeated dispatches on a single issue all collapse onto one branch name
-# (codex/github-mention-<that-issue-slug>) — the first increment opens a PR, the rest
-# collide on the occupied branch and silently fail to open one. A unique issue per
-# run gives each increment its own branch and a clean PR. The dispatch asks Codex to
-# "Closes #<issue>" so each tracking issue auto-closes when its PR merges.

-These instructions apply to the entire repository.
-
-## Pull requests from Codex tasks
-
-When a Codex task makes repository changes and the requested outcome is a PR:
-
-1. Keep the change focused on the assigned issue or prompt.
-2. Run the relevant verification commands and capture their results.
-3. Check `git status --short` and review the diff before finishing.
-4. Stage the intended files and create a local git commit on the current branch.
-5. Use the Codex `make_pr` tool to open the pull request with a concise title and a body that summarizes the change and testing.
-
-Do not just say that a PR was opened. If local changes exist, the task is not complete until the changes are committed and the `make_pr` tool has been called. A GitHub token in the shell environment is not a substitute for the Codex `make_pr` tool in this environment.

-# Changelog
-
-All notable changes to Go Micro are documented here.
-
-Format follows [Keep a Changelog](https://keepachangelog.com/). Go Micro uses
-calendar-based versions (YYYY.MM) for the AI-native era.
-
----
-
-## [6.0.0] - June 2026
-
-The AI-native major release. Breaking changes are listed first; everything
-else is additive. See the [v5 → v6 migration guide](internal/website/docs/guides/migration/v5-to-v6.md) — it's a small upgrade.
-
-### Changed (breaking)
-- **Module path is now `go-micro.dev/v6`.** Update imports (`go-micro.dev/v5/...` → `go-micro.dev/v6/...`) and `go install go-micro.dev/v6/cmd/micro@v6`.
-- **TLS verification is on by default.** v5 skipped verification unless `MICRO_TLS_SECURE=true`; v6 verifies by default. `MICRO_TLS_SECURE` is removed — set `MICRO_TLS_INSECURE=true` (or call `tls.InsecureConfig()`) for self-signed/dev certs.
-- **`micro.NewService(name, opts...)` is the service constructor**, symmetric with `NewAgent`/`NewFlow`. `micro.New(name, opts...)` remains as a deprecated alias; the old name-less `micro.NewService(opts...)` form is removed (pass the name positionally). Generators emit the new form.
-- **JWT auth ported in-module.** The external `github.com/micro/plugins/v5/auth/jwt` (pinned to v5) is replaced by `go-micro.dev/v6/auth/jwt/token`, now on the maintained `golang-jwt/jwt/v5`; the deprecated `dgrijalva/jwt-go` dependency is dropped.
-
-### Added
-- **A2A protocol — both directions** — `gateway/a2a` exposes registered agents over the open Agent2Agent (A2A) protocol so agents on other frameworks can discover and call them: Agent Cards are generated from registry metadata (the same way the MCP gateway derives tools), and incoming tasks are translated to the agent's existing `Agent.Chat` RPC, with no per-agent code (`micro a2a serve`). The outbound `a2a.Client` calls external A2A agents by URL, wired into `flow.A2A(url)` (a workflow step) and `delegate` to an `http(s)` URL (from inside an agent). An agent can also serve A2A **directly** without a gateway via `AgentA2A(addr)` (`a2a.NewAgentHandler`), handling tasks in-process. v1 is the synchronous JSON-RPC binding (`message/send`, `tasks/get`, card discovery); streaming and push notifications are advertised as unsupported. (`gateway/a2a/`, `cmd/micro/a2a/`)
-- **Agents (`micro.NewAgent`)** — an agent is a service with an LLM inside: it discovers its assigned services as tools, runs the model's tool loop, registers a `Chat` RPC endpoint, and is reachable like any service. `Ask` for programmatic use; `micro chat` discovers and routes to agents; `micro agent list`/`describe`. (`agent/`)
-- **Plan & delegate** — two built-in agent tools added to every agent: `plan` (an ordered, store-persisted plan surfaced back in the prompt) and `delegate` (hand a self-contained subtask to a registered agent over RPC, otherwise to an ephemeral sub-agent). No harness or graph — they're plain tools. (`agent/builtin.go`, `examples/agent-plan-delegate/`)
-- **Agent guardrails** — `MaxSteps` (stop on count), `LoopLimit` (stop repeated no-progress calls; on by default), and `ApproveTool` (human-in-the-loop / policy gate before each action), enforced at the one point every tool call passes through. (`agent/`, guide + blog)
-- **Pluggable agent memory & custom tools** — durable store-backed conversation memory by default, swappable via `AgentMemory`; register any function as a tool with `AgentTool`.
-- **Workflows (`micro.NewFlow`)** — event-driven orchestration that maps to Anthropic's workflow/agent split: an event triggers a deterministic step (or ordered durable steps), or dispatches to an agent with `FlowAgent`. (`flow/`)
-- **Flow loops (`FlowLoop`)** — a flow step that runs a body step repeatedly, carrying state across passes, until a stop condition is met or a hard iteration cap is hit. Stop on a code-defined predicate (`FlowUntil`) or let the model judge it done (`FlowUntilLLM` — the supervised "Ralph" loop); `FlowLoopMax` is the guardrail that guarantees termination, and `FlowOnIteration` reports progress. (`flow/loop.go`, `examples/flow-loop/`, guide)
-- **x402 payments** — opt-in per-call payments for tools via the x402 standard, with a pluggable facilitator and a consumer-side client + budget; the MCP gateway can advertise and require payment per tool. (`wrapper/x402/`, guide + blog)
-- **Scoped store state** — `store.Scope(s, database, table)` returns a store handle that confines every operation to a database/table without mutating the shared store (unlike `Init(Table(...))`, which is process-global and races between co-located components). Services, agents, and flows now each keep their state in their own table (`service/{name}`, `agent/{name}`, `flow/{name}`); the service path replaces the old `Init(store.Table(name))` global mutation with a scoped handle.
-- **Flow discovery & history CLI** — running flows now register in the registry as `type=flow` (and deregister on `Stop`), so they're discoverable like agents: `micro flow list` shows running flows, `micro flow runs <name>` shows a flow's durable run history from the store, and `micro agent history <name>` shows an agent's stored conversation. Live state comes from the registry; durable history from the scoped store.
-- **Durable workflows** — a flow can now be an ordered list of steps (a task with stages) that is checkpointed before and after each step, so a run survives a crash and resumes where it stopped without re-running completed steps. State carries a typed payload plus a `Stage` marker; flow-level `Retry` with a per-step override; runs retained for audit unless `DeleteOnSuccess`. Step actions: `Call` (RPC), `LLM` (model turn), `Dispatch` (to an agent), or any `StepFunc`. Durability is a pluggable `Checkpoint` (store-backed by default; implement the interface for Temporal/Restate). Runnable example: `examples/flow-durable/`. Blog: "Durable Workflows" (`internal/website/blog/24.md`).
-- **Agent tool-execution wrappers** — `AgentWrapTool` registers middleware around an agent's tool calls, the tool-side analogue of `client.CallWrapper`/`server.HandlerWrapper`. Use it for logging, metrics, retries, or policy; wrappers compose outermost-first and run outside the built-in guardrails. Includes a runnable example with observe + retry wrappers (`examples/agent-wrap-tool/`).
-- **Agent platform showcase** — full platform example (Users, Posts, Comments, Mail) mirroring [micro/blog](https://github.com/micro/blog), demonstrating how existing microservices become agent-accessible with zero code changes (`examples/mcp/platform/`).
-- **Blog post: "Your Microservices Are Already an AI Platform"** — walkthrough of agent-service interaction patterns using real-world services (`internal/website/blog/7.md`).
-- **Circuit breakers for MCP gateway** — per-tool circuit breakers protect downstream services from cascading failures. Configurable max failures, open-state timeout, and half-open probing. Available via `Options.CircuitBreaker` and `--circuit-breaker` CLI flag (`gateway/mcp/circuitbreaker.go`).
-- **Helm chart for MCP gateway** — official Helm chart at `deploy/helm/mcp-gateway/` with Deployment, Service, ServiceAccount, HPA, and Ingress templates. Supports Consul/etcd/mDNS registries, JWT auth, rate limiting, audit logging, per-tool scopes, TLS ingress, and auto-scaling.
-- **MCP gateway benchmarks** — comprehensive benchmark suite for tool listing, lookup, auth, rate limiting, and JSON serialization (`gateway/mcp/benchmark_test.go`)
-- **Workflow example** — cross-service orchestration demo with Inventory, Orders, and Notifications services showing agents chaining multi-step workflows from natural language (`examples/mcp/workflow/`)
-- **Docker Compose deployment** — production-like setup with Consul registry, standalone MCP gateway, and Jaeger tracing in one `docker-compose up` (`examples/deployment/`)

