Caveman Claude Open-Sourced: Prompt Saves 72% Tokens

techNmak · x · 2026-07-05

An open-source project named "Caveman Claude" has garnered 84,300 stars. By using a specific prompt, it forces Claude to respond in minimalist, telegraphic language, reducing token consumption by roughly 72% while maintaining accuracy.

An example shows standard Claude using 69 tokens to explain a React re-render issue, while the Caveman version uses only 19 tokens to deliver the same conclusion ("new object reference → inline object prop → triggers re-render → wrap with useMemo").
