 "what": "Caveman is a skill and proxy for coding agents that cuts tokens by making the agent talk tersely and read less, while code stays exact. The README reports 33.2% fewer input tokens across 54 Claude Code runs and links an Adobe Research paper on caveman-style output; it also links a page listing every case where caveman loses. It installs as a skill, a Claude Code plugin, a Gemini CLI extension or an all-agents installer, with an optional free Auto model router.",
 "why": "115k stars, talked about in 2 AI sources we track",
 "language": "Go",
 "requirements": [
  "A coding agent such as Claude Code, Codex or Gemini CLI",
  "Node.js for the npx installs (22.13+ for the all-agents installer)"
 ],
 "audience_note": "Developers who pay per token for Claude Code, Codex or Gemini CLI and want shorter answers and smaller context without losing correctness.",
