# Skill 系统迁移实施计划

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 将 Neta skill 系统从文档占位状态迁移为完整可用的 prompt-based skill 系统，对齐 OpenClaw + Hermes 架构，支持 GitHub 安装、Node/Python 依赖、渐进式披露、条件激活、前后端完整实现。

**Architecture:** 后端三层服务（SkillLoader 加载/解析 + SkillInstaller 安装/更新 + SkillRegistry 注册/追踪），两个内置工具（read_skill + skill_manage），Controller 改为 @CoolController 混合模式。前端改用 Cool Admin service 代理，重写 skills.vue 和 agent-edit.vue Skill Tab。

**Tech Stack:** Midway.js + TypeORM + js-yaml + child_process(git/npm/uv) | Vue 3 + Element Plus + Cool Admin service 代理 + Socket.IO

**Spec:** `docs/superpowers/specs/2026-04-13-skill-system-migration-design.md`

## File Structure

### 后端 — 新增文件
- `packages/backend/src/modules/netaclaw/service/skill_installer.ts` — GitHub clone + 依赖安装
- `packages/backend/src/modules/netaclaw/service/skill_registry.ts` — lockfile + 指纹 + 来源追踪
- `packages/backend/src/modules/netaclaw/tools/builtin/read_skill.ts` — Agent 按需读取 SKILL.md
- `packages/backend/src/modules/netaclaw/tools/builtin/skill_manage.ts` — Agent 自主 CRUD skill
- `packages/backend/src/modules/netaclaw/service/skill_context.ts` — buildSkillContext 公共函数

### 后端 — 改造文件
- `packages/backend/src/modules/netaclaw/entity/skill.ts` — 移除 icon/category/config，新增 6 字段
- `packages/backend/src/modules/netaclaw/service/skill_loader.ts` — 完全重写
- `packages/backend/src/modules/netaclaw/controller/skill.ts` — @CoolController + 自定义接口
- `packages/backend/src/modules/netaclaw/gateway/server.ts` — 统一 skill 加载逻辑
- `packages/backend/src/modules/netaclaw/controller/chat.ts` — 统一 skill 加载逻辑
- `packages/backend/package.json` — 新增 js-yaml 依赖

### 前端 — 删除文件
- `packages/frontend/src/modules/agent/components/skill-config.vue`
- `packages/frontend/src/modules/agent/components/skill-prompts.vue`
- `packages/frontend/src/modules/agent/components/skill-model.vue`

### 前端 — 改造文件
- `packages/frontend/src/modules/agent/views/skills.vue` — 重写
- `packages/frontend/src/modules/agent/components/skill-detail.vue` — 重写为新详情抽屉
- `packages/frontend/src/modules/agent/views/agent-edit.vue` — Skill Tab 改造

### 数据 — 清理
- 数据库 `netaclaw_skill` 表清空老数据
- `skills/` 目录清空老 skill（保留目录）

---

## Phase 1: 清理与基础

### Task 1: 清理老 skill 数据和依赖准备

**Files:**
- Modify: `packages/backend/package.json`
- Clean: `skills/` 目录
- Clean: 数据库 `netaclaw_skill` 表

- [ ] **Step 1: 安装 js-yaml 依赖**

```bash
cd packages/backend && pnpm add js-yaml && pnpm add -D @types/js-yaml
```

- [ ] **Step 2: 清空 skills 目录下的老 skill**

```bash
cd packages/backend
rm -rf skills/hello-world
# 保留 skills/ 目录本身
mkdir -p skills
```

- [ ] **Step 3: 清空数据库老数据**

```sql
TRUNCATE TABLE netaclaw_skill;
```

- [ ] **Step 4: Commit**

```bash
git add packages/backend/package.json packages/backend/pnpm-lock.yaml
git commit -m "chore: add js-yaml dep, clean old skill data"
```

