aria-allowed-attr

Check whether ARIA attributes, which describe interface elements to assistive technology, are supported by each element’s role. Review rendered HTML and interactive states, identify invalid combinations, and suggest removals or corrections to support accurate screen reader interpretation.

OriginalShow the original description

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Use only allowed ARIA attributes for each role. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Good for

  • Checking ARIA attributes in shared components
  • Reviewing accessibility in a design system
  • Investigating incorrect screen reader output
  • Verifying rendered HTML and interactive states

Overview

What it does

Checks whether the ARIA attributes attached to interface elements are supported by those elements’ roles. ARIA provides information about an element’s meaning and state to assistive technology. Different roles allow different attributes, so the review identifies unsupported combinations and recommends removing or correcting them. It helps make the information a browser passes to assistive technology meaningful and consistent with the element’s role.

When it helps

Use it when reviewing interactive controls, shared components, or a design system. It starts with the meaning built into native HTML elements, then examines the HTML actually rendered and the states that occur during interaction. Where needed, it also checks keyboard operation, focus movement, and the names read aloud by assistive technology, pointing to the specific elements with problems.

Example requests

  • “Check whether this component’s ARIA attributes are allowed for its assigned role.”
  • “Investigate elements whose screen reader output differs from the intended meaning, and suggest attribute corrections and ways to verify them.”

Objective evaluation

AI rated this skill on four points using only the contents of its SKILL.md. Stars and popularity are not taken into account.

Clear instructionsIs it clear when to use it and what it does?
AGoodThe text explicitly describes checking for ARIA attributes unsupported by a role and removing or correcting them.
Concrete stepsAre steps, inputs, outputs, and examples spelled out?
BPartly lackingInspection and correction targets are specified, but role-specific attribute lists and code examples are absent.
SafetyAre sending data, deleting files, and running commands disclosed?
AGoodThe scope is ARIA attribute inspection and correction; external transmission, file deletion, and credential access are not described.
Easy setupDoes it need few tools or API keys, and are they documented?
AGoodBrowser accessibility tools and assistive technology are mentioned, but no mandatory products or API keys are specified.

The total counts each point as A = 25, B = 15, C = 5. Rated by AI (OpenAI Codex) as of Oct 23, 2026. Treat it as a guide and read the original before installing.

Use only allowed ARIA attributes for each role

Invalid ARIA attributes are ignored by screen readers or may cause them to misinterpret the element's purpose, leading to a broken experience for users with disabilities.

Quick Reference

  • Each ARIA role only supports a specific set of ARIA attributes
  • Using unsupported attributes can confuse assistive technologies
  • Ensures the accessibility tree remains valid and meaningful

Check

Verify that all ARIA attributes used on elements are valid for their assigned WAI-ARIA roles.

Fix

Remove or correct ARIA attributes that are not supported by the element's current ARIA role.

Explain

Explain why using only role-supported ARIA attributes is necessary for proper screen reader communication.

Code Review

Review the rendered markup and interactive states that affect Use only allowed ARIA attributes for each role. 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.
