      What this check looks for
    Description, as the server wrote it
    Run a fresh Web Scan audit of a public URL and return its score (0-100), grade, and every failing or warning check with its id, title and fix: the result is complete in itself. reportUrl is a shareable link only when the request carries a signed-in Web Scan token (reports are saved for signed-in users only); otherwise it is null and nothing is stored. fullReportUrl is always present: the full report on the website, to share with the user. Use this first, to find out what to fix on a live page. Takes about 5-15 seconds. Cannot scan localhost or private networks; use a deployed or preview URL.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Re-scan a URL after you deployed fixes and report, per check id, whether it now passes (fixed: true), plus the new score, the previous score, what is still failing with its fix, and allFixed. Use this after a change reaches production (or a public preview) instead of asking the user to re-scan. Pass the check ids from the scan or fix prompt; with none, every failing or warning check is returned. If a fix you made still shows fixed: false, the deploy may not be live yet or a CDN may be serving a cached page: wait about a minute and call again before concluding the fix failed.

    Why it is in this group

    • The name "get_report" says "get": a word for reading.
    Description, as the server wrote it
    Read a stored Web Scan report by its slug (the part after /r/ in a web-scan.agentmarket.lol/r/<slug> link) without re-scanning: score, grade, scan time and the failing or warning checks with fixes. Use this when the user shares a report link. Reports expire after two weeks; to check the current state of a site, use scan_url or verify_fixes instead.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
