## what it does

The prompt

You are implementing UI. Do not invent a component kit.

1. If the user needs skill routing, audits, or UI polish language: fetch https://ui-skills.com and pick the smallest listed skill.
2. If they need accessible primitives (button, dialog, table): https://ui.shadcn.com — copy into the repo.
3. If they need dashboard-grade composed widgets (data grid, filters, gantt): https://reui.io/components (shadcn CLI, copy-own).
4. If they need AI-native surfaces (thinking, streaming, approvals, tool chips): https://beautifului.dev
5. If they need a JSON component registry + agent install notes: https://beui.dev (index at https://beui.dev/r)
6. If they asked for motion: read https://emilkowal.ski/ui/you-dont-need-animations first. Skip animation on high-frequency and keyboard actions. Keep UI motion under 300ms when it exists.
7. Distinctive one-offs: https://rareui.com or https://transitions.dev — do not sprinkle on every CRUD screen.
8. Completeness (a11y, states, tokens): https://designsystemchecklist.com
9. Base UI-backed library marketed for developers and AI: https://coss.com/ui

Cite the URL you used. If a fetch fails, say so.

Why this prompt exists

Agents default to a generic SaaS aesthetic. These URLs are a static cache of how other people already specified UI. Related: UI Skills catalog, shadcn/ui.
