-# No Dynamic Import in Production Code
-
-## Rule
-
-Do NOT use `await import()` or dynamic `import()` expressions in production source code.
-Always use static top-level `import` statements.
-
-## Exception (must include a comment explaining why)
-
-1. **Bundle loader** — loads user-authored workflow bundles whose paths are only known at runtime
-
-When suppressing, add a comment directly above:
-

-// Dynamic import required: user bundle path resolved at runtime
-const mod = await import(bundlePath);
-```
-
-## Test Files

-# Sync README
+# Sync Readme
 
-When updating README.md files in this monorepo, follow these conventions.
-
-## Scope
-
-- Root `README.md` — project overview and navigation hub
-- Per-package `packages/*/README.md` — each package self-contained
-
-## Root README Structure
-
-The root README should have these sections in order:
-
-1. **Title and one-liner** — stateless workflow engine driven by single-step CLI
-2. **Overview** — 2-3 paragraphs explaining what it does and key concepts
-3. **Architecture** — dependency layer diagram (text-based)
-4. **Packages** — table with ALL packages from packages/ directory, columns: Package, Description, Type (cli/lib/agent/app)
-5. **Quick Start** — install, build, register workflow, start thread, run step
-6. **CLI Reference** — brief command list, detailed usage in cli-workflow README
-7. **Development** — bun install / build / check / test
-
-## Per-Package README Structure
-
-Each package README should have:
-
-1. **Title** — package name
-2. **One-line description** — matching package.json
-3. **Overview** — what it does, where it sits in the architecture, dependencies
-4. **Installation** — bun add (for libs) or "included as binary" (for cli/agents)
-5. **API** (lib packages) — all exports from src/index.ts with type signatures, grouped by category, minimal usage examples
-6. **CLI Usage** (cli/agent packages) — command reference with examples
-7. **Internal Structure** — brief src/ file organization
-8. **Configuration** (if applicable)
-
-## Execution Steps
-
-### Step 1: Gather current state
-For each package read:
-- package.json (name, version, description, dependencies, bin)
-- src/index.ts (public API exports)
-- Existing README.md (preserve hand-written content worth keeping)
-
-### Step 2: Update root README
-- Ensure ALL packages in packages/ directory are listed in the table
-- Update CLI command reference from uwf --help output
-- Keep Quick Start examples valid
-
-### Step 3: Write/update each package README
-- Follow the per-package structure
-- API section MUST match actual src/index.ts exports — never invent
-- For agent packages: document CLI binary name, how it is invoked
-- For lib packages: document exported types and functions
-- Internal structure: list actual files in src/
-
-### Step 4: Verify
-- All relative links work
-- Package names match package.json
-- No references to removed/renamed packages
-- bun run build still passes
-
-## Guidelines
-
-- Only document what src/index.ts actually exports
-- Root README summarizes, package READMEs go into detail
-- Verify CLI examples against actual commands
-- Preserve existing good prose when updating
-- English for all README content

