Asim Aslam b49f5072b1 loop: have DevRel maintain CHANGELOG.md and draft a changelog blog post (#3584)
The DevRel pass now keeps the changelog living instead of letting it drift:
each daily run reconciles a Keep-a-Changelog `[Unreleased]` section against the
PRs that actually merged (user-facing entries only; internal loop/CI churn
skipped) and rolls it into a dated version heading whenever loop-release cuts a
new v6.MINOR.PATCH tag. When enough user-facing work has accumulated (roughly a
week's worth, not a near-empty post every day) it also drafts a "what's new"
changelog blog post narrating what shipped.

Autonomy boundary preserved: CHANGELOG.md upkeep is a safe factual change and
rides the auto-merged DevRel PR; the changelog blog post is opened as its own
PR but left for the human to review/merge, since blog voice stays with the human.

Also fix the CHANGELOG preamble: it claimed calendar versions (YYYY.MM) while
tags are semver (v6.MINOR.PATCH). Correct it, add an `[Unreleased]` section
seeded from real recent work, and note the historical 2026.0x headings.

Asim Aslam 66ce68a93f community: add Discord to nav/footer/README/landing; fix stale invite code (#3567)
There was no working, prominent Discord link. Update the stale invite code
(WeMU5AGxD → G8Gk5j3uXr) everywhere it appeared (README, docs, blog, landing,
SECURITY, issue templates, contrib), and add the link prominently: the site
nav and footer includes (so it shows on every landing/docs/blog page), a
Discord badge + a Community line in the README, and a "Join Discord" button on
the landing.

Asim Aslam 4bd181fc21 loop: point the architect at adoption + add a daily release action (#3566)
The framework's depth is strong but the on-ramp is the adoption gap, and the
architect queue had filled entirely with internal hardening. Steer the
architect to weight the developer on-ramp/DX (first-agent tutorial,
discoverable examples, docs wayfinding, install friction, debugging) at least
as highly as internal work — a developer succeeding on their first agent
matters more than another conformance/observability increment. Adoption issues
filed: #3561-#3565.

Also add loop-release.yml: a daily patch release that tags v6.MINOR.PATCH+1
when master has new commits (pushed with the PAT so goreleaser fires), so the
installable framework tracks the loop's daily improvements instead of lapsing.
Minor/major bumps stay with the human.

Asim Aslam 666fc4b794 ci+docs: name the loop workflows by role (planner/generator/evaluator) (#3556)
Rename the autonomous-loop workflows so the Actions list maps to the
long-running-agent harness pattern (planner → generator → evaluator):
  architecture-review.yml   -> loop-architect.yml   "Loop: Architect (Planner)"
  continuous-improvement.yml -> loop-builder.yml     "Loop: Builder (Generator)"
  devrel-review.yml          -> loop-devrel.yml      "Loop: DevRel"
  harness-triage.yml         -> loop-triage.yml      "Loop: Triage (Evaluator feedback)"
harness.yml stays the shared Evaluator/CI gate (triage still matches it by the
"Harness (E2E)" name). Document the pipeline + role mapping in
CONTINUOUS_IMPROVEMENT.md, and point to it from CONTRIBUTING so the development
process is discoverable. No behavior change — schedules, gates, and required
checks are unaffected.

Asim Aslam 7af73b06d7 ci: auto-triage harness failures into fix issues (hill-climbing loop) (#3549)
Close the loop's feedback path: when the live provider-conformance harness
fails, harness-triage.yml dispatches Codex to triage the failing run — read
logs, root-cause, dedupe against open issues, and file scoped codex/enhancement
issues that the hourly increment loop then fixes and the next harness run
verifies. Transient flakes are ignored; breaking/architectural fixes are
escalated as needs-human rather than auto-built. No human in the middle short
of a genuine judgment call. Documented in CONTINUOUS_IMPROVEMENT.md.

Asim Aslam 05e53ec38c ci: run the live provider-conformance harness hourly, not daily (#3540)
Match the real-model conformance cadence to the dev/loop velocity so live
regressions and provider drift surface within the hour instead of up to 24h.
The mock harness already runs on every push/PR; this only changes the live
(credentialed) schedule.

Asim Aslam dbdd0e1d6f atlascloud: run provider conformance on a stronger (env-selectable) model (#3538)
* atlascloud: env-selectable chat model; run conformance on a stronger model

The daily provider-conformance harness fails 4/5 harnesses on Atlas Cloud —
its default chat model answers agent/tool-use conformance prompts
conversationally instead of performing the task. Atlas is currently the only
provider with a key configured, so the whole live run is red.

Make the Atlas Cloud provider honor an ATLASCLOUD_MODEL env override (falling
back to the existing default), and set it in the harness workflow to a
stronger tool-use model (Qwen3, overridable via an Actions variable). No
change to the default for normal use.

