Components.build Specification

This repository (Asymmetric-al/core)

These repo-owned sections are intentionally kept on top of the vendored components.build skill. If upstream refreshes replace this file, reconcile this overlay before running bun run skills:sync.

Base UI only: shared primitives come from @base-ui/react via the shadcn base-maia style in packages/ui. Where the vendored spec references Radix or asChild, use Base UI's render prop instead and never add radix-ui/@radix-ui/*. See docs/ai/rules/frontend.md.

Triggers

Creating, reviewing, or refactoring reusable React components, component APIs, slots, or composition patterns.
Design-system work in packages/ui/, shadcn-compatible primitives, or shared app UI surfaces.
Accessibility, controlled/uncontrolled state, polymorphism, or TypeScript prop contract decisions for components.

Workflow

Read docs/ai/rules/frontend.md and any nested AGENTS.md for the target package/app.
Search existing shared components before adding a new primitive or abstraction.
Prefer repo patterns and shadcn-compatible composition over bespoke APIs.
Keep behavior and accessibility test coverage proportional to the component's reuse surface.
Run focused type/lint/unit checks for touched component packages.

Checklist

Existing components and exports were checked before adding new API surface.
Composition, keyboard, ARIA, focus, and disabled/loading states were considered.
Props/types follow the local package's public export pattern.
Styling uses repo tokens/utilities and avoids layout-shifting dynamic content.
Verification covered the touched component behavior or contract.

Comprehensive guidelines for building modern, composable, and accessible UI components. Contains 16 rule categories covering everything from core principles to distribution, co-authored by Hayden Bleasel and shadcn.