---

### Task 2: 改造 Skill Entity

**Files:**
- Modify: `packages/backend/src/modules/netaclaw/entity/skill.ts`

- [ ] **Step 1: 重写 skill.ts entity**

将 `packages/backend/src/modules/netaclaw/entity/skill.ts` 完整替换为：

```typescript
import { BaseEntity } from '../../base/entity/base.js';
import { Column, Entity, Index } from 'typeorm';

/**
 * NetaClaw Skill — prompt-based skill 元数据与状态管理
 */
@Entity('netaclaw_skill')
export class NetaClawSkillEntity extends BaseEntity {
  @Column({ comment: 'Skill名称', length: 100, unique: true })
  name: string;

  @Column({ comment: '显示名称', length: 200 })
  label: string;

  @Column({ comment: '描述', type: 'text', nullable: true })
  description: string;

  @Column({ comment: 'Skill类型: compute/llm/multimodal', length: 20, nullable: true })
  skillType: string;

  @Column({ type: 'json', comment: '标签', nullable: true })
  tags: string[];

  @Index()
  @Column({ comment: '状态: 0=禁用 1=启用', default: 1 })
  status: number;

  @Column({ comment: '版本号', length: 20, nullable: true })
  version: string;

  @Column({ comment: '来源: local/github', length: 20, nullable: true })
  source: string;

  @Column({ comment: 'GitHub URL', length: 500, nullable: true })
  sourceUrl: string;

  @Column({ type: 'json', comment: '安装规格 (OpenClaw SkillInstallSpec 兼容)', nullable: true })
  installSpec: Record<string, unknown>[];

  @Column({ type: 'json', comment: '完整 frontmatter 元数据', nullable: true })
  metadata: Record<string, unknown>;

  @Column({ comment: '安装时间', type: 'datetime', nullable: true })
  installedAt: Date;

  @Column({ comment: 'SHA256 内容指纹', length: 64, nullable: true })
  fingerprint: string;
}
```

- [ ] **Step 2: 验证 entity 注册**

确认 `packages/backend/src/entities.ts` 中已有 `NetaClawSkillEntity` 的 import 和注册。无需改动。

- [ ] **Step 3: 启动后端验证表结构自动同步**

```bash
cd packages/backend && pnpm dev
```

检查日志无报错，数据库 `netaclaw_skill` 表字段已更新（老字段 icon/category/config 被移除，新字段 source/sourceUrl/installSpec/metadata/installedAt/fingerprint 已添加）。

- [ ] **Step 4: Commit**

```bash
git add packages/backend/src/modules/netaclaw/entity/skill.ts
git commit -m "refactor: update skill entity - remove old fields, add source/metadata/fingerprint"
```

### Task 8: 改造 Skill Controller

**Files:**
- Modify: `packages/backend/src/modules/netaclaw/controller/skill.ts`

- [ ] **Step 1: 重写 skill controller**

将 `packages/backend/src/modules/netaclaw/controller/skill.ts` 完整替换为：

```typescript
import { Provide, Inject, Get, Post, Body, Query } from '@midwayjs/core';
import { CoolController, BaseController } from '@cool-midway/core';
import { NetaClawSkillEntity } from '../entity/skill.js';

  },
})
export class AdminNetaClawSkillController extends BaseController {
  @Inject()

    try {
      const meta = await this.skillInstaller.installFromGitHub(

    return this.ok(results);
  }

  @Post('/installDeps', { summary: '手动触发依赖安装' })
  async installDeps(@Body() body: { name: string }) {
    try {
      const result = await this.skillInstaller.installDependencies(body.name);

      const realTarget = path.resolve(realSkillsDir, body.name);
      if (!realTarget.startsWith(realSkillsDir)) {
        return this.fail('路径安全检查失败');
      }
      await fs.mkdir(targetDir, { recursive: true });
      await fs.writeFile(path.join(targetDir, 'SKILL.md'), body.content, 'utf-8');
      await this.skillLoader.scanSkills();

  async edit(@Body() body: { name: string; content: string }) {
    return this.create(body); // 逻辑相同：覆盖写入

```

注意：需要在文件顶部补充 import：
```typescript
import * as fs from 'fs/promises';
import * as path from 'path';
```

- [ ] **Step 2: 验证编译**

```bash
cd packages/backend && npx tsc --noEmit
```

### Task 9: 统一 Gateway + Chat Controller 的 skill 加载

**Files:**
- Modify: `packages/backend/src/modules/netaclaw/gateway/server.ts`
- Modify: `packages/backend/src/modules/netaclaw/controller/chat.ts`

- [ ] **Step 1: 改造 gateway/server.ts**

在 `server.ts` 顶部添加 import：
```typescript
import { buildSkillContext } from '../service/skill_context.js';
```