-# Test Spec: uwf setup model connectivity validation (#335)
-
-## Context
-
-File: `packages/cli-workflow/src/commands/setup.ts`
-Test file: `packages/cli-workflow/src/__tests__/setup-validate.test.ts`
-
-After `cmdSetup` writes config, it should send a test chat completion request to verify the configured model is reachable. If validation fails, warn the user (don't abort — config is already saved).
-
-## Implementation Notes
-
-- Add a `validateModel(baseUrl, apiKey, model)` function that sends a minimal chat completion request (`POST /chat/completions` with `messages: [{role:"user",content:"hi"}]`, `max_tokens: 1`)
-- Returns `Result<void, string>` — ok if 2xx response, error with reason string otherwise
-- Use `AbortSignal.timeout(15_000)` for the request
-- Both `cmdSetup` and `cmdSetupInteractive` should call it after saving config
-- `cmdSetup` returns validation result in its return object: `{ ...existing, validation: { ok: true } | { ok: false, error: string } }`
-- `cmdSetupInteractive` prints a warning to console if validation fails, success message if it passes
-- Use the project logger (`createLogger`) — no raw `console.log` except in interactive CLI output (per CLAUDE.md)
-
-## Test Cases (vitest)
-
-### 1. `validateModel` — success path
-- Mock `fetch` to return `{ status: 200, ok: true, json: () => ({}) }`
-- Call `validateModel(baseUrl, apiKey, model)`
-- Assert returns `{ ok: true, value: undefined }`
-- Assert fetch was called with correct URL (`${baseUrl}/chat/completions`), correct headers (`Authorization: Bearer ${apiKey}`), correct body (model, messages, max_tokens: 1)
-
-### 2. `validateModel` — HTTP error (401 unauthorized)
-- Mock `fetch` to return `{ status: 401, ok: false, statusText: "Unauthorized" }`
-- Call `validateModel(baseUrl, apiKey, model)`
-- Assert returns `{ ok: false, error: <string containing "401"> }`
-
-### 3. `validateModel` — HTTP error (404 model not found)
-- Mock `fetch` to return `{ status: 404, ok: false, statusText: "Not Found" }`
-- Assert returns `{ ok: false, error: <string containing "404"> }`
-
-### 4. `validateModel` — network timeout
-- Mock `fetch` to throw `DOMException` with name `AbortError`
-- Assert returns `{ ok: false, error: <string containing "timeout" or "unreachable"> }`
-
-### 5. `validateModel` — network error (DNS failure, connection refused)
-- Mock `fetch` to throw `TypeError("fetch failed")`
-- Assert returns `{ ok: false, error: <string mentioning connectivity> }`
-
-### 6. `cmdSetup` — includes validation result on success
-- Mock global `fetch` for `/chat/completions` to succeed
-- Call `cmdSetup({ provider, baseUrl, apiKey, model, storageRoot })`
-- Assert returned object has `validation: { ok: true, value: undefined }`
-- Assert config files are still written (existing behavior preserved)
-
-### 7. `cmdSetup` — includes validation result on failure (config still saved)
-- Mock global `fetch` for `/chat/completions` to return 401
-- Call `cmdSetup({ ... })`
-- Assert returned object has `validation: { ok: false, error: ... }`
-- Assert `config.yaml` and `.env` are still written (validation failure doesn't prevent saving)
-
-### 8. `cmdSetupInteractive` — prints success message on validation pass
-- Mock `fetch` for both `/models` and `/chat/completions` to succeed
-- Mock stdin to provide valid selections
-- Capture console output
-- Assert output contains a success message like "Model verified" or "✓"
-
-### 9. `cmdSetupInteractive` — prints warning on validation failure
-- Mock `fetch`: `/models` succeeds, `/chat/completions` returns 401
-- Mock stdin for valid selections
-- Capture console output
-- Assert output contains a warning about model not being reachable and suggests trying a different model
-
-### 10. `validateModel` — request body correctness
-- Mock `fetch` to capture the request body
-- Call `validateModel(baseUrl, apiKey, "test-model")`
-- Assert body is `{ model: "test-model", messages: [{role: "user", content: "hi"}], max_tokens: 1 }`
-
-## Export Requirements
-
-- `validateModel` must be exported (for direct unit testing)
-- Signature: `async function validateModel(baseUrl: string, apiKey: string, model: string): Promise<Result<void, string>>`
-- `Result` type: `{ ok: true; value: T } | { ok: false; error: E }` (project convention)
-
-## Files to Create/Modify
-
-- **New**: `packages/cli-workflow/src/__tests__/setup-validate.test.ts` — all test cases above
-- **Modify**: `packages/cli-workflow/src/commands/setup.ts` — add `validateModel`, integrate into `cmdSetup` and `cmdSetupInteractive`