* atlascloud: use minimaxai/minimax-m3 for conformance model

COHERENCE AUDIT. Audit the PUBLIC surface — \`README.md\`, \`internal/website/\` (landing \`index.html\` + \`docs/\`), and the blog under \`internal/website/blog/\` — for coherence with the North Star in internal/docs/THESIS.md (an agent harness and service framework; the services → agents → workflows lifecycle). Look for: (1) places where README / website / docs contradict each other, are stale, or describe behavior that has since changed (cross-check against the code and recent merged PRs); (2) whether the README is crisp and leads with the harness positioning; (3) one to three genuinely blog-worthy items from recently shipped work.
CHANGELOG UPKEEP (this is a SAFE factual task — it goes in the auto-merged PR). Keep CHANGELOG.md living, in [Keep a Changelog](https://keepachangelog.com/) format with the newest content at the top under \`## [Unreleased]\`. (a) Enumerate PRs merged to master since the last CHANGELOG update — \`gh pr list --repo $REPO --state merged --base master --limit 60 --json number,title,mergedAt,labels\` — and compare against what CHANGELOG.md already lists. (b) For each genuinely user-facing change not yet recorded (new capability, behavior/API change, notable fix — SKIP purely internal loop/CI/priorities-refresh churn), add a concise entry under the right \`### Added\` / \`### Changed\` / \`### Fixed\` / \`### Documentation\` subheading of \`## [Unreleased]\`, phrased for a user (what it does, which package), not a commit subject. (c) If a new \`v6.MINOR.PATCH\` tag has been cut since the last run (\`git fetch --tags --force\`; compare the newest \`v6.*\` tag to the versions already in CHANGELOG.md), RENAME the current \`## [Unreleased]\` heading to \`## [MINOR.PATCH] - <Month YYYY>\` for that tag and open a fresh empty \`## [Unreleased]\` above it. Keep it accurate — do not invent entries; if nothing user-facing merged, leave [Unreleased] as-is.
CHANGELOG BLOG POST (blog voice — open a PR but do NOT auto-merge; leave it for the human). If — and only if — enough user-facing work has accumulated since the last changelog post to be worth reading (a meaningful batch, roughly a week's worth; do NOT post an almost-empty update every day), draft a short 'What's new in Go Micro' post that narrates what shipped in plain language (grouped by theme, linking the docs/examples, closing with install/upgrade). Create it as the next-numbered file in \`internal/website/blog/\` (find the highest N, use N+1), mirroring the frontmatter (layout/title/permalink/description) and the post-nav 'previous post' link of the latest existing post, and add an entry at the TOP of \`internal/website/blog/index.html\`. Base it strictly on the CHANGELOG — no speculation.
THEN do all of these: (A) post a concise findings report as a comment on this issue (#$ISSUE_NUM) — what is aligned, what drifted, what you fixed, the CHANGELOG entries you added, whether you drafted a changelog post (and why / why not), and any other blog ideas. (B) Open ONE auto-merging PR for the SAFE factual work only — coherence/crispness fixes AND the CHANGELOG.md update (NOT brand/marketing/positioning rewrites, NOT the blog post): \`git switch -c codex/devrel-$ISSUE_NUM\`, \`git push -u origin codex/devrel-$ISSUE_NUM\`, \`gh pr create --base master --label codex --title \"<title>\" --body \"<summary, including 'Closes #$ISSUE_NUM'>\"\`, then \`gh pr merge --squash --auto --delete-branch\`. (C) If you drafted a changelog blog post, open it as a SEPARATE PR on its own branch (\`codex/devrel-blog-$ISSUE_NUM\`) with a title prefixed 'blog:' and do NOT enable auto-merge — leave it open for the human to review and merge. Do the same (separate, non-auto-merged PR or just a report note) for any brand/positioning copy. Do not use the make_pr tool (it is a no-op stub). If you touch code, verify go build/test/golangci-lint. Stay out of breaking public-API changes."

## [Unreleased]
### Added
- **Retrieval-backed agent memory** — agents can recall relevant prior turns by similarity, not just the recent window, with a summarizer hook that compacts older history so long conversations stay in budget. (`agent/`)
- **Scheduled flows** — a flow can run an agent (or any step) on a cron-style schedule, with the dispatch traced end to end. (`flow/`)
- **Flow verification/grader loop** — a workflow can grade its own step output against a rubric and retry until it passes, plus run-trace analysis to surface where a flow spends its time. (`flow/`)
- **A2A streaming & continuity** — outbound agent streaming flows through the A2A binding (`message/stream`), with `tasks/resubscribe` and `input-required` handoffs for multi-turn interop. (`gateway/a2a/`)
### Changed
- **Agent tool-call resilience** — opt-in retries around agent tool calls, and a fallback that executes tool calls emitted as text by weaker models so they still make progress. (`agent/`)
- **Hardened agent durability** — terminal failure statuses are classified and surfaced, and durable resume-after-restart is covered by tests. (`agent/`)
### Documentation
- **"Your first agent" walkthrough** and a canonical 0-to-hero reference path, lowering the on-ramp from install to a running agent. (`internal/website/docs/`)
- **Discord** linked prominently across the README, website nav/footer, and docs. (`https://discord.gg/G8Gk5j3uXr`)

