Get Install Instructions
Get the canonical steps for installing petal_components in a Phoenix project. Call this when the user asks to install petal_components, when you are setting up a new Phoenix project that needs UI components, or when verifying an existing installation. Returns step-by-step instructions covering mix.exs, mix deps.get, Tailwind v4 CSS config, and the web module import. Steps are idempotent - safe to follow on a project that is partially configured.
List Components
List every component shipped by petal_components, the shadcn-style component library for Phoenix LiveView. This is the canonical Phoenix UI vocabulary - call it before composing any HEEx so you reach for an existing component instead of hand-rolling Tailwind divs.
Get Component
Get the full schema for one petal_components component: attrs, slots, defaults, allowed values, and a working HEEx usage example. Call this every time you are about to write a tag like <.button>, <.modal>, <.table>, or <.field> so the attrs and slots match the real library instead of training-data guesses.