-## [2026.03] - March 2026
-
-### Added
-
-#### Developer Experience
-- **`micro new` MCP templates** — `micro new myservice` generates MCP-enabled services with doc comments, `@example` tags, and `WithMCP()` wired in. Use `--no-mcp` to opt out.
-- **`micro.NewService("name")` unified API** — single way to create services: `micro.NewService("greeter")` or `micro.NewService("greeter", micro.Address(":8080"))`. Replaces `micro.NewService()` + `service.New()` dual API.
-- **`service.Handle()` simplified registration** — register handlers with `service.Handle(new(Greeter))` instead of manual `server.NewHandler` + `server.Handle`.
-- **`micro.NewGroup()` modular monoliths** — run multiple services in one binary with shared lifecycle: `micro.NewGroup(users, orders).Run()`.
-- **`mcp.WithMCP()` one-liner** — add MCP to any service with a single option: `micro.NewService("name", mcp.WithMCP(":3001"))`.
-- **CRUD example** — contact book service with 6 operations, rich agent docs, and validation patterns (`examples/mcp/crud/`).

-- **OpenTelemetry integration** — full span instrumentation across HTTP, stdio, and WebSocket transports with W3C trace context propagation (`gateway/mcp/otel.go`).
-- **Standalone gateway binary** — `micro-mcp-gateway` with Docker support for running the MCP gateway independently of services.
-- **Per-tool auth scopes** — service-level (`server.WithEndpointScopes()`) and gateway-level (`Options.Scopes`) scope enforcement with bearer token auth.
-- **Rate limiting** — per-tool token bucket rate limiting (`Options.RateLimit`).
-- **Audit logging** — immutable audit records per tool call with trace ID, account, scopes, duration, and errors (`Options.AuditFunc`).
-
-#### AI Model Package
-- **`model.Model` interface** — unified AI provider abstraction with `Generate()` and `Stream()` methods.
-- **Anthropic Claude provider** — `model/anthropic` with tool execution and auto-calling.

-
-### Changed
-- Service interface moved to `service.Service` with `micro.Service` as a type alias for backward compatibility.
-- `service.New()` returns `service.Service` interface (was `*ServiceImpl`).
-- `service.NewGroup()` accepts `service.Service` interface (was `*ServiceImpl`).
-- `go.mod` template in `micro new` updated to Go 1.22.
-
-### Fixed
-- Handler `Handle()` method accepts variadic `server.HandlerOption` for scopes and metadata.
-- Store initialization uses service name as table automatically.
-- Service `Stop()` properly aggregates errors from lifecycle hooks.

-# CLAUDE.md - Go Micro Project Guide
-
-## Project Overview
-
-Go Micro is a framework for distributed systems development in Go. It provides pluggable abstractions for service discovery, RPC, pub/sub, config, auth, storage, and more.
-
-The framework is evolving into an **AI-native platform** where every microservice is automatically accessible to AI agents via the Model Context Protocol (MCP).
-
-## Build & Test
-
-```bash
-# Run all tests
-make test
-
-# Run tests for a specific package
-go test ./gateway/mcp/...
-go test ./ai/...
-go test ./model/...
-
-# Lint
-make lint
-
-# Format
-make fmt
-
-# Build CLI
-go build -o micro ./cmd/micro
-
-# Run locally with hot reload
-micro run
-```

-
-## Key Architectural Decisions
-
-- **Plugin architecture**: All abstractions use Go interfaces. Defaults work out of the box, everything is swappable.
-- **Progressive complexity**: Zero-config for development, full control for production.
-- **AI-native by default**: Every service is automatically an MCP tool. No extra code needed.
-- **In-repo plugins**: Plugins live in the main repo to avoid version compatibility issues.
-- **Reflection-based registration**: Handlers are registered via reflection for minimal boilerplate.
-
-## Code Conventions
-
-- Standard Go conventions (gofmt, golint)
-- Functional options pattern for configuration (`WithX()` functions)
-- Interface-first design: define the interface, then implement
-- Tests alongside code (not in separate test directories)
-- Commit messages: imperative mood, concise summary line
-
-## Current Focus & Priorities (March 2026)
-
-### Status
-- **Q1 2026 (MCP Foundation):** COMPLETE
-- **Q2 2026 (Agent DX):** COMPLETE (100%)
-- **Q3 2026 (Production):** 50% complete (ahead of schedule)
-
-### Priority 1: Agent Showcase & Examples
-Build compelling demos showing agents interacting with go-micro services in realistic scenarios.
-
-### Priority 2: Additional Protocol Support
-- gRPC reflection-based MCP
-- HTTP/3 support
-
-### Priority 3: Kubernetes & Deployment
-- Helm Charts for MCP gateway
-- Kubernetes Operator with CRDs
-
-### Recently Completed
-- **Agent Plan & Delegate** - Two built-in agent tools: `plan` (ordered plan persisted to store-backed memory, surfaced in the prompt) and `delegate` (hand a subtask to another agent — RPC to a registered agent, else an ephemeral sub-agent with isolated context). Added automatically to every agent; no harness or graph. (`agent/builtin.go`, `examples/agent-plan-delegate/`)
-- **`micro new` MCP Templates** - Scaffolds MCP-enabled services with doc comments, `@example` tags, `WithMCP()`. `--no-mcp` to opt out.
-- **CRUD Example** - Contact book service with 6 operations, rich agent docs (`examples/mcp/crud/`)
-- **Migration Guide** - "Add MCP to Existing Services" guide with 3 approaches
-- **Troubleshooting Guide** - Common MCP issues and solutions
-- **Error Handling Guide** - Patterns for agent-friendly error responses
-- **Documentation Guides** - Six guides: AI-native services, MCP security, tool descriptions, agent patterns, error handling, troubleshooting
-- **WithMCP Option** - One-line MCP setup (`gateway/mcp/option.go`)
-- **Agent Playground Redesign** - Chat-focused UI with collapsible tool calls
-- **Standalone Gateway Binary** - `micro-mcp-gateway` with Docker support
-- **WebSocket Transport** - Bidirectional JSON-RPC 2.0 streaming (`gateway/mcp/websocket.go`)
-- **OpenTelemetry Integration** - Full span instrumentation with W3C trace context (`gateway/mcp/otel.go`)
-- **LlamaIndex SDK** - Python package with RAG examples (`contrib/go-micro-llamaindex/`)

