Design or edit a screen or Wear widget in the Compose UI Builder over MCP. Use only for a UI Builder URL (…/ui-builder/…), a .uid design file, or an explicit request to design or author a screen or Wear widget in the UI Builder, explore design alternatives, or turn an approved builder design into Compose code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Compose UI Builder The UI builder is an authoring surface served by `compose-preview serve`: a design is a **document of catalog components**, edited by an operation log, and exported as Compose Kotlin (or PNG/SVG). A person edits it in the browser at `/ui-builder/<catalog>/<designId>`; you edit the same live document over the server's MCP endpoint. Both land in one revision log, so you and a designer can work on the same design at the same time. A design can also live in a checked-in `.uid` file. For a repository design, inspect its schema and follow [the local design-to-code workflow](references/local-design-to-code.md): edit the canonical file, compare real design renders with references, adapt exported Kotlin into the application, then render the affected `@Preview`s. Use `compose-preview` alongside this skill when a composable already exists. The server ships from [compose-preview-server](https://github.com/yschimke/compose-preview-server); people start at <https://ui.coo.ee/start> (longer guide: [`docs/UI_BUILDER_GETTING_STARTED.md`](https://github.com/yschimke/compose-preview-server/blob/main/docs/UI_BUILDER_GETTING_STARTED.md)). …

How to install
mdr add yschimke/skills/compose-ui-builder@sha256:937ba07c123e082cThe line at the top of this page pins the label git:20261101.c6e32f6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
