Show HN: Lowfat – pluggable CLI filter that saved 91.8% of my LLM tokens (github.com) AI

Show HN’s lowfat is a lightweight, extensible CLI filter that trims unnecessary command output before it reaches an AI agent, aiming to reduce LLM token usage and costs (the author claims 91.8% savings). It supports UNIX-style piping, local-first use with no telemetry, and integration via Claude Code hooks, shell environment activation, or an OpenCode plugin, with commands like `lowfat stats` and `lowfat history` to track savings and tune behavior.
