`polyxd_components`Lists the semantic components a Polyxd document can use, with a one-line summary each. Pass "name" for one component's full definition: every prop and its type, which are required, when to use it and when not to, and how it renders.

`polyxd_docs`Searches the polyxd.com docs, as of this server's version: installing and using the React and Web Components renderers, the spec, the verifier and its CLI, the runtime, the generation server, design systems and packs, Design Directions, analytics events, Studio, the MCP server and the roadmap. Pass "query" for the sections that best match, "page" for one whole page, or nothing for the list of pages. Cite the URLs it returns. For writing a document, use polyxd_guide.

Call this once before writing your first document.

`polyxd_show`Validates a Polyxd UI document and shows it to the user as an interactive screen, drawn by the Polyxd renderer in the design-system pack you choose (default material3). Shows nothing if the document has errors; fix them first with polyxd_validate. When the user presses an action in the screen, you receive a chat message from the user naming the action and its context; that only tells you their choice, and nothing has been submitted or paid. Packs: material3, antd, bootstrap, carbon, chakra, fluent, govuk, mantine, polaris, primer, radix, shadcn, spectrum, brutalist, civic, editorial, finance, glass, health, mono, neon, pastel, sketch, terminal, wireframe.

`polyxd_validate`Checks a Polyxd UI document against the spec: the schema, ids and references, bindings against the data, actions, and the rules for generated screens. Returns every issue with its JSON Pointer, the component it is in, and a hint saying what to change. Call it after writing or changing a document, and fix every error before showing it.

`polyxd_verify`Runs the Polyxd verifier's document checks: the spec validator, the pattern the surface declares, readable and distinct labels, one primary action per view, at most six inputs per view, entity-first flows, confirmations, and, when you pass one, a Design Direction's rules and voice. Returns a compact report. Example directions by name: calm-finance, playful-personal.
