Agent Skills: schema-entity-graph

Build and assemble a complete Schema.org entity graph for Astro lead-gen sites, driven from siteConfig. Use whenever a project needs JSON-LD structured data — new site setup, schema implementation, adding schema to existing pages, or when the user mentions entity graph, schema components, JSON-LD setup, structured data system, or knowledge graph. Also triggers when building a new Astro project that needs SEO schema, implementing service/area/blog schemas, or connecting business + person + service entities. Works with the schema-audit skill (audit validates rules; this skill builds the implementation). Always use this skill for schema assembly — never write schema components from scratch without it.
