A new GitHub repository offers a Claude Code skill that dramatically reduces token usage by 75% while preserving full technical accuracy. The caveman mode, inspired by the viral observation that simplified language cuts LLM output significantly, translates normal Claude responses into a more concise, caveman-like style. This approach maintains all technical substance but eliminates filler words and pleasantries. 75% reduction in tokens translates to substantial cost savings on Claude output and faster response generation without sacrificing correctness.

The skill installs via `npx skills add JuliusBrussee/caveman` or the Claude plugin system, offering immediate practical benefits for developers seeking efficiency without compromising on technical depth.
