# projects-meta-mcp Bootstrap Implementation Plan

> **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:** Реализовать `sync-script` (Gitea API → JSON-кэш) и stdio MCP-сервер с тулами `tasks.*`, `knowledge.*`, `meta.status` — согласно спеке [2026-04-29-projects-meta-mcp-design.md](../specs/2026-04-29-projects-meta-mcp-design.md). Конечное состояние: после `npm run build` и `node dist/sync.js` локальный `~/.cache/projects-mcp/tasks.json` содержит реальные `STATUS.md` всех проектов owner'a `OpeItcLoc03`, `node dist/server.js` стартует stdio MCP и отвечает на все определённые tools.

**Architecture:** Один TS-пакет, два бинарника: `dist/sync.js` (CLI, делает сетевые вызовы) и `dist/server.js` (MCP stdio, читает только локальные файлы). Общая логика (парсеры, конфиг, кэш) — в `src/lib/`. ESM (`"type": "module"`), TypeScript NodeNext, native fetch.

**Tech Stack:** Node 22, TypeScript 5, `@modelcontextprotocol/sdk`, `gray-matter` (frontmatter), `smol-toml` (auth.toml), `zod` (схемы tool-инпутов), `vitest` (тесты).

**File size discipline:** `lib/` files ≤ 150 lines each. Если файл вырастает — split.

**Commits:** один TDD-цикл (test → impl → green → commit) = один коммит. Сообщения в Conventional Commits, scope = file/module.

## Phase 1 — Bootstrap

### Task 1.1: Initialize npm package + TypeScript

**Files:**
- Create: `package.json`
- Create: `tsconfig.json`
- Create: `vitest.config.ts`
- Create: `src/sync.ts` (skeleton)
- Create: `src/server.ts` (skeleton)

- [ ] **Step 1: Create package.json**

```json
{
  "name": "projects-meta-mcp",
  "version": "0.1.0",
  "private": true,
  "type": "module",
  "bin": {
    "projects-meta-mcp": "dist/server.js",
    "projects-meta-sync": "dist/sync.js"
  },
  "scripts": {
    "build": "tsc",
    "start": "node dist/server.js",
    "sync": "node dist/sync.js",
    "test": "vitest run",
    "test:watch": "vitest",
    "typecheck": "tsc --noEmit"
  },
  "dependencies": {
    "@modelcontextprotocol/sdk": "^1.0.0",
    "gray-matter": "^4.0.3",
    "smol-toml": "^1.3.0",
    "zod": "^3.23.0"
  },
  "devDependencies": {
    "@types/node": "^22.0.0",
    "typescript": "^5.6.0",
    "vitest": "^2.1.0"
  },
  "engines": {
    "node": ">=22"
  }
}
```

- [ ] **Step 2: Create tsconfig.json**

```json
{
  "compilerOptions": {
    "target": "ES2023",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "lib": ["ES2023"],
    "outDir": "dist",
    "rootDir": "src",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "declaration": false,
    "sourceMap": true,
    "resolveJsonModule": true,
    "verbatimModuleSyntax": true
  },
  "include": ["src/**/*"],
  "exclude": ["dist", "node_modules", "tests"]
}
```

- [ ] **Step 3: Create vitest.config.ts**

```ts
import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    include: ['tests/**/*.test.ts'],
    environment: 'node',
  },
});
```

- [ ] **Step 4: Create src/sync.ts and src/server.ts skeletons**

`src/sync.ts`:
```ts
async function main(): Promise<void> {
  console.log('sync: not implemented yet');
}

await main();
```

`src/server.ts`:
```ts
async function main(): Promise<void> {
  console.error('server: not implemented yet');
}

await main();
```

- [ ] **Step 5: Run `npm install`**

Run: `npm install`
Expected: `node_modules/` populated, `package-lock.json` created, no errors.

- [ ] **Step 6: Verify build works**

Run: `npm run build && node dist/sync.js && node dist/server.js`
Expected: skeleton outputs without crash. `dist/` contains `.js` files.

- [ ] **Step 7: Add dist/ and node_modules to .gitignore (already there)**

Verify `.gitignore` already contains `node_modules/` and `dist/`. If not, add.

