# Token-Saver

> Content-aware output compression for AI coding assistants. A Claude Code
> and Antigravity CLI plugin that intercepts verbose CLI command output
> (git, pytest, npm, terraform, kubectl, docker, and more) and compresses it
> deterministically before it reaches the model, using 36 specialized
> processors — one per tool family. Compression runs locally without LLM
> calls or output uploads. An optional release check contacts GitHub. Savings
> depend on the output and use character-based token estimates. Error
> preservation is covered by representative fixtures and configurable limits.
