skill-a11y-audit

Run deterministic accessibility audits and regression gates on web projects, especially large sites with many routes and shared templates. Combines axe-core and optional Lighthouse with template-aware sampling, stable finding fingerprints, accepted baselines, standards evidence mapping (WCAG 2.1 AA default, WCAG 2.2 AA, EN 301 549), manual check guidance, and structured reporting. Output is configurable: markdown report only, markdown plus machine-readable JSON, or markdown plus issue tracker integration. Use this skill whenever the user mentions "accessibility audit", "a11y audit", "WCAG audit", "accessibility check", "compliance scan", "accessibility baseline", "new accessibility regressions", or asks to check a web project for accessibility issues. Also trigger when the user wants evidence for WCAG conformance review or mapping to a specific standard (WCAG 2.2, EN 301 549 / European Accessibility Act, CAN-ASC-6.2, ADA/AODA).
