## 📋 Executive Summary

### Current State
- **Core Engine**: 95% complete, needs polish
- **Plugin System**: 100% complete, needs documentation
- **Dashboard**: 40% complete, needs major overhaul
- **LLM Components**: Built but not integrated (defer to post-MVP)
- **Documentation**: Scattered, needs consolidation

### MVP Goal
A **production-ready optimization tool** that:
- Runs reliable FEA optimizations via manual configuration
- Provides professional dashboard for monitoring and analysis
- Has clear documentation and examples
- Is extensible for future LLM/AtomizerField integration

### Using Claude Code Effectively
```markdown
Best practices for Claude Code assistance:

1. Provide clear context:
   "I'm working on Phase 2.1, migrating dashboard to React TypeScript"

2. Share relevant files:
   - Current implementation
   - Target architecture
   - Specific requirements

3. Ask for complete implementations:
   "Create the complete StudyCard component with TypeScript"

4. Request tests alongside code:
   "Also create unit tests for this component"

5. Get documentation:
   "Write the API documentation for this endpoint"
```

## 📝 Notes

### Development Principles
1. **Stability First**: Make existing features rock-solid before adding new ones
2. **User Experience**: Every feature should make the tool easier to use
3. **Documentation**: Document as you build, not after
4. **Testing**: Write tests before marking anything complete
5. **Modularity**: Keep components loosely coupled for future extensions

### Risk Mitigation
- **Dashboard complexity**: Start with essential features, add advanced later
- **NX compatibility**: Test with multiple NX versions early
- **Performance**: Profile and optimize before issues arise
- **User adoption**: Create video tutorials alongside written docs

### Future Vision (Post-MVP)
- LLM integration for natural language control
- AtomizerField for 1000x speedup
- Cloud deployment with team features
- Plugin marketplace
- SaaS offering
