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.
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
# Validate forms accessibly Inaccessible form validation leaves screen reader users unable to understand what went wrong and how to fix it, causing frustration and form abandonment. ## Quick Reference - Associate error messages with fields using aria-describedby - Use aria-invalid to indicate validation state - Mark required fields programmatically with `required` or `aria-required` - Provide inline error messages near the field - Don't rely solely on color to indicate errors - Keep help text and error text linked to the field throughout validation ## Check Verify 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. ## Fix …

How to install
mdr add thedaviddias/front-end-checklist/form-validation@sha256:a0620c2918f51cd7The line at the top of this page pins the label git:20261004.4b0ddb9, 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.
