Show HN: Lowfat – pluggable CLI filter that saved 91.8% of my LLM tokens
TL;DR
Hi HN, Not sure if anyone would be interested. But, just wanted to share that I've been maintaining my small tool called 'lowfat' that helps me filters some of my verbose CLI output. It's a single binary, works as an agent hook or a shell wrapper. It has a plugin system to customize filters per command.
Nauti's Take
Genuinely useful: Lowfat tackles a real problem — agents drown in verbose CLI output, and 90%+ token savings on kubectl or grep is a concrete lever for cost and speed. The catch: filtering output risks stripping the one detail the agent actually needed, so the plugin rules have to be solid.
Nauti's take: a clever tool for anyone working heavily with CLI agents, but spot-check critical commands unfiltered now and then.
