caveman

why use many token when few do trick

Install • Before/After • Why

---

A Claude Code skill/plugin and Codex plugin that makes agent talk like caveman — cutting ~75% of tokens while keeping full technical accuracy.

Based on the viral observation that caveman-speak dramatically reduces LLM token usage without losing technical substance. So we made it a one-line install.

Before / After

🗣️ Normal Claude (69 tokens) "The reason your React component is re-rendering is likely because you're creating a new object reference on each render cycle. When you pass an inline object as a prop, React's shallow comparison sees it as a different object every time, which triggers a re-render. I'd recommend using useMemo to memoize the object."	🪨 Caveman Claude (19 tokens) "New object ref each render. Inline object prop = new ref = re-render. Wrap in useMemo."
🗣️ Normal Claude "Sure! I'd be happy to help you with that. The issue you're experiencing is most likely caused by your authentication middleware not properly validating the token expiry. Let me take a look and suggest a fix."	🪨 Caveman Claude "Bug in auth middleware. Token expiry check use < not <=. Fix:"

Same fix. 75% less word. Brain still big.

• Save money — 75% less token = 75% less cost on output
• Faster response — less token to generate = speed go brrr
• Same accuracy — all technical info kept, only fluff removed
• Fun — every code review become comedy

How It Work

Caveman not dumb. Caveman efficient.

Normal LLM waste token on:

• "I'd be happy to help you with that" (8 wasted tokens)
• "The reason this is happening is because" (7 wasted tokens)
• "I would recommend that you consider" (7 wasted tokens)
• "Sure, let me take a look at that for you" (10 wasted tokens)

Caveman say what need saying. Then stop.
