Design skill and lint rules that steer AI coding agents toward better UI
What it is
A skill pack for AI coding agents that adds a shared design vocabulary of 24 commands such as audit, critique, polish, typeset, and layout, plus a setup step that records product context in PRODUCT.md. A bundled engine runs 61 deterministic detector rules that flag common AI-generated frontend tells like overused fonts, nested cards, and gray text on color, without needing an LLM or API key. Developers who build interfaces with Claude Code, Cursor, Codex, Gemini CLI, and similar tools install it to get less generic, more deliberate frontend output, with live in-browser variant iteration.
