网页无障碍访问性审计

Audit a live page and report what's broken and where. Locate; don't fix. If no URL in $ARGUMENTS, ask for one.

When to Use

• Use this skill when the task matches this description: Audit a live page for accessibility issues, locate each WCAG violation precisely, and return a selector-grounded fix worklist without editing.

1. Audit

PORT=$(npx -y @accesslint/chrome@latest ensure | node -e 'process.stdin.on("data",d=>process.stdout.write(""+JSON.parse(d).port))')
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --format json

Flags as needed: --selector, --wait-for "<selector>", --include-aaa, --disable <rules>.

2. Report

Counts by impact, then one entry per violation:

• where — selector verbatim + file:line (symbol) if source is present — never fabricate. If no violation has source, note "source mapping unavailable — located by selector only".
• evidence — contrast ratio, missing attribute, empty name
• fix — mechanical change or NEEDS HUMAN

Don't edit. For fixes: apply mechanical ones then re-run to verify; for bulk work hand off to accesslint:audit.

3. Tear down

npx -y @accesslint/chrome@latest stop --all  # skip if ensure reported "managed":false

Gotchas

• ensure always determines the port — never hardcode 9222.
• CLI exit 2 = bad URL or page never loaded; check the dev server.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
