What problem does it solve? Project memory files like CLAUDE.md, todos, and preferences load on every AI session start, and large files consume input tokens repeatedly. This Skill compresses those natural language files into a terse caveman format, cutting token usage by roughly 46% on average while preserving all technical substance. ## Core Features & Use Cases - Token-reducing compression: Rewrites prose by removing articles, filler, hedging, and redundant phrasing while keeping meaning intact. - Strict preservation rules: Code blocks, inline code, URLs, file paths, commands, headings, and technical terms are preserved exactly, with automated validation and targeted retry fixes. - Safe backup workflow: The original file is saved as FILE.original.md before the compressed version overwrites it, and compression aborts if a backup already exists. - Use Case: Run the skill on a 700-token CLAUDE.md preferences file to shrink it to about 285 tokens, so every subsequent session loads fewer tokens automatically. ## Quick Start Ask the AI to run /caveman:compress on your CLAUDE.md file to compress it and create a human-readable backup.
