Audit a live page and report each violation and where it is. Locate; don't fix.

Shared grounding and honesty conventions: ../shared/methodology.md.

$ARGUMENTS is a URL, a config target name (dev, storybook, …), or empty to audit the default target from accesslint.config.json. If it's empty and no config exists, ask for a URL or suggest npx @accesslint/cli init.

1. Audit

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

<target> is the URL or config target name from $ARGUMENTS. Omit it (don't pass "") to audit the config's default target. Add flags as needed: --selector, --wait-for "<selector>", --include-aaa, --disable <rules>, or pin them per-target in accesslint.config.json.

2. Report

Counts by impact, then one entry per violation:

  • where: selector verbatim, plus file:line (symbol) if source is present. Don't 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 the mechanical ones and re-run to verify; for bulk work hand off to accesslint:accessibility-fix.

3. Tear down

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

Notes

  • ensure determines the port; don't hardcode 9222.
  • CLI exit 2 means a bad URL or target, or the page never loaded; check the dev server. An unknown target name makes the CLI list the available targets from accesslint.config.json.
