Caveman
Julius Brussee
Coding agents often spend many tokens explaining what they are doing, even when a short answer would be enough. Caveman changes the agent's writing style so replies are compressed while code, paths, commands, and technical details stay intact. Shorter replies can reduce output-token usage, cost less to read back into a long conversation, and make the session easier to scan. It mainly changes how much the agent says; it does not make the underlying model smaller or guarantee the same saving on every coding task.
Best for
People who want concise agent replies, lower conversational token usage, and less text between code changes.

Check before installing
The repository's benchmark measures specific tasks and configurations, so treat its percentage savings as examples rather than a guarantee. Use a less aggressive mode when security explanations or destructive actions need more context.
