docs(skill): add authoring pitfalls to skill author topic

Add ModeratorTable syntax, AdapterFn/AdapterBinding types, lazy init
pattern, bundle import restrictions, and descriptor requirements.

Knowledge from smoke test discoveries — these are the most common
mistakes when writing workflow bundles.

+# workflow-agent-react — ReAct Agent Package
+
+**Status**: RFC v3
+**Author**: 小橘 🍊
+
+## Problem
+
+现有的 agent 包都依赖外部 CLI 进程：
+
+| Package | 机制 | 能力 |
+|---------|------|------|
+| `workflow-agent-hermes` | spawn `hermes chat` | 完整工具链（文件、终端、浏览器…） |
+| `workflow-agent-cursor` | spawn `cursor-agent` | IDE 级别代码编辑 |
+| `workflow-agent-llm` | 单轮 chat completion | 纯文本，无工具 |
+
+缺少一个 **内置 ReAct agent**：用 LLM + tool calling 循环执行任务，不依赖外部 CLI，工具集由调用方注入。
+
+## 核心设计变更：AdapterFn 替代 AgentFn
+
+### 现状的问题
+
+当前 `AgentFn` 返回 `string`，engine 再用额外一轮 LLM 调用 extract meta：
+
+```
+Agent(ctx) → string → Extract(string, schema) → meta   // 浪费一轮 LLM
+```
+
+### 新抽象：AdapterFn
+
+```typescript
+type RoleFn<T> = (ctx: ThreadContext) => Promise<T>;
+
+type AdapterFn = <T>(prompt: string, schema: z.ZodType<T>) => RoleFn<T>;
+```
+
+- **`prompt`** — role 的 system prompt，描述角色职责和输出要求
+- **`schema`** — role 的 meta schema，定义输出格式
+- **`ThreadContext`** — threadId, depth, bundleHash, start, steps
+
+prompt 和 schema 是一对：prompt 说"你要输出什么"，schema 定义"输出的格式"。它们属于 role definition，由 `createWorkflow` 在每个 role 执行时传给 adapter。
+
+### AgentContext 不再需要
+
+`AgentContext` 在 `ThreadContext` 上扩展了 `currentRole: { name, systemPrompt }`。prompt 现在直接传给 adapter，`AgentContext` 可以删除。
+
+### createWorkflow 签名变更
+
+```typescript
+// Before
+type AgentBinding = {
+  agent: AgentFn;
+  overrides: Partial<Record<string, AgentFn>> | null;
+};
+
+// After
+type AdapterBinding = {
+  adapter: AdapterFn;
+  overrides: Partial<Record<string, AdapterFn>> | null;
+};
+```
+
+engine 对每个 role 的执行逻辑：
+
+```typescript
+// Before
+const result = await agent({ ...threadCtx, currentRole: { name, systemPrompt } });
+const meta = await extract(result, role.metaSchema, provider);  // 额外一轮 LLM
+
+// After
+const roleFn = adapter(role.systemPrompt, role.metaSchema);
+const meta = await roleFn(threadCtx);  // 直接拿到类型安全的 T
+```
+
+## `createReactAdapter` — 复用 workflow-reactor
+
+AdapterFn 的终止条件是"拿到符合 schema 的 T"——和 `workflow-reactor` 的 `ThreadReactorFn` 完全一致。因此 react adapter 是对 reactor 的**薄包装**，不需要自己实现 ReAct 循环。
+
+```typescript
+import { createLlmFn, createThreadReactor } from "@uncaged/workflow-reactor";
+import type { ThreadContext, LlmProvider } from "@uncaged/workflow-protocol";
+import type { ToolDefinition } from "@uncaged/workflow-reactor";
+
+type ReactToolHandler = (name: string, args: string) => Promise<string>;
+
+type ReactAdapterConfig = {
+  provider: LlmProvider;
+  tools: readonly ToolDefinition[];
+  toolHandler: ReactToolHandler;
+  maxRounds: number;
+};
+
+function createReactAdapter(config: ReactAdapterConfig): AdapterFn {
+  return <T>(prompt: string, schema: z.ZodType<T>) => {
+    const reactor = createThreadReactor<ThreadContext>({
+      llm: createLlmFn(config.provider),
+      staticTools: config.tools,
+      structuredToolFromSchema: (s) => buildStructuredTool(s),
+      systemPromptForStructuredTool: () => prompt,
+      toolHandler: (call, ctx) =>
+        config.toolHandler(call.function.name, call.function.arguments),
+      maxRounds: config.maxRounds,
+    });
+
+    return async (ctx: ThreadContext): Promise<T> => {
+      const input = buildThreadInput(ctx);
+      const result = await reactor({ thread: ctx, input, schema });
+      if (!result.ok) throw new Error(result.error);
+      return result.value;
+    };
+  };
+}
+```
+
+整个包就是：**一个工厂函数 + 类型定义 + thread 输入构造**。
+
+## `agentToAdapter` — 向后兼容
+
+把现有 `AgentFn`（hermes/cursor）包装成 `AdapterFn`：
+
+```typescript
+function agentToAdapter(agent: AgentFn, extractProvider: LlmProvider): AdapterFn {
+  return <T>(prompt: string, schema: z.ZodType<T>): RoleFn<T> => {
+    return async (ctx: ThreadContext): Promise<T> => {
+      const agentCtx = { ...ctx, currentRole: { name: "agent", systemPrompt: prompt } };
+      const result = await agent(agentCtx);
+      const output = typeof result === "string" ? result : result.output;
+      return extract(output, schema, extractProvider);
+    };
+  };
+}
+```
+
+hermes/cursor agent 内部不改，bundle-entry 层多包一层即可。
+
+## 包结构
+
+```
+packages/workflow-agent-react/
+  src/
+    types.ts                 # ReactAdapterConfig, ReactToolHandler
+    create-react-adapter.ts  # AdapterFn 工厂（包装 reactor）
+    thread-input.ts          # ThreadContext → user message string
+    index.ts
+  __tests__/
+    create-react-adapter.test.ts
+  package.json
+```
+
+依赖：
+- `@uncaged/workflow-protocol` — `ThreadContext`, `LlmProvider`
+- `@uncaged/workflow-reactor` — `createLlmFn`, `createThreadReactor`, types
+
+## 影响范围
+
+### Breaking Changes
+
+| 改动 | 影响 |
+|------|------|
+| `AgentBinding` → `AdapterBinding` | `createWorkflow` 调用方（所有 bundle-entry） |
+| `AgentContext` 删除 | `buildAgentPrompt`（util-agent）改为接收 `ThreadContext` |
+| extract 从 engine 下沉到 adapter | `workflow-execute` 简化 |
+
+### 需修改的包
+
+1. `workflow-protocol` — 删除 `AgentContext`/`AgentFn`/`AgentFnResult`/`AgentBinding`，新增 `AdapterFn`/`RoleFn`/`AdapterBinding`
+2. `workflow-runtime` — 更新 re-export
+3. `workflow-execute` — engine 调用 `adapter(prompt, schema)` 替代 `agent(ctx) + extract`
+4. `workflow-util-agent` — `buildAgentPrompt` → `buildThreadInput`，接收 `ThreadContext`
+5. 所有 bundle-entry — `agent:` → `adapter:`
+
+### 不受影响
+
+- `workflow-cas` / `workflow-register` / `workflow-reactor` / `workflow-dashboard`
+- `workflow-agent-hermes` / `workflow-agent-cursor`（内部不改，外部用 `agentToAdapter` 包装）
+
+## Phases
+
+1. **Phase 1**: protocol 类型 + `createWorkflow` 签名变更 + `agentToAdapter`
+2. **Phase 2**: `workflow-agent-react` 包（包装 reactor）
+3. **Phase 3**: 工具集实现（read/write/patch/shell） + smoke test 闭环
+
+## 工具集（后续讨论）
+
+| 工具 | 说明 | 优先级 |
+|------|------|--------|
+| `read_file` | 读文件 | P0 |
+| `write_file` | 写文件 | P0 |
+| `patch_file` | find-and-replace 编辑 | P0 |
+| `shell_exec` | 执行 shell 命令 | P0 |
+| `search_files` | grep / find | P1 |
+| `list_files` | ls | P1 |