-## Coordination with Codex
-
-Go Micro is maintained by two AI tools — **Claude Code** (you) and **Codex** (its playbook is [CODEX.md](CODEX.md)) — plus the human maintainer, who routes work and owns every merge. To work side by side without collisions:
-
-- **Lanes / branches.** You work on `claude/*` branches; Codex on `codex/*`. Never push to Codex's branch, and never have both agents committing the same branch at once.
-- **Base PRs on `master`; don't stack on Codex's in-flight branch.** If that base squash-merges, your commit gets orphaned (this happened — the #3007 fixes had to be re-landed). If the code you need isn't merged yet, wait for it, then branch off `master`. To improve an *open* Codex PR, fix it in place (once Codex is done with the branch, or via an `@codex` comment on the PR) rather than a separate stacked PR.
-- **One concern per PR.** Single-purpose PRs; don't bundle (e.g.) a feature with a docs change.
-- **Cross-review.** Review Codex's PRs before merge — mechanical fixes you can land yourself (based on `master`), but design/scope/positioning calls go to the human; don't silently rewrite Codex's intent. Codex reviews yours via `@codex review`.
-- **Dispatching Codex.** Start a task by commenting `@codex <instruction>` on an issue/PR (that issue/PR is its context). `@codex review` is reserved for review; any other instruction starts a *task*. It's consequential (spends a Codex task slot, pushes commits) and **serial** (one task at a time) — so dispatch one task at a time, only on the human's go-ahead, and never write a literal `@codex` in a comment unless you intend to trigger it (write "Codex" in prose otherwise).
-- **CI is the gate.** `go build`, `go test`, `golangci-lint` (blocking), and `make harness` must pass before merge. `internal/harness/` and `examples/` are excluded from errcheck; everything else gets the full set.
-- **Backlog = GitHub issues**, each a scoped, self-contained brief with acceptance criteria.

-## Contributing
-
-See [CONTRIBUTING.md](CONTRIBUTING.md) for full guidelines. Key points:
-- Open an issue before large changes
-- Include tests for new features
-- Run `make test` and `make lint` before submitting
-- Follow commit message format: `type: description` (e.g., `feat: add WebSocket transport`)

-# Codex Maintainer Playbook
-
-Go Micro has six months of Codex access through OpenAI's Codex for Open Source
-program. Use it to increase maintainer throughput without changing the project's
-bar for review, tests, or design taste.
-
-## Operating principles
-
-1. **Humans set direction; Codex accelerates execution.** Maintainers choose the
-   issue, constraints, and acceptance criteria. Codex drafts, investigates, and
-   verifies.
-2. **Small, reviewable changes win.** Prefer focused PRs that can be understood
-   in one sitting over large speculative rewrites.
-3. **Keep the contract green.** Every Codex-assisted change should preserve the
-   CLI-first getting-started flow, the harnesses, `make test`, and `make lint`.
-4. **Document while coding.** If behavior changes, ask Codex to update examples,
-   guides, and release notes in the same branch.
-5. **No blind merges.** Codex output is treated like any contributor output:
-   reviewed by a maintainer, backed by tests, and checked for public API impact.
-
-## Coordination with Claude Code
-
-Go Micro is maintained by two AI tools — **Codex** (you) and **Claude Code** (its guide is [CLAUDE.md](CLAUDE.md)) — plus the human maintainer, who routes work and owns every merge.
-
-- **Lanes / branches.** You work on `codex/*` branches; Claude Code on `claude/*`. Never push to a branch the other owns, and never have both agents on one branch at once.
-- **Base PRs on `master`.** Don't stack a PR on another agent's in-flight branch — if that base squash-merges, your changes can be orphaned. If the code you need isn't merged yet, wait, then branch off `master`. To improve a PR that hasn't merged, push to that PR's branch rather than opening a separate stacked PR — keep the change one mergeable unit.
-- **One concern per PR.** Keep each PR single-purpose so a reviewer can read it in one sitting; don't bundle unrelated changes (e.g. a feature plus a docs rebrand).
-- **Cross-review before merge.** Claude Code reviews your PRs; you review its with `@codex review`. A fresh pass from the other model catches what the author misses.
-- **Dispatch.** Maintainers (or Claude Code) start your tasks with `@codex <instruction>` on the relevant issue/PR — that's your context. `@codex review` is review; any other instruction is a *task*. You run one task at a time: take the current one to a clean, green PR before the next is dispatched.
-- **CI is the gate.** `go build`, `go test`, `golangci-lint` (blocking), and `make harness` must pass; never merge red. `internal/harness/` and `examples/` are excluded from errcheck; everything else gets the full set.
-- **Backlog = GitHub issues**, each a scoped brief with acceptance criteria.
-
-## Best uses
-
-### 1. PR review and triage
-
-- Summarize a PR: changed surface area, public API impact, tests added or missing.
-- Ask for targeted review passes: concurrency, cancellation, security, backwards
-  compatibility, docs drift, and examples.
-- Convert review findings into small patch suggestions or issue comments.
-
-### 2. Issue reproduction
-
-- Turn bug reports into failing tests or runnable reproduction scripts.
-- Minimize flakes by isolating registry, broker, store, transport, and AI-provider
-  dependencies behind deterministic fakes where possible.
-- Attach the exact command that reproduces the failure to the issue.
-
-### 3. Release support
-
-- Draft changelog entries from merged commits, grouped by feature, fix, docs, and
-  compatibility notes.
-- Check that `README.md`, `ROADMAP.md`, website docs, examples, and `CHANGELOG.md`
-  agree before tagging.
-- Run dry-run release commands and summarize blockers.
-
-### 4. Docs and examples
-
-- Keep the 0→1 path current: scaffold, run, call, chat, inspect.
-- Keep the 0→hero example current: a realistic multi-agent system that exercises
-  agents, services, flows, MCP, A2A, and observability.
-- Add runnable examples for new primitives before adding broad prose.
-
-### 5. Hardening backlog
-
-Use Codex to break roadmap items into small PRs, especially:
-
-- cross-provider conformance scenarios for all supported AI providers;
-- timeout, cancellation, retry, and rate-limit behavior;
-- durable agent loops on top of the existing checkpoint model;
-- streaming across `ai.Stream` and A2A;
-- agent run metadata mapped to OpenTelemetry spans.
-
-## Suggested weekly loop
-
-1. Pick one maintenance lane: reviews, bugs, release prep, docs, or hardening.
-2. Ask Codex for a branch-sized plan with acceptance criteria and test commands.
-3. Have Codex implement the smallest valuable slice.
-4. Run the relevant checks locally and in CI.
-5. Review the diff as maintainer-owned code, then merge or send it back.
-6. Record any recurring prompt, check, or failure mode in this playbook.
-
-
-## First two weeks
-
-Do not start with a giant feature. Start by making Codex pay rent on maintenance
-work that is already on the roadmap and easy to review.
-
-### Day 1: set up the review loop
-
-1. Pick three recent PRs or commits: one feature, one bug fix, and one docs-only
-   change.
-2. Ask Codex to review each using the PR review template below.
-3. Compare Codex findings with maintainer judgment. Keep the checks that found
-   real issues; delete the noisy ones.
-4. Turn the final review prompt into a saved project note or issue comment
-   template.
-
-Success means Codex can produce a useful first-pass review in under ten minutes
-without blocking a maintainer on false positives.
-
-### Days 2-3: make bugs reproducible
-
-1. Pick one open bug or flaky area.
-2. Ask Codex for a failing test only. Do not allow a fix in the first pass.
-3. Review the test for whether it captures the real contract.
-4. In a second branch, ask Codex to fix the failure with the smallest patch.
-
-Success means every accepted bug fix starts with a regression test or deterministic
-harness case.
-
-### Days 4-5: audit the getting-started contract
-
-Run through the 0→1 path from a clean checkout and ask Codex to patch only the
-first broken or confusing step. The target is not new prose; it is a runnable
-path that works exactly as documented.
-
-Candidate checks:
-
-```sh
-make test
-make harness
-make lint
-go run ./examples/hello-world
-go run ./internal/harness/universe
-```
-
-### Week 2: choose one roadmap slice
-
-Pick one hardening item and break it into PRs that each land independently. The
-best first slice is usually test infrastructure, not product code.
-
-Recommended order:
-
-1. **Provider conformance skeleton**: define one deterministic agent scenario and
-   gate real-provider runs on credentials.
-2. **Cancellation audit**: trace `context.Context` propagation through one package
-   at a time.
-3. **Docs drift audit**: compare `README.md`, `ROADMAP.md`, website docs, and
-   examples for one shipped feature.
-4. **Release checklist dry run**: have Codex build a release-blocker list from the
-   diff since the previous tag.
-
-## Standing task queue
-
-Keep Codex busy on tasks with clear acceptance criteria:
-
-| Priority | Task | Acceptance criteria |
-| --- | --- | --- |
-| P0 | PR first-pass review | Summary, risks, required changes, and exact verification commands. |
-| P0 | Bug reproduction | A failing test or harness case committed before the fix. |
-| P0 | 0→1 docs check | Fresh-checkout commands work as written or a patch fixes the first break. |
-| P1 | Cross-provider conformance | One scenario runs against fakes by default and real providers when keys exist. |
-| P1 | Cancellation hardening | Tests prove timeout/cancel behavior for the touched package. |
-| P1 | Release audit | Changelog, docs, examples, and migration notes agree before tagging. |
-| P2 | Example polish | Example is runnable, linked from docs, and covered by a lightweight check. |
-
-## What not to use Codex for yet
-
-- Broad rewrites without a failing test, benchmark, or public design note.
-- Public API changes before a maintainer writes the compatibility story.
-- Large generated docs that nobody has run.
-- Provider-specific behavior that is not checked against the shared `ai.Model`
-  contract.
-
-## Prompt templates
-
-### PR review
-
-```text
-Review this PR for Go Micro. Focus on public API compatibility, cancellation and
-context propagation, concurrency safety, tests, and docs drift. Return: summary,
-risks, required changes, optional improvements, and exact commands to verify.
-```
-
-### Bug reproduction
-
-```text
-Reproduce this issue in the smallest Go test or harness change possible. Do not
-fix it yet. Explain the failing path and provide the exact command that fails.
-```
-
-### Branch implementation
-
-```text
-Implement the smallest branch that satisfies this issue. Keep the API compatible
-unless explicitly required, update docs/examples when behavior changes, and run
-`make test`, `make harness`, and `make lint` or explain any environment blocker.
-```
-
-### Release audit
-
-```text
-Audit this release branch. Compare CHANGELOG, README, ROADMAP, website docs, and
-examples against the diff since the last tag. List inconsistencies, missing
-migration notes, and checks to run before tagging.

