Overview
Caveman is a tool for coding agents designed to reduce token consumption by simplifying output. It consists of two parts: skills and agents. The skills component is a rule file that enables agents to answer questions in a concise manner, suitable for over 30 agents. The agent component runs locally on your machine and compresses content read by the agent, such as logs, test outputs, JSON, etc. Caveman can significantly reduce token usage, thereby lowering costs while maintaining output accuracy.
