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": {
    "skills-skill-8": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangwb8/skills",
        "~/.claude/skills/skills"
      ],
      "_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": {
    "skills-skill-8": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangwb8/skills",
        "~/.claude/skills/skills"
      ],
      "_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": {
    "skills-skill-8": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangwb8/skills",
        "~/.claude/skills/skills"
      ],
      "_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": {
    "skills-skill-8": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangwb8/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

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

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "skills-skill-8",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangwb8/skills",
        "~/.claude/skills/skills"
      ]
    }
  ]
}

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": {
    "skills-skill-8": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/huangwb8/skills",
          "~/.claude/skills/skills"
        ]
      }
    }
  }
}

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

claude mcp add skills-skill-8 -- git clone https://github.com/huangwb8/skills ~/.claude/skills/skills

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： skills

Author a new Claude skill and test it before publishing

👤 Developers who've built one-shot skills and want them actually reliable ⏱ ~60 min intermediate

使うタイミング： You have a draft SKILL.md and want it audited before sharing.

前提条件

Skill cloned to ~/.claude/skills/ — git clone https://github.com/huangwb8/skills ~/.claude/skills/huangwb8-skills

フロー

Scaffold with init-project

Use init-project to scaffold AGENTS.md and CLAUDE.md for my new skill project.✓ コピーしました

→ Directive files appear with sensible defaults
Polish the prompt with better-prompt

Run better-prompt on my SKILL.md body.✓ コピーしました

→ Clearer, more executable wording
Stress-test

Now auto-test-skill my SKILL.md — find weaknesses.✓ コピーしました

→ Failure modes named (vague triggers, missing examples, ambiguous steps)
Write the README

write-skill-readme for this skill.✓ コピーしました

→ README following convention

結果： A skill that passes its own tests before anyone else sees it.

注意点

auto-test-skill flags everything and you fix nothing — Prioritize Critical + Warning; Suggestion-level is aspirational

組み合わせ： skillcheck-free-skill

Compare two implementation approaches with parallel-vibe

👤 Engineers stuck between two architectures ⏱ ~90 min advanced

使うタイミング： You can't decide between approach A and approach B and want to try both.

フロー

Describe both approaches

parallel-vibe: implement approach A (server-sent events) and approach B (polling) in separate workspaces. Same test suite.✓ コピーしました

→ Two independent workspaces with separate code and test results
Compare

Now compare — which is simpler to maintain and which is faster under load?✓ コピーしました

→ Honest tradeoff analysis grounded in both codebases

結果： A data-backed decision between two architectures.

組み合わせ

他のMCPと組み合わせて10倍の力を

skills-skill-8 + skillcheck-free-skill

Cross-validate: auto-test-skill finds design weaknesses, SkillCheck validates spec compliance

Run auto-test-skill, then SkillCheck, then fix whatever either flags.✓ コピーしました

skills-skill-8 + github

git-pr-review + git-publish-release against real PRs and releases

Use git-pr-review on PR #47 then draft the release notes via git-publish-release.✓ コピーしました

ツール

このMCPが提供する機能

ツール	入力	呼び出すタイミング	コスト
init-project	project intent	First commit in a new project	0
better-prompt	draft prompt/instructions	Before shipping any prompt-heavy artifact	0
auto-test-skill	SKILL.md path	Before publishing a skill	0
parallel-vibe	N approaches + test criteria	When you genuinely can't pick an approach on paper	0 + LLM tokens for each branch
git-commit	diff intent	End of a unit of work	0
git-pr-review	PR number or diff	Reviewing a PR you're assigned	0

コストと制限

運用コスト

APIクォータ: None
呼び出しあたりのトークン: parallel-vibe can be expensive — runs multiple solution attempts
金額: Free — skills are local files
ヒント: Use parallel-vibe sparingly; it multiplies your token spend by N branches.

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： No credentials — pure prompts. git-* skills use your local git config.

データ送信先： None from skills themselves; git-* may push to remotes you configure.

トラブルシューティング

よくあるエラーと対処法

Skill not invoked — Claude uses its own defaults instead of init-project

Name the specific skill ('use init-project to scaffold...').

確認： ls ~/.claude/skills/huangwb8-skills/

SKILL.md frontmatter wrong in a sub-skill

Each sub-skill has its own SKILL.md — inspect the specific folder.

確認： head ~/.claude/skills/huangwb8-skills/init-project/SKILL.md

Wrong trigger keywords — git-commit doesn't activate

Say 'use git-commit' explicitly; 'commit' alone is too generic.

代替案

skills 他との比較

代替案	代わりに使う場面	トレードオフ
skillcheck-free-skill	You want spec validation rather than robustness testing	Narrower scope, higher specificity to the agentskills spec
skills-skill-9 (tenequm)	You want broader product-building skills, not just skill authoring	Less meta — more domain skills
