Catch WCAG violations before launch
Retrofitting accessibility into a shipped product means re-engineering components, re-testing flows, and often re-designing layouts that were built without considering screen readers, keyboard navigation, or color contrast. Teams that build accessibility checks into their design and development workflow avoid the expensive rework cycle and, more importantly, ship products that more people can actually use.
How the Accessibility Checker works
Feed the agent your designs, prototypes, or live page URLs. It audits against your specified WCAG conformance level (A, AA, or AAA) and reports violations organized by severity and component. The audit covers color contrast ratios for text and interactive elements, presence and quality of alt text for images, heading hierarchy and document structure, ARIA label accuracy and completeness, focus order and keyboard navigability, and touch target sizing for mobile interfaces. Each finding includes the specific WCAG criterion violated, where the violation occurs, and a concrete remediation recommendation.
Why you need the Accessibility Checker
Primary audience:
- Frontend developers who want to catch violations during development rather than receiving accessibility bug reports post-launch
- QA engineers adding accessibility to their testing checklist who need structured audit results they can convert into actionable tickets
- Design system teams responsible for ensuring that shared components meet accessibility standards before they propagate across products
Teams building internal tools with limited public exposure may deprioritize accessibility, but legal and ethical requirements apply regardless of audience size.
How the Accessibility Checker compares
The Accessibility Checker focuses on whether all users, including those using assistive technologies, can perceive, navigate, and interact with the interface. The Responsive Layout Advisor focuses on whether the layout adapts correctly to different screen sizes and orientations. An interface can be fully responsive but completely inaccessible, or fully accessible but broken on mobile. Both agents address quality, but from different angles.
