Introduction
Install 21 GIS workflow skills for Hermes Agent and connect the GIS tools you already use.
Hermes GIS Skills is a versioned library of 21 GIS workflow skills for the open-source Hermes Agent from Nous Research. The library was developed through Mercator, a working Hermes profile focused on ArcGIS, open-source GIS, spatial AI, cartography, and GIS product delivery.
The skills are plain Markdown with YAML frontmatter. You can inspect them, version them, fork them, and load them into any Hermes profile.
Independent project
Hermes Agent is built by Nous Research. Hermes GIS Skills is an independent community project and is not affiliated with or endorsed by Nous Research or Esri.
What the repository includes
- 21 GIS skills for source validation, data QA, ArcGIS and open-source app architecture, cartography, dashboard QA, spatial AI, and product delivery.
- 116 focused references capturing implementation patterns and lessons from GIS application and data work.
- A machine-readable
catalog.json. - Installation, security, contribution, release, and validation documentation.
- A dependency-free validator that checks package structure, references, portability, and common secret patterns.
What it does not install
Cloning the repository does not install QGIS, PostGIS, GDAL, DuckDB, Tippecanoe, ArcGIS credentials, MCP servers, or executable GIS tools. Skills teach Hermes what workflow to follow; tools and local software provide the execution layer and are configured separately.