+# UWF Bootstrap Guide
+
+This guide helps any AI agent set up `uwf` (Uncaged Workflow) from scratch — or self-check and upgrade an existing installation.
+
+## Prerequisites
+
+- **bun** — `uwf` is built with bun. Install: `curl -fsSL https://bun.sh/install | bash`
+- **Network access** — to install npm packages
+
+> **Already have uwf?** Jump to [Self-Check & Upgrade](#self-check--upgrade).
+
+---
+
+## Fresh Install
+
+### 1. Install uwf CLI
+
+```bash
+bun install -g @uncaged/cli-workflow
+```
+
+✅ **Check:** `uwf --version` prints a version number (e.g. `0.5.1`).
+
+### 2. Install Agent Adapter
+
+Install the adapter that matches your agent runtime. Pick **one**:
+
+| Agent | Package | Binary |
+|-------|---------|--------|
+| Hermes | `@uncaged/workflow-agent-hermes` | `uwf-hermes` |
+
+```bash
+# Example: Hermes agent
+bun install -g @uncaged/workflow-agent-hermes
+```
+
+✅ **Check:** `uwf-hermes --version` prints a version number.
+
+### 3. Setup
+
+Run the interactive wizard:
+
+```bash
+uwf setup
+```
+
+Or configure non-interactively:
+
+```bash
+uwf setup \
+  --provider <name> \
+  --base-url <url> \
+  --api-key <key> \
+  --model <model-name> \
+  --agent hermes
+```
+
+This creates `~/.uncaged/workflow/config.yaml` with your provider, model, and default agent.
+
+#### Config Structure
+
+```yaml
+providers:
+  my-provider:
+    baseUrl: https://api.example.com/v1
+    apiKey: sk-xxx
+models:
+  default:
+    provider: my-provider
+    name: my-model
+agents:
+  hermes:
+    command: uwf-hermes
+    args: []
+defaultAgent: hermes
+defaultModel: default
+```
+
+✅ **Check:** `cat ~/.uncaged/workflow/config.yaml` shows valid provider, model, and agent config.
+
+### 4. Verify Installation
+
+```bash
+uwf workflow list    # should return empty array or existing workflows
+uwf skill user       # prints usage guide
+uwf skill author     # prints workflow authoring guide
+```
+
+✅ **Check:** All three commands run without errors.
+
+### 5. Add the uwf Skill
+
+```bash
+mkdir -p ~/.hermes/skills/devops/uwf
+uwf skill bootstrap > ~/.hermes/skills/devops/uwf/SKILL.md
+```
+
+✅ **Check:** `cat ~/.hermes/skills/devops/uwf/SKILL.md` shows the skill content with triggers `uwf`, `workflow`, `工作流`.
+
+### 6. Smoke Test
+
+```bash
+# Register an example workflow
+uwf workflow add examples/analyze-topic.yaml
+
+# Start a thread
+uwf thread start analyze-topic -p "Analyze the concept of technical debt"
+
+# Execute it (one moderator → agent → extract cycle)
+uwf thread exec <thread-id>
+```
+
+✅ **Check:** Thread reaches `completed` status. Verify with `uwf thread list`.
+
+---
+
+## Self-Check & Upgrade
+
+Already have uwf installed? Run through this checklist to verify and upgrade.
+
+### Version Check
+
+```bash
+uwf --version
+uwf-hermes --version   # or your agent adapter
+```
+
+Compare with latest published versions:
+
+```bash
+bun pm ls -g | grep -E "cli-workflow|workflow-agent"
+npm info @uncaged/cli-workflow version
+npm info @uncaged/workflow-agent-hermes version
+```
+
+If local version < published version, upgrade:
+
+```bash
+bun install -g @uncaged/cli-workflow@latest
+bun install -g @uncaged/workflow-agent-hermes@latest
+```
+
+✅ **Check:** `uwf --version` matches `npm info @uncaged/cli-workflow version`.
+
+### Config Check
+
+```bash
+cat ~/.uncaged/workflow/config.yaml
+```
+
+Verify:
+- [ ] `providers` has at least one entry with valid `baseUrl` and `apiKey`
+- [ ] `models.default` references an existing provider
+- [ ] `agents` has your adapter configured
+- [ ] `defaultAgent` and `defaultModel` are set
+
+### Skill Check
+
+```bash
+cat ~/.hermes/skills/devops/uwf/SKILL.md
+```
+
+Verify the skill is up to date:
+
+```bash
+uwf skill bootstrap | diff - ~/.hermes/skills/devops/uwf/SKILL.md
+```
+
+If `diff` produces any output, the local skill is outdated. Update:
+
+```bash
+uwf skill bootstrap > ~/.hermes/skills/devops/uwf/SKILL.md
+```
+
+### Functional Check
+
+```bash
+uwf workflow list      # should not error
+uwf skill user         # should print usage guide
+uwf skill author       # should print authoring guide
+```
+
+✅ All green? You're good to go.

