 Workflow bundles (`.esm.js`) follow the same rule: export `const run` and `const descriptor`, not `export default`.
 
+### Folder Module Discipline
+
+Every folder under `src/` is a **module boundary**. Four rules:
+
+| # | Rule | Rationale |
+|---|------|-----------|
+| 1 | **Every folder exports via `index.ts`** | Single entry point for the module |
+| 2 | **Types live in `types.ts`** | Each folder's type definitions go in `<folder>/types.ts`, not scattered across files |
+| 3 | **Single export source** | Only `index.ts` may re-export. No file may re-export from another module's internals. Cross-module imports must go through `index.ts` — never reach past it to import a specific file |
+| 4 | **`index.ts` is pure re-exports** | No type definitions, no function implementations — only `export { ... } from` statements |
+
+```typescript
+// ✅ Good — import through module boundary
+import { createCasStore } from "../cas/index.js";
+import type { CasStore } from "../cas/index.js";
+
+// ❌ Bad — reaching past index.ts
+import { createCasStore } from "../cas/cas.js";
+
+// ❌ Bad — re-exporting from non-index file
+// in engine/engine.ts:
+export { createCasStore } from "../cas/cas.js";
+
+// ❌ Bad — types defined in index.ts
+// in cas/index.ts:
+export type CasStore = { ... };  // should be in cas/types.ts
+```
+
+**Exception**: The package-level `src/index.ts` is the public API surface and re-exports from folder `index.ts` files. Files that remain at `src/` root (e.g. `types.ts`, `workflow-as-agent.ts`) are not inside a folder module and follow normal rules.

+# @uncaged/workflow
+
+A workflow engine that executes single-file ESM bundles. Each workflow is a self-contained `.esm.js` file identified by its XXH64 hash (Crockford Base32).
+
+## Core Concepts
+
+| Concept | Description |
+|---------|-------------|
+| **Workflow** | A single-file ESM module exporting `run` (workflow function) and `descriptor` (metadata). Identified by its XXH64 hash. |
+| **Bundle** | The physical `.esm.js` file stored in `~/.uncaged/workflow/bundles/`. |
+| **Thread** | A single execution of a workflow, identified by a ULID. Persisted as `.data.jsonl` + `.info.jsonl`. |
+| **Role** | A named actor within a workflow. Each role produces output with typed `meta`. Roles live inside template packages (`src/roles/`). |
+| **Registry** | `workflow.yaml` — maps workflow names to current/historical bundle hashes. |
+| **CAS** | Content-Addressed Storage — bundles are immutable and addressed by hash. |
+
+## Monorepo Packages
+
+```

+
+## Quick Start
+
+```bash
+# Install dependencies
+bun install
+
+# Build all packages
+bun run build
+
+# Register a workflow bundle
+uncaged-workflow workflow add solve-issue dist/packages/workflow-template-solve-issue/solve-issue.esm.js
+
+# Run a workflow
+uncaged-workflow run solve-issue --prompt "Fix bug #42"
+```
+
+## CLI Usage
+
+```bash
+uncaged-workflow help              # Show all commands
+uncaged-workflow workflow list     # List registered workflows
+uncaged-workflow run <name>        # Start a workflow thread
+uncaged-workflow thread list       # List all threads
+uncaged-workflow thread show <id>  # Inspect a thread
+uncaged-workflow skill             # Agent-consumable reference docs
+```
+
+See `uncaged-workflow help` for the full command reference.
+
+## Development
+
+```bash
+bun run check    # Biome lint + format check
+bun run format   # Auto-format with Biome
+bun test         # Run tests
+```
+
+## Architecture

