Show HN: Lowfat – pluggable CLI filter that saved 91.8% of my LLM tokens

Lowfat saved 4.1M of 4.4M raw tokens in the author’s two-month personal usage, running as an agent hook or shell wrapper to filter verbose CLI outputs from kubectl, docker, grep, and related commands.

Why it matters: HKR-H/K/R all pass: 91.8% savings is a strong hook, 4.1M/4.4M tokens plus the hook/wrapper mechanism add substance, and the cost/context pain is real for agent users. It is still a personal Show HN tool, so it stays near the featured threshold.
