---
## Key Decisions Made
1. **Documentation Structure**
- Decided to create subfolder `docs/design-system/` instead of root-level files
- Numbered files for clear progression (00-99)
- Separate AI guidelines document (08-ai-guidelines.md)
- Quick reference as 99-reference.md (bookmark destination)
2. **Learning Paths**
- Created 6 different learning paths for different user needs
- Speedrun (5 min) → Comprehensive Mastery (1 hour)
- Specialized paths for component development, layouts, forms, AI setup
3. **Content Philosophy**
- Pareto principle: 80% coverage with 20% content
- 5 essential layouts cover 80% of needs
- Decision trees for common questions
- Before/after examples showing anti-patterns
4. **AI Optimization**
- Dedicated 08-ai-guidelines.md with strict rules
- ALWAYS/NEVER sections for clarity
- Component templates for AI code generation
- Integration instructions for Claude Code, Cursor, GitHub Copilot
5. **Link Strategy**
- Internal doc links: Relative paths (`./02-components.md`)
- Demo page links: Absolute routes (`/dev/components`)
- Anchor links for specific sections (`#color-system-oklch`)
- All links verified during review
---
## Next Steps
### Immediate: Begin Phase 2
1. **Create utility components** (`BeforeAfter.tsx`, `CodeSnippet.tsx`, `Example.tsx`)
- Reusable across all demo pages
- Consistent styling
- Copy-paste functionality
2. **Enhance /dev/page.tsx** (hub)
- Landing page for all demos
- Quick navigation
3. **Create demo pages in order**
- `/dev/components/page.tsx` (most referenced)
- `/dev/layouts/page.tsx`
- `/dev/spacing/page.tsx`
- `/dev/forms/page.tsx`
### Future Enhancements (Post-Phase 2)
- Add search functionality to documentation
- Create video tutorials referencing docs
- Add print-friendly CSS for documentation
- Create PDF versions of key guides
- Add contribution guidelines for design system updates
---
## Lessons Learned
1. **Ultrathink Required**
- Initial plan needed refinement after user feedback
- Comprehensive review caught issues early
2. **Time Estimates Removed**
- User preference: No time estimates in section headers
- Focus on content quality over reading speed
3. **Link Verification Critical**
- Agent review caught broken cross-references
- Incomplete imports in examples
- Fixed before Phase 2 begins
4. **Documentation Coherence**
- Cross-referencing between docs creates cohesive system
- Multiple entry points (learning paths) serve different needs
- Quick reference (99-reference.md) serves as bookmark destination
