Content-aware output compression for AI coding assistants. 36 specialized processors cut CLI output tokens by 60-99% (git, pytest, npm, terraform, kubectl, docker, and more) without losing errors, diffs, or stack traces.

**Keep the signal. Stop rereading the same failures.**

Token-Saver compresses the terminal output your AI coding assistant reads —
`git diff`, `pytest`, `npm install`, `terraform plan`, `kubectl`, `docker` — to
leave more room for the code, instructions, and next decision. Compression runs
locally, without another model call or an output upload.

**New in v3: [Delta](#delta-changes-between-runs).** Run your tests,
edit, run again: see which failures are new, changed, or unchanged. Fresh
diagnostics keep their full details; repeated ones can become a short inventory,
with details available on demand. Delta is an experimental, opt-in feature in
3.0.0 for supported pytest and Ruff commands in Claude Code.
