 description: Use this skill when the user wants to run core hotdata CLI commands — auth, workspaces, instant databases, tables, basic SQL query, database context (context:DATAMODEL), jobs, datasources/ingests/runs (pull external data), and skill install. Activate for "run hotdata", "list workspaces", "list databases", "instant database", "load parquet", "list tables", "show table columns", "execute a query", "database context", "context:DATAMODEL", "ingest", "datasource", "ingest run", "show a run", "schedule an ingest", "import data from", "connect a data source", "connector", "pull data from postgres/mysql/an API/S3 buckets/Iceberg", or general Hotdata CLI usage. This skill bundles three specialized guides under subskills/, loaded on demand: read subskills/search/SKILL.md for full-text/vector search and retrieval indexes, subskills/analytics/SKILL.md for OLAP analytics, query history, stored results, and Chain materializations, and subskills/geospatial/SKILL.md for geospatial/GIS.

 description: Use this skill when the user wants OLAP-style SQL analytics in Hotdata — aggregations, GROUP BY, JOINs, reporting, exploratory queries, query run history, stored results, or materialized follow-up tables (Chain into instant databases). Activate for "analyze", "aggregate", "rollup", "pivot", "report", "metrics", "GROUP BY", "query history", "past queries", "query runs", "stored results", "materialize", "chain", "intermediate table", or sorted indexes for filters/range scans. Do not load for BM25/vector search or geospatial SQL — use hotdata-search or hotdata-geospatial. Requires the core hotdata skill for tables and auth.

 description: Use this skill when the user wants full-text search, BM25 keyword search, vector similarity search, semantic search, embeddings, or retrieval indexes in Hotdata. Activate for "hotdata search", "BM25", "full-text", "vector search", "semantic search", "similarity", "embedding", "embedding provider", "create an index" (bm25 or vector), "list indexes" for search, or SQL using bm25_search or vector_distance. Do not load for general SQL analytics (aggregations, GROUP BY) or geospatial work — use hotdata-analytics or hotdata-geospatial instead. Requires the core hotdata skill for auth and workspace basics.
