- You’re stuck and need fresh ideas
Handoffs
Section titled “Handoffs”Agents naturally hand off to each other:
Game Designer → Game Architect → Game Scrum Master → Game Developer ↓ ↓ ↓ ↓ GDD Architecture Sprint/Stories Implementation ↓ ↓ Game QA ←──────────────────────────── Game QA ↓ ↓ Test Strategy Automated TestsGame QA integrates at multiple points:
- After Architecture: Define test strategy
- During Implementation: Create automated tests
- Before Release: Performance and certification testing
Project Context
Section titled “Project Context”All agents share the principle:
“Find if this exists, if it does, always treat it as the bible I plan and execute against:
**/project-context.md”
The project-context.md file (if present) serves as the authoritative source for project decisions and constraints.