Be respectful, inclusive, and collaborative. We're all here to build great software together.
## How Go Micro is built
Go Micro is developed by an **autonomous improvement loop** — a planner, a
generator, and a separate evaluator, running as scheduled GitHub Actions with a
human setting direction. It's the framework's own thesis (an agent operating a
system) pointed at itself: an agent harness, built by agents. The full process —
the planner → generator → evaluator pipeline, the correctness-only merge gate, and
the guardrails — is documented in
[`internal/docs/CONTINUOUS_IMPROVEMENT.md`](internal/docs/CONTINUOUS_IMPROVEMENT.md).
Human contributions follow the same gate: green CI, one concern per PR.

Go Micro is an **agent harness** and service framework for Go.
**Community:** questions, ideas, or just want to build alongside us? [Join the Discord](https://discord.gg/G8Gk5j3uXr).
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 the 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.

## The pipeline (planner → generator → evaluator)
The development process is an operational instance of the long-running-agent
harness pattern ([Anthropic on harness design](https://www.anthropic.com/engineering/harness-design-long-running-apps)) —
a planner, a generator, and a *separate* evaluator — distributed across GitHub
Actions instead of subagents. Each role is a workflow:
| Role | Workflow (action name) | What it does |
|------|------------------------|--------------|
| **Planner** | `loop-architect.yml`*Loop: Architect (Planner)* | Tracks live state, prioritizes the roadmap + an internal scan, and maintains the ranked queue in [`PRIORITIES.md`](PRIORITIES.md). Decides *what*. |
| **Generator** | `loop-builder.yml`*Loop: Builder (Generator)* | Builds the top open queue item as a single-concern PR (via Codex) and self-merges on green CI. Does the work. |
| **Evaluator** | `harness.yml`*Harness (E2E)*, plus the CI gate (`tests.yaml`, `lint.yaml`) | Grades every change: the mock harness + unit/lint on each push/PR, and real-model conformance hourly. A *separate* grader — never the generator judging itself. |
| **Evaluator → feedback** | `loop-triage.yml`*Loop: Triage (Evaluator feedback)* | On harness failure, root-causes, dedupes, and files scoped fix issues back into the planner's queue. The hill-climbing feedback path. |
| **Coherence** | `loop-devrel.yml`*Loop: DevRel* | Keeps README/website/docs/blog aligned with the North Star, keeps `CHANGELOG.md` living (reconciling `[Unreleased]` against merged PRs and rolling it into version headings as tags cut), and drafts the changelog blog post. |
| **Release** | `loop-release.yml`*Loop: Release (daily patch)* | Cuts a daily patch tag when master has new commits, so the *installable* framework tracks the loop's improvements (triggers `release.yml`/goreleaser). Minor/major bumps stay with the human. |
Generation is separated from evaluation on purpose: an agent grading its own work
reliably over-rates it, so **CI and the harness — not the builder — are the gate**.
The human sets direction and owns the calls that need taste (see Guardrails).

## Failure triage (the feedback loop)
The loop also closes on its own failures. `.github/workflows/loop-triage.yml`
fires when the live provider-conformance harness finishes with `conclusion:
failure` (scheduled/manual runs only), and dispatches Codex to **triage** the
failing run: read the logs, root-cause each distinct failure, **dedupe** against
open issues (comment "recurred" rather than filing a duplicate), and file a scoped
`codex`/`enhancement` issue for each genuine, self-contained defect — which the
increment loop then builds and the next harness run verifies. Transient flakes
(live-model latency, provider outages) are ignored; anything needing a breaking or
architectural change is escalated as `needs-human` instead of auto-built. This is
the hill-climbing layer: CI/harness failures become fixes with no human in the
middle, short of a decision that's genuinely the human's.

