## Key Components

### RAG System

Complete implementation of Retrieval-Augmented Generation system that enhances the CAD assistant with intelligent API documentation retrieval.

**Key Benefits:**

* \~40% reduction in token usage per prompt
* \~60% fewer API mistakes and correction cycles
* \~2.5x better token/quality ratio

### AI Evaluation Standards

Evaluation metrics and standards for CAD-AI systems, including benchmark metrics for geometry generation, intent matching, and code quality.

**Benchmark Targets:**

* ≥ 99% kernel success rate
* ≥ 90% parametric robustness
* ≤ 2,000 prompt tokens per turn
