설치

클라이언트 선택

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

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

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

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

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

VS Code → Cline → MCP Servers → Edit

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

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

~/.codeium/windsurf/mcp_config.json

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

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

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

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

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

context_servers에 추가. 저장 시 Zed가 핫 리로드.

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

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

사용 사례

실전 활용법: skills

Refactor a legacy module using the Clean Code + Refactoring patterns

👤 Senior developers tackling legacy code ⏱ ~120 min advanced

언제 쓸까: You're about to touch a 500-line god-class and want principled guidance.

흐름

Assess with Clean Code lens

Use the Clean Code skill. Review this file — what SOLID violations are present?✓ 복사됨

→ Concrete violations named after principles, not vibes
Plan with Refactoring patterns

Use the Refactoring Patterns skill. Plan the refactor using Extract Class and Replace Conditional with Polymorphism.✓ 복사됨

→ Named Fowler refactorings with stepwise plan
Execute incrementally

Apply the first step; run tests; repeat.✓ 복사됨

→ Small safe steps, not one giant rewrite

결과: A refactor defensible in code review with explicit principles.

함정

Refactor without tests = risk — Skill insists on characterization tests first

함께 쓰기: claude-skill-2

Run Mom Test-style customer interviews

👤 Founders validating a product idea ⏱ ~45 min intermediate

언제 쓸까: Before writing any code, you need to pressure-test the problem.

흐름

Plan the interview

Use the Mom Test skill. I want to validate [idea]. Help me draft questions that avoid bias.✓ 복사됨

→ Questions focused on past behavior, not hypothetical future
Debrief after calls

Here are notes from 5 calls. Apply the Mom Test frame — what's signal vs compliment?✓ 복사됨

→ Honest separation of validated evidence from polite agreement

결과: Interview notes you can actually make a decision on.

함정

Customer says 'I'd buy that' — skill flags this as worthless without behavior evidence — Trust the frame; push for past behavior

함께 쓰기: product-manager-skill

Design a system using DDIA + System Design skills

👤 Senior engineers and architects ⏱ ~90 min advanced

언제 쓸까: You're whiteboarding a new service and want depth, not hand-waving.

흐름

State constraints

Use the DDIA and System Design skills. Design a real-time leaderboard for 5M users. Discuss reliability, scalability, maintainability.✓ 복사됨

→ Tradeoffs from DDIA vocabulary (replication, partitioning, consistency)
Pressure-test

Apply the Release It! skill — what failure modes should I anticipate?✓ 복사됨

→ Stability patterns (circuit breaker, bulkhead, timeout) named explicitly

결과: A design doc that a staff engineer would take seriously.

함정

Skills can over-index on book vocabulary — Insist on concrete numbers — latency targets, QPS, data sizes

조합

다른 MCP와 조합해 10배 효율

skills-skill + product-manager-skill

Books-based discovery + PM deliverable templates

Use Mom Test skill for the interview plan, then the product-manager-skill to turn findings into a PRD.✓ 복사됨

skills-skill + claude-skill-2

Clean Code / Refactoring skill for principles + full-stack skill for implementation

Refactor the auth module guided by the Clean Code skill; implement with the NestJS skill from claude-skill-2.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출
Code Craftsmanship skills (14)	code to review/design	Code quality, architecture, design work
UX Design skills (8)	design problem	UI/UX decisions
Product Strategy skills (4)	product question	Discovery, framing
Marketing & CRO skills (4)	marketing question	Messaging, landing pages
Strategy & Growth skills (4)	strategy question	Market/strategy decisions

비용 및 제한

운영 비용

API 쿼터: None
호출당 토큰: 2-6k per skill
금액: Free — skill is local
팁: Pick one book-skill per task; stacking too many blurs recommendations.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No credentials — skill is prompts

데이터 외부 송신: None

문제 해결

자주 발생하는 오류와 해결

Skill quotes principles but doesn't apply them

Force application: 'apply this principle to THIS line of my code, not in general'.

Not obvious which skill to invoke

The README maps problems to skills — start there.

대안

skills 다른 것과 비교

대안	언제 쓰나	단점/장점
Reading the books directly	You want depth and have time	More depth, no interactive application
product-manager-skill / claude-skill-2	You want deliverable templates or framework code, not book wisdom	Different modality
