Caveman Skill Slashes Claude Code Tokens

The meme turned into a real utility because the core insight is practical: a lot of agent chatter is pure token waste. The catch is that this mostly saves on output, so it helps most in repetitive coding workflows, not in context-heavy sessions.

• –The repo’s benchmarks show a 65% average reduction across 10 real tasks, but the gains vary widely by prompt
• –It is most useful for code reviews, commit messages, summaries, and iterative debugging where brevity does not hurt accuracy
• –The broader install story matters more than the joke: it supports Claude Code, Codex, Cursor, Windsurf, Copilot, Gemini CLI, and more
• –The `caveman-compress` feature extends savings into input tokens by rewriting memory files, which is where the bigger session-level wins can show up
• –The project is honest about tradeoffs, with auto-clarity rules for cases where terse output would be risky or ambiguous