- [ ] **Step 8: Commit**

```bash
git add package.json package-lock.json tsconfig.json vitest.config.ts src/sync.ts src/server.ts
git commit -m "chore: scaffold TS package with sync + server entries"
```

---

### Task 1.2: Auth example + cache dir convention

**Files:**
- Create: `auth.toml.example`

- [ ] **Step 1: Create auth.toml.example**

```toml
# projects-meta-mcp auth config
# Copy to ~/.config/projects-mcp/auth.toml and fill gitea_token.

gitea_url   = "https://git.kzntsv.site"
gitea_user  = "OpeItcLoc03"
gitea_token = "REPLACE_WITH_PERSONAL_ACCESS_TOKEN"  # scope: read:repository
```

- [ ] **Step 2: Commit**

```bash
git add auth.toml.example
git commit -m "chore: add auth.toml.example"
```

---

## Phase 2 — sync-script

### Task 2.1: Config loader

**Files:**
- Create: `src/lib/config.ts`
- Create: `tests/lib/config.test.ts`

**Contract:**
```ts
export interface AuthConfig {
  giteaUrl: string;       // no trailing slash
  giteaUser: string;
  giteaToken: string;
}

export interface Paths {
  cacheDir: string;       // ~/.cache/projects-mcp
  cacheFile: string;      // <cacheDir>/tasks.json
  syncLog: string;        // <cacheDir>/sync.log
  authFile: string;       // ~/.config/projects-mcp/auth.toml

    const dir = await mkdtemp(join(tmpdir(), 'auth-'));
    const file = join(dir, 'auth.toml');
    await writeFile(
      file,

    );
    const cfg = await loadAuth(file);
    expect(cfg.giteaUrl).toBe('https://git.kzntsv.site');
  });

  it('throws on missing field', async () => {
    const dir = await mkdtemp(join(tmpdir(), 'auth-'));
    const file = join(dir, 'auth.toml');
    await writeFile(file, 'gitea_url = "x"\ngitea_user = "y"\n');
    await expect(loadAuth(file)).rejects.toThrow(/gitea_token/);
  });

    cacheFile: join(cacheDir, 'tasks.json'),
    syncLog: join(cacheDir, 'sync.log'),
    authFile: join(home, '.config', 'projects-mcp', 'auth.toml'),
    sharedWikiClone: join(home, 'projects', '.wiki'),
  };
}

const AuthSchema = z.object({
  gitea_url: z.string().min(1),
  gitea_user: z.string().min(1),
  gitea_token: z.string().min(1),
});

export async function loadAuth(authFile: string): Promise<AuthConfig> {
  const raw = await readFile(authFile, 'utf8');
  const parsed = AuthSchema.parse(parseToml(raw));
  return {
    giteaUrl: parsed.gitea_url.replace(/\/+$/, ''),
    giteaUser: parsed.gitea_user,
    giteaToken: parsed.gitea_token,

## Phase 3 — MCP server core

### Task 3.1: Server bootstrap (stdio + tool registry)

**Files:**
- Modify: `src/server.ts` (replace skeleton)

The MCP SDK exposes `Server` and `StdioServerTransport`. Tools are registered in handlers. The server reads `process.argv[2]` if given as `--cwd <path>` for explicit cwd-override; otherwise uses `process.cwd()`.

- [ ] **Step 1: Replace src/server.ts**

```ts
import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
import {
  CallToolRequestSchema,
  ListToolsRequestSchema,
} from '@modelcontextprotocol/sdk/types.js';
import { homedir } from 'node:os';
import { getPaths } from './lib/config.js';
import { makeTasksTools } from './tools/tasks.js';
import { makeKnowledgeTools } from './tools/knowledge.js';
import { makeMetaTools } from './tools/meta.js';

function getCwdArg(): string {
  const i = process.argv.indexOf('--cwd');
  if (i >= 0 && process.argv[i + 1]) return process.argv[i + 1];
  return process.cwd();
}

async function main(): Promise<void> {
  const paths = getPaths(homedir());
  const cwd = getCwdArg();

  const tools = [
    ...makeTasksTools({ cacheFile: paths.cacheFile }),
    ...makeKnowledgeTools({ wikiRoot: paths.sharedWikiClone, projectCwd: cwd }),
    ...makeMetaTools({ paths }),
  ];

  const byName = new Map(tools.map((t) => [t.name, t]));

  const server = new Server(
    { name: 'projects-meta-mcp', version: '0.1.0' },
    { capabilities: { tools: {} } },
  );

