Build accessible, composable UI with @base-ui/react primitives and project styling tokens. Use when creating or refining unstyled primitive components and behavior-heavy UI such as overlays, menus, popovers, dialogs, and form controls, or defining custom component APIs. Prefer the moai-library-shadcn skill when copied-in shadcn components are the primary implementation path.
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
# Base UI Primitives - Skill **Name:** `base-ui` **Purpose:** Build accessible, composable UI with `@base-ui/react` primitives and project styling tokens. Use this when creating or refining unstyled primitive components and behavior-heavy UI. **Applies when:** Building overlays, menus, form controls, or custom component APIs with Base UI. **Do not use when:** You are using copied-in shadcn components as the primary implementation path (use `moai-library-shadcn` first). ## Rules - **Docs first:** Start from [reference-links.md](reference-links.md), then read the exact component page before writing code. - **Behavior before styling:** Preserve Base UI interaction and accessibility behavior before adding project styles. - **Styling agnostic:** Keep logic and visuals decoupled; prefer wrappers and class composition over forking behavior code. - **Tailwind compatibility:** Base UI examples target Tailwind v4. If a target package uses v3, convert unsupported utilities to v3-safe equivalents. - **Composable APIs:** Favor controlled/uncontrolled patterns, small props, and clear slots over monolithic components. …

How to install
mdr add asymmetric-al/core/base-ui@sha256:6e9525578f11f859The line at the top of this page pins the label git:20260923.4bfc185, 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.