-Go Micro is an **agent harness** and service framework for Go.
+Go Micro is a framework for microservice development.
 
-A harness is the runtime around an agent: the tools it can call, the memory it keeps, the guardrails that bound it, the workflows that trigger it, the services it depends on, and the protocols other agents use to reach it. Go Micro gives you that harness as Go code. Build an agent and it gets a model, memory, tools, planning, delegation, guardrails, and service discovery; it is reachable over [MCP](https://modelcontextprotocol.io/) and [A2A](https://a2a-protocol.org). Write services and every endpoint becomes an AI-callable tool. Orchestrate the deterministic parts with durable flows. Agents, services, and flows share one runtime because an agent is a distributed system, and building one is building a service.
+## Overview
 
-## Sponsors
+Go Micro provides the core requirements for distributed systems development including RPC and Event driven communication. 
+The **micro** philosophy is sane defaults with a pluggable architecture. We provide defaults to get you started quickly 
+but everything can be easily swapped out.

-
-## Quick Start
-
-Install the CLI:
-
-```bash
-# Binary (no Go required)
-curl -fsSL https://go-micro.dev/install.sh | sh
-
-# Or with Go
-go install go-micro.dev/v6/cmd/micro@v6
-```
-
-### Fastest start — no API key
-
-Scaffold a service, run it, call it:
-
-```bash
-micro new helloworld
-cd helloworld
-micro run
-```
-
-Then in another terminal:
-
-```bash
-curl -X POST http://localhost:8080/api/helloworld/Helloworld.Call \
-  -H 'Content-Type: application/json' -d '{"name":"World"}'
-```
-
-### Generate from a prompt — with an LLM key
-
-Set a provider key, describe what you want, and the AI designs services, writes handlers, compiles, and starts them:
-
-```bash
-export ANTHROPIC_API_KEY=sk-ant-...   # or OPENAI_API_KEY, GEMINI_API_KEY, ...
-micro run --prompt "a task management system with categories" --provider anthropic
-```
-
-The AI designs the architecture, you review it, then it generates handlers with real business logic, compiles them, and starts them:
-
-```
-Services:
-  ● task — Task management with status tracking
-  ● project — Project organization
-
-Generate? [Y/n]
-
-Micro
-  Services:
-    ● task
-    ● project
-  Agents:
-    ◆ agent
-```
-
-Then talk to your services from the console:
-
-```
-> Create a project called Launch, then add three tasks to it
-
-→ project_Project_Create({"name":"Launch"})
-← {"record":{"id":"p1..."},"success":true}
-→ task_Task_Create({"title":"Design specs","project_id":"p1..."})
-→ task_Task_Create({"title":"Write code","project_id":"p1..."})
-→ task_Task_Create({"title":"Ship it","project_id":"p1..."})
-
-Created project Launch and added three tasks to it.
-```
-
-When you need a capability that doesn't exist, the agent generates a new service mid-conversation:
-
-```
-> I need to track shipping. Create a shipment for order 123 to London.
-
-  ⚡ generating shipping service...
-  ✓ shipping
-  → shipping_Shipping_Create({"order_id":"123","destination":"London"})
-  ← {"record":{"id":"xyz...","status":"pending"}}
-
-  Created shipment for order 123 going to London.
-```
-
-Edit the generated code by hand at any time — re-running preserves your changes. [Read more](https://go-micro.dev/blog/13).
-
-## Why an Agent Harness
-
-The first wave of agent frameworks helped developers put a model in a loop. The next problem is operating that loop: connecting it to real tools, scoping what it can touch, preserving state, routing work to specialists, recovering from failures, observing what happened, and letting other agents call it. That is harness work.
-
-Go Micro's answer is to make the harness the same thing you already deploy:
-
-- **Tools are services** — endpoint metadata becomes tool schema; RPC executes the call.
-- **Agents are services** — they register, discover, load-balance, and expose `Agent.Chat`.
-- **Workflows are durable code paths** — use flows when the path is known; dispatch to agents when it is not.
-- **Safety lives at execution** — `MaxSteps`, `LoopLimit`, `ApproveTool`, and tool wrappers run where actions happen.
-- **Interop is built in** — MCP for tools, A2A for agents, x402 for paid tools.
-
-Use Go Micro when the agent has to operate a system, not just answer a prompt.
-
-## Writing Services
-
-Under the hood, a service is a struct with methods. Doc comments and `@example` tags become tool descriptions for AI agents automatically.
-
-```go
-package main
-
-import (
-    "context"
-
-    "go-micro.dev/v6"
-)
-
-type Request struct {
-    Name string `json:"name"`
-}
-
-type Response struct {
-    Message string `json:"message"`
-}
-
-type Say struct{}
-
-// Hello greets a person by name.
-// @example {"name": "Alice"}
-func (h *Say) Hello(ctx context.Context, req *Request, rsp *Response) error {
-    rsp.Message = "Hello " + req.Name
-    return nil
-}
-
-func main() {
-    service := micro.NewService("greeter")
-    service.Handle(new(Say))
-    service.Run()
-}
-```
-
-Run it and everything is accessible — REST, gRPC, MCP, agent playground:
-
-```bash
-micro run
-# Dashboard:   http://localhost:8080
-# API:         http://localhost:8080/api/{service}/{method}
-# Agent:       http://localhost:8080/agent
-# MCP Tools:   http://localhost:8080/mcp/tools
-```
-
-You can also scaffold a service from a template:
-
-```bash
-micro new helloworld
-micro new contacts --template crud
-```
-
-## Building Agents
-
-An Agent is a service with an LLM inside it. It has a proto-defined `Agent.Chat` RPC endpoint, registers in the registry, and is callable like any service:
-
-```go
-agent := micro.NewAgent("task-mgr",
-    micro.AgentServices("task", "project"),
-    micro.AgentPrompt("You manage tasks and projects. You understand deadlines and priorities."),
-    micro.AgentProvider("anthropic"),
-)
-agent.Run()
-```
-
-The agent discovers its services from the registry, scopes its tools to their endpoints, and maintains conversation memory in the store. It registers itself so `micro chat` and other agents can find it.
-
-```go
-// Programmatic interaction
-resp, _ := agent.Ask(ctx, "What tasks are overdue?")
-fmt.Println(resp.Reply)
-```
-
-Multiple agents coordinate via RPC — each is a service with an `Agent.Chat` endpoint. `micro chat` routes to the right one.
-
-```bash
-micro agent list                    # list registered agents
-micro call task-mgr Agent.Chat '{"message": "What tasks are overdue?"}'
-```
-
-### Plan & Delegate
-
-Every agent gets two built-in harness capabilities, exposed as tools — no extra setup or separate graph runtime:
-
-- **`plan`** — for multi-step work, the agent records an ordered plan in its store-backed memory and stays oriented across turns.
-- **`delegate`** — the agent hands a self-contained subtask to another agent. If a registered agent already owns the relevant services, the hand-off goes over RPC to that agent; otherwise a focused, short-lived sub-agent is created for the subtask with its own isolated context.
