It's a set of LLM agent skills focused on software architecture analysis and review. The repo includes two main skills plus shared resources:

architect-design-review: Reviews an approved design spec before implementation starts. It generates architecture diagrams (Mermaid.js), evaluates against a comprehensive set of principles, and produces a beautiful HTML report.

architect-codebase-review: Analyzes an existing codebase, maps its current architecture (with real evidence from the code), evaluates it, and proposes recommended improvements with revised diagrams.

Both skills output self-contained HTML reports with embedded interactive Mermaid diagrams, saved to docs/architecture/review/. No heavy dependencies—just an internet connection for Mermaid rendering via CDN.
