Review form validation so users, including people using screen readers, can understand and correct errors. Check field descriptions, required states, and grouped choices in rendered HTML, while accounting for React forms that handle submission in the browser.

Use when reviewing templates, rendered HTML, or shared components related to Validate forms accessibly. Validate the final browser-facing markup, not just the source framework abstraction. Distinguish between browser-posted forms and client-handled React forms so you do not over-report missing `method` or `action` as accessibility defects.

Inaccessible form validation leaves screen reader users unable to understand what went wrong and how to fix it, causing frustration and form abandonment.
required or aria-requiredVerify forms have client-side validation with accessible error messages linked to form fields via aria-describedby. Do not flag React forms just because they omit method or action when onSubmit clearly handles submission client-side. Confirm required fields are exposed programmatically and grouped controls use fieldset and legend.
Implement validation with clear error messages, aria-invalid states, and aria-describedby references to error text. For client-handled forms, improve validation semantics without forcing server-post patterns that the component is not using. Add required or aria-required where appropriate and use <fieldset> with <legend> for grouped choices.
Explain how accessible form validation improves user experience and ensures all users can understand and correct errors.
Review templates, server-rendered HTML, and shared components that output markup related to Validate forms accessibly. Flag exact elements, attributes, and routes where the rendered HTML violates the rule. Check that help text and error text are both included in aria-describedby and that required state is exposed in markup, not only in visual styling.

Create and review custom 404 pages that help visitors recover from broken or moved links through search and navigation. Check the rendered page and HTTP response so missing content returns a proper 404 status.
