24 metadata & bibliometrics skills. Trigger: DOI resolution, citation metrics, author disambiguation, bibliometrics. Design: metadata APIs and bibliometric analysis tools for scholarly records. When the user wants a full-page metadata audit or implementation across discovery, search intent, title, description, canonical, robots, hreflang, Open Graph, Twitter Cards, code or CMS changes, build validation, rendered HTML, production verification, localization, or post-release observation. Also use for "metadata audit," "sitewide meta optimization," "metadata implementation," "meta robots," "hreflang," "viewport," or "charset." For an isolated title, description, heading, Open Graph, or Twitter Card task, use its specialist skill directly.
The two skills share the name 'metadata' but address entirely different domains. The first is a marketing/SEO skill for auditing and implementing HTML page metadata (titles, descriptions, canonical, hreflang, Open Graph). The second is a research skill that acts as a router for 24 bibliometric and scholarly metadata tools (CrossRef, ORCID, Zotero, etc.). They do not overlap in procedure, inputs, or outputs, and neither is a reproduction of the other.
