accesslint/skills

One page, automated tier — run the web accessibility (a11y) rule engine against a live page and locate every violation it can detect mechanically. Pass a URL, a config target name (e.g. `accesslint:accessibility-scan dev`), or nothing to use the default target from `accesslint.config.json`. Ensures a debuggable Chrome, runs the @accesslint/core engine over CDP, and returns a worklist of live-DOM WCAG 2.2 violations, each grounded to its DOM selector and source `file:line`. Locates; doesn't edit. Use it for 'is this page accessible', 'check a11y on this URL', 'find contrast and alt-text issues', or to verify a UI change. For hands-on keyboard and screen-reader checks use `accessibility-inspect`; for a whole site or product use `accessibility-audit`; to diff against uncommitted changes or a branch use `accessibility-diff`.

SKILL.md

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

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:
