cook-parallel Skill | Agent Skills

Execute these tasks in parallel for maximum efficiency: <tasks>$ARGUMENTS</tasks>

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
