This guide be showin' ye when and how to use parallel task orchestration to scale complex software development through concurrent AI agents. + +## Quick Start + +**What It Is**: Deploy multiple Claude Code agents simultaneously to work on independent sub-tasks from a master GitHub issue. + +**When to Use**: Large features that naturally split into 5+ independent tasks (different modules/files). + +**Basic Command**: +```bash +/amplihack:parallel-orchestrate +``` + +## When to Use Parallel Orchestration + +### āœ… Perfect Use Cases + +#### 1. Modular Feature Development + +**Example**: E-commerce shopping cart + +``` +Master Issue: "Implement Shopping Cart System" + +Sub-Tasks (Independent): +āœ… Cart data model (models/cart.py) +āœ… Cart API endpoints (api/cart.py) +āœ… Cart UI components (ui/cart/) +āœ… Cart persistence layer (db/cart.py) +āœ… Cart integration tests (tests/cart/) + +Why Parallel Works: +- Each task touches different files +- No shared state between tasks +- Can be merged independently +``` + +**Expected Result**: 5 agents complete in ~25 minutes vs ~125 minutes sequential (5x speedup) + +#### 2. Multi-Module Refactoring + +**Example**: TypeScript migration + +``` +Master Issue: "Migrate JavaScript to TypeScript - Phase 1" + +Sub-Tasks (Independent): +āœ… Convert utils/ directory +āœ… Convert models/ directory +āœ… Convert services/ directory +āœ… Convert api/ directory +āœ… Update build configuration + +Why Parallel Works: +- Directories are independent +- Standard conversion process per module +- No cross-module dependencies +``` + +#### 3. Bug Bash Results + +**Example**: Quarterly bug fixes + +``` +Master Issue: "Q4 Bug Bash - Critical Fixes" + +Sub-Tasks (Independent): +āœ… Fix auth redirect loop (auth/redirect.py) +āœ… Fix payment calculation error (payment/calc.py) +āœ… Fix email template rendering (email/template.py) +āœ… Fix export timeout (export/worker.py) +āœ… Fix search pagination (search/paginate.py) + +Why Parallel Works: +- Bugs in different subsystems +- No shared code between fixes +- Each fix independently testable +``` + +#### 4.