找到构建 agentConfig 的代码块（约第 113-146 行），将 skill 加载逻辑替换为：

```typescript
// 替换原来的:
// const skillNames = agentInfo.skills || [];
// const skillPrompt = this.skillLoader.getSkillPrompt(skillNames);

// 改为（builtinToolNames 从当前已有的工具中提取）:
const builtinToolNames = ['bash', 'read_file', 'write_file', 'list_dir'];
const { skillPrompt, skillTools } = buildSkillContext(
  this.skillLoader,
  agentInfo.skills,
  builtinToolNames,
);
```

在 systemPrompt 拼接处保持不变（已经用 skillPrompt）。

在 `runAgent` 调用处（约第 188 行），将 tools 改为：
```typescript
tools: [bashTool, readFileTool, writeFileTool, listDirTool, ...memoryTools, ...skillTools],
```

- [ ] **Step 2: 改造 chat.ts**

在 `chat.ts` 顶部添加 import：
```typescript
import { buildSkillContext } from '../service/skill_context.js';
```

添加 SkillLoaderService 注入（如果还没有）：
```typescript
@Inject()
skillLoader: SkillLoaderService;
```

找到第 72 行的硬编码空数组：
```typescript
// 替换原来的:
// const skillPrompt = this.skillLoader.getSkillPrompt([]);

// 改为:
const builtinToolNames = ['bash', 'read_file', 'write_file', 'list_dir'];
const { skillPrompt, skillTools } = buildSkillContext(
  this.skillLoader,
  agentEntity?.skills,
  builtinToolNames,
);
```

在 `runAgent` 调用处（约第 106 行），将 tools 改为包含 skillTools：
```typescript
const tools = [bashTool, readFileTool, writeFileTool, listDirTool, ...memoryTools, ...skillTools];
```

- [ ] **Step 3: 验证编译**

```bash
cd packages/backend && npx tsc --noEmit
```

- [ ] **Step 4: 启动后端验证无报错**

```bash
cd packages/backend && pnpm dev
```

- [ ] **Step 5: Commit**

```bash
git add packages/backend/src/modules/netaclaw/gateway/server.ts packages/backend/src/modules/netaclaw/controller/chat.ts
git commit -m "fix: unify skill loading in gateway and chat controller via buildSkillContext"
```

## Phase 3: 前端改造

### Task 10: 删除老组件 + 重写 skills.vue

**Files:**
- Delete: `packages/frontend/src/modules/agent/components/skill-config.vue`
- Delete: `packages/frontend/src/modules/agent/components/skill-prompts.vue`
- Delete: `packages/frontend/src/modules/agent/components/skill-model.vue`
- Modify: `packages/frontend/src/modules/agent/views/skills.vue`

- [ ] **Step 1: 删除老组件**

```bash
rm packages/frontend/src/modules/agent/components/skill-config.vue
rm packages/frontend/src/modules/agent/components/skill-prompts.vue
rm packages/frontend/src/modules/agent/components/skill-model.vue
```

- [ ] **Step 2: 重写 skills.vue**

将 `packages/frontend/src/modules/agent/views/skills.vue` 完整替换。核心改动：
- 所有 `fetch()` 调用改为 `useCool()` 的 service 代理
- 新增安装对话框（GitHub URL 输入）
- 新增卸载/更新操作
- 卡片显示 emoji + source 标签

### Task 11: 重写 skill-detail.vue

**Files:**
- Modify: `packages/frontend/src/modules/agent/components/skill-detail.vue`

- [ ] **Step 1: 重写 skill-detail.vue**

### Task 12: 改造 agent-edit.vue Skill Tab

**Files:**
- Modify: `packages/frontend/src/modules/agent/views/agent-edit.vue`

- [ ] **Step 1: 改造 Skill 配置 Tab**

在 `agent-edit.vue` 中找到 Tab 2（Skill 配置）部分，将其改造为：
- 使用 `service.request` 替代 `fetch`
- 左右布局：可用 skill 列表 + 已选 skill 列表

找到加载 skill 列表的 `fetch` 调用（约第 306-315 行），替换为：
```typescript
async function loadSkillMetas() {
  const { service } = useCool();
  const res = await service.request({ url: '/admin/netaclaw/skill/metas' });
  skillMetas.value = (res || []).filter((s: any) => s.status === 1);
}
```

找到保存 agent 的 `fetch` 调用（约第 410-425 行），替换为：
```typescript
async function saveAgent() {
  const { service } = useCool();
  if (form.value.id) {
    await service.netaclaw.agent.update(form.value);
  } else {
    await service.netaclaw.agent.add(form.value);
  }
}
```

