Wählen Sie Ihren Client

~/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
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

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

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

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

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

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

In context_servers hinzufügen. Zed lädt beim Speichern neu.

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

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: skills

Refactor a legacy module using the Clean Code + Refactoring patterns

👤 Senior developers tackling legacy code ⏱ ~120 min advanced

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

Ablauf

Assess with Clean Code lens

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

→ 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.✓ Kopiert

→ Named Fowler refactorings with stepwise plan
Execute incrementally

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

→ Small safe steps, not one giant rewrite

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

Fallstricke

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

Kombinieren mit: claude-skill-2

Run Mom Test-style customer interviews

👤 Founders validating a product idea ⏱ ~45 min intermediate

Wann einsetzen: Before writing any code, you need to pressure-test the problem.

Ablauf

Plan the interview

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

→ 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?✓ Kopiert

→ Honest separation of validated evidence from polite agreement

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

Fallstricke

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

Kombinieren mit: product-manager-skill

Design a system using DDIA + System Design skills

👤 Senior engineers and architects ⏱ ~90 min advanced

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

Ablauf

State constraints

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

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

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

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

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

Fallstricke

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

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

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.✓ Kopiert

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.✓ Kopiert

Kosten & Limits

Was der Betrieb kostet

API-Kontingent: None
Tokens pro Aufruf: 2-6k per skill
Kosten in €: Free — skill is local

Sicherheit

Rechte, Secrets, Reichweite

Credential-Speicherung: No credentials — skill is prompts

Datenabfluss: None

Fehlerbehebung

Häufige Fehler und Lösungen

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.

Alternativen

skills vs. andere

Alternative	Wann stattdessen	Kompromiss
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
