+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.
 
-**Bias to capability, not busy-work.** The top of this queue is net-new capability
-from the roadmap's *Now/Next* items. Hardening/conformance/DX polish is background
-work (roadmap *Ongoing*) — kept low here and capped, never allowed to crowd out
-capability. If an area has had several increments with no user-visible gain, it is done
-for now; rank real-headroom capability instead.
+**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.

 ## Work queue (ranked)
 
-### Capability — the headline (roadmap: Now / Next)
+1. **Prevent duplicate delegated notifications in plan-delegate harness** ([#4245](https://github.com/micro/go-micro/issues/4245)) — Now-phase safety is the current red edge after the AtlasCloud 400 fallback shipped: the services → agents → workflows loop must not repeat delegated side effects while recovering or continuing a plan. Make the plan-delegate path idempotent and CI-verifiable before adding more depth.
+2. **Make AtlasCloud guarded delegation pass reliably** ([#4244](https://github.com/micro/go-micro/issues/4244)) — keep cross-provider conformance close behind the side-effect fix: AtlasCloud now gets past the Minimax request-shape 400s, but the live agent harness still misses the required guarded delegate within the retry budget.
+3. **Link examples wayfinding from website getting-started path** ([#4241](https://github.com/micro/go-micro/issues/4241)) — keep adoption weighted with hardening after the examples index shipped: the repo README and CLI now point at the first-agent/0→hero map, but go-micro.dev getting-started and quickstart pages should expose the same path with a CI-guarded docs smoke check.
 
-1. **A2A external-client conformance** ([#4815](https://github.com/micro/go-micro/issues/4815)) — make the gateway easier for non-go-micro agents to discover and stream from by serving the well-known agent card path and spec SSE events.
-2. **AP2 mandate foundation for agent payments** ([#4841](https://github.com/micro/go-micro/issues/4841)) — add opt-in checkout/payment mandate signing and verification so A2A-carried payment authority can settle over x402 without changing defaults.
-3. **Kubernetes CRD reconciler foundation** ([#4842](https://github.com/micro/go-micro/issues/4842)) — turn the shipped alpha `Agent`, `Service`, and `Flow` CRDs into a minimally runnable native deployment path with workload reconciliation and status conditions.
-
-### In flight — do not re-queue
-
-_None right now._
-
-### Background — hardening & DX (roadmap: Ongoing; capped)
-
-_Background hardening is intentionally empty right now. Recent work covered first-agent
-wayfinding, plan/delegate recovery, provider fallback repair, streaming, memory
-compaction, retry controls, provider-failure inspection, x402 buyer safety, gRPC-reflection MCP,
-MCP result conformance, and the alpha Kubernetes CRD surface. Further churn in those
-areas should be marked `needs-human` unless it unlocks a clear user-visible capability._

+architecture-review pass._

-AVOID DIMINISHING-RETURNS CHURN — this is the most important judgment you make. Before ranking anything, ask: *would a real user notice this, or is it the loop grooming itself?* Do NOT queue: another regression-guard/breadcrumb/"verify the docs stay linked" test around docs the loop already wrote; the Nth robustness workaround for a weak provider's malformed output (e.g. AtlasCloud text-tool-call repair) once the agent already tolerates that class; another variation of a subsystem that has been hardened several times recently (e.g. plan/delegate notify/side-effect edge cases). If an area has had several increments with no user-visible gain, it is DONE for now — mark further work there `needs-human` and rank something with real headroom instead (new capability in gateway/flow/model/store, interop depth, observability). A full queue is not the goal; a queue of things that matter is.
+(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__`).
 
-OUTPUT — default to NOT committing. Post a concise assessment as a comment on this issue (#__ISSUE__): what shipped, what's in flight, the top real gaps, and — honestly — whether the recent increments have been high-value or busy-work. Then, in almost all cases, just close this issue (`gh issue close __ISSUE__`) with NO PR.
-
-Open a PR for `.github/loop/PRIORITIES.md` ONLY when the change is MATERIAL — meaning it changes what the builder builds next: (a) the top open item changes, (b) an item is added or removed, or (c) a top item's issue closed and must be dropped. Do NOT open a PR to reorder items below the top, reword descriptions, refresh notes, or "keep it current" — a re-rank that doesn't change the next build is not worth a commit, and this churn is the loop's single biggest waste. When a PR IS warranted: `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`.

