💡 Recommendations

Immediate Priorities

1. Validate Phase 1 & 2 with real APIs (1 hour)

   • Ensures foundation is solid
   • Documents baseline accuracy
   • Identifies any integration issues

2. Complete Phase 3 (2-3 hours)

   • Adds third LLM option
   • Demonstrates pattern scalability
   • Enables provider comparison

3. Implement Phase 4 (3-4 hours)

   • Dramatically improves accuracy
   • Makes system production-ready
   • Enables complex ROM modifications

Long-Term Improvements

• Caching: Add response caching to reduce API costs
• Rate Limiting: Implement request throttling
• Async API: Non-blocking LLM calls
• Context Windows: Optimize for each provider's limits
• Fine-tuning: Custom models for z3ed commands
