+# North Star
+
+The direction the loop aligns every increment to. Depth lives in
+[`internal/docs/THESIS.md`](../../internal/docs/THESIS.md); this is the short,
+operative version the planner and builder read each run.
+
+## Mission
+
+Make building an **agent** as easy as building a **service**, on one runtime.
+Go Micro is a holistic agent harness and service framework encapsulating the
+lifecycle of **services → agents → workflows** — pluggable, progressive, and
+AI-native by default.
+
+## Right now — developer adoption
+
+The framework's depth is strong; the **on-ramp** is the gap. Weight the developer
+experience — a walkable first-agent tutorial, discoverable examples, docs
+wayfinding, install friction, debugging, the 0→1 and 0→hero path — **at least as
+highly as internal hardening**. A developer succeeding on their first agent
+matters more right now than another conformance/observability/interop increment.
+Do not let the queue fill entirely with internal depth work.
+
+## Guardrails
+
+- One concern per PR; small and reversible.
+- The gate is green CI (`go build`, `go test`, `golangci-lint`, `make harness`),
+  not human review — keep the suite strong; the loop is only as good as its evaluator.
+- **Off-limits without a human** (surface as notes, never auto-merge): breaking
+  public-API changes, brand/positioning/marketing copy, new dependencies,
+  architectural rewrites, product-default changes with broad behavioral impact.
+- Stay on `claude/*` / `codex/*` branches; base PRs on `master`. See
+  [`CODEX.md`](../../CODEX.md) and [`internal/docs/CONTINUOUS_IMPROVEMENT.md`](../../internal/docs/CONTINUOUS_IMPROVEMENT.md).

+# Priorities
+
+The ranked work queue for the autonomous improvement loop. The
+**architecture-review** pass (the *architect*) owns this file: each run it turns
+the [roadmap](../../ROADMAP.md) plus an internal scan (gaps in the
+services → agents → workflows lifecycle, API coherence, drift, tech debt, test and
+DX friction) into a single ordered list — highest-value first — and links each
+item to a tracking issue. The hourly **continuous-improvement** pass works the
+**top item whose issue is still open**. So the architect decides *what*, and the
+increment loop *builds* it.
+
+**Reading / editing.** An item is done when its linked issue closes (the increment
+that builds it adds `Closes #<issue>`). Roadmap phase (Now → Next → Later) is the
+primary ordering; internal findings are interleaved by value, not kept in a
+separate list. The human can reorder this list — or the issues — at any time to
+redirect the loop; direction always wins.
+
+**Off-limits to the loop** (the architect proposes these as notes, never as queue
+items the loop can auto-merge): brand/positioning copy, breaking public-API
+changes, architectural rewrites. Those go to the human.
+
+## Work queue (ranked)
+
+1. **Make universe checkout conformance send exactly one concierge notification** ([#3633](https://github.com/micro/go-micro/issues/3633)) — durable checkout/universe is the strongest 0→hero proof for services → agents → workflows, and resume idempotency must be boring. Keep this first because duplicate buyer notifications are user-visible side effects in the adoption story and the plan/delegate duplicate-side-effect issue is now closed by PR #3664.
+2. **Make the universe A2A reachability check deterministic** ([#3653](https://github.com/micro/go-micro/issues/3653)) — the latest live-provider scan shows the final universe A2A smoke can trigger extra concierge notifications and time out even after checkout durability assertions pass. Rank it with the universe side-effect work because gateway reachability should prove interop without adding more side effects or making CI flaky.
+3. **Expose `fallback_echo` during A2A streaming fallback conformance** ([#3560](https://github.com/micro/go-micro/issues/3560)) — this remains the next scoped Now-phase interop/conformance gap: it protects the A2A streaming promise developers see in the README and site by ensuring the non-native streaming fallback path receives the tool surface, without letting protocol depth outrank the on-ramp or side-effect safety.
+4. **Parse multi-event A2A SSE fallback responses in the harness** ([#3662](https://github.com/micro/go-micro/issues/3662)) — once the fallback tool path succeeds, the harness must accept legitimate multi-event `message/stream` responses instead of concatenating valid SSE events into invalid JSON. This is a small CI-verifiable harness fix that keeps cross-provider streaming conformance focused on real gateway failures rather than parser brittleness.
+5. **Propagate agent run cancellation and deadlines through model and tool calls** ([#3544](https://github.com/micro/go-micro/issues/3544)) — the highest-value remaining Now-phase resilience gap after the live-provider side-effect fixes 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.

