🏗️ Architecture Patterns

MVC-like:

• Models: Data classes, API interfaces
• Views: Terminal output, formatting
• Controllers: Command parsers, handlers

Service Layer:

• Memory service (PostgreSQL + ChromaDB)
• Agent service (Nyx, G1, Kronos)
• Generation service (Images, videos, music)
• Web3 service (Blockchain operations)

Repository Pattern:

• Database interactions abstracted
• Consistent interface for data access

🚀 Performance

Optimizations:

• Async operations (where possible)
• Connection pooling (database)
• Caching (model outputs)
• Batch processing (embeddings)

Scalability:

• Stateless agent calls
• Modular architecture
• Configurable limits
• Resource-aware processing
