lowfat

lowfat is a lightweight CLI tool designed to reduce AI token costs by filtering out unnecessary and verbose command-line output before it reaches your AI agents. It intercepts common commands like git, docker, and ls, condensing the raw text without losing core signals. Key features include local-first execution with zero telemetry, UNIX-style composability, and customizable compression levels (lite, full, ultra). It seamlessly integrates with AI agent environments such as Claude Code, OpenCode, and Pi.