+Act as DevRel for go-micro. Do these, in order.
+
+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 `.github/loop/NORTH_STAR.md` (an agent harness and service framework; the services → agents → workflows lifecycle). Look for: places where README / website / docs contradict each other, are stale, or describe behavior that has since changed (cross-check against the code and recently merged PRs); whether the README is crisp and leads with the harness positioning; and one to three genuinely blog-worthy items from recently shipped work.
+
+CHANGELOG UPKEEP (safe factual task — goes in the auto-merged PR). Keep `CHANGELOG.md` living, in Keep-a-Changelog format with newest content at the top under `## [Unreleased]`. Enumerate PRs merged to master since the last update (`gh pr list --state merged --base master --limit 60 --json number,title,mergedAt,labels`) and add a concise, user-facing entry for each genuine change not yet recorded under the right `### Added` / `### Changed` / `### Fixed` / `### Documentation` subheading — SKIP internal loop/CI/priorities-refresh churn. If a new `vX.Y.Z` tag was cut since the last run (`git fetch --tags --force`), rename `## [Unreleased]` to `## [X.Y.Z] - <Month YYYY>` and open a fresh empty `## [Unreleased]` above it. Do not invent entries.
+
+CHANGELOG BLOG POST (blog voice — do NOT auto-merge). If, and only if, enough user-facing work has accumulated since the last changelog post to be worth reading (roughly a week's worth; not a near-empty post every day), draft a short "What's new in Go Micro" post as the next-numbered file in `internal/website/blog/`, mirroring the latest post's frontmatter and prev-nav, and add an entry at the top of `internal/website/blog/index.html`. Base it strictly on the CHANGELOG.
+
+THEN: (A) post a findings report as a comment on this issue (#__ISSUE__) — what's aligned, what drifted, what you fixed, the CHANGELOG entries added, and whether you drafted a blog post (and why/why not). (B) Open ONE auto-merging PR for the SAFE factual work only — coherence/crispness fixes AND the CHANGELOG update (NOT brand/positioning rewrites, NOT the blog post): `git switch -c codex/coherence-__ISSUE__`, `git push -u origin codex/coherence-__ISSUE__`, `gh pr create --base master --label codex --title "<title>" --body "<summary, Closes #__ISSUE__>"`, then `gh pr merge --squash --auto --delete-branch`. (C) If you drafted a changelog blog post, open it as a SEPARATE PR (`codex/coherence-blog-__ISSUE__`, title prefixed `blog:`) and do NOT enable auto-merge — leave it for the human. Same for any brand/positioning copy. Do not use the make_pr tool.

