What problem does it solve? Web pages often ship with duplicate titles, missing canonical tags, broken Open Graph images, or invalid structured data, which hurts search indexing and link sharing. This Skill applies a prioritized rule set to catch and fix those metadata issues with minimal diffs. ## Core Features & Use Cases - Prioritized rule categories: Eight ranked categories covering correctness, titles, canonical and indexing, social cards, icons, structured data, locale, and tool boundaries. - File review mode: Point it at a file to get violations quoted line-by-line, why each matters, and a concrete code-level fix. - Framework-agnostic constraints: Works with Next.js metadata API, react-helmet, or manual head tags without migrating libraries. - Use Case: Before launching a marketing page, run a review to confirm the title, description, canonical, og:url, and Twitter card all agree and use absolute image URLs. ## Quick Start Ask the assistant to review your page's metadata file against the fixing-metadata rules and report violations with fixes.