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: tools.map((t) => ({
      name: t.name,
      description: t.description,
      inputSchema: t.inputSchema,
    })),
  }));

  server.setRequestHandler(CallToolRequestSchema, async (req) => {
    const tool = byName.get(req.params.name);
    if (!tool) {
      return {
        content: [{ type: 'text', text: `Unknown tool: ${req.params.name}` }],
        isError: true,
      };
    }
    return await tool.handler(req.params.arguments ?? {});
  });

  const transport = new StdioServerTransport();
  await server.connect(transport);
}

await main();
```

- [ ] **Step 2: Define ToolDef shape**

Create `src/tools/types.ts`:

```ts
export interface ToolResult {
  content: Array<{ type: 'text'; text: string }>;
  isError?: boolean;
}

export interface ToolDef {
  name: string;
  description: string;
  inputSchema: {
    type: 'object';
    properties?: Record<string, unknown>;
    required?: string[];
    additionalProperties?: boolean;
  };
  handler: (args: Record<string, unknown>) => Promise<ToolResult>;
}
```

- [ ] **Step 3: Stub the three tool factories so build passes**

Create empty stubs (real impl in later tasks). Each returns `[]`.

`src/tools/tasks.ts`:
```ts
import type { ToolDef } from './types.js';

export function makeTasksTools(_opts: { cacheFile: string }): ToolDef[] {
  return [];
}
```

`src/tools/knowledge.ts`:
```ts
import type { ToolDef } from './types.js';

export function makeKnowledgeTools(_opts: {
  wikiRoot: string;
  projectCwd: string;
}): ToolDef[] {
  return [];
}
```

`src/tools/meta.ts`:
```ts
import type { ToolDef } from './types.js';
import type { Paths } from '../lib/config.js';

export function makeMetaTools(_opts: { paths: Paths }): ToolDef[] {
  return [];
}
```

- [ ] **Step 4: Build**

Run: `npm run build`
Expected: no errors.

- [ ] **Step 5: Commit**

```bash
git add src/server.ts src/tools/types.ts src/tools/tasks.ts src/tools/knowledge.ts src/tools/meta.ts
git commit -m "feat(server): stdio bootstrap + tool registry skeleton"
```

---

### Task 3.2: Tasks tools (`tasks.aggregate`, `tasks.search`, `tasks.get`)

**Files:**
- Modify: `src/tools/tasks.ts`
- Create: `tests/tools/tasks.test.ts`

**Contracts:**
- `tasks.aggregate({ status?, project? })` → list of `{ project, slug, status, description, next }` filtered by both. No raw text.
- `tasks.search({ query })` → matches `query` (case-insensitive substring) against `slug + description + next`. Returns same shape as aggregate.
- `tasks.get({ project })` → returns full STATUS.md raw of one project.

- [ ] **Step 1: Write failing tests**

`tests/tools/tasks.test.ts`:

### Task 3.3: Domain detector

**Files:**
- Create: `src/lib/domain-detector.ts`

**Contract:**
```ts
export type Domain = 'node' | 'embedded' | 'web' | 'unknown';
export async function detectDomain(cwd: string): Promise<Domain>;
```

Decision rules (spec §detect domain):
1. `package.json` exists → `node`
2. `platformio.ini` OR any `*.ino` OR `CMakeLists.txt` containing `arm-none-eabi` or `STM32` or `ESP_IDF` → `embedded`
3. `next.config.*` OR `vite.config.*` OR (`index.html` AND no `package.json`) → `web`
4. else → `unknown`

- [ ] **Step 1: Write failing tests**

### Task 3.4: Knowledge tools (`knowledge.search`, `knowledge.get`)

**Files:**
- Create: `src/lib/wiki-index.ts`
- Modify: `src/tools/knowledge.ts`
- Create: `tests/lib/wiki-index.test.ts`
- Create: `tests/tools/knowledge.test.ts`

**Contract for wiki-index:**
```ts
export interface WikiPage {
  slug: string;          // path relative to wikiRoot, no .md extension, e.g. "node/windows-yarn"
  title: string;
  domain: string;        // from frontmatter
  tags: string[];
  body: string;          // body text only (no frontmatter)
  raw: string;           // full file contents
}