+-->
+Act as the architect — the founder lens — for go-micro, running continuously alongside the builders. Hold the whole picture: how the harness, the framework, and the developer UX fit together, what is in flight and what just merged, what to prioritize next, and what is missing or has drifted.
+
+(1) TRACK STATE — scan recently merged PRs and open `codex` PRs/issues to see what shipped and what is being built right now, so the queue reflects reality (drop done items, don't re-queue in-flight work).
+
+(2) ASSESS against the North Star in `.github/loop/NORTH_STAR.md` — lead with its Mission (*make building an agent as easy as building a service, on one runtime*) and re-derive alignment from the CANON: the blog under `internal/website/blog`, the `README`, and the website (read these, don't rely on the North Star alone), then `ROADMAP.md` (Now → Next → Later). Judge every priority against the mission: does it make the services → agents → workflows lifecycle simpler, more cohesive, and more operable? CURRENT GOAL — developer adoption: weight the on-ramp (walkable first-agent tutorial, discoverable examples, docs wayfinding, install friction, debugging, 0→1 and 0→hero) at least as highly as internal hardening; do not let the queue fill entirely with internal depth work. Look at coherence and seams across the core packages (agent, ai, flow, gateway/mcp, gateway/a2a, model, server, store, registry) and the dev inner loop (scaffold → run → chat → inspect → deploy). Flag drift in either direction: work drifting from the mission, or the North Star/website drifting from the lived story in the blog.
+
+(3) MAINTAIN THE QUEUE in `.github/loop/PRIORITIES.md` — a SINGLE ordered list, highest-value first, each item linking a scoped, CI-verifiable issue (#N); roadmap phase is the primary ordering, internal findings (cohesion gaps, DX friction, missing pieces) interleaved by value. For any prioritized gap with no issue, file one: `gh issue create --label codex --label enhancement --title "<scoped task>" --body "<goal, scope, acceptance criteria>"`.
+
+OUTPUT: post a concise assessment as a comment on this issue (#__ISSUE__) — what shipped, what's in flight, the top risks/gaps, and the reasoning behind the ranking. If the ranking actually changed, open ONE PR for `.github/loop/PRIORITIES.md`: `git switch -c codex/planner-__ISSUE__`, `git push -u origin codex/planner-__ISSUE__`, `gh pr create --base master --label codex --title "<title>" --body "<summary, Closes #__ISSUE__>"`, then `gh pr merge --squash --auto --delete-branch`. If the queue is already accurate, just close this issue (`gh issue close __ISSUE__`).
+
+Do NOT make breaking public-API or architectural changes yourself — surface those in the assessment as notes for the human, never as auto-merged changes. Open the PR yourself from the shell with `gh`; do not use the make_pr tool (it is a no-op stub).

-# Durable backbone for the autonomous improvement loop

-#
-# 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

-# a PR (git push + gh pr create — the make_pr tool is a no-op stub), and enables

-# collide on the occupied branch and silently fail to open one. A unique issue per

Then do BOTH of these: (A) post a concise findings report as a comment on this issue (#$ISSUE_NUM) — what is aligned, what drifted, what you fixed, and the blog ideas; (B) for SAFE factual-alignment and crispness fixes only (NOT brand/marketing/positioning rewrites), open one PR: \`git switch -c codex/devrel-$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\`. Leave brand/positioning copy and blog drafts for the human — describe them in the report, do NOT open auto-merging PRs for them. 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
+- **`micro loop`** — scaffold an autonomous improvement loop into any repository: GitHub Actions workflows dispatched to an @mention-driven coding agent, across up to five roles — `planner` (ranked queue), `builder` (top item as a single-concern PR, auto-merged on green CI), `triage` (CI failures → fix issues), and opt-in `coherence` (docs/CHANGELOG alignment) and `release` (daily patch tag). Each dispatch role's instruction lives in an editable `.github/loop/prompts/<role>.md` file — the workflow is the mechanism, the prompt is the policy — so a repo customizes behavior without forking the CLI. `micro loop init --roles …` writes it all; `micro loop verify` checks the wiring. This is the loop that maintains go-micro itself, generalized. (`cmd/micro/loop/`)
+
+---
+
+## [6.3.12] - July 2026
+
+### Added
+- **Ollama provider** — run agents against open-weight models locally (`/api/chat`, NDJSON streaming) or via Ollama Cloud (OpenAI-compatible `/v1/chat/completions`, SSE), auto-detected from the base URL, with tool calling in both modes. Point any agent at a non-default endpoint with the new `agent.BaseURL` / `micro.AgentBaseURL` option. (`ai/ollama/`, `examples/agent-ollama/`)
+- **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`)

 ### 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)

+## 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.
 
-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.

+## Provider capability matrix
+
+The CLI can print the provider capabilities registered in the current build:
+
+```bash
+micro ai providers
+```
+
+For automation and docs generation, emit the same matrix as stable JSON:
+
+```bash
+micro ai providers --json
+```
+
+It reports support from Go Micro's provider registry, so the matrix reflects the model, image, and video interfaces available to this binary rather than external provider marketing claims.

 The gateway's scope system uses `auth.Account` from the go-micro framework. Scopes on accounts are the same `[]string` field used by the framework's `auth.Rules` and `wrapper/auth` package. The gateway stores scope requirements in the default store under `endpoint-scopes/<service>.<endpoint>` keys and checks them on every HTTP request.
 