## Work queue (ranked)
1. **Add a scheduled agent run harness contract** ([#3486](https://github.com/micro/go-micro/issues/3486)) — with conformance, failure/cancellation hardening, checkpoint resume, memory summarization, and A2A continuity now shipped, the highest-value remaining gap is proving unattended agents as first-class operational-harness workloads. This should compose existing services, agents, flows, store-backed memory, verification, conformance, and run inspection so the scaffold → run → chat → inspect lifecycle extends to scheduled/looping work without adding a hosted scheduler, graph DSL, or breaking public APIs.
2. **Export agent `RunInfo` as OpenTelemetry spans** ([#3501](https://github.com/micro/go-micro/issues/3501)) — once agents can run unattended, operators need production-grade visibility that lines up with the existing tracing stack. Map run lifecycle, checkpoints/resume, tool/delegate steps, and terminal failure/cancellation metadata into OpenTelemetry rather than creating a separate observability surface.
3. **Broaden provider-backed `ai.Stream` conformance** ([#3502](https://github.com/micro/go-micro/issues/3502)) — A2A/chat streaming is now a visible UX seam, but the trust story depends on every provider adapter behaving consistently for streaming deltas, cancellation, and errors. Keep this as a conformance extension with mock/no-secret coverage plus provider-gated checks, so interop hardening stays CI-verifiable.
1. **Make the 0→hero path runnable from the docs** ([#3598](https://github.com/micro/go-micro/issues/3598)) — the debugging guide shipped, so the next highest adoption gap is wayfinding across install, first agent, examples, chat/inspect, and deploy dry-run. Keep this first because the current strategic goal is developer adoption: a new user should be able to walk scaffold → run → chat → inspect → deploy without guessing which guide comes next, and the docs should point at the CI-backed harness that proves it.
2. **Finalize the universe notify step after an agent-backed timeout** ([#3589](https://github.com/micro/go-micro/issues/3589)) — recent live-provider CI exposed a real services → agents → workflows seam: an agent-backed notify side effect can complete while the client observes a timeout, leaving pending flow state and late duplicate notifications. Keep this high because it protects the 0→hero/reliability contract, but leave the adoption guide first so the queue does not drift back to only internal hardening.
3. **Prevent duplicate tool side effects in the plan/delegate harness** ([#3559](https://github.com/micro/go-micro/issues/3559)) — correctness still matters where it protects real user trust. Plan/delegate is central to the services → agents lifecycle, and duplicate side effects undermine the “agent as dependable service” story.
4. **Expose `fallback_echo` during A2A streaming fallback conformance** ([#3560](https://github.com/micro/go-micro/issues/3560)) — keep interop conformance trustworthy without letting it dominate the adoption queue. This is scoped, testable, and protects the A2A promise developers see in the README and site.
5. **Propagate agent run cancellation and deadlines through model and tool calls** ([#3544](https://github.com/micro/go-micro/issues/3544)) — after the on-ramp items, the highest-value remaining Now-phase resilience gap is predictable failure semantics across agent runs, model calls, tool calls, plan/delegate, and flow handoffs. Tool retries and live-provider deadline tuning are in place; the lifecycle still needs cancellation/deadline propagation so work fails safely instead of becoming opaque loops.
6. **Emit OpenTelemetry spans for agent run timelines** ([#3525](https://github.com/micro/go-micro/issues/3525)) — recent work made runs inspectable, correlated trace metadata through scheduled dispatch, verified restart resume, added opt-in tool retries, hardened provider conformance, and fixed provider-emitted text tool calls. The next Next-phase step is to turn that RunInfo foundation into standard OTel spans for agent runs, model calls, tool calls, checkpoint/resume, cancellation/deadlines, and failures.
7. **Add an AP2 mandate layer over A2A and x402** ([#3552](https://github.com/micro/go-micro/issues/3552)) — this is a forward interop investment, not a Now-phase blocker: Go Micro already has A2A agents and x402 paid tools, so a small signed-mandate foundation can keep agent payments aligned with the open-protocol story without pulling the queue away from adoption, resilience, or observability. Keep it additive and opt-in while the AP2/FIDO work settles.

The infrastructure for a system of agents is, for the most part, the infrastructure for a system of services, and that is the decade of work already in the framework.

# Learn by Example
A collection of small, focused examples demonstrating common patterns with Go Micro.
Runnable examples are the fastest way to move from reading the guides to changing
one thing. Start with the path that matches where you are in the services →
agents → workflows lifecycle.
- [Hello Service](hello-service.md)
- [RPC Client](rpc-client.md)
- [Pub/Sub with NATS Broker](pubsub-nats.md)
- [Service Discovery with Consul](registry-consul.md)
- [State with Postgres Store](store-postgres.md)
- [NATS Transport](transport-nats.md)
## Start here
| Goal | Runnable example | Why it is useful |
| --- | --- | --- |
| 0→1 service | [`examples/hello-world`](https://github.com/micro/go-micro/tree/master/examples/hello-world) | Smallest RPC service with a client call and health checks. |
| First service-backed agent | [`examples/agent-demo`](https://github.com/micro/go-micro/tree/master/examples/agent-demo) | Multi-service project/task/team app with agent playground integration. |
| 0→hero lifecycle | [`examples/support`](https://github.com/micro/go-micro/tree/master/examples/support) | No-secret support-desk story: typed services, an agent, an event-driven flow, and a guardrail. |
| Planning and delegation | [`examples/agent-plan-delegate`](https://github.com/micro/go-micro/tree/master/examples/agent-plan-delegate) | Two agents collaborate through `plan` and `delegate` over normal Go Micro RPC. |
| Durable workflows | [`examples/flow-durable`](https://github.com/micro/go-micro/tree/master/examples/flow-durable) | Ordered, checkpointed flow steps resume without duplicating completed side effects. |
| AI-callable services | [`examples/mcp`](https://github.com/micro/go-micro/tree/master/examples/mcp) | MCP examples that expose service endpoints as model tools. |