-
-This keeps intelligence distributed: an agent doesn't need to know *how* to do everything, only *who* does. See [examples/agent-plan-delegate](examples/agent-plan-delegate/).
-
-```go
-// A sub-agent is just an agent — created with New, talked to with Ask.
-// delegate-first: reuse a registered agent, or spin up a focused one.
-resp, _ := agent.Ask(ctx, "Plan the launch, create the tasks, and have comms notify the owner.")
-```
-
-### Batteries included, pluggable
-
-Just as a service composes pluggable abstractions (registry, broker, store), an agent composes a **model**, **memory**, and **tools** — sane defaults out of the box, each swappable.
-
-```go
-agent := micro.NewAgent("assistant",
-    micro.AgentProvider("anthropic"),                 // model — swap the provider
-    micro.AgentMemory(micro.NewInMemory(50)),         // memory — default is store-backed & durable
-    micro.AgentTool("weather", "Get the weather for a city",
-        map[string]any{"city": map[string]any{"type": "string"}},
-        func(ctx context.Context, in map[string]any) (string, error) {
-            return getWeather(in["city"].(string))    // tools beyond your services — any function
-        }),
-    micro.AgentMaxSteps(8),                            // guardrails
-)
-```
-
-**Memory** is durable and store-backed by default (Postgres, NATS KV, or file), so an agent picks up where it left off after a restart — or supply your own with `AgentMemory`. **Tools** are your services automatically, plus any function you register with `AgentTool`.
-
-### Paid tools (x402)
-
-Every endpoint is an AI-callable tool — and it can be a *paid* tool. Go Micro supports [x402](https://x402.org), the HTTP 402 payment standard for agents, so a tool can require a stablecoin payment and an agent can settle it autonomously. It's opt-in and carries no crypto in the framework: verification is delegated to a pluggable facilitator (Coinbase, Alchemy, self-hosted), so Base and Solana are just different facilitators.
-
-```bash
-# Charge for tool calls at the MCP gateway (off unless you set a pay-to address)
-micro mcp serve --x402-pay-to 0xYourAddress --x402-network solana --x402-amount 10000
-# Per-tool amounts via a config file
-micro mcp serve --x402-config x402.json
-```
-
-See the [Payments (x402) guide](internal/website/docs/guides/x402-payments.md).
-
-### Reachable by other agents (A2A)
-
-Within a Go Micro system, agents reach each other over RPC. To make them reachable by agents on *other* frameworks, Go Micro speaks the [Agent2Agent (A2A) protocol](https://a2a-protocol.org). The A2A gateway discovers your agents from the registry, generates an Agent Card for each from its metadata — the same way the MCP gateway derives tools from service endpoints — and translates incoming A2A tasks to the agent's `Agent.Chat` RPC. No per-agent code: register an agent and it's reachable over A2A.
-
-```bash
-micro a2a serve --address :4000    # gateway: expose every registered agent over A2A
-micro a2a list                     # agents and their Agent Card URLs
-```
-
-Or skip the gateway entirely — an agent can serve its own A2A endpoint directly, handling tasks in-process:
-
-```go
-micro.NewAgent("task-mgr", micro.AgentServices("task"), micro.AgentA2A(":4000"))
-```
-
-It works both ways. To call an agent on another framework, an `a2a.Client` is wired into the two places that hand off work: `flow.A2A(url)` as a workflow step (the cross-framework `Dispatch`), and `delegate` to an `http(s)` URL from inside an agent.
-
-MCP exposes your services as tools; A2A exposes your agents as agents. See the [A2A guide](internal/website/docs/guides/a2a-protocol.md).

 ## Features
 
-### AI
+Go Micro abstracts away the details of distributed systems. Here are the main features.
 
-| Feature | Details |
-|---------|---------|
-| Agents | `micro.NewAgent()` — intelligent layer that manages services |
-| Plan & delegate | Built-in agent tools — plan multi-step work, delegate subtasks to other agents |
-| Pluggable memory | Durable store-backed conversation memory by default; swap with `AgentMemory` |
-| Custom tools | `AgentTool` — give an agent any function as a tool, beyond its services |
-| Guardrails | `MaxSteps` (stop on count), `LoopLimit` (stop repeated no-progress calls), `ApproveTool` (human-in-the-loop) |
-| Tool middleware | `AgentWrapTool` — wrap tool execution for logging, metrics, or retries (like client/server wrappers) |
-| Workflows | `micro.NewFlow()` — event-driven; one step, ordered durable steps, or triggers an agent |
-| Durable execution | Checkpointed flow steps survive a crash and resume where they stopped; store-backed by default, pluggable backend |
-| MCP gateway | Every endpoint is an AI tool automatically |
-| A2A gateway | Every agent is reachable over the Agent2Agent protocol; cards generated from the registry (`micro a2a`) |
-| Payments (x402) | Opt-in per-call payments for tools via the x402 standard; pluggable facilitator (Base, Solana, …) |
-| 7 LLM providers | Anthropic, OpenAI, Gemini, Groq, Mistral, Together, Atlas Cloud |
-| Interactive console | `micro run` includes a chat console for talking to services |
-| Service generation | `micro run --prompt` — describe a system, get running services |
+- **Service Discovery** - Automatic service registration and name resolution. Service discovery is at the core of micro service 
+development. When service A needs to speak to service B it needs the location of that service. The default discovery mechanism is 
+multicast DNS (mdns), a zeroconf system. You can optionally set gossip using the SWIM protocol for p2p networks or consul for a
+resilient cloud-native setup.
 
-### Framework
+- **Load Balancing** - Client side load balancing built on service discovery. Once we have the addresses of any number of instances 
+of a service we now need a way to decide which node to route to. We use random hashed load balancing to provide even distribution 
+across the services and retry a different node if there's a problem. 
 
-| Feature | Details |
-|---------|---------|
-| Service registry | mDNS (default), Consul, etcd |
-| RPC client/server | gRPC transport, load balancing, streaming |
-| Pub/sub events | NATS, RabbitMQ, HTTP broker |
-| Key-value store | File (bbolt), Postgres, NATS KV |
-| Typed model layer | CRUD + queries, SQLite/Postgres backends |
-| Everything swappable | All abstractions are Go interfaces |
+- **Message Encoding** - Dynamic message encoding based on content-type. The client and server will use codecs along with content-type 
+to seamlessly encode and decode Go types for you. Any variety of messages could be encoded and sent from different clients. The client 
+and server handle this by default. This includes protobuf and json by default.
 
