Curated skill packages for Earth and space system models. Each repo is a self-contained, progressive-disclosure knowledge package: a SKILL.md routing hub plus reference/ deep-dive docs covering install, compile, run, modify, debug, and contribute.

These repos are designed to be loaded as skills by AI coding agents (Claude Code, Codex, Cursor, etc.) and to serve as durable, human-readable references for researchers and developers.

These repos are maintained by collaborators in their own namespaces. They follow the same progressive-disclosure skill pattern and are part of the broader effort.