+# Contributing to @uncaged/workflow
+
+Thank you for your interest in contributing! This guide covers setup, conventions, and the PR workflow.
+
+## Prerequisites
+
+- [Bun](https://bun.sh/) (latest)
+- [Node.js](https://nodejs.org/) 20+
+- Git
+
+## Setup
+
+```bash
+git clone https://github.com/shazhou-ww/uncaged-workflow.git
+cd uncaged-workflow
+bun install
+bun run build
+bun test
+```
+
+## Development Workflow
+
+```bash
+bun run build     # TypeScript compilation (all packages)
+bun run check     # tsc + biome lint + log tag validation
+bun run format    # Auto-format with Biome
+bun test          # Run all tests
+```
+
+All three (`build`, `check`, `test`) must pass before submitting a PR. A pre-push hook runs `check` + `test` automatically.
+
+## Coding Conventions
+
+See [CLAUDE.md](CLAUDE.md) for the full coding standard. Key points:
+
+- **Functional-first** — `function` + `type`, not `class` + `interface`
+- **No optional properties** — use `T | null` instead of `?:`
+- **Named exports only** — no default exports
+- **No `console.log`** — use the structured logger from `@uncaged/workflow-util`
+- **Static imports only** — no `await import()` in production code
+- **Biome** for lint + format — run `bun run check` before committing
+

+A stateless workflow engine driven by a single-step CLI. Workflows are YAML definitions with roles, status-based routing, and a directed graph. Threads are immutable CAS-linked chains — each `uwf thread step` runs one moderator→agent→extract cycle and exits.
 
 ## Overview
 
-This monorepo implements **uwf**, a workflow engine with no long-running daemon. You register YAML workflow definitions in a content-addressed store (CAS), start a thread with an initial prompt, then invoke `uwf thread step` repeatedly until the moderator routes to `$END`. Each step is a complete process: the moderator evaluates JSONata conditions to pick the next role, an external agent CLI produces frontmatter markdown output, and an extract pipeline validates or structures that output against the role's JSON Schema.
+This monorepo implements **uwf**, a workflow engine with no long-running daemon. You register YAML workflow definitions in a content-addressed store (CAS), start a thread with an initial prompt, then invoke `uwf thread step` repeatedly until the moderator routes to `$END`. Each step is a complete process: the moderator evaluates status-based routing to pick the next role, an external agent CLI produces frontmatter markdown output, and an extract pipeline validates or structures that output against the role's JSON Schema.
 
 Workflow state lives entirely on disk under `~/.uncaged/workflow/`: CAS nodes for definitions and step payloads, `registry.yaml` for workflow name→hash mappings, and `threads.yaml` for active thread head pointers. Completed threads are archived to `history.jsonl`. Because there is no server process, workflows are easy to debug, fork, and inspect with ordinary CLI tools.
 
