EPCT: Explore-Plan-Code-Test

Execute systematic development methodology:

Phase 1: EXPLORE

Use explore-codebase to understand relevant parts of the system

Goals:

• Identify where changes need to be made
• Understand existing patterns and conventions
• Map dependencies and impacts
• Locate relevant tests

Deliverable: Exploration summary with affected components

Phase 2: PLAN

Use research-expert to validate approach against best practices

Goals:

• Design solution following project patterns
• Identify edge cases and error handling
• Plan test strategy
• Estimate impact and complexity

Deliverable: Implementation plan with step-by-step approach

Plan Format:

### Implementation Steps
1. [Component A]: [Changes needed]
2. [Component B]: [Changes needed]
3. [Tests]: [Test cases to add]

### Edge Cases
- [Case 1]: [Handling approach]
- [Case 2]: [Handling approach]

### Testing Strategy
- Unit tests: [What to test]
- Integration tests: [Scenarios]
- Manual testing: [Steps]

Phase 3: CODE

Implement the solution:

1. Follow the plan step-by-step
2. Maintain existing code style and patterns
3. Add inline documentation for complex logic
4. Create/update tests alongside code

Phase 4: TEST

Comprehensive validation:

1. Run Linters:

   bun run lint
   eslint .
   prettier --check .
   

2. Run Tests:

   bun test
   pytest
   

3. Manual Testing:

   • Execute test plan scenarios
   • Verify edge cases
   • Check error handling

4. Final Verification:

   Use sniper to ensure 0 linter errors

Deliverable: Tested, validated code ready for commit
