Harness (Meta-skill)

Name: Harness (Meta-skill) (Claude Skill)
Author: revfactory

A meta-skill: tell it your domain, it designs the agent team for you (roles, prompts, hand-offs) and saves the specs for reuse.

Harness treats agent design as a first-class workflow: you describe your domain (incident response, content review, code triage); it asks the right questions, then emits a documented team — roles, system prompts, when each takes over, and shared memory boundaries.

설치

클라이언트 선택

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

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

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

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

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

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

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

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

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

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

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add harness-skill -- git clone https://github.com/revfactory/harness ~/.claude/skills/harness

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

사용 사례

실전 활용법: Harness (Meta-skill)

Design an incident-response agent team

👤 Claude Code users ⏱ ~15 min intermediate

언제 쓸까: You want multiple agents (triage, comms, scribe) cooperating on real incidents instead of one big system prompt.

흐름

Brief

Tell harness: "incident response, B2B SaaS, 3 specialists please."✓ 복사됨

→ Harness asks scope questions
Answer

Define escalation, channels, scribe duties.✓ 복사됨

→ Spec drafts emerge
Save

Save specs into /agents/incident/.✓ 복사됨

→ Reusable team def written

결과: Documented multi-agent team you can rerun next incident, not a one-off prompt.

조합

다른 MCP와 조합해 10배 효율

harness-skill + filesystem

Save designed teams alongside your project

Combine harness-skill with filesystem: Save designed teams alongside your project✓ 복사됨
