Project Planning
Exclusive to: planner agent
Instructions
1. Restate Goal
One sentence summary of what we're building.
2. Research
- Search codebase for similar patterns
- Identify affected files
- Note dependencies
3. Break Down
Create 3-5 phases, each independently testable.
Estimation Techniques
T-Shirt Sizing
| Size | Hours | Complexity |
|---|---|---|
| XS | 1-2 | Single file |
| S | 2-4 | Few files |
| M | 4-8 | Multiple files |
| L | 1-2 days | Multiple components |
| XL | 3-5 days | Full feature |
Risk Multipliers
- Database migration: 1.5x
- Auth/security: 1.5x
- Third-party: 2x
Risk Matrix
| Level | Criteria | Mitigation |
|---|---|---|
| 🔴 High | Data loss, security, breaking | Rollback plan, staging |
| 🟡 Medium | Performance, UX regression | Feature flag |
| 🟢 Low | Cosmetic, refactor | Standard testing |

## plan.md Output (REQUIRED)
Always create a consolidated `plan.md` file that contains ALL phases and context:
```markdown
# Plan: [Feature Name]
## Context
[What we're building and why]
## Code Patterns to Follow
[Key patterns from codebase research]
## Phases
