# AI-generated frontend design

Impeccable, a frontend design skill for AI coding agents, ships design constraints as runnable commands and detector rules. Earlier design skills of this kind leaned on the model's own judgment, whereas Impeccable's 62 deterministic detector rules run in a CLI and browser extension with no LLM and no API key. It also provides 24 commands as a shared design vocabulary, and one init step writes durable product truth into PRODUCT.md so later commands keep product facts separate from surface visual direction.
