설치

클라이언트 선택

~/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 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

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 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

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

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

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

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

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

context_servers에 추가. 저장 시 Zed가 핫 리로드.

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

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

사용 사례

실전 활용법: mattpocock/skills

Apply Matt's TS patterns to an existing project

👤 TypeScript devs upgrading code quality ⏱ ~90 min intermediate

언제 쓸까: Your project has anys and shrug-worthy types and you want a principled cleanup.

사전 조건

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

흐름

Scan

Use mattpocock/ts-review. Scan /src and list every any, every unsafe cast, every type hole. Group by file.✓ 복사됨

→ 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.✓ 복사됨

→ Minimal diffs, type-safety gained
Check

Run tsc --noEmit. Any regressions?✓ 복사됨

→ Clean compile or precisely-scoped remaining items

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

함정

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"

함께 쓰기: filesystem

Build a feature test-first, Matt's way

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

언제 쓸까: You have a new feature to build and want to try test-first with modern TS tooling.

흐름

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.✓ 복사됨

→ Failing test with realistic fixtures
Implement

Now the minimal implementation. Type-safe, no any.✓ 복사됨

→ Green test with clean types
Refactor

Apply refactor patterns from the skill — extract helpers if they earn it, no premature abstraction.✓ 복사됨

→ Refactor only where the skill's criteria are met

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

함정

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

함께 쓰기: filesystem

조합

다른 MCP와 조합해 10배 효율

mattpocock-skills-skill + filesystem

Apply to a full repo

Run ts_review over the whole /src tree and report.✓ 복사됨

mattpocock-skills-skill + github

Open a PR per review

For the top 3 cleanups, create one PR each with a clear description.✓ 복사됨

도구

refactor_with_types	path, goal	Type-preserving refactor

비용 및 제한

운영 비용

API 쿼터: N/A
호출당 토큰: Review-heavy — budget for big reads on large codebases
금액: Free
팁: Scope by directory first; don't scan everything

보안

권한, 시크릿, 파급범위

최소 스코프: filesystem-read

자격 증명 저장: None

데이터 외부 송신: None

문제 해결

자주 발생하는 오류와 해결

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

대안

mattpocock/skills 다른 것과 비교

대안	언제 쓰나	단점/장점
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
