name: audit-a11y\nversion: 1.1.1\ndescription: |\nPer-route axe-core audit of a pracht app in a headless browser: alt text,\ncontrast, landmarks, focus order, and form labels, grouped by severity and\nroute.\nUse for \"audit a11y\", \"check accessibility\", \"axe my app\", \"WCAG compliance\",\n\"screen reader test\".\nallowed-tools:
\nStatic linting cannot prove a route is accessible — many issues only appear\nin the rendered DOM. This skill renders each route in a real browser and\nruns axe-core against the result.
\nPrefer the production build/runtime — production HTML is what users actually\nreceive. pracht preview builds and serves it for Node and Cloudflare\ntargets. It refuses Vercel targets (it prints guidance and exits nonzero):\nfor a Vercel app, run vercel dev yourself or point BASE_URL at a deployed\npreview instead. Fall back to pracht dev only if the user can't build.
Run the server as a managed background process, wait for readiness, and clean\nit up when the audit ends:
\npracht preview & # run in the background (use the Bash tool's background mode)\n# wait for readiness before auditing:\nuntil curl -sf http://localhost:3000 > /dev/null; do sleep 1; done\nAfter Step 5 (or on any failure), kill the background process — do not leave\na stray server holding the port.
\nOr, if BASE_URL is set, target the deployed app and skip the local server\nentirely.
If Playwright is already wired (see scaffold-e2e), reuse it. Install the\naxe adapter plus tsx (the Step 5 runner — it is not a pracht dependency):
pnpm add -D @axe-core/playwright tsx\nIf Playwright is not wired, scaffold a one-off script using playwright\ndirectly. Prefer Playwright over Puppeteer for consistency with existing\nproject tooling.
MCP: when the pracht MCP server is registered (pracht dev-mcp), prefer its\ninspect_routes/inspect_api/inspect_build/doctor/verify tools over\nshelling out.
pracht inspect routes --json\nPrerequisite: pracht inspect needs a vite config with the pracht plugin\nwired up.
For dynamic-segment routes, ask the user once for example params (or skip\nwith a note in the report).
\nscripts/audit-a11y.ts:
import { chromium } from \"playwright\";\nimport AxeBuilder from \"@axe-core/playwright\";\n\nconst BASE = process.env.BASE_URL ?? \"http://localhost:3000\";\nconst ROUTES: string[] = [/* injected from pracht inspect routes */];\n\nconst browser = await chromium.launch();\nconst context = await browser.newContext();\nconst page = await context.newPage();\n\nconst results = [];\nfor (const path of ROUTES) {\n await page.goto(`${BASE}${path}`, { waitUntil: \"networkidle\" });\n const axe = await new AxeBuilder({ page })\n .withTags([\"wcag2a\", \"wcag2aa\", \"wcag21aa\", \"best-practice\"])\n .analyze();\n results.push({ path, violations: axe.violations });\n}\n\nawait browser.close();\nconsole.log(JSON.stringify(results, null, 2));\npnpm exec tsx scripts/audit-a11y.ts > a11y-report.json\nThen stop the background server from Step 1.
\nAggregate by:
\nReport findings with a primary severity of error / warn / info,\nmapping axe impacts: critical + serious → error, moderate → warn,\nminor → info. Keep the raw axe impact as a secondary column.
## Per-route summary\n\n| Route | Critical | Serious | Moderate | Minor |\n| ----------- | -------- | ------- | -------- | ----- |\n| / | 0 | 1 | 2 | 0 |\n\n## Per-rule summary (top offenders)\n\n- `color-contrast` — 12 violations across 8 routes\n → Likely source: shared Button component (src/components/Button.tsx)\n- `image-alt` — 5 violations across 3 routes\n → Likely source: <img> in shells/marketing.tsx\n\n## Detail\n\n[per-route violations with selectors and help URLs]\nFor the top 3 issues, propose concrete patches:
\ncolor-contrast → suggest tokenized color pairs from existing CSS vars.image-alt → list every <img> missing alt and propose either a\ndescription or alt=\"\" (decorative).landmark-one-main → confirm shells render exactly one <main> element.label → list inputs without associated <label> and propose\nhtmlFor/for or wrapping pattern.<h1>\nafter each navigation. If vite.config.ts sets\nclient: { accessibleNavigation: false }, report that the app must do both\nitself, and check that it does.$ARGUMENTS
