## Goal
[User's goal]

## Tasks

### [Agent Name]
- [ ] Subtask 1
- [ ] Subtask 2

### [Agent Name]
- [ ] Subtask 1

## Execution Order
1. Parallel: [task group]
2. Sequential: [task group]

## Deliverables
- [file path]: [description]

## Risks / Notes
- [known issues]

Phase 3: Approval

Present the plan to the user and confirm:

• "Shall I proceed with this plan?"
• Incorporate any requested changes

Do NOT proceed to Phase 4 without explicit user approval.

Phase 4: Execution

After approval:

1. Create a task list with TodoWrite
2. Launch agents via the Agent tool (in parallel where possible)
   • Provide each agent with specific file paths, changes, and constraints
   • Frontend and backend share API contracts (Zod schemas) — define schemas first, then parallelize
3. If API schema changes are involved:
   • Define Zod schemas in schemas/*.dto.ts (PascalCase) before implementation
   • Backend implements Hono endpoints matching the schema
   • Frontend consumes via Zodios client
4. If DB schema changes are involved:
   • Use Prisma migration workflow (see .claude/skills/prisma-d1.md)
   • Never modify D1 directly with raw SQL
5. Review each agent's results
6. Launch the qa agent to run type check, lint, build, fix issues, and commit:

   bunx tsc -b --noEmit        # type check
   bunx biome check src/        # lint + format
   bun run build                # build all workspaces
   

Phase 5: Report

After all tasks are complete:

1. Update checkboxes in the plan document
2. Update related spec documents if they exist
3. Report results and remaining issues to the user

Constraints

• Do not guess or speculate — say "unknown" when unsure
• Verify the full blast radius before making changes
• Runtime is Bun — use bun / bunx, never npm / npx / yarn
• Commit messages follow commitlint format: type(scope): description
• Zod schemas go in schemas/*.dto.ts (PascalCase)
• TanStack Router routes use directory-based layout (routes/feature/index.tsx)
• Documentation goes in docs/
• Language: All inter-agent communication (prompts and responses) MUST be in English. When replying to the user, always use Japanese (日本語).
