インストール

クライアントを選択

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "mattpocock-skills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/mattpocock/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "mattpocock-skills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/mattpocock/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "mattpocock-skills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/mattpocock/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mattpocock-skills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/mattpocock/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "mattpocock-skills-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/mattpocock/skills",
        "~/.claude/skills/skills"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json

{
  "context_servers": {
    "mattpocock-skills-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/mattpocock/skills",
          "~/.claude/skills/skills"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

claude mcp add mattpocock-skills-skill -- git clone https://github.com/mattpocock/skills ~/.claude/skills/skills

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： mattpocock/skills

Apply Matt's TS patterns to an existing project

👤 TypeScript devs upgrading code quality ⏱ ~90 min intermediate

使うタイミング： Your project has anys and shrug-worthy types and you want a principled cleanup.

前提条件

Skills installed — git clone https://github.com/mattpocock/skills ~/.claude/skills/mattpocock

フロー

Scan

Use mattpocock/ts-review. Scan /src and list every any, every unsafe cast, every type hole. Group by file.✓ コピーしました

→ Itemized findings, not a summary
Fix with principles

Fix the top 20, narrowest fix per case. Respect Matt's "prefer inference" rule — don't explicit-annotate what TS can infer.✓ コピーしました

→ Minimal diffs, type-safety gained
Check

Run tsc --noEmit. Any regressions?✓ コピーしました

→ Clean compile or precisely-scoped remaining items

結果： A measurably more type-safe codebase following a principled methodology.

注意点

Skill applies Matt's opinions where your team disagrees (e.g. interface vs type) — Override with "skip the interface-vs-type conversion, keep existing style"

組み合わせ： filesystem

Build a feature test-first, Matt's way

👤 Devs adopting a more test-forward workflow ⏱ ~60 min intermediate

使うタイミング： You have a new feature to build and want to try test-first with modern TS tooling.

フロー

Write the test

Use mattpocock/test-first. I want to add a parseInvoice function. Write the test (vitest, integration-over-unit bias) before any impl.✓ コピーしました

→ Failing test with realistic fixtures
Implement

Now the minimal implementation. Type-safe, no any.✓ コピーしました

→ Green test with clean types
Refactor

Apply refactor patterns from the skill — extract helpers if they earn it, no premature abstraction.✓ コピーしました

→ Refactor only where the skill's criteria are met

結果： A test suite that tests behavior, an impl that satisfies it, and restraint on the refactor.

注意点

Opinions collide with team's existing Jest setup — Ask the skill to adapt — it's opinionated but can be reoriented

組み合わせ： filesystem

組み合わせ

他のMCPと組み合わせて10倍の力を

mattpocock-skills-skill + filesystem

Apply to a full repo

Run ts_review over the whole /src tree and report.✓ コピーしました

mattpocock-skills-skill + github

Open a PR per review

For the top 3 cleanups, create one PR each with a clear description.✓ コピーしました

最小スコープ： filesystem-read

認証情報の保管： None

トラブルシューティング

よくあるエラーと対処法

Skill feels too opinionated

That's the point — override specific opinions in your prompt, or fork and edit

Recommendations conflict with team style

Share the output with the team; use it as a discussion starter, not a mandate

Doesn't know my niche library

Skills are TS-general — prepend your library's docs to the context

代替案

mattpocock/skills 他との比較

代替案	代わりに使う場面	トレードオフ
Your team's linter config	You need CI-level enforcement, not interactive review	No LLM reasoning, no refactor help
Biome / ESLint with typescript-eslint	Want rules-based, deterministic	Doesn't explain its reasoning the way Matt's skills do
