安装

选择你的客户端

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

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

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

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

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

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

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

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

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

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

加入 context_servers。Zed 保存后热重载。

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

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： skill-fetch

Find and install a skill for a task you're doing right now

👤 Claude Code users who don't know what skills exist ⏱ ~5 min beginner

何时使用： You're about to do X and you suspect someone already built a skill for it.

前置条件

skill-fetch installed — git clone https://github.com/girofu/skill-fetch ~/.claude/skills/skill-fetch

步骤

Describe what you need

Use skill-fetch. I need a skill for generating OpenAPI specs from existing code. Search and score the top 5.✓ 已复制

→ Ranked list with repo, stars, last commit, one-line summary per result
Inspect the top pick

Show me the SKILL.md of the top result without installing.✓ 已复制

→ Raw SKILL.md content for review
Install

Install it.✓ 已复制

→ git clone output; skill now in ~/.claude/skills/

结果： A new skill installed, tested, and ready — 5 minutes from 'I need something' to 'I have it'.

注意事项

Installing a skill without reading SKILL.md first — Always inspect the SKILL.md — skills can include hooks that run arbitrary code

Audit the skills you already have installed

👤 Users with a cluttered ~/.claude/skills/ directory ⏱ ~10 min beginner

何时使用： You installed a bunch of skills months ago and don't remember what they do.

步骤

List installed skills

Use skill-fetch to list all skills under ~/.claude/skills/ with their current version and last-updated date.✓ 已复制

→ Table of installed skills
Flag abandoned ones

Which of these haven't been updated upstream in 6+ months?✓ 已复制

→ List of stale skills

结果： Knowledge of what's installed, what's active, and what can be removed.

搭配使用： filesystem

组合

与其他 MCP 搭配，撬动十倍杠杆

skill-fetch-skill + woodshed-skill

Find candidate skills with skill-fetch, then iterate on improvements with woodshed

Find a skill for X, install it, then use woodshed to test and refine it for my use case.✓ 已复制

skill-fetch-skill + filesystem

Batch manage skills directory structure

Archive all skills not used in the last 30 days into ~/.claude/skills-archive/✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用	成本
search_registries	query, limit	Finding skills across multiple sources	9 HTTP requests
inspect_skill	repo URL	Preview before install	1 HTTP request
install_skill	repo URL, local name	After inspection, to add the skill locally	git clone
list_installed	none	Auditing what you have	local read

成本与限制

运行它的成本

API 配额: Subject to GitHub API limits (60/h unauthenticated, 5000/h with PAT)
每次调用 Token 数: ~500 tokens per search result
费用: Free
提示: Set GITHUB_TOKEN to get 5000 req/h instead of 60.

安全

权限、密钥、影响范围

凭据存储： Optional GITHUB_TOKEN for higher rate limits

数据出站： GitHub API and skill registries only

Installing a third-party skill runs its prompts and any included hook scripts. Always inspect SKILL.md and any bin/ or hooks/ directories before install.
Skills can access your local files through Claude Code's filesystem tools — treat unknown skills like unknown npm packages.

故障排查

常见错误与修复

Search returns 0 results for a common query

Hitting rate limits. Set GITHUB_TOKEN env var.

验证： curl -H "Authorization: Bearer $GITHUB_TOKEN" https://api.github.com/rate_limit

Install fails with 'permission denied'

Check ~/.claude/skills/ is writable.

验证： ls -la ~/.claude/skills/

Installed skill doesn't activate

Skills need a valid SKILL.md with YAML frontmatter. Inspect the cloned directory.

验证： head ~/.claude/skills/<name>/SKILL.md

替代方案

skill-fetch 对比其他方案

替代方案	何时用它替代	权衡
Manually browsing awesome-claude-skills lists	You only install a skill once in a blue moon	Slow, no scoring, no install automation
claude-skills-vault-skill	You want a curated bundle rather than search-and-pick	Opinionated; less flexible
