## Failed Refactorings

### 1. `store.ts` (2464 lines) ❌
- **Issue**: Sub-agent made changes that broke build (`Cannot read properties of undefined (reading 'mainHand')`)
- **Action**: Reverted changes with `git restore .`
- **Status**: Flagged as "too large for current sub-agent setup"

### 2. `skill-evolution.ts` (2312 lines) ❌
- **Issue**: Larger than `store.ts` which failed
- **Status**: Flagged as "too large for current sub-agent setup"

### 3. `gameStore.ts` (509 lines) ❌
- **Issue**: Sub-agent returned empty result (context limits or other issue)
- **Status**: Will try again with simpler prompt, or flag as "sub-agent unstable for this file"

## Next Files to Refactor

### High Priority (Smaller, Likely to Work)
1. `src/components/game/tabs/DebugTab.tsx` (700 lines) - Split by functional area
2. `src/app/page.tsx` (465 lines) - Lazy load tabs

### Medium Priority
3. `src/components/game/StatsTab.tsx` (551 lines) - Extract sub-components
4. `src/lib/game/stores/index.test.ts` (maybe not needed)

## Build Status
✅ Build passes after each successful refactoring
✅ All commits pushed to remote (`git push origin master` successful)

## Notes
- Sub-agents work best with files under ~1500 lines with focused prompts
- Files over 2000 lines consistently fail (context limits)
- Some files around 500 lines also fail occasionally (unstable sub-agent behavior)
- When in doubt, flag it and move on (per user instructions)
