What problem does it solve? Large project memory files like CLAUDE.md, todos, and preference notes are loaded into context on every session, consuming input tokens repeatedly. This Skill compresses those natural language files into a terse caveman-style 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 words, hedging, and redundant phrasing while keeping meaning intact. - Strict Preservation Rules: Code blocks, inline code, URLs, file paths, commands, headings, and YAML frontmatter are preserved exactly and verified by automated validation. - Safe Backup & Retry Workflow: The original file is backed up as FILE.original.md outside the source tree, validation failures trigger targeted fixes with up to 2 retries, and the original is restored if compression fails. - Use Case: A developer with a 1000-token CLAUDE.md runs the skill once, and every subsequent session loads the compressed version, saving hundreds of tokens per session permanently. ## Quick Start Ask the AI to run /caveman-compress on your CLAUDE.md file to compress it and create a human-readable backup.