 For service-level (RPC) auth within the go-micro mesh, use the `wrapper/auth` package which provides `auth.Rules` with priority-based access control. See the [auth wrapper documentation](../../wrapper/auth/README.md) for details.
+
+## Self-improving loop (`micro loop`)
+
+Turn a repository into a self-improving one: GitHub Actions workflows that
+dispatch a coding agent to plan, build, and triage — gated by CI. This is the
+same loop that maintains go-micro itself, generalized so any repo (and any
+@mention-driven agent) can use it.
+
+```bash
+micro loop init      # scaffold the loop into the current repo
+micro loop verify    # check a repo is wired correctly
+```
+
+`micro loop init` writes the selected roles' workflows, their prompts, and a queue. Choose roles with `--roles` (default `planner,builder,triage`; `--roles all` for everything):
+
+| Role | Workflow | What it does |
+|------|----------|--------------|
+| Planner | `loop-planner.yml` | Keeps a ranked queue in `.github/loop/PRIORITIES.md` |
+| Builder | `loop-builder.yml` | Builds the top open item as a single-concern PR, auto-merged on green CI |
+| Triage | `loop-triage.yml` | Turns CI failures into scoped fix issues, back into the queue |
+| Coherence | `loop-coherence.yml` | Keeps README/docs/CHANGELOG aligned with the North Star *(opt-in)* |
+| Release | `loop-release.yml` | Cuts the next patch tag when the branch has new commits *(opt-in)* |
+
+The workflows are the **mechanism**; each dispatch role's instruction is an editable file in `.github/loop/prompts/` — the **policy**. Edit those prompts (and `.github/loop/NORTH_STAR.md`) to steer the loop without touching the CLI. That split is what lets go-micro itself use `micro loop` while keeping its own richer prompts.
+
+Common flags:
+
+```bash
+micro loop init \
+  --roles all \
+  --agent @codex \
+  --token-secret LOOP_TOKEN \
+  --branch main \
+  --ci-workflow CI
+```
+
+- `--roles`: which roles to scaffold (`planner,builder,triage`, or `all`)
+- `--agent`: how the workflows summon the agent (an `@mention`)
+- `--token-secret`: repo secret holding the driving user PAT
+- `--branch`: base branch for the loop's PRs
+- `--ci-workflow`: `name:` of the CI workflow triage watches
+- `--tag-prefix`: tag prefix the release role matches and bumps (default `v`)
+
+Two things the CLI can't do for you (and `micro loop verify` reminds you of):
+
+1. **Add the token secret.** The agent ignores `@mentions` from the
+   `github-actions` bot, so dispatch posts as a real user via a PAT stored in
+   the `--token-secret` repo secret. The workflows no-op until it's set.
+2. **Set branch protection.** Require the CI checks with **0 approving reviews**
+   so the builder's native auto-merge lands PRs the moment CI is green — that
+   green-CI gate is the loop's only safety mechanism, so keep the suite strong.

+dispatch a coding agent to plan, build, triage, and (optionally) keep docs
+coherent and cut releases — gated by CI.
+
+Roles (choose with --roles, default: planner,builder,triage):
+  planner    keeps a ranked queue in .github/loop/PRIORITIES.md
+  builder    builds the top open item as a single-concern PR (auto-merged on green CI)
+  triage     turns CI failures into scoped fix issues back into the queue
+  coherence  keeps README/docs/CHANGELOG aligned with the North Star
+  release    cuts the next patch tag when the branch has new commits
+
+Each dispatch role's instruction is an editable file in .github/loop/prompts/ —
+edit those to steer behavior. Direction lives in .github/loop/NORTH_STAR.md.

+<!--
+Seed this with a few real items to give the loop a running start, e.g.:

+For each genuine, self-contained defect, file a scoped issue (`gh issue create --title "<scoped fix>" --body "<root cause, where, acceptance criteria>"`) so the planner/builder can pick it up and the next CI run verifies it.
+
+IGNORE transient flakes — network blips, provider outages, timeouts with no code cause. Anything needing a breaking or architectural change: label it `needs-human` and describe it, rather than auto-filing it as a routine fix.
+
+Close this issue (`gh issue close __ISSUE__`) when triage is done.
