Forms are where trust is won or lost.

**ARIA** means **Accessible Rich Internet Applications**, a standard that helps assistive technology understand interface semantics. https://www.w3.org/WAI/standards-guidelines/aria/

This guide helps you fix form issues without feeling lost, using **KaBOOM Agentic Devtools**.

## Quick Terms

- **Form label**: Text that explains what input is for.
- **Validation**: Rules that check input quality.
- **Application Programming Interface (API)**: Structured channel between frontend and backend systems. https://developer.mozilla.org/en-US/docs/Glossary/API
- **ARIA attribute**: Extra accessibility metadata for user interface elements.

## The Problem You Are Solving

You want forms that:

- are easy to fill,
- are accessible,
- and submit reliably.

## Step-by-Step with KaBOOM Agentic Devtools

### Step 1. Inspect form structure

```js
analyze({what: "forms"})
analyze({what: "forms", selector: "#checkout-form"})
```

### Step 2. Check current form state

```js
analyze({what: "form_state", selector: "#checkout-form"})
```

Use this when fields behave differently than expected.

### Step 3. Validate accessibility and semantics

```js
analyze({what: "form_validation", summary: true})
analyze({what: "accessibility", scope: "#checkout-form", summary: true})
```

### Step 4. Reproduce the bug consistently

```js
interact({
  what: "fill_form_and_submit",
  fields: [
    {selector: "label=Email", value: "bad-email"},
    {selector: "label=Phone", value: "123"}
  ],
  submit_selector: "text=Submit"
})
```

## Common Fixes

- Add missing labels linked to inputs.
- Ensure error messages are specific and visible.
- Keep validation rules consistent across client and server.