+
+面向在本仓库中编写 workflow 的 coding agent。引擎层术语与架构细节与 **@uncaged/workflow** 上游文档一致，编写时可对照 \`CLAUDE.md\` 与 \`docs/architecture.md\`。
+
+## 1. 项目结构（workspace / template / workflow instance）
+
+| 层级 | 目录 / 产物 | 职责 |
+|------|----------------|------|
+| **Workspace** | 仓库根（\`package.json\` 含 \`workspaces: ["templates/*", "workflows"]\`） | Bun monorepo：统一管理本地模板包与 workflow 实例 |
+| **Template** | \`templates/<name>/\`（如 \`src/roles.ts\`、\`src/moderator.ts\`、\`src/index.ts\`） | 纯数据：**WorkflowDefinition**（各 **RoleDefinition** + **Moderator**），**不绑定**具体 Agent |
+| **Workflow instance** | \`workflows/\`（或单独包） | 把模板与运行时 **AgentFn** / **ExtractFn** 组合，产出可注册的 **单文件 ESM bundle**（\`run\` + \`descriptor\` 命名导出） |
+
+Init 生成的骨架：\`templates/\` 下放可复用定义，\`workflows/\` 下放绑定与打包入口。
+
+## 2. 核心概念
+
+- **RoleMeta**：\`Record<string, Record<string, unknown>>\`，角色名 → 该角色结构化 meta 的形状约定。
+- **RoleDefinition<Meta>**：纯数据——\`description\`、\`systemPrompt\`、\`extractPrompt\`、\`schema\`（Zod v4）。不含执行逻辑。
+- **WorkflowDefinition<M extends RoleMeta>**：\`description\` + \`roles\`（各角色定义）+ **Moderator**。
+- **Moderator**：\`(ctx: ModeratorContext<M>) => (角色名) | END\`。同步、纯函数，只做路由。
+- **AgentFn**：\`(ctx: AgentContext) => Promise<string>\`，原始文本输出；从上下文读取当前角色的 \`systemPrompt\`。
+- **ExtractFn**：从上下文与 prompt 解析结构化数据（引擎与 Agent 都可使用）。
+
+引擎循环简述：**Moderator** → 选角色 → **Agent** 产出文本 → **Extract** 写入 **meta** → 追加 step，重复直至 **END**。详见 \`docs/architecture.md\` 中的三阶段说明。
+
+## 3. 开发流程
+
+1. **定义 RoleMeta**：为每个角色约定 meta 的 TypeScript 类型（与 Zod schema 对齐）。
+2. **编写 RoleDefinition**：为每个角色写 Zod \`schema\`，补齐 \`systemPrompt\` / \`extractPrompt\` / \`description\`。
+3. **编写 Moderator**：根据 \`ctx.steps\` 与业务状态返回下一个角色名或 \`END\`。
+4. **组装 WorkflowDefinition**：在模板 \`index\` 中导出 definition（以及必要的角色 / moderator 导出）。
+5. **实例化**：在 workflow 包中使用 \`createWorkflow(def, binding, extract)\`（或项目约定的封装）绑定 **AgentFn** / **ExtractFn**。
+6. **构建**：打包为单个 **.esm.js** bundle，使用 **uncaged-workflow add** 注册。
+
+## 4. 编码规范
+
+与 **CLAUDE.md** 对齐，摘要如下：
+
+- **Functional-first**：优先 \`function\` + \`type\`，避免面向对象业务模型。
+- **type 而非 interface**：类型别名一律用 \`type\`，不要使用 \`interface\`。
+- **显式可空**：不要用 \`?:\`；可空字段写成 \`T | null\`。
+- **function 而非 class**：不用 class（第三方库要求或 \`Error\` 子类除外）。
+- **Crockford Base32**：日志 tag、bundle hash、thread id 等标识约定（引擎侧）；工作区内自定义日志若沿用引擎 logger，tag 为 8 字符 Crockford Base32，且每个调用点唯一。
+- **Named exports only**：不要使用 **default export**；workflow bundle 须 **export const run** 与 **export const descriptor**。
+- **No console.log**：库代码用结构化 logger；CLI 用户输出可按项目 Biome 规则例外标注。
+- **No dynamic import**：业务与 bundle 内禁止 \`import()\`；例外仅限「运行时路径由用户提供的 bundle 加载器」（引擎内部）。
+
+## 5. Template 复用
+
+- **已发布模板**：可通过 npm 依赖 \`@uncaged/workflow-template-*\` 等包，在 workflow 实例中 import 其 **WorkflowDefinition** 再绑定 Agent。
+- **本地模板**：放在本仓库 \`templates/<name>/\`，由 workspace 协议引用（如 \`"template-foo": "workspace:*"\` 或相对路径），便于同源修改与版本控制。
+
+选择模板时保持 **definition 与 agent 绑定分离**：模板只描述「做什么、顺序如何」，实例决定「谁执行、如何抽取 meta」。
+
+## 6. Build and Test
+
+日常命令：
+
+\`\`\`sh
+bun install
+bun run check    # Biome：lint + format

+## 7. 常见陷阱
+
+- **No dynamic import**：bundle 须静态可分析；动态 \`import()\` 会破坏哈希与加载约束。
+- **No default export**：引擎只接受命名导出 \`run\` / \`descriptor\`。
+- **No console.log**：避免在可被 Biome \`noConsole\` 规则覆盖的代码路径直接使用 console。
+- **Single-file ESM bundle**：交付物是单一 \`.esm.js\`；静态 import 仅限 Node 内置（见 architecture 文档中的 Bundle Contract）。
+

+
+编写新 workflow 时，先对齐 **RoleMeta → RoleDefinition（Zod）→ Moderator → 绑定 → 单文件 bundle**，再对照本节规范自检。

