caveman

Caveman is a skill and proxy that cuts token use by making coding agents answer tersely and shrink the text they read, for developers and heavy AI users.

What it is good for

  • Cutting the cost of long coding agent sessions
  • Shortening answers from Claude Code and similar agents
  • Reducing the size of logs and test output an agent reads
  • Lowering token spend on repeated coding tasks
