What it catches

Flag	What it means
`missing-alt`	The `alt` attribute is entirely absent — a WCAG hard failure
`empty-alt-suspect`	`alt=""` without `role="presentation"` or `aria-hidden="true"` (often unintentional)
`decorative-should-be-empty`	Image marked decorative but still has alt text
`alt-too-long`	Alt over 150 chars (Lighthouse warning threshold)
`filename-as-alt`	`alt="IMG_1234.jpg"` — useless placeholder

Input

{ "url": "https://example.com" }