 ## 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.
+
+## Pitfalls
+
+### Lazy initialization is mandatory
+
+The bundle is \`import()\`-ed at register time (\`workflow add\`) to read the descriptor. At that point, no runtime env vars (API keys, etc.) are available.
+
+**Never read env at module top-level.** Wrap provider/adapter creation in a lazy closure:
+
+\`\`\`typescript
+// ❌ WRONG — breaks register
+const provider = { apiKey: process.env.MY_KEY! };
+const adapter = createAdapter(provider);
+
+// ✅ CORRECT — only reads env when run() is called
+function createLazyAdapter(): AdapterFn {
+  let cached: Provider | null = null;
+  return (prompt, schema) => {
+    return async (ctx, runtime) => {
+      if (!cached) cached = { apiKey: process.env.MY_KEY! };
+      // ... use cached provider
+    };
+  };
+}
+\`\`\`
+
+### Bundle import restrictions
+
+The bundle validator only allows these import specifiers:
+- Node built-ins (\`node:fs\`, \`node:path\`, etc.)
+- \`@uncaged/workflow-*\` packages
+
+Third-party packages (**including zod**) must be bundled into the \`.esm.js\` file, not left as external imports. When using \`bun build\`, only mark \`@uncaged/*\` as external.
+
+### No default exports
+
+The engine only reads named exports \`run\` and \`descriptor\`. Using \`export default\` will cause registration to fail silently.
+
+### Single-file ESM
+
+The bundle must be a single \`.esm.js\` file. No dynamic \`import()\` inside the bundle — it breaks hash verification and the loader sandbox.
