audit_public_site
Audit public site
Use this for a bounded, sitemap-first audit of a public website the user owns or is authorized to inspect. It fetches at most 8 same-origin HTML pages per call, respects robots.txt, and returns compact page summaries plus deduplicated findings. It does not recursively follow HTML links, authenticate, execute JavaScript, fetch assets, or run site-wide link checks. Use page_offset to continue when more sitemap pages remain.

Use this when the user provides one live public webpage URL. Fetches one bounded static HTML response, then runs HTML validation, SEO/accessibility-signal, and JSON-LD syntax checks. It checks links only when requested and does not crawl, execute JavaScript, authenticate, or fetch linked stylesheets. Use only URLs the user owns or is authorized to inspect.
