Geosql: A Claude/Codex skill for geospatial data

GeoSQL is a new skill for data scientists and analysts, enhancing Claude, Codex, and GitHub Copilot for geospatial data tasks on various platforms like PostGIS and BigQuery. It operates locally or self-hosted, offering a 4x improvement on geospatial tasks by incorporating a "map in the loop" for visual validation and correction. GeoSQL explores warehouse metadata, writes spatial SQL, includes cost checks, and validates geometry, with optional Dekart integration for map rendering.
