Wikidata Search
Search Wikidata items, properties, and entities with keyword, semantic, and SPARQL queries
What You Can Do
You can search Wikidata using four complementary methods: keyword search via the Action API for label-based lookups, semantic/hybrid search through the Vector Database for fuzzy concept matching, direct entity retrieval via Special:EntityData for instant JSON data, and SPARQL queries through WDQS for complex graph relationships and reporting. Each method is optimized for different use cases—from quick entity lookups to multi-table data analysis across millions of linked facts.

You can rapidly diagnose medium-voltage distribution faults by analyzing protective device coordination sequences, load flow impacts, and field crew reports within Claude. The skill helps you distinguish between transient and permanent faults, identify whether issues stem from equipment failure or external factors, and validate remediation strategies before implementing risky switching operations. This accelerates your analytical phase so field resources can be deployed efficiently and switching decisions are made with confidence.

You can develop complete cost-of-service analyses that allocate utility operating expenses across customer classes based on NARUC cost causation methodology. The skill guides you through reclassifying costs by function (generation, transmission, distribution, customer service), selecting defensible allocation drivers tied to actual cost causation, and building rate structures that withstand regulatory scrutiny and legal challenge.