-- **Another instance of a class the agent already tolerates** — a weak provider (e.g. AtlasCloud) emitting malformed / text-rendered / partial tool calls, or another plan/delegate notify/side-effect edge case. These have been hardened repeatedly with diminishing returns. Do NOT auto-file yet another routine robustness patch. Comment "recurred — repeated class, capped" on the nearest existing issue and, if it seems genuinely worth more investment, label it `needs-human` for a human to decide. The loop should not keep chasing one weak provider's output shape.
-- **Transient flakes** — live-model latency, provider outages, rate limits, network timeouts with no code cause. Ignore.
-- **Anything needing a breaking or architectural change** — label `needs-human` and describe it.
+IGNORE only genuine transient flakes — live-model latency, provider outages, rate limits, network timeouts with no code cause (mostly relevant to the harness). Anything needing a breaking or architectural change: file it as `needs-human` and describe it, rather than auto-queuing it as a routine fix.

-- **A2A external-client conformance** — the A2A gateway now serves the Agent Card at the spec 0.3.0 `/.well-known/agent-card.json` (keeping `/.well-known/agent.json` as a legacy alias), and `message/stream` emits spec-shaped `status-update`/`artifact-update` events ending in a `final:true` status-update instead of repeated full `Task` snapshots — and never sends `result` and `error` together. Standard A2A clients (ADK, LangGraph, a2a-SDK) can now discover and stream from go-micro agents. (`gateway/a2a/`)
-
-### Fixed
-- **Provider failure inspection metadata** — provider failures recorded during agent runs now retain classification metadata for inspection. (`agent/`, `ai/`)
-
-### Security
-- **x402 spend-cap hardening** — the paying `Client` now refuses a 402 whose `maxAmountRequired` is not a positive integer (a swallowed parse error or negative amount previously bypassed the budget cap), and a new `Config.RequireSettlement` fails closed when a paid request is served by a verify-only facilitator that never captures funds. (`wrapper/x402/`)

-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.

