Advanced AI Prompt for Automated Canonical Logic and Self-Referential Auditing

Act as a Search Engine Indexing Engineer. Script a logic agent to brutally validate the canonicalization strategy across a massive [URL_LIST]. The agent must: 1) Cross-reference the 'Declared Canonical' injected in the [HTML_HEAD_DATA] against the actual requested URL to immediately flag missing self-referential canonicals on unique content. 2) Recursively trace and identify 'Canonical Chains' where URL A canonicalizes to B, and B canonicalizes to C. 3) Intersect the data to flag paradoxes where canonicalized URLs are simultaneously blocked by [ROBOTS_DATA] or marked with a 'noindex' directive, thereby preventing Google from passing signals. 4) Hunt for unauthorized 'Cross-Domain' canonicals, flagging them for severe security or hijacking risks. Output a CSV of 'Canonical Mismatches' and provide explicit programmatic rules for a CMS developer to implement bulletproof 'Auto-Generated Self-Referential Canonicals'.
