インストール

クライアントを選択

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

{
  "mcpServers": {
    "agnix-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/avifenesh/agnix",
        "~/.claude/skills/agnix"
      ],
      "_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": {
    "agnix-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/avifenesh/agnix",
        "~/.claude/skills/agnix"
      ],
      "_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。

VS Code → Cline → MCP Servers → Edit

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

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

~/.continue/config.json

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

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

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

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

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： Agnix (Agent Config Linter)

Enforce skill quality in CI before merging to the team's shared skill repo

👤 Teams maintaining a skill library ⏱ ~15 min intermediate

使うタイミング： You don't want a broken SKILL.md frontmatter to ship and break everyone's agent.

前提条件

Server/skill installed and authenticated — See repo README

フロー

Set up CI

Add agnix check to GitHub Actions on every PR touching .claude/ or skills/.✓ コピーしました

→ Workflow file added
Fix locally

Run agnix fix on the staged files. Show me the diff before committing.✓ コピーしました

→ Autofix diff

結果： No more bad-frontmatter incidents in production.

注意点

Some rules are opinion-shaped (e.g., max description length). Tune in .agnix.toml rather than ignoring globally. — Some rules are opinion-shaped (e.g., max description length). Tune in .agnix.toml rather than ignoring globally.

コストと制限

運用コスト

APIクォータ: See provider docs for rate limits
呼び出しあたりのトークン: Varies by tool
金額: See repo README for pricing details
ヒント: Cache tool results and avoid repeated identical calls.

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： Use environment variables; never commit secrets

データ送信先： Tool calls go to the provider's API as documented

トラブルシューティング

よくあるエラーと対処法

rule too strict

Tune in .agnix.toml — every rule has severity/disable settings.

確認： agnix check --explain <rule-id>

LSP doesn't activate

Make sure the editor extension matches your agnix CLI version.

確認： agnix --version vs extension version
