Author UI Primitives

Use this skill when building or revising packages/ui primitive APIs. The public @remix-run/ui/* entries are sourced from packages/ui/src/* and are not available through the remix package.

Source Layout

Each public primitive has a top-level packages/ui/src/<name>.ts or packages/ui/src/<name>.tsx entry.

Common files:

• <name>.ts or <name>.tsx: the public primitive entry and implementation.
• <name>/README.md: usage docs for the primitive.
• <name>.test.ts or <name>.test.tsx: primitive tests.
• demos/<name>.demo.tsx: demo cases for the shared UI demo app.
• lib/*: shared implementation-only behavior used by multiple primitives.