-### Developer experience & deployment
+- **Request/Response** - RPC based request/response with support for bidirectional streaming. We provide an abstraction for synchronous 
+communication. A request made to a service will be automatically resolved, load balanced, dialled and streamed. The default 
+transport is http/1.1 or http2 when tls is enabled.
 
-| Feature | Details |
-|---------|---------|
-| Hot reload | `micro run` watches files, rebuilds on change |
-| Templates | `micro new --template crud/pubsub/api` |
-| One-command deploy | `micro deploy user@server` — SSH + systemd, no Docker |
+- **Async Messaging** - PubSub is built in as a first class citizen for asynchronous communication and event driven architectures. 
+Event notifications are a core pattern in micro service development. The default messaging is point-to-point http/1.1 or http2 when tls 
+is enabled.
 
-## CLI
+- **Pluggable Interfaces** - Go Micro makes use of Go interfaces for each distributed system abstraction. Because of this these interfaces 
+are pluggable and allows Go Micro to be runtime agnostic. You can plugin any underlying technology. Find plugins in 
+[github.com/micro/go-plugins](https://github.com/micro/go-plugins).
 
-| Command | Purpose |
-|---------|---------|
-| `micro run --prompt "..."` | Generate services + agent, start with interactive console |
-| `micro run` | Dev mode: hot reload, gateway, interactive console |
-| `micro run -d` | Detached mode (no console) |
-| `micro chat` | Standalone chat (when not using micro run) |
-| `micro agent list` | List registered agents |
-| `micro new myservice` | Scaffold a service |
-| `micro call service endpoint '{}'` | Call a service or agent from the CLI |
-| `micro build` | Compile production binaries |
-| `micro deploy user@server` | Deploy via SSH + systemd |
+## Getting Started
 
-## Multi-Service Projects
+See the [docs](https://micro.mu/docs/go-micro.html) for detailed information on the architecture, installation and use of go-micro.
 
-Run multiple services together:
-
-```go
-users := micro.NewService("users", micro.Address(":9001"))
-orders := micro.NewService("orders", micro.Address(":9002"))
-
-users.Handle(new(Users))
-orders.Handle(new(Orders))
-
-g := micro.NewGroup(users, orders)
-g.Run()
-```
-
-Or use a `micro.mu` config file:
-
-```
-service users
-    path ./users
-
-service orders
-    path ./orders
-    depends users
-```
-
-## Data Model
-
-Typed persistence with CRUD and queries:
-
-```go
-type User struct {
-    ID    string `json:"id" model:"key"`
-    Name  string `json:"name"`
-    Email string `json:"email" model:"index"`
-}
-
-db := service.Model()
-db.Register(&User{})
-db.Create(ctx, &User{ID: "1", Name: "Alice", Email: "alice@example.com"})
-
-var results []*User
-db.List(ctx, &results, model.Where("email", "alice@example.com"))
-```
-
-Backends: memory (default), SQLite, Postgres.
-
-## AI Providers
-
-Swap providers with a single import — same interface everywhere:
-
-| Provider | Default Model |

+
+Go Micro是基于Golang的微服务开发框架。
+
+## 概览
+
+Go Micro提供分布式系统开发的核心库，包含RPC与事件驱动的通信机制。
+
+**micro**的设计哲学是可插拔的架构理念，她提供可快速构建系统的组件，并且可以根据自身的需求剥离默认实现并自行定制。
+
+<img src="https://micro.mu/docs/images/go-micro.svg" />
+
+所有插件可在仓库[github.com/micro/go-plugins](https://github.com/micro/go-plugins)中找到。
+
+可以订阅我们的[Twitter](https://twitter.com/microhq)或者加入[Slack](http://slack.micro.mu/)论坛。
+
+## 特性
+
+Go Micro把分布式系统的各种细节抽象出来。下面是它的主要特性。
+
+- **服务发现（Service Discovery）** - 自动服务注册与名称解析。服务发现是微服务开发中的核心。当服务A要与服务B协作时，它得知道B在哪里。默认的服务发现系统是Consul，而multicast DNS (mdns，组播)机制作为本地解决方案，或者零依赖的P2P网络中的SWIM协议（gossip）。 
+
+- **负载均衡（Load Balancing）** - 在服务发现之上构建了负载均衡机制。当我们得到一个服务的任意多个的实例节点时，我们要一个机制去决定要路由到哪一个节点。我们使用随机处理过的哈希负载均衡机制来保证对服务请求颁发的均匀分布，并且在发生问题时进行重试。
+
+- **消息编码（Message Encoding）** - 支持基于内容类型（content-type）动态编码消息。客户端和服务端会一起使用content-type的格式来对Go进行无缝编/解码。各种各样的消息被编码会发送到不同的客户端，客户端服服务端默认会处理这些消息。content-type默认包含proto-rpc和json-rpc。
+
+- **Request/Response** - RPC通信基于支持双向流的请求/响应方式，我们提供有抽象的同步通信机制。请求发送到服务时，会自动解析、负载均衡、拨号、转成字节流。默认的传输协议是http/1.1，而tls下使用http2协议。
+
+- **异步消息（Async Messaging）** - 发布订阅（PubSub）头等功能内置在异步通信与事件驱动架构中。事件通知在微服务开发中处于核心位置。默认的消息传送使用点到点http/1.1，激活tls时则使用http2。
+
+- **可插拔接口（Pluggable Interfaces）** - Go Micro为每个分布式系统抽象出接口。因此，Go Micro的接口都是可插拔的，允许其在运行时不可知的情况下仍可支持。所以只要实现接口，可以在内部使用任何的技术。更多插件请参考：[github.com/micro/go-plugins](https://github.com/micro/go-plugins)。

-# Go Micro Roadmap
-
-Go Micro is an **agent harness** and service framework for Go. A harness is the
-runtime around an agent — the tools, memory, guardrails, workflows, state,
-discovery, and protocols it needs to operate a system rather than just answer a
-prompt. An agent is a distributed system — it discovers services, calls them,
-holds state, and recovers from failure — so the harness is the runtime services
-already have, and building an agent is building a service. The roadmap has two
-jobs: make **agentic development** excellent, and make the **developer experience**
-around it excellent.
-
-The full, current roadmap lives at **[go-micro.dev/docs/roadmap](https://go-micro.dev/docs/roadmap)**
-([source](internal/website/docs/roadmap.md)). The highlights:
-
-## Where we are (v6)
-
-Services, agents (`plan`/`delegate`, guardrails, memory, tool middleware), durable
-flows, the MCP and A2A gateways (both directions), x402 paid tools, secure by
-default.
-
-## Principles
-
-1. Build into what people run, never a separate product (no hosted platform, no
-   enterprise edition, no VC).
-2. CLI-first — the CLI is the experience; UI must earn its place, never bloat.
-3. The getting-started flow is a contract: *0→1* (scaffold → run → call) and
-   *0→hero* (a working multi-agent system) must always work and are verified on
-   every change.
-4. Interaction matters as much as running — chatting with agents, inspecting runs
-   and history, end to end.
-5. Battle-tested: works across every provider, fails safely, observable.
-
-## Now — hardening
-
-- **Cross-provider conformance** — the same agent scenario across all seven
-  providers, gated on keys, on a schedule.
-- **Failure & resilience** — timeouts, rate limits, cancellation, deadline/context
-  propagation, retry/backoff.
-- **Getting-started contract** — define and CI-verify the 0→1 and 0→hero flows.
-
-## Next — agentic depth
-
-- **Durable agent loop** — resume a long run via `Checkpoint` (flows already do).
-- **Streaming** — `ai.Stream` + A2A `message/stream`, end to end.
-- **Agent observability** — `RunInfo` → OpenTelemetry spans.
-
-## Later
-
-- Memory management (summarization, retrieval/RAG); human-in-the-loop pause/resume;
-  x402 live-facilitator conformance and paid remote tools with spend caps; A2A
-  streaming, push notifications, and multi-turn tasks.
-
-## Developer experience (ongoing)
-
-- A seamless CLI inner loop (scaffold → run → chat → inspect → deploy); UI
-  discipline (trim what isn't great); a maintained real-world example that doubles
-  as the 0→hero reference; docs kept in lockstep with the code.
-
-## How it's sustained
-
-The framework is the product, funded by sponsorship from those who run it — not a
-hosted service, enterprise tier, or venture funding. See
-[the v6 story](https://go-micro.dev/blog/27).
-
-## Contributing & feedback
-
-Pick an item, open an issue to discuss the approach, and submit a PR. Or join the
-[Discord](https://discord.gg/WeMU5AGxD). Include tests, run `make test` and
-`make lint`.
-
-## Version support
-
-- **v6** — active development (current).
-- **v5** — security fixes only.
-- **v4 and earlier** — end of life.
-
-Major versions (v5 → v6) carry breaking changes; minors are backward-compatible.
-See the [v5 → v6 migration guide](https://go-micro.dev/docs/guides/migration/v5-to-v6).

