caveman

Caveman strips the fluff from Claude Code responses. Install it with one command, activate with /caveman, and your AI assistant drops the pleasantries, hedging, and filler words while keeping full technical accuracy. Average savings: 65% fewer output tokens.

Three intensity levels: Lite keeps it professional but terse, Full drops articles and uses fragments, Ultra goes telegraphic. Code blocks, error messages, git commits, and technical terms pass through untouched. Only the natural language gets compressed. A companion tool (caveman-compress) rewrites your CLAUDE.md and memory files to cut input tokens too.

Works across 40+ AI coding agents, not just Claude Code. Cursor, Copilot, Windsurf, Cline, Codex, all supported. Heavy token users will feel the difference in both speed and cost.

The catch: it started as a meme (Kevin from The Office) but the benchmarks are real, backed by a 2026 arxiv paper. Ultra mode can be hard to read. And the savings are output tokens only, so your thinking/reasoning costs stay the same.
