The article discusses a tool called Caveman, which is a skill/plugin for various AI coding agents that makes them communicate in a concise, caveman-like language, reducing output tokens by 65%. This is achieved by dropping filler words and keeping only the essential information, without affecting code, commands, or errors. The tool is designed to work with multiple agents and can be installed with a single command. The goal is to make the agents more efficient and cost-effective.
