Compress natural language memory files (CLAUDE.md, todos, preferences) into caveman format to save input tokens. Preserves all technical substance, code, URLs, and structure. Compressed version overwrites the original file. Human-readable backup saved as FILE.original.md. Trigger: /caveman-compress FILEPATH or "compress memory file".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Caveman Compress ## Purpose Compress natural language files (CLAUDE.md, todos, preferences) into caveman-speak to reduce input tokens. Compressed version overwrites original. Human-readable backup saved as `<filename>.original.md`, but NOT beside the source file — it lives in an out-of-tree data dir (`$XDG_DATA_HOME/caveman-compress/backups/<parent-dir-name>/`, or `%LOCALAPPDATA%\caveman-compress\backups\<parent-dir-name>\` on Windows) so skill auto-loaders don't re-ingest it as a live file. ## Trigger `/caveman-compress <filepath>` or when user asks to compress a memory file. ## Process 1. The compression scripts live in `scripts/` (adjacent to this SKILL.md). If the path is not immediately available, search for `scripts/__main__.py` next to this SKILL.md. 2. From the directory containing this SKILL.md, run: python3 -m scripts <absolute_filepath> 3. The CLI will: - detect file type (no tokens) - call Claude to compress - validate output (no tokens) - if errors: cherry-pick fix with Claude (targeted fixes only, no recompression) - retry up to 2 times - if still failing after 2 retries: report error to user, leave original file untouched 4. Return result to user …

How to install
mdr add chinkan/rustfox/caveman-compress@sha256:3167d62440eee99cThe line at the top of this page pins the label git:20260804.0abefec, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
