SkillForge

Name: SkillForge MCP Server
Author: tripleyak

Phase-based skill router + creator — triages each request, analyzes via 11 thinking lenses, generates XML specs, and runs multi-agent approval before shipping.

SkillForge is a meta-skill for Claude Code and Codex that decides whether to USE an existing skill, IMPROVE one, CREATE new, or COMPOSE from multiple. It runs 4 phases: triage → deep 11-lens analysis → XML spec → generation with multi-agent synthesis. v5.0 streamlined the SKILL.md to 313 lines with lazy-loaded references so the context stays lean.

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": {
    "skillforge-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/tripleyak/SkillForge",
        "~/.claude/skills/SkillForge"
      ],
      "_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": {
    "skillforge-skill": {
      "command": "git",
      "args": [
        "clone",

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

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

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

~/.continue/config.json

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

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

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

claude mcp add skillforge-skill -- git clone https://github.com/tripleyak/SkillForge ~/.claude/skills/SkillForge

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： SkillForge

Find the right existing skill instead of reinventing one

👤 Anyone with a big skill library and no memory of what's installed ⏱ ~5 min beginner

使うタイミング： You have a task and aren't sure if something already covers it.

フロー

Describe the task

Use skillforge. I need to turn our docs site into a searchable knowledge base.✓ コピーしました

→ Triage returns USE_EXISTING with a recommendation (e.g. skill-seekers)
Confirm and hand off

Good — run that skill.✓ コピーしました

→ Routes to the recommended skill

結果： You use what's already there rather than writing a new skill.

注意点

Triage is over-eager to create new — Explicitly ask 'prefer USE_EXISTING unless match score < 70%'

組み合わせ： skill-seekers-skill

Create a new skill with engineered rigor

👤 Skill authors who want quality, not vibes ⏱ ~30 min intermediate

使うタイミング： Triage returned CREATE_NEW and you want the full 4-phase generation.

フロー

Approve triage

skillforge — CREATE_NEW for a skill that drafts ADRs from design discussions.✓ コピーしました

→ Phase 1 analysis begins with 11 lenses
Review the spec

Show me the XML spec before generation.✓ コピーしました

→ Structured spec you can critique
Run synthesis

Generate, then run the multi-agent panel.✓ コピーしました

→ Panel verdict with unanimous approval or concrete objections

結果： A production-quality SKILL.md ready to install.

注意点

Panel stuck in endless loop — Cap iterations — SkillForge supports an iteration limit flag

組み合わせ： skill-seekers-skill

組み合わせ

他のMCPと組み合わせて10倍の力を

skillforge-skill + skill-seekers-skill

Use SkillForge to decide, then Skill Seekers to actually ingest sources for CREATE_NEW

skillforge triage, then if CREATE_NEW, use skill-seekers to pull in the docs.✓ コピーしました

skillforge-skill + filesystem

Skill output goes straight into ~/.claude/skills/

Write the generated SKILL.md and references to ~/.claude/skills/<name>/.✓ 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
Phase 0 triage	task description + skill library	Start of every request
Phase 1 deep analysis (11 lenses)	task	After triage, before generation
Phase 2-3 XML spec + generation	analysis	CREATE_NEW or IMPROVE_EXISTING
Phase 4 multi-agent synthesis	draft	Final quality gate

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: Full 4-phase generation is token-heavy (10-30k)
金額: Free — skill is local
ヒント: Use triage-only for simple routing; invoke full pipeline only for real skill authoring.

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 — skill is prompts

データ送信先： None from the skill itself

トラブルシューティング

よくあるエラーと対処法

Triage picks wrong verdict

Provide the current skill library list so triage can match properly.

Multi-agent panel keeps rejecting

Check the objections — often a missing section in the spec. Fix once, re-run.

Generated skill feels generic

Give more source material in Phase 1; skill quality follows source quality.

代替案

SkillForge 他との比較

代替案	代わりに使う場面	トレードオフ
skill-seekers-skill	You want document-ingest-first rather than analysis-first	Seekers is heavier on source processing; SkillForge is heavier on engineering rigor
Manual SKILL.md authoring	The skill is small and you have a clear spec	Fastest for trivial skills
