Get the Caveman Playbook

Uber burned its entire 2026 AI budget in four months. Microsoft is revoking Claude Code. The bills got so big the giants are rationing AI — but they're plugging the wrong hole. This field guide is the free, open-source fix: caveman, a skill (70,000+ GitHub stars, MIT) that strips the verbosity an AI is paid by the word to produce, while keeping every line of code intact. Inside: the one-line install, all 6 commands, the 4 compression levels (lite/full/ultra/wenyan), the /caveman-compress trick that banks ~46% input-token savings on every session, the real benchmark table (−65% on average, up to −87%), and the safety net that keeps full clarity for anything risky. Plus the March 2026 arXiv paper proving the twist that makes this jaw-dropping: forcing the model to be brief improved large-model accuracy by +26 points and reversed the performance hierarchy. Cheaper AND smarter — the same move.
