What it does
Form Validation is an agent skill from thedaviddias/Front-End-Checklist. 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.
Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
It sits in Frontend & Design, covering Forms and validation and Accessibility. It works with React. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it

Example prompts
- “/form-validation”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Form Validation loads about 633 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 255 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
requiredoraria-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
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
Explain how accessible form validation improves user experience and ensures all users can understand and correct errors.
Code Review
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.
