/a11y-validate — Accessibility & EAA Compliance Scanner

$ARGUMENTS

Scan a codebase for accessibility issues using pattern-matching heuristics. Detects violations of WCAG 2.1 Level AA, EN 301 549 (the EU harmonized accessibility standard), and the European Accessibility Act (Directive (EU) 2019/882, "EAA", in force since 28 June 2025). Read-only — never modifies files.

Complements /seo-validate (which only covers SEO-a11y overlap shallowly). Use this skill when the concern is legal accessibility compliance, not search engine ranking.

Standards basis:

• WCAG 2.1 Level A + AA — W3C Recommendation 2018 (updated 2023).
• WCAG 2.2 Level AA (opt-in via --standard wcag-2.2-aa) — adds 2.4.11 focus not obscured, 2.5.8 target size minimum, 3.2.6 consistent help, 3.3.7 redundant entry, 3.3.8 accessible authentication.
• EN 301 549 v3.2.1 — EU harmonized standard; aligned with WCAG 2.1 AA plus additional chapters for mobile, hardware, ICT procurement, authoring tools, and functional-performance statements.
• EAA / Directive (EU) 2019/882 — legal framework requiring EN 301 549 conformance for consumer-facing digital products and services in EU markets. Deadline: 28 June 2025. Requires accessibility statements per member-state templates.
