What is contextzip and how does it work?

contextzip is a CLI tool that automatically filters bloated stack traces from Node.js (and similar) outputs, stripping internal frames to save AI context tokens. Install via cargo or npx; it hooks into your shell.

Does contextzip work with Cursor or Claude?

Yes — pipe any command output through it, and your AI sees clean traces. Zero integration needed; just eval the init script.

Is contextzip safe for production logs?

For dev/debug, perfect. Prod? Test patterns — it keeps app frames, drops internals. Won't break Sentry or ELK if aliased right.
