What shipped.

First documented cut of Hermes for GIS, the configuration behind the Mercator agent on the Hermes agent.

Added

• GIS toolset: esri (feature queries, geocode, portal search), open-data (public portal search and fetch), and postgis (read-only spatial SQL)
• Skill library: 21 agentskills.io skills for service validation, app scaffolds, cartography, QA pipelines, and spatial AI, in ~/.hermes/skills/gis/
• MCP servers: Esri, Census, open data, and research
• Local stack: PostGIS gis_lab, QGIS, GDAL, DuckDB, Tippecanoe, and a Python geo environment

Compatibility

• Requires the Hermes agent (Nous Research)
• Model-agnostic; runs on the provider configured in the profile

Known limitations

• esri covers Feature Layers and geocoding; raster support is planned
• postgis assumes a read-only role, so write operations are intentionally not exposed
• The skills repo is not published yet