- [0→hero Reference](../guides/zero-to-hero.html) → run
[`examples/support`](https://github.com/micro/go-micro/tree/master/examples/support)
for the human-readable scenario, then `make harness` for the full CI contract.

title: Debugging your agent
---
# Debugging your agent
Use this guide when an agent surprises you: it answered without using a service,
called the wrong endpoint, looped, lost memory, refused a tool, or behaved
differently when a flow handed work to it. The local inner loop is:
```sh
micro run # start services, agents, gateway, dashboard
micro chat # reproduce one turn
micro inspect ... # read the recorded run or workflow history
```
Debug the lifecycle in the same order Go Micro runs it: first prove the service is
registered and callable, then inspect the agent run that chose tools, then inspect
any workflow that handed off to the agent.
## 1. Reproduce one small turn
Start from the application directory and keep the prompt narrow enough that you
can tell which tool should have run:
```sh
micro run
micro chat --prompt "Create a ticket for Pat, then list open tickets."
```
For a live provider, make the provider choice explicit so a later retry uses the
same model boundary:
```sh
MICRO_AI_PROVIDER=anthropic \
ANTHROPIC_API_KEY="$ANTHROPIC_API_KEY" \
micro chat --prompt "Create a ticket for Pat, then list open tickets."
```
If the provider supports streaming, turn it on while you reproduce the issue:
```sh
micro chat --provider anthropic --stream
```
Streaming shows the final answer as it arrives. Tool execution still goes through
the same agent run and is visible through inspection after the turn completes.
## 2. Prove the service side before blaming the model
Agents only call tools that the runtime can discover and describe. Check the
service boundary first:
```sh
micro services
micro call ticket TicketService.List '{}'
```
If the service is missing, restart the service under `micro run` and verify it is
using the same registry as the agent. If the direct `micro call` fails, fix the
handler, request shape, or auth error there before debugging prompts.
When the agent calls the wrong tool or sends the wrong fields, improve the tool
description at the service source:
```go
// Create opens a customer support ticket and returns its stable ticket ID.
// @example {"customer":"Pat","subject":"Cannot log in"}
func (s *TicketService) Create(ctx context.Context, req *CreateRequest, rsp *CreateResponse) error {
```
Endpoint comments, request field names, `description` tags, and `@example` blocks
are the model's map of your service. A vague handler comment often looks like a
reasoning failure from the outside.
## 3. Inspect agent run history
After a chat turn, list recent runs for that agent:
```sh
micro inspect agent support
```
The output shows the run id, status, number of recorded events, the last event,
errors, and a short trace id when tracing is configured. Narrow the list while you
iterate:
```sh
micro inspect agent support --limit 5
micro inspect agent support --status timeout
micro inspect agent support --trace abc123
micro inspect agent support --json
```
Useful statuses include `done`, `refused`, `timeout`, `rate_limited`, `canceled`,
and `error`. Use `--json` when you want exact timestamps, trace/span ids, and error
kinds for a bug report.
Run timelines are stored in the agent's state store under that agent's scoped
state (`agent/<name>/runs/...`). The persisted timeline is recorded even without
an OpenTelemetry exporter, so `micro inspect agent` remains useful in local
no-secret development.
## 4. See tool calls as they happen
When you are embedding an agent in Go and need live tool visibility, use the
streaming API instead of waiting for the final answer:
```go
stream, err := agent.StreamAsk(ctx, ag, "Create a ticket for Pat")
if err != nil {
return err
}
for {
ev, err := stream.Recv()
if err != nil {
break
}
switch ev.Type {
case agent.StreamEventToolStart:
log.Printf("tool start: %s %#v", ev.ToolCall.Name, ev.ToolCall.Input)
case agent.StreamEventToolEnd:
log.Printf("tool end: %s %#v", ev.ToolCall.Name, ev.Result)
case agent.StreamEventToken:
fmt.Print(ev.Token)
}
}
```
For custom audit logging, wrap the tool execution boundary. Wrappers observe every
call and result, including guardrail refusals:
```go
wrapped := micro.AgentWrapTool(func(next ai.ToolHandler) ai.ToolHandler {
return func(ctx context.Context, call ai.ToolCall) ai.ToolResult {
if run, ok := ai.RunInfoFrom(ctx); ok {
