What problem does it solve? Long natural language memory files like CLAUDE.md, todos, and preference notes consume excessive input tokens every time they are loaded into an AI context window, increasing cost and reducing available context. ## Core Features & Use Cases - Token Reduction: Rewrites prose into terse caveman-style fragments by removing articles, filler words, pleasantries, and hedging language. - Safe Compression: Preserves code blocks, inline code, URLs, file paths, commands, technical terms, and markdown structure exactly as-is. - Automatic Backup: Saves the human-readable original as FILE.original.md before overwriting the compressed version. - Validated Output: Runs validation with up to 2 targeted retry fixes, leaving the original untouched if compression fails. - Use Case: Compress a lengthy CLAUDE.md project memory file before starting a session so the AI loads the same instructions using far fewer tokens. ## Quick Start Ask the AI to compress your memory file by running the compress skill on the absolute path of your CLAUDE.md or notes file.