-
-## 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@latest
-```
-
-If install or `PATH` checks fail, use the [install troubleshooting guide](internal/website/docs/guides/install-troubleshooting.md) before scaffolding your first service.
-
-### 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"}'
-```
-
-This install → scaffold → run → call path is covered by no-secret CI harnesses. To
-verify just the local installer and first-run CLI boundaries without network
-access or provider keys, use:
-
-```bash
-make install-smoke
-```
-
-To verify the focused CLI inner-loop contract — scaffold → run/chat/inspect → deploy dry-run — use:
-
-```bash
-make inner-loop
-```
-
-To run only the ordered [0→hero services → agents → workflows transcript](internal/website/docs/guides/zero-to-hero.md) that CI guards, use:
-
-```bash
-make zero-to-hero-transcript
-```
-
-To run the broader local contract (including that transcript, chat/inspect CLI boundaries, and deploy dry-run), use:
-
-```bash
-make harness
-```
-
-### First agent on-ramp
-
-After install and the first `micro new`/`micro run` smoke check, take the
-walkable agent path in this order:
-
-1. [Install troubleshooting](internal/website/docs/guides/install-troubleshooting.md) — verify the binary installer or `go install`, `PATH`, `micro --version`, and the no-secret smoke path before agent work.
-
-Run `make docs-wayfinding` to verify the focused no-secret docs/CLI contract that keeps these README and website commands aligned with the installed CLI.
-
-2. `micro agent demo` — print the provider-free first-agent demo command and next docs steps from the installed CLI.
-3. `micro agent quickcheck` (or `micro agent debug`) — when scaffold → run → chat → inspect stalls, print the short recovery map before you dive into the full debugging guide.
-4. `micro examples` — print the maintained provider-free runnable examples in copy/paste order.
-5. `micro zero-to-hero` — print the maintained one-command no-secret lifecycle harness and runnable examples.
-6. [Examples wayfinding index](examples/INDEX.md) — choose the smallest no-secret first-agent, maintained [0→hero support reference](examples/support/), and next interop examples from one map.
-7. [Smallest first-agent example](examples/first-agent/) — run one service-backed agent with a mock model and no provider key.
-8. [No-secret first-agent transcript](internal/website/docs/guides/no-secret-first-agent.md) — run the
-   maintained support agent with a mock model and see services → agents → workflows succeed without a key.
-9. [Your First Agent](internal/website/docs/guides/your-first-agent.md) — build a
-   service-backed agent and talk to it with `micro chat`.
-10. [Debugging your agent](internal/website/docs/guides/debugging-agents.md) — use
-   `micro agent preflight` before `micro run`, `micro agent doctor` after `micro run`,
-   then `micro chat` and `micro inspect agent <name>` to recover run history, memory,
-   and provider checks when the first conversation does something unexpected.
-11. [0→hero Reference](internal/website/docs/guides/zero-to-hero.md) — complete the
-   services → agents → workflows loop with scaffold, run, chat, inspect, flow
-   history, and deploy dry-run commands that match the maintained harness.
-
-### Autonomous improvement loop
-
-Want the same services → agents → workflows lifecycle applied to your
-repository? `micro loop` scaffolds the autonomous improvement loop used by Go
-Micro itself: a North Star, ranked issue queue, role prompts, GitHub Actions
-workflows, and verification for CI-gated PRs.
-
-```bash
-micro loop init --roles all
-micro loop verify
-```
-
-Before turning on the schedule, configure a dispatch token such as
-`CODEX_TRIGGER_TOKEN`, protect the default branch with required CI checks
-(`go build ./...`, `go test ./...`, and `golangci-lint run ./...` for this
-repository), and seed `.github/loop/PRIORITIES.md` with one scoped issue per
-increment. See the [`micro loop` quickstart](internal/website/docs/guides/micro-loop.md)
-for the setup checklist and operating model.
-
-### 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.AgentCompactMemory(40, 12),                 // memory — durable, summarized, recallable
-    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`. Long-running agents can opt into `AgentCompactMemory(maxMessages, keepRecent)`: older turns are collapsed into a deterministic summary, recent turns stay verbatim, and relevant archived turns are recalled on future asks without replaying the whole conversation. **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).

+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. 
 
-Harness 是围绕智能体的运行时：它能调用的工具、它保留的记忆、约束它的护栏、触发它的工作流、它依赖的服务，以及其他智能体与之通信所使用的协议。
+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.
 
-Go Micro 以 Go 代码的形式提供该 harness。构建一个智能体即可获得模型、记忆、工具、规划、委派、护栏与服务发现；可通过 [MCP](https://modelcontextprotocol.io/) 和 [A2A](https://a2a-protocol.org). 被访问。编写服务后，每个端点都会成为 AI 可调用的工具。用持久化 flow 编排确定性部分。智能体、服务与 flow 共享同一运行时，因为智能体本质上是一个分布式系统，构建智能体就是在构建服务。

-## 为何需要 Agent Harness
+## Why an Agent Harness
 
-第一波代理框架帮助开发者让模型进入循环。下一个问题是如何运营这个循环：将其连接到真实工具、限定可触及范围、保留状态、将工作路由给专家、从故障中恢复、观测发生了什么，并让其他代理调用它。这就是 harness 工作。
+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 的答案是：让 harness 与你已部署的东西合二为一：
+Go Micro's answer is to make the harness the same thing you already deploy:
 
-- **工具即服务** — 端点元数据成为工具 schema；RPC 执行调用。
-- **代理即服务** — 它们注册、发现、负载均衡，并暴露 `Agent.Chat`。
-- **工作流即持久化代码路径** — 路径已知时使用 flows；未知时分派给代理。
-- **安全落在执行层** — `MaxSteps`、`LoopLimit`、`ApproveTool` 以及工具包装器在动作发生处运行。
-- **互操作内置** — 工具用 MCP，代理用 A2A，付费工具用 x402。
+- **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.
 
