parallel

Parallel Execution Command

Demonstrates the parallel execution pattern from claude-workflow-v2 by launching multiple independent subagents in a single message.

Core Principle

ALL Task calls MUST be in a SINGLE assistant message for true parallelism.

If Task calls are in separate messages, they run sequentially, negating the performance benefit.

Phase 1: Analyze the Request

Parse $ARGUMENTS to determine parallel tasks:

1. Task-based: Multiple independent tasks to execute
2. Directory-based: Multiple directories to analyze
3. Perspective-based: Multiple review angles on same code

If no arguments, demonstrate with a default parallel analysis of the project.

Phase 2: Identify Independent Tasks

For parallelization, tasks must be:

• Independent: No dependencies between them
• Non-conflicting: Don't modify the same files
• Self-contained: Each can complete without the other

Examples of good parallel candidates:

• Code review + Security audit + Test analysis
• Analyze src/ + Analyze lib/ + Analyze tests/
• Check TypeScript + Check ESLint + Check tests

Phase 3: Execute in Parallel

Launch ALL subagents in a SINGLE message using the Task tool:

In ONE message, spawn multiple Task calls:

Task 1: "@code-reviewer Review the authentication module for quality issues"
Task 2: "@security-auditor Check authentication for vulnerabilities"
Task 3: "@test-architect Analyze test coverage for authentication"

Parallelization Patterns

Pattern A: Multi-Perspective Review

Spawn in parallel:
- Logic Reviewer: Focus on correctness and edge cases
- Performance Reviewer: Focus on efficiency and bottlenecks
- Security Reviewer: Focus on vulnerabilities
- Maintainability Reviewer: Focus on code quality

Pattern B: Directory Parallelization

Spawn in parallel:
- Subagent 1: Analyze src/api/
- Subagent 2: Analyze src/models/
- Subagent 3: Analyze src/utils/

Pattern C: Full Verification Suite

Spawn in parallel:
- Type Checker: Run TypeScript/mypy
- Linter: Run ESLint/ruff
- Test Runner: Execute test suite
- Security Scanner: Check for vulnerabilities
