- All features are implemented in Go with zero CGo dependencies (except optional tree-sitter)
- The
yaad/directory contains the knowledge graph subsystem (separate go module) - The
eyrie/directory contains the LLM gateway/router subsystem - The
sight/directory contains the static analysis subsystem - The
inspect/directory contains the security audit subsystem - The
trace/directory contains the session visualization subsystem - The
tok/directory contains tokenization utilities (secrets, rate limiting, compression) - Features are designed to compose: e.g., the auto-test loop (#3) uses diff-aware test selection (#41) and error pattern learning (#26)
