Plan

2. Create the Plan (Scaled to Complexity)

Level 2 - Simple Plan

## Implementation Plan

### Files to Modify
- [file]: [what changes]

### Steps
1. [Step with clear deliverable]
2. [Step with clear deliverable]
...

### Success Criteria
- [ ] [Testable criterion]
- [ ] [Testable criterion]

Level 3 - Comprehensive Plan

## Implementation Plan

### Components
1. [Component]: [purpose]
   - Files: [list]
   - Dependencies: [list]

### Implementation Steps
1. [Step]: [details, files, approach]
2. [Step]: [details, files, approach]
...

### Creative Phases Needed
- [ ] [Component requiring design decisions] - Type: [architecture|ui-ux|algorithm]

### Success Criteria
- [ ] [Testable criterion]
- [ ] [Testable criterion]

### Risks & Mitigations
- [Risk]: [mitigation]

Level 4 - Architectural Plan

## Implementation Plan

### Architecture Overview
[High-level description of the system changes]

### Phases
#### Phase 1: [Name]
- Objective: [what this phase accomplishes]
- Components: [list]
- Files: [list]
- Success criteria: [list]
- Estimated scope: [small/medium/large]

#### Phase 2: [Name]
[same structure, noting dependencies on Phase 1]

### Creative Phases Needed
- [ ] [Component] - Type: [architecture|ui-ux|algorithm]

### Cross-Cutting Concerns
- [Concern]: [approach]

### Success Criteria
- [ ] [Testable criterion per phase]

### Risks & Mitigations
- [Risk]: [mitigation]

3. Identify Creative Phases

For Level 3-4, flag components that need design exploration:

• Multiple valid approaches exist
• Architectural decisions with trade-offs
• UI/UX patterns to evaluate
• Algorithm selection needed

Document these as "Creative Phases Needed" in the plan.

4. Update Memory Bank

Update memory-bank/tasks.md:

• Add the complete implementation plan
• Mark planning as complete
• List creative phases if any

Update memory-bank/activeContext.md:

• Current phase: PLAN (complete)
• Next phase: CREATIVE or BUILD
• Key files identified

Output Format

Display the plan, then:

== PLAN COMPLETE ==

Complexity:       Level [N]
Components:       [count]
Creative phases:  [count or "none"]
Next step:        /[creative or build]

Routing

• If creative phases were identified: "Run /creative to explore design decisions."
• If no creative phases: "Run /build to start implementation."
