cook-parallel

Execute these tasks in parallel for maximum efficiency: $ARGUMENTS

Mode: PARALLEL - Multiple subagents working concurrently.

⚠️ Anti-Hallucination Reminder

Before modifying ANY code: Verify assumptions with actual code evidence. Search for usages, read implementations, trace dependencies. If confidence < 90% on any change, investigate first or ask user. See .claude/skills/shared/anti-hallucination-protocol.md for full protocol.

Workflow

1. Task Decomposition

• Analyze tasks for independence
• Group into parallelizable work units
• Identify dependencies between units
• Create dependency graph

2. Parallel Research (if needed)

Launch multiple researcher subagents simultaneously:

Task A research ──┐
Task B research ──┼──► Synthesis
Task C research ──┘

3. Parallel Planning

• Use planner subagent with synthesized research
• Create plan with parallel-safe phases
• Mark file ownership boundaries (prevent conflicts)

4. Parallel Implementation

Launch multiple fullstack-developer subagents:

Phase 1 (Backend API) ──┐
Phase 2 (Frontend UI) ──┼──► Integration
Phase 3 (Tests)       ──┘

Critical: Each subagent must stay within file ownership boundaries.

5. Integration & Testing

• Merge parallel outputs
• Use tester subagent for integration tests
• Use debugger if integration issues found

6. Review & Report

• Use code-reviewer for final review
• Consolidate all changes
• Report to user

Parallelization Rules

Rule	Description
File Ownership	Each subagent owns specific files - no overlap
Dependency Order	Respect dependency graph
Max Concurrent	3 subagents max to prevent conflicts
Sync Points	Integration checkpoints between phases

When to Use

• Multi-component features (backend + frontend)
• Large refactoring across independent modules
• Parallel test writing
• Documentation updates alongside code

Example Task Split

"Add user authentication with login UI"
├── Backend API (subagent 1)
│   ├── auth-controller.ts
│   └── auth-service.ts
├── Frontend UI (subagent 2)
│   ├── login-page.component.ts
│   └── login-form.component.ts
└── Tests (subagent 3)
    ├── auth.spec.ts
    └── login.e2e.ts

Trade-offs

Aspect	Parallel	Sequential
Speed	~2-3x faster	Baseline
Coordination	Higher complexity	Simple
Conflicts	Risk of merge issues	None
Context	Split across agents	Unified

IMPORTANT Task Planning Notes

• Always plan and break many small todo tasks
• Always add a final review todo task to review the works done at the end to find any fix or enhancement needed