export async function loadWiki(root: string): Promise<WikiPage[]>;
```

Walk all `*.md` files except `CLAUDE.md` and `README.md` at root level (those are wiki meta). Skip pages without `domain:` frontmatter (warn but include with `domain="unknown"`).

**Contract for knowledge tools:**
- `knowledge.search({ query, domain?, limit? })` → list of `{ slug, title, snippet, domain }`. Default `limit=10`. Default domain filter = detected from cwd; if cwd domain is `unknown` no filter; if `domain="all"` no filter; otherwise show pages where `domain == filter || domain == "cross"`.

### Task 3.5: Meta tools (`meta.status`)

**Files:**
- Modify: `src/tools/meta.ts`
- Create: `tests/tools/meta.test.ts`

**Contract:**
```
meta.status() → { synced_at, age_seconds, projects_count, errors_count, cache_path, wiki_root, wiki_pages_count, stale: boolean }

### Task 3.6: Promotion candidate tool (`knowledge.suggest_promote`)

**Files:**
- Create: `src/lib/promotion.ts`
- Create: `tests/lib/promotion.test.ts`
- Modify: `src/tools/knowledge.ts` (add tool)
- Modify: `tests/tools/knowledge.test.ts` (extend tests)

**Heuristic** (per spec §knowledge.suggest_promote):
- INCLUDE if page mentions any platform/tooling keyword: `Windows`, `Linux`, `macOS`, `yarn`, `npm`, `Node`, `MCP`, `git`, `Docker`, `tsx`, `vite`, `webpack`, `pnpm`.
- EXCLUDE if page mentions any project name from a configured blacklist (passed in opts).
- BOOST confidence if `projects-wiki` already has a page with similar title in any domain (jaccard ≥ 0.4 on tokenized title).
- Returned shape per candidate: `{ slug, current_path, suggested_domain, confidence, reason }`. `suggested_domain` derived from cwd domain (or `cross` if unknown).

**Contract:**
```ts
export interface PromotionCandidate {
  slug: string;
  current_path: string;
  suggested_domain: string;
  confidence: 'low' | 'medium' | 'high';
  reason: string;
}

- [ ] **Step 4: Run promotion tests, expect PASS**

Run: `npm test -- tests/lib/promotion.test.ts`
Expected: 5 passed.

- [ ] **Step 5: Add knowledge.suggest_promote to src/tools/knowledge.ts**

Insert this tool after `knowledge.get` in the returned array of `makeKnowledgeTools`:

```ts
{
  name: 'knowledge.suggest_promote',
  description:
    'Возвращает кандидатов из текущего .wiki/concepts/ на промоушен в projects-wiki. Фильтр по платформенным ключам, исключение по чёрному списку проектов. Решение всегда у пользователя — этот tool не пишет файлы.',
  inputSchema: { type: 'object', properties: {}, additionalProperties: false },

      sharedPages: shared,
      cwdDomain: det,

},
```

Add imports at top of `src/tools/knowledge.ts`:
```ts
import { join } from 'node:path';
import { findCandidates } from '../lib/promotion.js';
```

- [ ] **Step 6: Extend tests/tools/knowledge.test.ts with one suggest_promote test**

Append to the file:

```

- [ ] **Step 7: Run all knowledge tests**

Run: `npm test -- tests/tools/knowledge.test.ts tests/lib/promotion.test.ts`
Expected: all pass.