log.Printf("run=%s agent=%s tool=%s", run.RunID, run.Agent, call.Name)
}
res := next(ctx, call)
if res.Refused != "" {
log.Printf("tool refused: %s reason=%s", call.Name, res.Refused)
}
return res
}
})
ag := micro.NewAgent("support", wrapped)
```
Use this when you need request/response payloads in your own logs. By default,
Go Micro records safe run metadata; raw prompt input is not persisted unless the
agent is configured with `agent.TraceInputs(true)`.
## 5. Inspect memory and plans
Default agent memory is store-backed and scoped to the agent name. A restarted
agent with the same `micro.WithStore(...)` and name reloads conversation history
from the `history` key in `agent/<name>` state. If you pass `micro.WithMemory(...)`,
you own that backend; if you pass `agent.NewInMemory(...)`, memory disappears on
restart.
The built-in `plan` tool also saves the current plan to the same scoped agent
state, so a later turn can pick up the saved plan. When memory does not persist,
check that all of these are stable across restarts:
- the agent name (`micro.NewAgent("support", ...)`),
- the configured store backend (`micro.WithStore(...)` or the process default),
- whether a custom in-memory `Memory` implementation replaced the default,
- whether compaction/retrieval limits are intentionally hiding older turns from
the active model context.
## 6. Inspect workflow handoffs
If a flow triggered the agent, inspect the flow too. The flow history tells you
which durable stage dispatched to the agent and whether a run is still pending:
```sh
micro inspect flow intake
micro inspect flow intake --pending
micro inspect flow intake --stage notify
micro inspect flow intake --json
```
The older flow-specific command remains available for listing runs:
```sh
micro flow runs intake
```
Use the flow run id and the agent run id together when debugging handoffs: the
flow explains why work started and where it checkpointed; the agent run explains
which model/tool steps happened after the handoff.
## 7. Add traces when metadata is not enough
For local CLI debugging, `micro inspect` is the fastest path. For production or
multi-service debugging, configure an OpenTelemetry tracer provider on the agent:
```go
ag := micro.NewAgent("support",
micro.AgentTraceProvider(tp),
)
```
Trace ids flow into the recorded run summaries, so you can pivot between
`micro inspect agent support --trace <prefix>` and your trace backend. Keep
`agent.TraceInputs(true)` off unless your observability backend is approved to
store prompt content.
## Troubleshooting table
| Symptom | What to inspect | Common fix |
| --- | --- | --- |
| Agent answers without calling a service | `micro services`, direct `micro call`, then `micro inspect agent <name>` | Register the service, include it in `micro.AgentServices(...)`, or improve endpoint comments and examples. |
| Agent loops or burns steps | `micro inspect agent <name> --status error` and wrapper logs | Add or lower `micro.AgentMaxSteps(...)` / `micro.AgentLoopLimit(...)`; move predictable work into a flow. |
| Tool is refused before it runs | Wrapper logs, `ToolResult.Refused`, `micro inspect agent <name> --status refused` | Update `micro.AgentApproveTool(...)` policy or prompt the user for explicit approval before retrying. |
| Memory is missing after restart | Agent name, store backend, `WithMemory`, compaction/retrieval settings | Use the default store-backed memory with a persistent store, or persist your custom memory backend. |
| Flow handoff appears stuck | `micro inspect flow <flow> --pending`, then `micro inspect agent <agent>` | Resume or fail the pending flow run; confirm the dispatched agent completed or timed out. |
| Provider failed or timed out | `micro inspect agent <name> --status timeout` / `--status rate_limited` | Retry with the same provider/model, raise deadlines where appropriate, or enable provider retries for transient errors. |
| Tool call appears as assistant text | Agent run history and provider conformance checks | Keep provider packages current; Go Micro normalizes provider-emitted text tool calls, and conformance tests guard this behavior. |
## What to include in a bug report
When you cannot explain the run locally, include:
```sh
micro inspect agent <agent> --limit 5 --json
micro inspect flow <flow> --limit 5 --json
micro services
micro call <service> <Handler.Method> '{}'
```
Redact secrets and user data. If you enabled `agent.TraceInputs(true)`, inspect the
JSON before sharing it because prompts may be present.

