A new open-source tool called Caveman has gained significant traction on GitHub, with over 54,000 stars, for its ability to reduce token usage in AI coding assistants. The tool functions as a system prompt that instructs models like Claude Code to adopt a terse, telegraphic style, cutting down on filler and preamble. While independent benchmarks show varying results, Caveman offers a one-line installation that auto-detects and configures over 30 different AI agents, including Cursor and Gemini CLI, and provides companion utilities for further compression.