- [ ] **Step 8: Commit**

```bash
git add src/lib/promotion.ts tests/lib/promotion.test.ts src/tools/knowledge.ts tests/tools/knowledge.test.ts
git commit -m "feat(promotion): suggest_promote tool with keyword + similarity heuristic"
```

---

## Phase 4 — Wiring & smoke

### Task 4.1: Build + run all tests

- [ ] **Step 1: Full typecheck + build**

Run: `npm run typecheck && npm run build`
Expected: zero errors. `dist/sync.js` and `dist/server.js` produced.

- [ ] **Step 2: Full test suite**

Run: `npm test`
Expected: every test from previous tasks PASS, no failures.

- [ ] **Step 3: Smoke-run sync without auth (expect graceful failure)**

Run: `node dist/sync.js`
Expected: exit code 2 with message `auth.toml load failed: ...` (auth.toml absent on CI/dev box).

This is the desired graceful behavior; do not commit a fix.

- [ ] **Step 4: Smoke-run server with stub stdin**

Run (Windows PowerShell):
```powershell
echo '' | node dist/server.js
```

Expected: process stays alive a moment, exits cleanly when stdin closes. No stack traces.

- [ ] **Step 5: Commit any incidental fixes (probably none)**

If fixes were needed, commit them now. Otherwise skip.

---

### Task 4.2: Update README + record tasks

**Files:**
- Modify: `README.md`
- Modify: `.tasks/STATUS.md`
- Create: `.tasks/bootstrap-implementation.md`
- Modify: `.wiki/index.md`
- Modify: `.wiki/log.md`
- Create: `.wiki/entities/sync-script.md`
- Create: `.wiki/entities/mcp-server.md`
- Create: `.wiki/entities/domain-detector.md`
- Create: `.wiki/packages/modelcontextprotocol-sdk.md`
- Create: `.wiki/packages/gray-matter.md`
- Create: `.wiki/packages/smol-toml.md`
- Create: `.wiki/packages/zod.md`

- [ ] **Step 1: Replace README.md**

```markdown
# projects-meta-mcp

MCP-сервер: агрегирует статусы задач (`.tasks/STATUS.md`) и общие знания (репо `projects-wiki`, локально клонится в `~/projects/.wiki/`) поверх множества проектов и нескольких машин.

- Источник правды: Gitea (`https://git.kzntsv.site`, owner `OpeItcLoc03`).
- Процесс — локальный на каждой машине (offline-критично).
- Данные — локальный кэш + клон `projects-wiki`, синхронизируются скриптом.

## Bootstrap

```bash
git clone https://git.kzntsv.site/OpeItcLoc03/projects-meta-mcp ~/.local/projects-meta-mcp
cd ~/.local/projects-meta-mcp
npm install && npm run build

git clone https://git.kzntsv.site/OpeItcLoc03/projects-wiki ~/projects/.wiki

mkdir -p ~/.config/projects-mcp
cp auth.toml.example ~/.config/projects-mcp/auth.toml
# отредактировать auth.toml — заполнить gitea_token

node dist/sync.js   # первый sync
```

## Регистрация в Claude Code

Добавить в `~/.claude.json`:

```json
{
  "mcpServers": {
    "projects-meta": {
      "command": "node",
      "args": ["C:/Users/<USER>/.local/projects-meta-mcp/dist/server.js"]
    }
  }
}
```

## Tools

| Tool | Назначение |
|------|------------|
| `tasks.aggregate` | Свод активных задач по всем проектам |
| `tasks.search` | Поиск по slug/next-action |
| `tasks.get` | Полный STATUS.md одного проекта |
| `knowledge.search` | Поиск по shared-вики, фильтр по домену cwd |
| `knowledge.get` | Полный текст одной страницы |
| `knowledge.suggest_promote` | Кандидаты на промоушен из `.wiki/concepts/` текущего проекта |
| `meta.status` | Возраст кэша + диагностика |

См. дизайн: [docs/superpowers/specs/2026-04-29-projects-meta-mcp-design.md](docs/superpowers/specs/2026-04-29-projects-meta-mcp-design.md)
План реализации: [docs/superpowers/plans/2026-04-29-bootstrap-implementation.md](docs/superpowers/plans/2026-04-29-bootstrap-implementation.md)
```

