Lowfat: a pluggable CLI filter cutting LLM token usage by 91.8%

zdkaster built Lowfat, an open-source CLI tool that strips noise from command output before it hits an LLM, reporting a 91.8% reduction in tokens on their own workload. For indie makers running LLM-powered dev tools or agents, token costs are a real budget line — a configurable filter at the CLI layer is a practical place to attack that. The pluggable design means it can adapt to different output formats rather than being a one-trick formatter.
