The main tool appears to do local mineral mapping, but the package also bundles undisclosed credential and network helpers that do not fit the documented offline workflow.
Review this skill carefully before installing. Its normal command-line workflow appears local, but the package contains extra helper code for credentials, external geocoding, downloads, and home-directory caches that the user-facing skill description does not explain. Avoid using it in environments with sensitive .netrc, geospatial project names, or shared Earthdata/OpenAI-style credentials unless the publisher removes or clearly scopes those helpers.
