How to validate UI specifications with your AI

Connect the Accessibility Prover to your AI client. It scans your design specs to catch accessibility gaps before they hit production.

Ask AI about this page

Short answer

Can my AI check my UI designs for accessibility?

Yes. Your AI uses the validate_accessibility tool to compare your component specs against WCAG 2.2 AA requirements. You'll get a breakdown of specific failures to fix.

Where every issue lands.

The results of your scan.

The AI categorizes every finding based on its severity and the type of fix needed.

CRITICAL

Direct violations

The AI flags specific elements that fail WCAG 2.2 AA rules. These are the non-negotiable errors you must fix.

WARNING

Potential failures

The AI identifies specs that might cause issues depending on how they are coded. These require a human to verify.

ADVICE

Best practices

The AI suggests improvements for better usability. These aren't strict violations but help improve the user experience.

HUMAN

Manual review

The AI flags ambiguous specifications where it lacks enough data to make a call. You'll need to inspect these yourself.

The workflow

What your AI does when the spec arrives.

The AI handles the technical comparison so you don't have to manually check every property.

  1. Read specifications

    Your AI client ingests the raw design data or component properties you provide.

    validate_accessibility

  2. Run WCAG checks

    The AI compares your provided data against the WCAG 2.2 AA rule set.

    validate_accessibility

  3. Identify gaps

    The AI isolates specific failures like poor color contrast or insufficient touch targets.

    validate_accessibility

  4. Report findings

    The AI presents a structured list of what passed and what failed the check.

FAQ

How this task behaves.

  • 01

    Does the AI fix my design files?

    No. The AI only identifies the accessibility failures. You have to make the actual changes in your design tool.

  • 02

    Can it scan a live website URL?

    No. This tool validates the specific component specifications you provide in the chat.

  • 03

    What happens if the spec is incomplete?

    The AI will flag the ambiguity as a manual review item, noting that it cannot confirm compliance without more data.

  • 04

    Does it handle WCAG 2.1?

    No. It is specifically built to validate against WCAG 2.2 AA standards.

  • 05

    Can the AI delete my design data?

    No. The AI only reads the data you provide to perform the validation.