# Your First Agent
This walkthrough builds the smallest useful Go Micro agent path: one service
with typed endpoints, one agent scoped to that service, and one CLI conversation
that proves the agent can use the service as a tool. It is the 0→1 version of
the services → agents → workflows lifecycle: build capability first, add
intelligence on top, then keep a clear path toward flows when the work needs to
run on events or schedules.
## Runnable reference first
If you want to run the lifecycle before copying code, start with the maintained support-desk example from the repository root:
```sh
go run ./examples/support
```
It uses a deterministic mock model by default, so it needs no provider key, and it exercises the same shape this guide teaches: services become tools, an agent uses them, and a flow can trigger the work. Use this guide when you are ready to build the smaller 0→1 version yourself.
## What you'll build
A tiny task assistant:
1. A `task` service exposes `Create` and `List` endpoints.
2. An `assistant` agent is scoped to the `task` service.
3. `micro run` starts both in the local harness.
4. `micro chat` asks the agent to create and list tasks.
The same service endpoints are normal RPC methods, dashboard/API actions, MCP
tools, and agent tools. You do not write a second integration layer for the
agent.
## Prerequisites
- Go 1.24 or newer.
- The `micro` CLI installed.
- An LLM provider key for live agent calls. For example:
```sh
export ANTHROPIC_API_KEY=sk-ant-...
```
Plain service calls work without a model key; the key is only needed when the
agent reasons over tools.
## 1. Create a workspace
```sh
mkdir first-agent
cd first-agent
go mod init example.com/first-agent
go get go-micro.dev/v6@v6
```
Add `main.go`:
```go
package main
import (
"context"
"fmt"
"os"
"sync"
micro "go-micro.dev/v6"
)
type CreateRequest struct {
Title string `json:"title"`
}
type CreateResponse struct {
ID string `json:"id"`
Title string `json:"title"`
}
type ListRequest struct{}
type ListResponse struct {
Tasks []CreateResponse `json:"tasks"`
}
type TaskService struct {
mu sync.Mutex
next int
tasks []CreateResponse
}
// Create adds a task to the list.
// @example {"title":"Write first agent guide"}
func (t *TaskService) Create(ctx context.Context, req *CreateRequest, rsp *CreateResponse) error {
t.mu.Lock()
defer t.mu.Unlock()
t.next++
*rsp = CreateResponse{ID: fmt.Sprintf("task-%d", t.next), Title: req.Title}
t.tasks = append(t.tasks, *rsp)
return nil
}
// List returns all known tasks.
// @example {}
func (t *TaskService) List(ctx context.Context, req *ListRequest, rsp *ListResponse) error {
t.mu.Lock()
defer t.mu.Unlock()
rsp.Tasks = append([]CreateResponse(nil), t.tasks...)
return nil
}
func main() {
service := micro.NewService("task")
service.Handle(new(TaskService))
agent := micro.NewAgent("assistant",
micro.AgentServices("task"),
micro.AgentPrompt("You help manage tasks. Use the task service before answering."),
micro.AgentProvider("anthropic"),
micro.AgentAPIKey(os.Getenv("ANTHROPIC_API_KEY")),
)
go agent.Run()
service.Run()
}
```
> Why the comments matter: endpoint comments and `@example` tags become tool
> descriptions, so the agent has enough context to choose `task.Create` and
> `task.List` correctly.
## 2. Run the service and agent
From the same directory:
```sh
micro run
```
The local harness starts the service, gateway, dashboard, MCP tool surface, and
agent playground. You can also verify the service directly before involving the
agent:
```sh
micro call task TaskService.Create '{"title":"Ship the walkthrough"}'
micro call task TaskService.List '{}'
```
## 3. Chat with the agent
In another terminal, ask the agent to use the service:
```sh
micro chat assistant
```
Try:
```text
Create a task called "Review the first-agent walkthrough", then show me all tasks.
```
A healthy run shows the agent calling the task service and then summarizing the
result. If the model refuses to call tools, tighten the prompt so it explicitly
uses the `task` service before answering.
## 4. Know what just happened
- The service registered typed RPC endpoints.
- Go Micro derived tool descriptions from the endpoint names, comments, request
fields, and examples.
- The agent registered as another service with an `Agent.Chat` endpoint.
- `micro chat` sent your message to the agent.
- The agent selected the scoped `task` tools, called them over the same runtime,
and stored conversation history in memory.
That is the core lifecycle: services provide capability, agents use the
capability, and the same runtime can later put the interaction behind a flow.
## 5. Make it a workflow when the path is event-driven
Once the prompt should run because something happened rather than because a
human typed a message, move the handoff into a flow:
```go
flow := micro.NewFlow("task-triage",
micro.FlowTrigger("tasks.created"),
micro.FlowPrompt("Review this new task and decide the next action: {{.Data}}"),
micro.FlowProvider("anthropic"),
micro.FlowAPIKey(os.Getenv("ANTHROPIC_API_KEY")),
)
```
Use flows for deterministic triggers and long-running orchestration; keep the
agent for judgment, tool use, and handoffs when the path is not known up front.
## Troubleshooting
| Symptom | Check |
| --- | --- |
| The agent says it cannot access tasks. | Confirm the agent was created with `micro.AgentServices("task")` and that `micro agent list` shows `assistant`. |
| Tool calls use the wrong fields. | Add or improve doc comments and `@example` tags on the service methods. |
| Plain service calls work but chat fails. | Check that your provider key is exported in the shell that runs `micro run`. |
| You need a no-secret reference path. | Run `make harness` from the Go Micro repository; it exercises the services → agents → workflows lifecycle with a mock provider. |
## Next steps
- Read the [0→hero reference path](zero-to-hero.html) for the CI-verified
lifecycle contract.
- Run [`examples/support`](https://github.com/micro/go-micro/tree/master/examples/support) for the no-secret 0→hero support-desk lifecycle.