 Agents are pluggable CLI binaries (`uwf-hermes`, `uwf-builtin`, `uwf-claude-code`, or custom commands). The engine spawns the configured agent with `<thread-id>` and `<role>`, sets `UWF_EDGE_PROMPT` from the graph transition, and captures both the agent's markdown output and a detail CAS node for session replay.
 
+## Install
+
+```bash
+npm install -g @uncaged/cli-workflow
+```
+
+Requires [Bun](https://bun.sh/) runtime (used internally for TypeScript execution).
+
+## Quick Start
+
+```bash
+# 1. Configure provider, model, and default agent
+uwf setup
+
+# 2. Register a workflow from YAML
+uwf workflow add examples/solve-issue.yaml
+
+# 3. Start a thread (creates head pointer; does not execute)
+uwf thread start solve-issue -p "Fix the login redirect bug"
+
+# 4. Execute steps (one at a time, until done)
+uwf thread exec <thread-id>
+```
+
+Use `-c, --count <number>` on `thread exec` to run multiple steps in one invocation. Override the agent with `--agent <cmd>`.

+# Sync README
+
+When updating README.md files in this monorepo, follow these conventions.
+
+## Scope
+
+- Root `README.md` — project overview and navigation hub
+- Per-package `packages/*/README.md` — each package self-contained
+
+## Root README Structure
+
+The root README should have these sections in order:
+
+1. **Title and one-liner** — stateless workflow engine driven by single-step CLI
+2. **Overview** — 2-3 paragraphs explaining what it does and key concepts
+3. **Architecture** — dependency layer diagram (text-based)
+4. **Packages** — table with ALL packages from packages/ directory, columns: Package, Description, Type (cli/lib/agent/app)
+5. **Quick Start** — install, build, register workflow, start thread, run step
+6. **CLI Reference** — brief command list, detailed usage in cli-workflow README
+7. **Development** — bun install / build / check / test
+
+## Per-Package README Structure
+
+Each package README should have:
+
+1. **Title** — package name
+2. **One-line description** — matching package.json
+3. **Overview** — what it does, where it sits in the architecture, dependencies
+4. **Installation** — bun add (for libs) or "included as binary" (for cli/agents)
+5. **API** (lib packages) — all exports from src/index.ts with type signatures, grouped by category, minimal usage examples
+6. **CLI Usage** (cli/agent packages) — command reference with examples
+7. **Internal Structure** — brief src/ file organization
+8. **Configuration** (if applicable)
+
+## Execution Steps
+
+### Step 1: Gather current state
+For each package read:
+- package.json (name, version, description, dependencies, bin)
+- src/index.ts (public API exports)
+- Existing README.md (preserve hand-written content worth keeping)
+
+### Step 2: Update root README
+- Ensure ALL packages in packages/ directory are listed in the table
+- Update CLI command reference from uwf --help output
+- Keep Quick Start examples valid
+
+### Step 3: Write/update each package README
+- Follow the per-package structure
+- API section MUST match actual src/index.ts exports — never invent
+- For agent packages: document CLI binary name, how it is invoked
+- For lib packages: document exported types and functions
+- Internal structure: list actual files in src/
+
+### Step 4: Verify
+- All relative links work
+- Package names match package.json
+- No references to removed/renamed packages
+- bun run build still passes
+
+## Guidelines
+
+- Only document what src/index.ts actually exports
+- Root README summarizes, package READMEs go into detail
+- Verify CLI examples against actual commands
+- Preserve existing good prose when updating
+- English for all README content

+      **Mode B — Continue on existing PR (prompt mentions PR, branch, or review feedback):**
+      YOU MUST output $status=continue (NOT ready) when in this mode.

