Build and/or update the MUI in the docs playground or docs experiments
Create a demo page to docs/src/pages/playground/ or docs/src/pages/experiments/ based on the type.
Call out the URL to view the playground or experiment you just created/updated.
For example:
The {{port}} is the dev server port (usually 3000 or 3001) depending on the project.
Very minimal skill that describes the goal (build MUI playground) but lacks actionable steps. Contains only high-level guidance: create a demo page in specific docs paths and output a URL. Missing build commands, prerequisites, file templates, and context. While safe and in a proper skills folder with tags, the content is too sparse to be useful without significant additional knowledge about MUI."
