GitHub 'caveman' AI token saver is a Go compression engine, not just a prompt

By PulseAugur Editorial · [1 sources] ·

A popular GitHub repository, marketed as a "caveman" AI skill that saves tokens, is actually a complex Go-based compression engine. The repository's marketing claims a 65% token reduction by having the AI "talk like a caveman," but this saving is achieved through a separate proxy tool that compresses input tokens by 33.2%. The "caveman" instructions themselves constitute only 1.3% of the repository's code. When tested with a real C# programming bug, the "ultracave" mode, which utilizes the proxy, achieved a 63.6% token reduction, validating the headline number but attributing it to the wrong component.

    I measured the viral "talk like a caveman" token saver. A two-word prompt got most of it.

    <p>There is a repo doing the rounds called <strong>caveman</strong>. Its pitch, verbatim from its own GitHub description:</p> <blockquote> <p>🪨 why use many token when few token do trick. Viral skill + proxy for coding agents that cuts 65% of tokens by talking like a caveman.</p>…