- [ ] **Step 2: Add task block to .tasks/STATUS.md**

After the comment block, append:

```markdown

## 🟢 [bootstrap-implementation] — Реализация sync-script + MCP-сервера по спеке

**Status:** done
**Where I stopped:** Все фазы плана выполнены, тесты зелёные, README обновлён.
**Next action:** Юзкейс-проверка на реальной Gitea: положить `auth.toml`, запустить `node dist/sync.js`, дёрнуть MCP из Claude Code.
**Branch:** main

---
```

- [ ] **Step 3: Create .tasks/bootstrap-implementation.md**

```markdown
# bootstrap-implementation

## Goal
Реализовать минимальный рабочий `projects-meta-mcp`: sync-script тащит `STATUS.md` всех репо `OpeItcLoc03` через Gitea API в локальный JSON-кэш; MCP-сервер по stdio отдаёт `tasks.*`, `knowledge.*`, `meta.status`. Конец = `npm test` зелёный, `npm run build` успешен, README с bootstrap-инструкцией.

## Key files
- `src/sync.ts` — CLI sync entry
- `src/server.ts` — MCP stdio entry
- `src/lib/config.ts:1` — paths + auth.toml
- `src/lib/gitea.ts:1` — Gitea API wrapper
- `src/lib/sync-runner.ts:1` — orchestrator (concurrency, error-collect)
- `src/lib/status-md.ts:1` — STATUS.md parser
- `src/lib/wiki-index.ts:1` — projects-wiki page loader
- `src/lib/domain-detector.ts:1` — cwd domain heuristic
- `src/lib/promotion.ts:1` — suggest_promote heuristic
- `src/tools/{tasks,knowledge,meta}.ts` — tool factories

## Decisions log
- 2026-04-29: ESM (`"type": "module"`) + NodeNext — ради native fetch и top-level await.
- 2026-04-29: Vitest вместо jest — нативный ESM, быстрее.
- 2026-04-29: `gray-matter` для frontmatter, `smol-toml` для auth.toml, `zod` для tool input validation.
- 2026-04-29: Concurrency limit 10 для Gitea — соответствует спеке.
- 2026-04-29: Stale threshold 24h в `meta.status` — соответствует спеке.

## Open questions
- [ ] Нужно ли в `getRawFile` пытаться `master` если `default_branch` не сработал? (пока: только `default_branch`).
- [ ] Cron / git-hook для запуска sync — вне scope этого таска.

## Completed steps
- [x] Phase 1 — bootstrap (package.json, tsconfig, vitest, auth.toml.example)
- [x] Phase 2 — sync (config, cache, status-md, gitea, sync-runner, sync.ts)
- [x] Phase 3 — server (stdio, tasks tools, domain-detector, knowledge tools, meta, promotion)
- [x] Phase 4 — wiring (README, .tasks, .wiki entities/packages)

## Notes
Pre-merge проверка: положить `~/.config/projects-mcp/auth.toml` с реальным токеном, запустить `node dist/sync.js`, проверить `~/.cache/projects-mcp/tasks.json`. Затем зарегистрировать MCP в `~/.claude.json` и дёрнуть `meta.status` из Claude Code.
```

- [ ] **Step 4: Update .wiki/index.md**

Replace `_Пусто. Появятся при реализации сервера._` and `_Пусто. Появятся при `npm install` зависимостей._` with:

```markdown
## Сущности

- [sync-script](entities/sync-script.md) — скрипт-синк Gitea API → JSON-кэш.
- [mcp-server](entities/mcp-server.md) — stdio MCP с тулами `tasks.*`, `knowledge.*`, `meta.*`.
- [domain-detector](entities/domain-detector.md) — определение домена cwd по файлам.

## Пакеты

- [@modelcontextprotocol/sdk](packages/modelcontextprotocol-sdk.md) — MCP runtime.
- [gray-matter](packages/gray-matter.md) — frontmatter parser.
- [smol-toml](packages/smol-toml.md) — TOML parser для auth.toml.
- [zod](packages/zod.md) — runtime валидация tool-инпутов.
```

