Core Features

Token Compression

Caveman compresses responses from AI coding agents by using a more concise style, reducing the number of tokens used while maintaining technical accuracy.

Source: README
Customizable Levels

Users can choose from different compression levels (lite, full, ultra, wenyan) to control the degree of compression based on their needs.

Source: README
Integration with Multiple Agents

Caveman integrates with a wide range of AI coding agents, including Claude Code, Codex, Gemini, Cursor, Windsurf, Cline, Copilot, and more, providing a versatile solution.
