opencode-tools

Because i mix them up all the time...

caveman

Ultra-compressed output mode — agent talks like caveman, cutting ~75% of output tokens while keeping technical substance. Ships caveman-commit, caveman-review, caveman-compress, caveman-help.

npx skills add JuliusBrussee/caveman

opencode has no hook system, so caveman does not auto-activate. Either trigger per session (/caveman, "caveman mode") or paste the always-on snippet from the repo README into ~/.config/opencode/AGENTS.md.