-当代理需要操作系统而不仅是回答提示时，使用 Go Micro。
+Use Go Micro when the agent has to operate a system, not just answer a prompt.

-### 规划与委托（Plan & Delegate）

-每个代理都具备两种内置 harness 能力，以工具形式暴露——无需额外设置或独立的图运行时：
+Every agent gets two built-in harness capabilities, exposed as tools — no extra setup or separate graph runtime:
 
-- **`plan`** — 对于多步骤工作，代理在其 store 支撑的记忆中记录有序计划，并在多轮对话中保持方向。
-- **`delegate`** — 代理将自包含的子任务交给另一个代理。若已注册的代理已拥有相关服务，则通过 RPC 交接给该代理；否则会为该子任务创建一个专注、短命的子代理，并配备独立隔离的上下文。
+- **`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.
 
-这让智能保持分布式：代理不必知道*如何*完成一切，只需知道*谁*来做。参见 [examples/agent-plan-delegate](examples/agent-plan-delegate/)。
+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/).

-**Memory（记忆）** 默认持久且由 store 支撑（Postgres、NATS KV 或 file），因此代理在重启后可从上次停下的地方继续——也可用 `AgentMemory` 提供你自己的实现。长期运行的代理可选用 `AgentCompactMemory(maxMessages, keepRecent)`：较早轮次被折叠为确定性摘要，最近轮次保持原文，相关归档轮次在未来请求时被召回，而无需重放整段对话。**Tools（工具）** 自动就是你的服务，加上你用 `AgentTool` 注册的任何函数。
+**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`. Long-running agents can opt into `AgentCompactMemory(maxMessages, keepRecent)`: older turns are collapsed into a deterministic summary, recent turns stay verbatim, and relevant archived turns are recalled on future asks without replaying the whole conversation. **Tools** are your services automatically, plus any function you register with `AgentTool`.
 
-### 付费工具（x402）
+### Paid tools (x402)
 
-每个端点都是 AI 可调用的工具——而且可以是*付费*工具。Go Micro 支持 [x402](https://x402.org), 面向代理的 HTTP 402 支付标准，因此工具可要求稳定币支付，代理可自主结算。这是可选功能，框架本身不携带加密货币逻辑：验证委托给可插拔的 facilitator（Coinbase、Alchemy、自托管），因此 Base 和 Solana 只是不同的 facilitator。
+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.

-### 可被其他代理访问（A2A）
+### Reachable by other agents (A2A)
 
-在 Go Micro 系统内，代理通过 RPC 相互访问。要让*其他*框架上的代理也能访问它们，Go Micro 使用 [Agent2Agent (A2A) protocol](https://a2a-protocol.org). A2A 网关从 registry 发现你的代理，根据其元数据为每个代理生成 Agent Card——与 MCP 网关从服务端点派生工具的方式相同——并将传入的 A2A 任务翻译为代理的 `Agent.Chat` RPC。无需为每个代理编写代码：注册代理即可通过 A2A 访问。
+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
 ```
 
-或者完全跳过网关——代理可直接提供自己的 A2A 端点，在进程内处理任务：
+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"))
 ```
 
-双向皆可。要调用其他框架上的代理，`a2a.Client` 会接入两处交接工作的地方：作为工作流步骤的 `flow.A2A(url)`（跨框架的 `Dispatch`），以及从代理内部向 `http(s)` URL 发起的 `delegate`。
+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 将你的服务暴露为工具；A2A 将你的代理暴露为代理。参见 [A2A guide](internal/website/docs/guides/a2a-protocol.md)。
+MCP exposes your services as tools; A2A exposes your agents as agents. See the [A2A guide](internal/website/docs/guides/a2a-protocol.md).

