Handoff Skill

PM-実装役間のハンドオフとワークフロー遷移を管理するスキル。

機能詳細

Quick Reference

• “Cursor に完了報告を書いて” → /handoff cursor
• “OpenCode にハンドオフ” → /handoff opencode
• “レビュー指摘を自動修正” → /handoff auto-fix
• “変更内容とテスト結果を含めて” → Includes git diff and test results

Prerequisites

This command should only run after harness-review APPROVE

Why handoff requires review approval:

• PM receives unreviewed changes otherwise
• Quality not assured
• Breaks /work flow (implement → review → fix → OK → handoff)

Usage

/handoff cursor     # Handoff to Cursor
/handoff opencode   # Handoff to OpenCode

Execution Flow

Step 1: Identify Completed Tasks

• Check Plans.md checkboxes
• Summarize work done

Step 2: Update Plans.md

# Before
- [ ] Task name `pm:依頼中`

# After
- [x] Task name `cc:完了` (YYYY-MM-DD)

Step 3: Gather Changes

git status -sb
git diff --stat

Step 4: Check CI/CD (if applicable)

gh run list --limit 3

Step 4.5: Unified Memory Finalize（必須）

完了報告の前に、共通メモリへ最終状態を確定する:

harness_mem_record_checkpoint(session_id, title, content, tags?, privacy_tags?)
harness_mem_finalize_session(session_id, summary_mode="standard")

これにより Claude Code / Codex / OpenCode のどこからでも同一セッションを再開できる。 session_id は $CLAUDE_SESSION_ID → .claude/state/session.json の .session_id の順で取得する。 harness_mem_sessions_list(project, limit=1) の先頭利用は read-only（resume確認）に限定し、handoff時の record_checkpoint / finalize_session では明示 session_id が無い場合に失敗扱いとする。 harness_mem_finalize_session が失敗している場合は handoff を確定しない。

Step 5: Generate Report

Output Format

## Completion Report

### Summary
- (1-3 lines describing what was done)

### Completed Tasks
- **Task Name**: [Task description]

### Changed Files
| File | Changes |
|------|---------|
| `path/to/file1` | [Summary] |
| `path/to/file2` | [Summary] |

### Verification Results
- [x] Build success
- [x] Tests passed
- [x] Manual verification complete

### Risks / Notes
- (If any)

### Next Actions (for PM)
1. [ ] [What PM should do next]
2. [ ] [Optional items]

/work Integration Flow

/work execution
    ↓
Phase 1: Parallel implementation
    ↓
Phase 2: harness-review loop
    ├── NG (Critical/High) → Fix → Re-review
    └── OK (APPROVE) → Phase 3
    ↓
Phase 3: Auto-commit (if configured)
    ↓
Phase 4: This skill runs ← First time handoff happens

/work automatically calls this skill in Phase 4. When running manually, always do so after harness-review APPROVE.

Target-Specific Notes

Handoff to Cursor

• Plans.md markers use cc:完了 (Japanese)
• Report format optimized for Cursor PM workflow
• Includes context for /review-cc-work command

Handoff to OpenCode

• Similar format to Cursor
• Compatible with OpenCode’s command structure
• Works with multi-LLM development workflow
