Caveman Code

1.93× fewer tokens on 25 matched coding tasks

A terminal coding agent measured at 1.93× fewer tokens than Codex CLI across 25 matched gpt-5.5 tasks, with 14/25 versus 15/25 tasks passing. Four compression layers sit under an autonomous goal loop across 20+ providers. Frozen since August 2026: still installable and working, no longer in active development.