-  emerging agent-payments standard (Google's AP2, standardized via FIDO).
-  Additive and opt-in.
+## Next — agentic depth
 
-## Next — reach & deployment
+- **Durable agent loop** — resume a long run via `Checkpoint` (flows already do).
+- **Streaming** — broaden provider-backed `ai.Stream` coverage and keep chat/A2A streaming end to end.
+- **Agent observability** — `RunInfo` → OpenTelemetry spans.
 
-- **gRPC-reflection MCP** — derive MCP tools from *any* gRPC service via server
-  reflection, not just go-micro-native handlers. Point the gateway at an external
-  gRPC service and its methods become agent tools — a large jump in what an agent
-  can operate.
-- **Kubernetes operator + CRDs** — `Agent`, `Service`, and `Flow` as first-class
-  Kubernetes resources; an operator reconciles them into Deployments wired to the
-  registry. The production deployment story for teams already on K8s.
+## Later
 
-## Later — exploratory
+- Memory management (summarization, retrieval/RAG); human-in-the-loop pause/resume;
+  richer A2A live-stream reconnection (`tasks/resubscribe`) and `input-required`
+  handoffs.
 
-- **Runtime-fitness loop** — a persistently-running dogfood app (Mu) plus an
-  operator/canary loop role, so the autonomous loop evolves go-micro against
-  **real runtime signal** (latency, errors, cost) with canary + rollback — not
-  just green CI. The demand signal the loop is missing today.
-- **HTTP/3 transport**; richer A2A live-stream reconnection (`tasks/resubscribe`,
-  `input-required` handoffs); memory management (summarization, retrieval/RAG).
+## Developer experience (ongoing)
 
-## Ongoing — hardening & DX (background, not the headline)
-
-Continuous but **capped** so it never crowds out capability: cross-provider
-conformance, failure/resilience (timeouts, cancellation, retry/backoff), the
-0→1 and 0→hero getting-started contract, streaming/observability coherence, and a
-seamless CLI inner loop (scaffold → run → chat → inspect → deploy). Real, but
-maintenance — the loop should spend the majority of its cycles on the capability above,
-not here.
+- 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.

-# Kubernetes deployment foundation (alpha)
-
-This package is the first opt-in Kubernetes foundation for the Go Micro lifecycle:
-`Service`, `Agent`, and `Flow` resources. It is intentionally experimental and
-additive. Nothing in the Go Micro runtime installs these resources or changes
-production defaults.
-
-## What is included
-
-- Alpha CRD manifests in `config/crd/` for `agents.micro.dev`,
-  `services.micro.dev`, and `flows.micro.dev`.
-- A small dependency-free mapper that turns a desired Go Micro resource into the
-  Kubernetes `Deployment` shape an operator reconciliation loop will own.
-- Unit tests that validate the structural CRD fragments and dry-run the
-  Agent-to-Deployment mapping.
-
-## Local validation
-
-```sh
-go test ./deploy/kubernetes
-```
-
-If you have a Kubernetes cluster and `kubectl` available, you can also perform a
-server-side dry run of the CRDs:
-
-```sh
-kubectl apply --dry-run=server -f deploy/kubernetes/config/crd/
-```
-
-The manifests are `v1alpha1`; expect the API shape to evolve before this becomes
-a production operator.

-# Agent x402 buyer
-
-This example shows an agent paying for a paid HTTP tool with x402 without using
-live funds or a live chain.
-
-It starts a local paid endpoint guarded by `wrapper/x402` seller middleware and a
-mock facilitator. A deterministic mock-model agent calls that endpoint as a tool,
-receives the HTTP 402 challenge, pays with `AgentPayer`, stays inside
-`AgentBudget`, retries the request, and prints the spend recorded for the run.
-
-```bash
-go run ./examples/agent-x402-buyer
-```
-
-Expected output includes:
-
-- the paid tool response,
-- one facilitator verify and settle call, and
-- `run spend: 7 smallest units (budget 10)`.
-
-The payment token and facilitator are intentionally local development fakes. To
-settle real x402 payments, keep the same `AgentPayer` / `AgentBudget` shape but
-replace the payer with a wallet-backed implementation and configure the seller
-middleware with a hosted or self-run x402 facilitator.
