A11y Audit

Runs axe-core and Lighthouse scans against your web project, maps violations to WCAG 2.1 AA (or other standards like EN 301 549), and outputs structured reports in markdown, JSON, or direct to your issue tracker. The bundled scripts handle dependency resolution automatically, so you don't need accessibility tooling already installed. Includes a discovery mode for large sites that groups pages by template and picks representatives to scan. This is an auditor, not a fixer. It tells you what's broken and points to remediation guidance, but you decide what to fix. Good for compliance checks, CI integration, or kicking off remediation sprints.

Accessibility Audit

Authenticated targets

For explicitly authorized authenticated scans, read references/authenticated-scans.md before execution. Require paired storage state and per-target URL/readiness assertions. Do not infer access approval from possession of a state file. Stop on authentication failure; do not treat a login page as a successful target. Discovery remains unauthenticated. Keep state out of version control and artifacts.

Architecture

This skill operates as a single layer. It reads the project environment, runs automated accessibility tools, maps findings to compliance standards, and produces output in a configurable format. No external skill dependency is required.
