description	Generate production-ready, accessible, token-driven component code for ANY framework — React+Tailwind, Next.js, SwiftUI, Vue, Svelte, Angular, Solid, Web Components/Lit, React Native, Flutter, Jetpack Compose, vanilla CSS, or CSS-in-JS. Use when the user wants working UI code for a component or screen in a specific stack.

Skill: Design Code

Render components into a target framework via the adapter system.

Steps

1. Identify the target framework + styling method from the request (or ask).
2. Read frameworks/adapter-protocol.md (the universal contract: token resolution, component contract, styling, dark mode, motion + output rules).
3. Load the concrete adapter:
   • Full references: frameworks/react-tailwind.md, frameworks/nextjs.md, frameworks/swiftui.md.
   • Concise adapters: frameworks/adapters/{vue,svelte,angular,solid,web-components-lit,react-native,flutter,jetpack-compose,vanilla-css,css-in-js}.md.
   • No file for the target? Generate an adapter on the fly using the protocol's "author a new adapter" checklist.
4. Pull the component spec from components/* and the ARIA pattern from accessibility/aria-patterns.md.
5. Resolve all values to tokens (tokens/*.json); apply aesthetic direction if requested (apply-aesthetic skill).

Output rules (mandatory)

Use tokens (never hardcode) · include a11y on every interactive element · handle all applicable of the 8 states · support dark mode at the semantic layer · mobile-first · honor reduced motion · deliver complete files, no placeholders (workflows/redesign-audit.md → Output Completeness).

Verification (mandatory before declaring done)

Code is the highest-stakes output — self-check every time:

1. No hardcoded values — every color/size/radius/shadow/duration/font traces to a token (CSS var / theme key / asset). Run scripts/lint_hardcodes.py over the output; zero raw hex/px/ms AND zero raw Tailwind palette utilities (bg-gray-500, text-blue-600) — use semantic utilities/tokens (bg-surface, text-primary). Run scripts/validate_theme_refs.py so every var(--…) resolves to a defined theme token (no floating tokens). One allowed exception: 3rd-party theme-config (MUI/Mantine) mapping our tokens INTO their API.
2. All applicable states present — Default, Hover, Focus(-visible ring), Active, Disabled, Loading(+aria-busy), Error, Selected — or justified N/A.
3. Accessibility wired — correct role/ARIA per accessibility/aria-patterns.md, keyboard model, focus management, ≥24px target; verify contrast (scripts/contrast.py) for any new color pair.
4. Dark mode + reduced motion + responsive — semantic tokens swap; motion has a prefers-reduced-motion fallback; layout is mobile-first.
5. Completeness — full files, no // ...; if asked for N, deliver N. If any check fails, fix before returning (run a11y-audit if unsure).
6. Single-theme consistency — consume the project's ONE shared token theme (the root CSS-var layer); never define a per-page palette or new colors. Across multiple pages/screens, the same semantic tokens must drive every surface so the whole product stays visually identical and themeable from one place (CLAUDE.md → Single-Theme Consistency).
7. One shared primitive layer — build ONE reusable component per atom (Button, Input, Modal, Badge via cva/equivalent); never repeat utility-class clusters inline across files or hand-roll a div-as-modal per screen. Overlays reuse the single Modal primitive: focus trap, role="dialog", aria-modal="true", aria-labelledby, Escape, return focus on close, backdrop (WCAG 2.4.3 + 2.1.2). See examples/golden/Button.tsx + examples/golden/Modal.tsx.
8. Font loading — NEVER @import web fonts in CSS (render-blocking). Use a framework loader () or + with ; self-host when possible. Font family comes from a token (), never a literal.