-- Please give us reasonable time to fix before public disclosure
-- We'll publish a security advisory on GitHub when the fix is released
-
-## Security Best Practices
-
-When using go-micro in production:
-
-### TLS/Transport Security
-
-```go
-import "go-micro.dev/v5/transport"
-
-// Enable TLS verification (recommended)
-os.Setenv("MICRO_TLS_SECURE", "true")
-
-// Or use SecureConfig explicitly
-tlsConfig := transport.SecureConfig()
-```
-
-See [TLS Security Update](internal/website/docs/TLS_SECURITY_UPDATE.md) for details.
-
-### Authentication
-
-```go
-import "go-micro.dev/v5/auth"
-
-// Use JWT authentication
-service := micro.NewService(
-    micro.Auth(auth.NewAuth()),
-)
-```
-
-### Input Validation
-
-Always validate and sanitize inputs in your handlers:
-
-```go
-func (h *Handler) Create(ctx context.Context, req *Request, rsp *Response) error {
-    // Validate input
-    if req.Name == "" {
-        return errors.BadRequest("handler.create", "name is required")
-    }
-    
-    // Sanitize and process
-    // ...
-}
-```
-
-### Rate Limiting
-
-Implement rate limiting for public-facing services:
-
-```go
-import "go-micro.dev/v5/client"
-
-// Client-side rate limiting
-client.NewClient(
-    client.RequestTimeout(time.Second * 5),
-    client.Retries(3),
-)
-```
-
-### Secrets Management
-
-Never commit secrets to version control:
-
-```go
-// Good: Use environment variables
-apiKey := os.Getenv("API_KEY")
-
-// Better: Use a secrets manager
-import "github.com/hashicorp/vault/api"
-```
-
-### Dependency Security
-
-Regularly update dependencies:
-
-```bash
-# Check for vulnerabilities
-go list -json -m all | nancy sleuth
-
-# Update dependencies
-go get -u ./...
-go mod tidy
-```
-
-## Known Security Considerations
-
-### Reflection Usage
-
-go-micro uses reflection for automatic handler registration. While this is a deliberate design choice for developer productivity, be aware:
-
-- Type safety is enforced at runtime, not compile time
-- Malformed requests won't crash services (errors are returned)
-- See [Performance Considerations](internal/website/docs/performance.md)
-
-### TLS Certificate Verification
-
-**Default behavior in v5**: TLS certificate verification is **disabled** for backward compatibility.
-
-**Production recommendation**: Enable secure mode:
-
-```bash
-export MICRO_TLS_SECURE=true
-```
-
-This will be the default in v6.
-
-## Security Updates
-
-Security updates are published as:
-- GitHub Security Advisories
-- Release notes with `[SECURITY]` prefix
-- CVE entries for critical issues
-
-Subscribe to releases: https://github.com/micro/go-micro/releases
-
-## Bug Bounty
-
-We currently do not offer a bug bounty program, but we greatly appreciate responsible disclosure and will publicly credit researchers who report valid security issues.
-
-## Questions?
-
-For security questions that are not vulnerabilities, please:
-- Open a discussion: https://github.com/micro/go-micro/discussions
-- Join Discord: https://discord.gg/WeMU5AGxD
-- Email: support@go-micro.dev

+# Discord input for micro-bot
+[Discord](https://discordapp.com) support for micro bot based on [discordgo](github.com/bwmarrin/discordgo).
+
+This was originally written by Aleksandr Tihomirov (@zet4) and can be found at https://github.com/zet4/micro-misc/.
+
+## Options
+### discord_token
+
+You have to supply an application token via `--discord_token`.
+
+Head over to Discord's [developer introduction](https://discordapp.com/developers/docs/intro)
+to learn how to create applications and how the API works.
+
+### discord_prefix
+
+Set a command prefix with `--discord_prefix`. The default prefix is `Micro `.
+You can mention the bot or use the prefix to run a command.
+
+### discord_whitelist
+
+Pass a list of comma-separated user IDs with `--discord_whitelist`. Only allow
+these users to use the bot.

+
+## Options
+### --telegram_token (required)
+
+Sets bot's token for interacting with API.
+
+Head over to Telegram's [API documentation](https://core.telegram.org/bots/api)
+to learn how to create bots and how the API works.
+
+### --telegram_debug
+
+Sets the debug flag to make the bot's output verbose.
+
+### --telegram_whitelist
+
+Sets a list of comma-separated nicknames (without @ symbol in the beginning) for interacting with bot. Only these users can use the bot.

