skill-fetch

作者 girofu · girofu/skill-fetch

Search 9 skill registries at once, score results, and install the winner — a package manager-ish UX for Claude Code skills.

skill-fetch is a meta-skill: it queries multiple community registries for agent skills, ranks matches by relevance and quality signals (stars, recency), and handles the git-clone install step. Saves you from manually browsing nine different 'awesome-claude-skills' lists.

~/Library/Application Support/Claude/claude_desktop_config.json  · Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "skill-fetch-skill": {
      "command": "git",

        "clone",

        "~/.claude/skills/skill-fetch"
      ],
      "_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": {
    "skill-fetch-skill": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/skill-fetch"
      ],
      "_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。

  "mcpServers": {
    "skill-fetch-skill": {
      "command": "git",
      "args": [
        "clone",

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

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

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

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

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

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

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： 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

使うタイミング： You're about to do X and you suspect someone already built a skill for it.

前提条件
  • skill-fetch installed — git clone https://github.com/girofu/skill-fetch ~/.claude/skills/skill-fetch
フロー
  1. Describe what you need
    Use skill-fetch. I need a skill for generating OpenAPI specs from existing code. Search and score the top 5.✓ コピーしました
    → Ranked list with repo, stars, last commit, one-line summary per result
  2. Inspect the top pick
    Show me the SKILL.md of the top result without installing.✓ コピーしました
    → Raw SKILL.md content for review
  3. Install
    Install it.✓ コピーしました
    → git clone output; skill now in ~/.claude/skills/

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

注意点
  • 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

使うタイミング： You installed a bunch of skills months ago and don't remember what they do.

フロー
  1. List installed skills
    Use skill-fetch to list all skills under ~/.claude/skills/ with their current version and last-updated date.✓ コピーしました
    → Table of installed skills
  2. Flag abandoned ones
    Which of these haven't been updated upstream in 6+ months?✓ コピーしました
    → List of stale skills

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

組み合わせ： filesystem

よくあるエラーと対処法

Search returns 0 results for a common query

Hitting rate limits. Set GITHUB_TOKEN env var.

確認： curl -H "Authorization: Bearer $GITHUB_TOKEN" https://api.github.com/rate_limit
Install fails with 'permission denied'

Check ~/.claude/skills/ is writable.

確認： ls -la ~/.claude/skills/
Installed skill doesn't activate

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

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

代替案

skill-fetch 他との比較

代替案代わりに使う場面トレードオフ
Manually browsing awesome-claude-skills listsYou only install a skill once in a blue moonSlow, no scoring, no install automation
claude-skills-vault-skillYou want a curated bundle rather than search-and-pickOpinionated; less flexible