- [ ] **Step 5: Create .wiki/entities/sync-script.md**

```markdown
---
title: sync-script
type: entity
tags: [gitea, cache, cli]
sources: []
updated: 2026-04-29
---

# sync-script

Локальный CLI-скрипт. Тащит `STATUS.md` всех репо пользователя через Gitea API, парсит, складывает в `~/.cache/projects-mcp/tasks.json` атомарной записью.

## Файлы

- [src/sync.ts](../../src/sync.ts) — entrypoint, читает `auth.toml`, вызывает runner, пишет кэш и лог.
- [src/lib/sync-runner.ts](../../src/lib/sync-runner.ts) — pure orchestrator: `listUserRepos` → параллельно (concurrency=10) `getRawFile` + `parseStatusMd` → собирает `CacheFile`. Тестируется юнитами через моки.
- [src/lib/gitea.ts](../../src/lib/gitea.ts) — fetch-wrapper, пагинация, 404 → `null`.
- [src/lib/cache.ts](../../src/lib/cache.ts) — атомарная запись через `tasks.json.tmp` + `rename`.

## Контракт

`runSync({ client, parseStatus, now, machine, giteaUrl, user, concurrency? })` → `CacheFile`.

Ошибки сетевых запросов на конкретный репо не валят весь синк — оседают в `errors[]`. 404 на `STATUS.md` = у проекта нет тасок (skip без ошибки).

## Запуск

```bash
node dist/sync.js
```

Exit codes:
- `0` — sync прошёл (даже с частичными ошибками).
- `2` — `auth.toml` отсутствует / битый.
```

- [ ] **Step 6: Create .wiki/entities/mcp-server.md**

```markdown
---
title: mcp-server
type: entity
tags: [mcp, stdio]
sources: []
updated: 2026-04-29
---

# mcp-server

stdio MCP-сервер. Не делает сетевых вызовов в hot path. Читает локальный кэш и клон `projects-wiki`.

## Tools

| Name | Файл |
|------|------|
| `tasks.aggregate`, `tasks.search`, `tasks.get` | [src/tools/tasks.ts](../../src/tools/tasks.ts) |
| `knowledge.search`, `knowledge.get`, `knowledge.suggest_promote` | [src/tools/knowledge.ts](../../src/tools/knowledge.ts) |
| `meta.status` | [src/tools/meta.ts](../../src/tools/meta.ts) |

## CLI args

- `--cwd <path>` — переопределение cwd (для тестов и nonstandard launchers). Иначе `process.cwd()`.

## Запуск

```bash
node dist/server.js
```

Транспорт — stdio. Регистрируется в `~/.claude.json` как `mcpServers.projects-meta`.
```

- [ ] **Step 7: Create .wiki/entities/domain-detector.md**

```markdown
---
title: domain-detector
type: entity
tags: [heuristic]
sources: []
updated: 2026-04-29
---

# domain-detector

Определяет домен текущего проекта по файлам в cwd. Используется `knowledge.search` для дефолтного фильтра и `knowledge.suggest_promote` для предлагаемого `domain` в кандидате.

## Алгоритм

1. `package.json` → `node`
2. `platformio.ini` / `*.ino` / `CMakeLists.txt` с `arm-none-eabi`/`STM32`/`ESP_IDF` → `embedded`
3. `next.config.*` / `vite.config.*` / `index.html` (без package.json) → `web`
4. иначе → `unknown`

`package.json` имеет высший приоритет — node-проект со статиком всё равно `node`.

## Файл

- [src/lib/domain-detector.ts](../../src/lib/domain-detector.ts) — pure async function. Тесты — [tests/lib/domain-detector.test.ts](../../tests/lib/domain-detector.test.ts).
```

- [ ] **Step 8: Create package pages**

`.wiki/packages/modelcontextprotocol-sdk.md`:
```markdown
---
title: "@modelcontextprotocol/sdk"
type: package
tags: [mcp, runtime]
updated: 2026-04-29
---

# @modelcontextprotocol/sdk

Официальный TypeScript SDK для MCP. Используется только в [src/server.ts](../../src/server.ts).

- `Server` + `StdioServerTransport` для stdio-режима.
- Хендлеры регистрируются через `setRequestHandler(ListToolsRequestSchema | CallToolRequestSchema, ...)`.
- Для входных схем тулов используется JSON Schema (objects). Runtime-валидация — наша через `zod`.
```

