Robert C. Martin package design metrics skill. Computes coupling (Ca/Ce/I), abstractness (Na/Nc/A), and distance from the main sequence (D') per package. Classifies packages into zones: pain, uselessness, warning, clean, ok. Read-only. AST abstractness detection via tree-sitter is the default; a text-tier regex fallback runs when AST extraction fails for a specific file.