# 0→hero reference path
The 0→hero path is the maintained, no-secret reference for the Go Micro
services → agents → workflows lifecycle. It ties the CLI inner loop and the
runtime harness together so a contributor can prove the framework still works as
one system, not as separate demos.
Use it when you want to answer: "Can I scaffold a service, run it locally, talk
to an agent, inspect durable work, and reach the deployment boundary without
cloud credentials?"
## What the contract covers
| Boundary | Contract | CI check |
| --- | --- | --- |
| Scaffold | `micro new` generates a runnable service with and without MCP support. | `go test ./cmd/micro/cli/new -run TestZeroToOne -count=1` |
| Run | `micro run` remains the local development entry point. | `go test ./cmd/micro -run TestZeroToHeroCLIBoundaries -count=1` |
| Chat | `micro chat` remains the interactive agent entry point. | `go test ./cmd/micro -run TestZeroToHeroCLIBoundaries -count=1` |
| Inspect | `micro inspect agent`, `micro inspect flow`, and `micro flow runs` remain discoverable for run history. | `go test ./cmd/micro -run TestZeroToHeroCLIBoundaries -count=1` |
| Deploy | `micro deploy --dry-run` resolves deploy targets without touching remote infrastructure. | `go test ./cmd/micro/cli/deploy -run TestDeployDryRun -count=1` |
| Runtime | Real services, agents, durable flows, store-backed history, delegation, and A2A run with only the model mocked. | `./internal/harness/zero-to-hero-ci/run.sh` and `make provider-conformance-mock` |
## Run the runnable example
From the repository root, start with the support-desk example when you want to see the full lifecycle in one terminal:
```sh
go run ./examples/support
```
It starts typed services, a support agent, an event-driven intake flow, and an approval gate with a deterministic mock model. Change one service method, agent prompt, or guardrail decision and run it again to learn the system by modifying a working path.
## Run the whole no-secret path
From the repository root:
```sh
make harness
```
That target runs the scaffold contract, the CLI boundary smoke tests, the
0→hero runtime harnesses, the event-driven agent-flow harness, and mock provider
conformance. It is intentionally deterministic: no provider key, cloud account,
SSH access, or remote service is required.
## Run focused checks while iterating
Use the smaller checks when you are working on one seam:
```sh
# Scaffold → run/call contract.
go test ./cmd/micro/cli/new -run TestZeroToOne -count=1
# CLI inner-loop commands: run, chat, inspect, flow runs, deploy --dry-run.
go test ./cmd/micro -run TestZeroToHeroCLIBoundaries -count=1
go test ./cmd/micro/cli/deploy -run TestDeployDryRun -count=1
# Durable services → agents → workflows reference scenarios.
./internal/harness/zero-to-hero-ci/run.sh
# Event-as-prompt agent flow.
go run ./internal/harness/agent-flow
# Cross-provider semantics with the deterministic mock provider.
make provider-conformance-mock
```
## Reference scenarios
- [`examples/support`](https://github.com/micro/go-micro/tree/master/examples/support)
is the runnable support-desk story: customers, tickets, notify, a support
agent, an intake flow, and an approval gate in one no-secret example.
- [`examples/agent-plan-delegate`](https://github.com/micro/go-micro/tree/master/examples/agent-plan-delegate)
is the smallest runnable planning/delegation example for multiple agents.
- [`internal/harness/plan-delegate`](https://github.com/micro/go-micro/tree/master/internal/harness/plan-delegate)
is the compact 0→hero scenario: real task and notify services, a conductor
agent, a comms agent, plan persistence, delegation, and a workflow handoff.
- [`internal/harness/universe`](https://github.com/micro/go-micro/tree/master/internal/harness/universe)
boots a larger mini-world: inventory, payment, order confirmation, a concierge
agent, durable checkpoint/resume, agent run history, flow run history, and A2A
reachability.
- [`internal/harness/agent-flow`](https://github.com/micro/go-micro/tree/master/internal/harness/agent-flow)
shows the event-driven path where a `user.created` event prompts an agent to
call services and complete onboarding.
Together these scenarios keep the North Star executable: services expose typed
capabilities, agents use those capabilities with memory and guardrails, and
workflows compose the work over time.
## Keeping the guide honest
If you change the CLI inner loop, durable flow APIs, agent run history, or the
provider/tool semantics, update this guide and the harness in the same PR. The
point of 0→hero is not a polished sample app that drifts from reality; it is a
CI-verifiable contract that the documented lifecycle still works.
