Skill UI

Shared vocabulary and principles for designing deep modules with small interfaces, clean seams, and testable, AI-navigable codebases.

This skill performs a full-sweep analysis across code decay, architecture, tech debt, and test quality. It applies fixes directly to the codebase with safety checks. Safe changes are auto-applied, while risky changes require confirmation. Based on twelve classic engineering books, it triggers when users want to fix everything or clean up the whole project in a single command.
