Start Project

멀티 에이전트 협업으로 프로젝트를 시작한다.

Overview

이 스킬은 3개의 에이전트(Claude, Codex, Gemini)를 협조시켜 프로젝트 개시부터 구현후 리뷰까지를 커버한다.

Workflow

Phase 1: Research (Gemini via Subagent)
    ↓
Phase 2: Requirements & Planning (Claude)
    ↓
Phase 3: Design Review (Codex via Subagent)
    ↓
Phase 4: Task Creation (Claude)
    ↓
Phase 5: CLAUDE.md Update (Claude)
    ↓
[Implementation...]
    ↓
Phase 6: Multi-Session Review (New Session + Codex)

Phase 1: Gemini Research (Background)

Task tool에서 하위 에이전트를 시작하고 Gemini에서 리포지토리 분석한다.

Task tool parameters:
- subagent_type: "general-purpose"
- run_in_background: true
- prompt: |
    Research for: {feature}

    1. Call Gemini CLI:
       gemini -p "Analyze this repository for: {feature}

       Provide:
       1. Repository structure and architecture
       2. Relevant existing code and patterns
       3. Library recommendations
       4. Technical considerations
       " --include-directories . 2>/dev/null

    2. Save full output to: .claude/docs/research/{feature}.md

    3. Return CONCISE summary (5-7 bullet points)

Phase 2: Requirements Gathering (Claude)

사용자에게 질문하여 요구 사항을 명확히 한다.

Ask in Korean:

1. 목적: 무엇을 달성하고 싶습니까?
2. 스코프: 포함하거나 제외하는 것은?
3. 기술적 요건: 특정 라이브러리, 제약은?
4. 성공기준: 완료의 판단기준은?

Draft implementation plan based on Gemini research + user answers.

Phase 3: Codex Design Review (Background)

Task tool에서 하위 에이전트를 시작하고 Codex에서 계획 검토한다.

Task tool parameters:
- subagent_type: "general-purpose"
- run_in_background: true
- prompt: |
    Review plan for: {feature}

    Draft plan: {plan from Phase 2}

    1. Call Codex CLI:
       codex exec --model gpt-5.2-codex --sandbox read-only --full-auto "
       Review this implementation plan:
       {plan}

       Analyze:
       1. Approach assessment
       2. Risk analysis
       3. Implementation order
       4. Improvements
       " 2>/dev/null

    2. Return CONCISE summary:
       - Top 3-5 recommendations
       - Key risks
       - Suggested order

Phase 4: Task Creation (Claude)

서브에이전트 요약을 통합하고 작업 목록을 작성한다.

Use TodoWrite to create tasks:

{
    "content": "Implement {specific feature}",
    "activeForm": "Implementing {specific feature}",
    "status": "pending"
}

Phase 5: CLAUDE.md Update (IMPORTANT)

프로젝트 관련 정보를 CLAUDE.md에 추가한다.

Add to CLAUDE.md:

---

## Current Project: {feature}

### Context
- Goal: {1-2 sentences}
- Key files: {list}
- Dependencies: {list}

### Decisions
- {Decision 1}: {rationale}
- {Decision 2}: {rationale}

### Notes
- {Important constraints or considerations}

This ensures context persists across sessions.

Phase 6: Multi-Session Review (Post-Implementation)

구현 완료 후 다른 세션에서 리뷰를 실시한다.

Option A: New Claude Session

1. Start new Claude Code session
2. Run: git diff main...HEAD to see all changes
3. Ask Claude to review the implementation

Option B: Codex Review (via Subagent)

Task tool parameters:
- subagent_type: "general-purpose"
- prompt: |
    Review implementation for: {feature}

    1. Run: git diff main...HEAD
    2. Call Codex CLI:
       codex exec --model gpt-5.2-codex --sandbox read-only --full-auto "
       Review this implementation:
       {diff output}

       Check:
       1. Code quality and patterns
       2. Potential bugs
       3. Missing edge cases
       4. Security concerns
       " 2>/dev/null

    3. Return findings and recommendations

Why Multi-Session Review?

• Fresh perspective: New session has no bias from implementation
• Different context: Can focus purely on review, not implementation details
• Codex strength: Deep analysis without context pollution

User Confirmation

Present final plan to user (in Korean):

## 프로젝트 계획 : {feature}

### 조사 결과 (Gemini)
{Key findings - 3-5 bullet points}

### 설계 정책 (Codex 검토)
{Approach with refinements}

### 작업 목록 ({N}개)
{Task list}

### 위험과 주의사항
{From Codex analysis}

### 다음 단계
1. 이 계획으로 진행하시겠습니까?
2. 구현 완료 후 다른 세션에서 검토를 수행한다.

Tips

• All Codex/Gemini work through subagents to preserve main context
• Update CLAUDE.md to persist context across sessions
• Use multi-session review for better quality assurance
• Ctrl+T: Toggle task list visibility
