Use when reviewing rendered HTML, interactive components, or design-system patterns related to Ensure ARIA attributes are valid. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Ensure ARIA attributes are valid Invalid ARIA attributes are ignored by browsers and screen readers, potentially leaving users with disabilities unable to navigate or understand the interface. ## Quick Reference - Use only valid, standard-defined ARIA attributes - Avoid misspelled or non-existent aria-* properties - Ensure screen readers correctly interpret element roles and states ## Check Identify any invalid or misspelled ARIA attributes on HTML elements. ## Fix Replace invalid ARIA attributes with their correct names as defined in the WAI-ARIA specification. ## Explain Explain how valid ARIA attributes enable assistive technologies to communicate element state and behavior to users. ## Code Review Review the rendered markup and interactive states that affect Ensure ARIA attributes are valid. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech. --- For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`.

How to install
mdr add thedaviddias/front-end-checklist/aria-valid-attr@sha256:cd57f0a50c3da271The line at the top of this page pins the label git:20260529.7c05904, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