+| Concept | Description |
+|---------|-------------|
+| **Workflow** | A single-file ESM bundle (\`.esm.js\`) that exports \`run\` and \`descriptor\`. Identified by name and XXH64 hash. |
+| **Bundle** | The physical \`.esm.js\` file stored in the bundles directory. Immutable once written. |
+| **Thread** | A single execution of a workflow, identified by a ULID. Persists state as JSONL files. |
+| **CAS** | Content-Addressable Storage. Per-thread key-value store keyed by content hash. |
+| **Registry** | \`workflow.yaml\` — maps workflow names to their current and historical bundle hashes. |
+
+## Commands
+
+${commandSections.join("\n\n")}
+
+### Top-level shortcuts
+
+| Command | Equivalent | Description |
+|---------|------------|-------------|
+| \`run\` | \`thread run\` | Shortcut to start a thread |
+| \`live\` | \`thread live\` | Shortcut to attach to a thread |
+
+## Typical Workflow
+
+1. \`uncaged-workflow workflow add my-wf ./my-wf.esm.js\` — register a workflow
+2. \`uncaged-workflow run my-wf --prompt "do the thing"\` — start a thread
+3. \`uncaged-workflow live --latest\` — attach and watch output
+4. \`uncaged-workflow thread show <thread-id>\` — inspect completed thread
+
+## Exit Codes
+
+| Code | Meaning |
+|------|---------|
+| 0 | Success |
+| 1 | Error |
+
+## Environment Variables
+
+| Variable | Description |

+Reference for agents executing roles (planner, coder, reviewer, etc.) inside a running workflow thread.
+
+## Thread ID
+
+Every thread has a 26-character Crockford Base32 ULID (e.g. \`06F03H5V6JTMDST6P3TVH42RWM\`).
+
+It appears in the **first message** of the conversation. If unsure:
+
+\`\`\`
+uncaged-workflow thread list
+\`\`\`
+
+## CAS (Content-Addressable Storage)
+
+Store and retrieve content by hash in workflow storage (global CAS directory).
+
+| Operation | Command |
+|-----------|---------|
+| **Store** | \`uncaged-workflow cas put '<content>'\` → prints hash |
+| **Read** | \`uncaged-workflow cas get <HASH>\` → prints content |
+| **List** | \`uncaged-workflow cas list\` |
+
+CAS is the **only** supported way to persist structured data (phase plans, review notes, etc.) within a thread. Do not use temp files.
+
+## Meta Output
+
+Each role must produce structured output that the moderator extracts. The exact schema depends on the role, but the pattern is:
+
+1. Do your work (write code, run tests, etc.)
+2. Output a compact JSON object matching the role's schema
+3. The moderator extracts and validates it automatically
+
+## Thread Context
+
+The conversation history contains outputs from previous roles. Read it to understand:
+- What task was requested (from the initial prompt)
+- What previous roles produced (plans, code changes, review results)
+- What the moderator decided (which phase to work on, whether to retry)

+
+## Bundle Structure
+
+A workflow bundle is a single ESM file (\`.esm.js\`) that exports:
+
+\`\`\`typescript
+// Required exports
+export const descriptor: WorkflowDescriptor;
+export const run: WorkflowRun;
+\`\`\`
+
+## WorkflowDescriptor
+
+Defines the workflow's metadata and role sequence:
+
+\`\`\`typescript
+type WorkflowDescriptor = {
+  name: string;           // verb-first kebab-case, e.g. "solve-issue"
+  description: string;    // one-line summary
+  roles: string[];        // ordered role names, e.g. ["planner", "coder", "reviewer"]
+};
+\`\`\`
+
+## WorkflowRun
+
+The main function that creates and returns a moderator:
+
+\`\`\`typescript
+type WorkflowRun = (ctx: WorkflowContext) => Moderator;
+\`\`\`
+
+The **Moderator** controls the flow — it decides which role runs next, handles retries, and determines when the workflow is complete.
+
+## Role Definition
+
+Each role has:
+
+| Field | Type | Purpose |
+|-------|------|---------|
+| \`description\` | string | What the role does |
+| \`systemPrompt\` | string | System prompt for the agent |
+| \`extractPrompt\` | string | Instruction for extracting structured meta |
+| \`schema\` | ZodSchema | Validates the extracted meta |
+| \`extractRefs\` | fn or null | Extracts CAS hashes from meta for DAG linking |
+| \`extractMode\` | "single" | Extraction mode |
+
+## Development Workflow
+
+\`\`\`bash
+# 1. Initialize a workspace
+uncaged-workflow init workspace my-workflow
+
+# 2. Write your template (roles + moderator + descriptor)
+
+# 3. Build the ESM bundle
+bun run build
+
+# 4. Register locally
+uncaged-workflow workflow add my-workflow ./dist/my-workflow.esm.js
+
+# 5. Test
+uncaged-workflow run my-workflow --prompt "test task"
+uncaged-workflow live --latest
+\`\`\`
+
+## Versioning
+
+Bundles are immutable and identified by XXH64 hash. Re-registering a workflow with a new bundle creates a new version. Use \`workflow history\` and \`workflow rollback\` to manage versions.
