Install
With your agent
Install OMGSkills skill "juliusbrussee/caveman:compress" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/JuliusBrussee/caveman /tmp/caveman && ln -s /tmp/caveman/skills/caveman-compress ~/.claude/skills/caveman-compressFrom README
Caveman Compress Purpose Data leaves the machine. Compression sends the file's full text to the model provider that scripts/compress.py is configured for: the claude CLI, the Anthropic API, or an OpenAI-compatible endpoint. Files whose names look like secrets (.env, credentials, secrets, .netrc, …) are refused before they are read. Don't compress a file the provider shouldn't see. Compress natural language files (CLAUDE.md, todos, preferences) into caveman-speak to reduce input tokens. Compressed version overwrites original. Human-readable backup saved as .original.md, but NOT beside the source file — it lives in an out-of-tree data dir ($XDGDATAHOME/caveman-compress/backups/ /, or %LOCALAPPDATA%\caveman-compress\backups\ \ on Windows) so skill auto-loaders don't re-ingest it as a live file. Trigger /caveman-compress or when user asks to compress a memory file. Requires an explicit filepath.
