simplify skillA

simplify is agent-read markdown (skill) from maquina-app/rails-claude-code: Simplifies and refines Ruby on Rails code following 37signals patterns and the One Person Framework philosophy, while preserving exact functionality. Focuses on recently modified code unless instructed otherwise. Use this skill when simplifying or refactoring Rails code, reviewing recently written Rails code for 37signals/vanilla-Rails conformance, or when asked to make Rails code more vanilla. Triggers on "simplify this", "refactor to 37signals", "make this more vanilla Rails", removing service.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