+# @uncaged/workflow-moderator
+
+Status-based graph evaluator — determines the next role or `$END` with zero LLM cost.
+
+## Overview
+
+The moderator (Layer 1) performs a status-based map lookup on the workflow graph. Given the last role and its output, it looks up `graph[lastRole][lastOutput.status]` to find the next `Target` (role + prompt template). The prompt is rendered via Mustache with `lastOutput` as the template context. For `$START`, the unit status `_` is used.
+
+**Dependencies:** `@uncaged/workflow-protocol`, `mustache`
+
+## Installation
+
+```bash
+bun add @uncaged/workflow-moderator
+```
+
+## API
+
+### Functions
+
+```typescript
+function evaluate(
+  graph: Record<string, Record<string, Target>>,
+  lastRole: string,
+  lastOutput: Record<string, unknown> & { status: string },
+): Result<EvaluateResult, Error>
+```
+
+Returns `{ ok: true, value: { role, prompt } }` where `role` is the next role name or `"$END"`, and `prompt` is the rendered edge instruction for the agent.
+
+### Types
+
+```typescript
+type EvaluateResult = {
+  role: string;
+  prompt: string;
+};
+```
+
+The `Result<T, E>` type is local to this package (`{ ok: true; value: T } | { ok: false; error: E }`), not re-exported from `index.ts`.
+
+## Usage
+
+```typescript
+import { evaluate } from "@uncaged/workflow-moderator";
+import type { Target } from "@uncaged/workflow-protocol";
+
+const result = evaluate(graph, lastRole, lastOutput);
+if (result.ok && result.value.role !== "$END") {
+  console.log(`Next role: ${result.value.role}, prompt: ${result.value.prompt}`);
+}
+```

 Layer 4 entry point for the workflow engine. The `uwf` binary orchestrates one step per invocation: load thread head from `threads.yaml`, run the moderator, spawn the configured agent CLI, run extract, append a CAS step node, and update the head pointer (or archive when `$END`).
 
+### Four-Layer Architecture
+
+```
+workflow → thread → step → turn
+模板定义   执行实例   单步结果   agent内部交互
+```
+
+- **Workflow** (layer 1): YAML template with roles and routing graph
+- **Thread** (layer 2): Single workflow execution instance
+- **Step** (layer 3): One moderator→agent→extract cycle
+- **Turn** (layer 4): Agent-internal interactions (use `step show` or CAS to inspect)
+
 This package has no library `src/index.ts` — it is consumed as a CLI binary only.

+## Migration Guide
+
+### Breaking Changes (v0.x → v1.x)
+
+The CLI was reorganized to clarify the four-layer architecture. **No backward compatibility** — old commands have been removed.
+
+#### Renamed Commands
+
+| Old Command | New Command | Notes |
+|------------|-------------|-------|
+| `workflow put` | `workflow add` | More intuitive verb |
+| `thread step` | `thread exec` | Eliminates ambiguity with "step" noun |
+| `thread list --all` | `thread list --status completed` | Unified status filtering |
+
+#### Removed Commands (Merged)
+
+| Old Command | New Command | Notes |
+|------------|-------------|-------|
+| `thread running` | `thread list --status running` | Merged into unified list |
+
+#### Removed Commands (Split)
+
+| Old Command | New Commands | Notes |
+|------------|-------------|-------|
+| `thread kill` | `thread stop` or `thread cancel` | `stop` keeps thread active, `cancel` archives it |
+
+#### Moved Commands
+
+| Old Command | New Command | Notes |
+|------------|-------------|-------|
+| `thread steps` | `step list` | Moved to step layer |
+| `thread step-details` | `step show` | Moved to step layer |
+| `thread fork` | `step fork` | Moved to step layer (forks are step-based) |
+
+#### Deprecation Errors
+
+Old commands now show helpful error messages:
+
+```bash
+$ uwf thread step 01ARZ3NDEKTSV4RRFFQ69G5FAV
+Error: Command 'thread step' has been removed.
+Use 'thread exec' instead.
+
+For more information, see: uwf help thread exec
