+  Use to independently review UI changes for accessibility and UX-flow

+---
+
+You are an accessibility specialist reviewing changes to a Nuxt 3 / Vue 3
+site (Tailwind, @nuxt/content, @nuxtjs/i18n).
+
+Process:
+1. Determine the changed UI files: `git diff --name-only main...HEAD` filtered
+   to `components/`, `layouts/`, `pages/`, `assets/css/`.
+2. Read each changed file fully and apply the `a11y-review` skill checklist
+   (WCAG 2.1 AA: structure/semantics, keyboard/focus, names/labels/i18n,
+   contrast/motion).
+3. Run `pnpm lint` and report any `vuejs-accessibility/*` violations.
+
+Output a single report grouped by severity:
+- **Blocker** — keyboard trap, missing accessible name, broken landmark,
+  contrast failure.
+- **Should fix** — heading order, redundant landmarks, missing
+  `aria-expanded`.
+- **Nice to have** — minor polish.
+
+Each finding: `file:line`, the problem, and a concrete fix. Be precise and
+brief. Do not modify files unless the caller explicitly instructs you to.

+description: >-
+  Audit Vue/Nuxt components and pages in this repo for accessibility (WCAG 2.1
+  AA) and UX-flow issues. Use whenever adding or changing UI, before opening a
+  PR with visual changes, or when the user asks for an accessibility check.
+---
+
+# Accessibility & UX-Flow Review
+
+Apply this checklist to every changed `.vue` file under `components/`,
+`layouts/`, and `pages/`. Report findings as a short list grouped by
+severity (blocker / should-fix / nice-to-have) with `file:line` refs.
+
+## Structure & semantics
+- One `<h1>` per page; headings increase by one level (no skipped levels).
+- Use semantic elements (`<button>`, `<nav>`, `<main>`, `<header>`,
+  `<footer>`) instead of `div`/`span` with click handlers.
+- Exactly one `<main id="main-content">`; landmark roles are not duplicated
+  with identical `aria-label`s.
+- Interactive `<div>`/`<span>` is forbidden — use a real `<button>`/`<a>`.
+
+## Keyboard & focus
+- Every interactive element is reachable and operable by keyboard.
+- Visible focus style (`focus-visible:ring-*`) on all focusable elements.
+- Disclosure/menu toggles expose `aria-expanded` and `aria-controls`.
+- Overlays/dialogs trap focus, restore focus on close, close on `Escape`.
+- The skip link in `layouts/default.vue` still targets `#main-content`.
+
+## Names, labels, i18n
+- Icon-only controls have an `aria-label` sourced from i18n
+  (`accessibility.*`), never a hard-coded string.
+- All `<img>`/`<NuxtImg>` have meaningful `alt` (empty `alt=""` only for
+  purely decorative images).
+- Form fields have associated `<label>`s.
+- Add new strings to both `i18n/locales/en.json` and `de.json`.
+
+## Visual & motion
+- Text/background contrast meets WCAG AA (4.5:1, or 3:1 for large text);
+  verify against Tailwind tokens in `assets/css/tokens.css`.
+- Animations/transitions respect `prefers-reduced-motion` (covered globally
+  in `tokens.css` — do not reintroduce unconditional long transitions).
+- Tap targets are at least 24x24 px.
+
+## Verification
+- Run `pnpm lint` (eslint-plugin-vuejs-accessibility is wired in).
+- For page-level changes, run `pnpm seo:lighthouse` and keep the
+  `categories:accessibility` gate (error, minScore 0.9) green.

+name: component-scaffold
+description: >-
+  Scaffold a new feature in this Nuxt repo following the house pattern:
+  domain types first, then a composable, then section/UI components, then wire
+  the page. Use when adding any new feature, section, or page.
+---
+
+# Feature Scaffold (types -> composables -> sections -> page)
+
+Follow this order strictly; it is the repo convention from `AGENTS.md`.
+
+1. **Domain types** — add to `types/` (e.g. `types/<feature>.ts`). Model the
+   data the feature renders before touching UI.
+2. **Composable** — add `composables/use<Feature>.ts` that loads/derives the
+   data and exposes a typed, reactive API. Keep data logic out of components.
+3. **Section / UI components** — build under
+   `components/features/<feature>/`, reusing `components/base/*` primitives.
+   Use `<script setup lang="ts">`, 2-space indent, `PascalCase.vue`.
+4. **Page assembly** — the route file in `pages/` only composes sections and
+   calls the composable; it contains no business logic.
+
+## Constraints
+- Do not add new dependencies or config presets without clear justification.
+- Respect the existing directory structure; extend, don't rearrange.
+- Every new string goes into both `i18n/locales/en.json` and `de.json`.
+- Before finishing, run the `a11y-review` skill on the new components and
+  ensure `pnpm lint` and `pnpm build` pass.

+## Reusable Agents & Skills (`.claude/`)
+These are checked in so every CLI/web session gets the same standards. Treat
+them as rules, not suggestions:
+- **`.claude/skills/component-scaffold`** — MUST be followed when adding any
+  new feature/section/page (types → composables → sections → page).
+- **`.claude/skills/a11y-review`** — MUST be run on every changed
+  `components/`, `layouts/`, or `pages/` file before finishing UI work.
+- **`.claude/agents/accessibility-reviewer`** — delegate an independent
+  accessibility pass to this subagent before opening a PR with visual changes.
+- Accessibility tooling is enforced in CI: `eslint-plugin-vuejs-accessibility`
+  via `pnpm lint`, and the Lighthouse `accessibility` gate
+  (error, minScore 0.9) via `pnpm seo:lighthouse`. Keep both green.
+- When adding new skills/agents, place them under `.claude/` and document
+  them here so they remain the single source of truth.