找到加载 agent 详情的 `fetch` 调用（约第 334-378 行），替换为：
```typescript
async function loadAgentInfo(id: number) {
  const { service } = useCool();
  const res = await service.netaclaw.agent.info({ id });
  if (res) {
    Object.assign(form.value, res);
  }
}
```

Skill 选择区域改为带搜索的双列布局：
```vue
<!-- Skill 配置 Tab -->
<div class="skill-select-panel">
  <div class="skill-available">
    <div class="panel-title">可用 Skill</div>
    <el-input v-model="skillSearch" placeholder="搜索..." size="small" clearable style="margin-bottom: 8px" />
    <div v-for="skill in availableSkills" :key="skill.name" class="skill-item" @click="addSkill(skill.name)">
      <span>{{ skill.emoji || '🔧' }} {{ skill.label || skill.name }}</span>
      <el-tag size="small" type="info">{{ skill.skillType || '-' }}</el-tag>
    </div>
  </div>
  <div class="skill-selected">
    <div class="panel-title">已选 Skill ({{ form.skills?.length || 0 }})</div>
    <div v-for="name in (form.skills || [])" :key="name" class="skill-item">
      <span>{{ getSkillLabel(name) }}</span>
      <el-button size="small" type="danger" text @click="removeSkill(name)">移除</el-button>
    </div>
  </div>
</div>
```

- [ ] **Step 2: 验证前端编译**

```bash
cd packages/frontend && pnpm dev
```

在浏览器中访问 `/agent/agents`，点击编辑 Agent，确认 Skill Tab 正常显示。

- [ ] **Step 3: Commit**

```bash
git add packages/frontend/src/modules/agent/views/agent-edit.vue
git commit -m "refactor: agent-edit skill tab - cool admin service proxy, dual-column layout"
```

---

## Phase 4: 集成验证

### Task 13: 端到端验证

- [ ] **Step 1: 创建测试 skill**

在 `packages/backend/skills/` 下创建一个测试 skill：

```bash
mkdir -p packages/backend/skills/test-greeting
```

创建 `packages/backend/skills/test-greeting/SKILL.md`：

```markdown
---
name: test-greeting
description: 测试 Skill - 根据用户姓名生成个性化问候语
version: 1.0.0
metadata:
  skillType: llm
  emoji: "👋"
  tags: [测试, 问候]
  conditions:
    requires_tools: ["bash"]
---

# 问候语生成 Skill

## 何时使用
当用户要求生成问候语或打招呼时使用此 skill。

## 执行流程
1. 获取用户提供的姓名
2. 根据当前时间选择合适的问候方式（早上好/下午好/晚上好）
3. 生成个性化的问候语

## 输出格式
直接返回问候语文本。
```

- [ ] **Step 2: 启动后端，验证 skill 加载**

```bash
cd packages/backend && pnpm dev
```

检查日志应包含：`[SkillLoader] 已加载 Skill: test-greeting`

- [ ] **Step 3: 验证 API 接口**

```bash
# 获取 skill 列表
curl http://localhost:8003/admin/netaclaw/skill/metas -H "Authorization: <token>"

# 获取 skill 内容
curl "http://localhost:8003/admin/netaclaw/skill/content?name=test-greeting" -H "Authorization: <token>"

# 禁用 skill
curl -X POST http://localhost:8003/admin/netaclaw/skill/setStatus \
  -H "Content-Type: application/json" \
  -H "Authorization: <token>" \
  -d '{"name":"test-greeting","status":0}'
```

- [ ] **Step 4: 验证前端页面**

启动前端 `pnpm dev`，访问：
1. `/agent/skills` — 应显示 test-greeting 卡片，可启停/查看详情
2. `/agent/agents` — 编辑 Agent，Skill Tab 应显示 test-greeting 可选

- [ ] **Step 5: 验证 Agent 对话中的 skill 注入**

在 `/agent/chat` 中与配置了 test-greeting skill 的 Agent 对话，检查：
1. System prompt 中应包含 `<available_skills>` XML 索引
2. Agent 应能调用 `read_skill` 工具读取完整内容
3. Agent 应能调用 `skill_manage` 工具创建新 skill

- [ ] **Step 6: 最终 Commit**

```bash
git add packages/backend/skills/test-greeting/
git commit -m "test: add test-greeting skill for e2e verification"
```
