## What crux-compress does, in the publisher's words

CRUX-Compress, packaged as a plugin for Cursor, Claude Code, and Codex.

CRUX (Context Reduction Using X-encoding) compresses markdown rules, code files, images, and web pages into a dense notation that agents read directly, usually to about a quarter of the original tokens. The plugin carries the CRUX-Compress release unchanged except for the path and frontmatter changes listed in scripts/upstream-map.json.

This plugin is version 2.11.8, the same as the CRUX-Compress release it packages.

- Python 3 (python3 on PATH) for the hooks and the crux-utils and memory-index scripts.
- Downloads the release zip (or reads one given with --zip).
- Checks every file against the release's own.crux/crux-release-files.json checksums.
- Fetches files the zip leaves out from the release commit (see extraFiles and derived in the map).
