lighthouse.agentic-audit-failed

What to change

A finding of this rule on a page carries the exact edits for that page: the markup it quotes, and what to write instead.

When it runs

Runs with --lighthouse, on the command or the local server. Info is a best practice: worth doing, rarely urgent, and --no-info leaves it out. Each finding takes 1 point off the page's score.

The severity here is the rule's usual one: a finding can be raised or lowered when the page gives a reason.

Run it, or skip it

Check a page for this rule alone, after a fix for instance:

npx @rivi-software/agentic-seo-check audit https://example.com --lighthouse --rule lighthouse.agentic-audit-failed

Or from an assistant, with the MCP tool seo_audit_page:

{
  "url": "https://example.com",
  "lighthouse": true,
  "rules": [
    "lighthouse.agentic-audit-failed"
  ]
}

To leave it out of an audit, pass --disable lighthouse.agentic-audit-failed on the command, or disableRules: ["lighthouse.agentic-audit-failed"] to a tool.