-# AI Package
-
-The `ai` package provides simple, high-level interfaces for AI model providers. It supports text generation (`Model`), image generation (`ImageModel`), and video generation (`VideoModel`).
-
-## Interfaces
-
-### Text Generation (Model)
-
-The Model interface follows the same patterns as other go-micro packages (Registry, Client, Broker):
-
-```go
-type Model interface {
-    Init(...Option) error
-    Options() Options
-    Generate(ctx context.Context, req *Request, opts ...GenerateOption) (*Response, error)
-    Stream(ctx context.Context, req *Request, opts ...GenerateOption) (Stream, error)
-    String() string
-}
-```
-
-## Quick Start
-
-```go
-import (
-    "context"
-    "go-micro.dev/v5/ai"
-    _ "go-micro.dev/v5/ai/anthropic"
-    _ "go-micro.dev/v5/ai/openai"
-)
-
-// Create a model
-m := ai.New("openai",
-    ai.WithAPIKey("your-api-key"),
-    ai.WithModel("gpt-4o"),
-)
-
-// Generate a response
-req := &ai.Request{
-    Prompt:       "What is Go?",
-    SystemPrompt: "You are a helpful programming assistant",
-}
-
-resp, err := m.Generate(context.Background(), req)
-if err != nil {
-    log.Fatal(err)
-}
-
-fmt.Println(resp.Reply)
-```
-
-### Image Generation (ImageModel)
-
-```go
-type ImageModel interface {
-    GenerateImage(ctx context.Context, req *ImageRequest, opts ...GenerateOption) (*ImageResponse, error)
-    String() string
-}
-```
-
-```go
-import (
-    "go-micro.dev/v5/ai"
-    _ "go-micro.dev/v5/ai/atlascloud"
-)
-
-ig := ai.NewImage("atlascloud",
-    ai.WithAPIKey("your-api-key"),
-)
-
-resp, err := ig.GenerateImage(context.Background(), &ai.ImageRequest{
-    Prompt: "A Go gopher in space",
-    Size:   "1024x1024",
-})
-
-fmt.Println(resp.Images[0].URL)
-```
-
-Providers that support image generation: **Atlas Cloud**, **OpenAI**.
-
-### Video Generation (VideoModel)
-
-```go
-type VideoModel interface {
-    GenerateVideo(ctx context.Context, req *VideoRequest, opts ...GenerateOption) (*VideoResponse, error)
-    String() string
-}
-```
-
-```go
-import (
-    "go-micro.dev/v5/ai"
-    _ "go-micro.dev/v5/ai/atlascloud"
-)
-
-vg := ai.NewVideo("atlascloud",
-    ai.WithAPIKey("your-api-key"),
-)
-
-resp, err := vg.GenerateVideo(context.Background(), &ai.VideoRequest{
-    Prompt:   "Microservices nodes animating with data flowing between them",
-    Images:   []string{"https://example.com/diagram.png"}, // optional: image-to-video
-    Duration: 6,
-})
-
-fmt.Println(resp.URL)
-```
-
-Providers that support video generation: **Atlas Cloud**.
-
-## Options
-
-Configure the model using functional options:
-
-```go
-m := ai.New("anthropic",
-    ai.WithAPIKey("your-key"),              // Required
-    ai.WithModel("claude-sonnet-4-20250514"), // Optional, uses provider default
-    ai.WithBaseURL("https://api.anthropic.com"), // Optional, uses provider default
-)
-```
-
-You can also update options after creation:
-
-```go
-m.Init(
-    ai.WithModel("gpt-4o-mini"),
-    ai.WithAPIKey("new-key"),
-)
-```
-
-## Using Tools
-
-The model can automatically execute tool calls when provided with a tool handler:
-
-```go
-// Define a tool handler. It mirrors a go-micro RPC handler: context
-// first, the call in, a result out.
-toolHandler := func(ctx context.Context, call ai.ToolCall) ai.ToolResult {
-    // Execute the tool and return results
-    switch call.Name {
-    case "get_weather":
-        return ai.ToolResult{ID: call.ID, Value: map[string]string{"temp": "72F"}, Content: `{"temp": "72F"}`}
-    default:
-        return ai.ToolResult{ID: call.ID, Content: `{"error": "unknown tool"}`}
-    }
-}
-
-// Create model with tool handler
-m := ai.New("openai",
-    ai.WithAPIKey("your-key"),
-    ai.WithToolHandler(toolHandler),
-)
-
-// Provide tools in the request
-req := &ai.Request{
-    Prompt: "What's the weather?",
-    SystemPrompt: "You are a helpful assistant",
-    Tools: []ai.Tool{
-        {
-            Name:        "get_weather",
-            Description: "Get current weather",
-            Properties: map[string]any{
-                "location": map[string]any{
-                    "type": "string",
-                    "description": "City name",
-                },
-            },
-        },
-    },
-}
-
-// Generate will automatically call tools and return final answer
-resp, err := m.Generate(context.Background(), req)
-fmt.Println(resp.Answer) // Final answer after tool execution
-```
-
-## Response Structure
-
-```go
-type Response struct {
-    Reply     string      // Initial reply from model
-    ToolCalls []ToolCall  // Tools the model wants to call
-    Answer    string      // Final answer (after tool execution if handler provided)
-}
-```
-

-## Supported Providers
-
-### Anthropic Claude
-
-```go
-m := ai.New("anthropic",
-    ai.WithAPIKey("sk-ant-..."),
-    ai.WithModel("claude-sonnet-4-20250514"), // default
-)
-```
-
-Default model: `claude-sonnet-4-20250514`
-Default base URL: `https://api.anthropic.com`
-
-### OpenAI GPT
-
-```go
-m := ai.New("openai",
-    ai.WithAPIKey("sk-..."),
-    ai.WithModel("gpt-4o"), // default
-)
-```
-
-Default model: `gpt-4o`
-Default base URL: `https://api.openai.com`
-
-### Google Gemini
-
-```go
-m := ai.New("gemini",
-    ai.WithAPIKey("your-key"),
-    ai.WithModel("gemini-2.5-flash"), // default
-)
-```
-
-Default model: `gemini-2.5-flash`
-Default base URL: `https://generativelanguage.googleapis.com`
-
-Google Gemini uses its own API format with `system_instruction`, `contents` (not `messages`), and `functionDeclarations` for tool calling. The provider handles the translation automatically.
-
-### Groq
-
-```go
-m := ai.New("groq",
-    ai.WithAPIKey("your-key"),
-    ai.WithModel("llama-3.3-70b-versatile"), // default
-)
-```
-
-Default model: `llama-3.3-70b-versatile`
-Default base URL: `https://api.groq.com/openai`
-
-Groq provides ultra-fast inference for open-weight models via an OpenAI-compatible endpoint.
-
-### Mistral
-
-```go
-m := ai.New("mistral",
-    ai.WithAPIKey("your-key"),
-    ai.WithModel("mistral-large-latest"), // default
-)
-```
-
-Default model: `mistral-large-latest`
-Default base URL: `https://api.mistral.ai`
-
-Mistral AI is a European AI company offering high-performance models via an OpenAI-compatible endpoint.
-
-### Together AI
-
-```go
-m := ai.New("together",
-    ai.WithAPIKey("your-key"),
-    ai.WithModel("meta-llama/Llama-3.3-70B-Instruct-Turbo"), // default
-)
-```
-
-Default model: `meta-llama/Llama-3.3-70B-Instruct-Turbo`
-Default base URL: `https://api.together.xyz`
-
-Together AI provides fast inference for open-weight models via an OpenAI-compatible endpoint.
-
-### Atlas Cloud
-
-```go
-m := ai.New("atlascloud",
-    ai.WithAPIKey("your-key"),
-    ai.WithModel("llama-3.3-70b"), // default
-)
-```
-
-Default model: `llama-3.3-70b`
-Default base URL: `https://api.atlascloud.ai`
-
-Atlas Cloud is an enterprise AI infrastructure platform offering high-performance LLM APIs. It exposes an OpenAI-compatible chat completions endpoint with tool calling support.
-
-## Auto-Detection
-
-Use `AutoDetectProvider()` to detect the provider from a base URL:
-
-```go
-provider := ai.AutoDetectProvider("https://api.anthropic.com")
-// Returns "anthropic"
-
-m := ai.New(provider, ai.WithAPIKey("..."))
-```
-
-## Adding a New Provider
-
-See the full **[AI Provider Integration Guide](../internal/website/docs/guides/ai-provider-guide.md)** for a step-by-step walkthrough, checklist, and design notes.
-
-Quick summary:
-
-1. Create `ai/yourprovider/yourprovider.go` implementing `ai.Model`.
-2. Call `ai.Register("yourprovider", ...)` in `init()`.
-3. Add tests in `ai/yourprovider/yourprovider_test.go`.
-4. Users enable the provider with a blank import:
-
-```go
-import _ "go-micro.dev/v5/ai/yourprovider"
-```
-
-We welcome contributions and sponsorships from AI infrastructure companies — see the guide for details.
-
-## Comparison with Other Packages
-
-The ai package follows the same patterns as other go-micro packages:
-
-**Registry:**
-```go
-r := registry.NewRegistry(registry.Addrs("..."))
-r.Register(service)
-```
-
-**Client:**
-```go
-c := client.NewClient(client.Retries(3))
-c.Call(ctx, req, rsp)
-```
-
-**AI:**
-```go
-m := ai.New("openai", ai.WithAPIKey("..."))
-m.Generate(ctx, req)
-```
-
-All use:
-- `Init()` to update options
-- `Options()` to get current options
-- `String()` to get the implementation name
-- Functional options pattern
-
-## Testing
-
-```bash
-go test ./ai/...
-```
-
-## Examples
-
-See the [server implementation](../cmd/micro/server/server.go) for a complete example of using the ai package with tool execution.
