tgaz-sqlite

Query and explore the TGAZ (Temporal Gazetteer) SQLite database of 82,000+ historical Chinese placenames spanning 763 BCE to 1911 CE. Use this skill whenever the user asks about historical Chinese places, administrative geography, dynastic jurisdictions, place name evolution, or wants to query tgaz.db. Also trigger when the user mentions CHGIS, TGAZ, historical gazetteer, Chinese historical GIS, or asks questions like "what was X called in dynasty Y", "what counties existed in year Z", "where was X located", or any spatial/temporal query about Chinese historical geography. This skill is relevant even for casual questions like "tell me about ancient Chang'an" or "Tang dynasty cities near the Yellow River".
