Evaluate user-facing work against WCAG 2.1 AA. Accessibility is a design constraint, not a polish step (Downe Principle 11).
Audits web accessibility for WCAG 2.1 AA compliance using checklists across perceptible, operable, comprehensible, robust principles, with issues and code fixes.
Audits Figma designs or web pages for WCAG 2.1 AA compliance, checking color contrast, keyboard navigation, touch targets, labels, and screen reader support.

For products handling sensitive user contexts (health, finance, domestic violence, government services), also review trauma-informed design principles in ${CLAUDE_PLUGIN_ROOT}/domains/quality/CLAUDE.md. Source: Hussain (Chayn), built on SAMHSA's 6 Principles (2014).
For information-dense or learning-oriented products, supplement WCAG with the Neurodiversity Design System (neurodiversity.design, Soward). Its 8 principle categories with neurotype-to-UI-element matrix address cognitive accessibility needs that WCAG does not fully cover (e.g., font shapes for dyslexia, number formatting for dyscalculia, animation controls for ADHD).
