Description
Hey HN! I've been building Claurst - a clean-room implementation of Claude Code in Rust, with extra features to make my ideal agentic Open-Source AI CLI. It's WIP and rough, but I'm shipping a lot to make it amaze amaze amaze.Inspired by this HN post [1] I saw a few hours ago about caveman speak for token-efficient output, I added /Caveman and /Rocky (from project Hail Mary) to Claurst.Caveman grammar drops ~70% of output tokens keeping technical substance and Rocky brings a close compression with more personality. Both are first-class slash commands with three levels: lite, full, ultra.It's fun, makes you happy and saves tokens :DWould love for you to try it out and get feedback![1] - https://news.ycombinator.com/item?id=47647455

Could you build this?
Yes It is an open-source CLI agent written in Rust that communicates with the Claude API using specialized system prompt compression ('caveman speak') and local file execution tools.