`.wiki/packages/gray-matter.md`:
```markdown
---
title: gray-matter
type: package
tags: [yaml, frontmatter]
updated: 2026-04-29
---

# gray-matter

Парсит YAML frontmatter в markdown. Используется в:
- [src/lib/wiki-index.ts](../../src/lib/wiki-index.ts) — `loadWiki()`
- [src/lib/promotion.ts](../../src/lib/promotion.ts) — `findCandidates()`

API: `matter(text) → { data, content }`.
```

`.wiki/packages/smol-toml.md`:
```markdown
---
title: smol-toml
type: package
tags: [toml]
updated: 2026-04-29
---

# smol-toml

TOML парсер без зависимостей. Используется в [src/lib/config.ts](../../src/lib/config.ts) для `~/.config/projects-mcp/auth.toml`.

API: `parse(text) → object`.

Альтернатива `@iarna/toml` отвергнута — у smol-toml нет depend tree.
```

`.wiki/packages/zod.md`:
```markdown
---
title: zod
type: package
tags: [validation]
updated: 2026-04-29
---

# zod

Runtime-валидация. Используется в:
- [src/lib/config.ts](../../src/lib/config.ts) — схема `auth.toml`
- [src/tools/tasks.ts](../../src/tools/tasks.ts) — input-схемы tasks-тулов
- [src/tools/knowledge.ts](../../src/tools/knowledge.ts) — input-схемы knowledge-тулов

JSON Schema, который видит MCP-клиент, прописан вручную (см. `inputSchema` каждого tool). zod — отдельный санитайзинг внутри handler'а, чтобы поймать малформед-аргументы.
```

- [ ] **Step 9: Append to .wiki/log.md**

```markdown

## [2026-04-29] init | Реализация sync-script + MCP-сервера

- Добавлены entity-страницы: sync-script, mcp-server, domain-detector.
- Добавлены package-страницы: @modelcontextprotocol/sdk, gray-matter, smol-toml, zod.
- index.md обновлён: сущности и пакеты больше не пустые.
- README.md теперь содержит bootstrap-инструкцию + tools-таблицу.
- Тесты зелёные, build чистый.
```

- [ ] **Step 10: Commit**

```bash
git add README.md .tasks/STATUS.md .tasks/bootstrap-implementation.md .wiki/index.md .wiki/log.md .wiki/entities .wiki/packages
git commit -m "docs: README bootstrap guide + wiki entity/package pages + task closeout"
```

---

### Task 4.3: Push to Gitea

- [ ] **Step 1: Push main**

```bash
git push origin main
```

Expected: Multiple commits pushed cleanly. Verify on Gitea UI: [git.kzntsv.site/OpeItcLoc03/projects-meta-mcp](https://git.kzntsv.site/OpeItcLoc03/projects-meta-mcp).

- [ ] **Step 2: No further commits in this plan.**

---

## Verification checklist (post-plan)

After all tasks done:

- [ ] `npm test` exits 0, all suites pass
- [ ] `npm run build` produces `dist/sync.js` and `dist/server.js` without errors
- [ ] `npm run typecheck` clean
- [ ] `node dist/sync.js` without auth.toml → exit 2 with helpful message
- [ ] `node dist/server.js` starts on stdio without crashing
- [ ] `git log --oneline` shows linear history of feat/chore/docs commits
- [ ] `git push origin main` succeeded
- [ ] [.tasks/STATUS.md](../../.tasks/STATUS.md) lists task as 🟢 done
- [ ] [.wiki/index.md](../../.wiki/index.md) lists 3 entities + 4 packages

End state: pre-merge ready. To exercise live: write `~/.config/projects-mcp/auth.toml`, run `node dist/sync.js`, register MCP in Claude Code, call `meta.status` from a chat session.
