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."
72% fewer tokens. Same fix.
🗣️ Normal Claude — 41 tokens
"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 — 12 tokens
"Bug in auth middleware. Token expiry check use < not <=. Fix:"
71% fewer tokens. More direct.

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

What it does

Caveman Smart

💀
Kill the Fluff

Articles (a, an, the), pleasantries, and hedging — all gone. "I'd be happy to help" dies here.

🧠
Keep the Brain

Technical terms, error messages, code blocks, and git commits always written normally. Caveman not stupid.

⚡
3x Faster

Fewer tokens to generate means faster responses. Less waiting. More shipping.

💰
75% Cost Cut

Claude API billed per token. Cut 75% output tokens = cut 75% output cost. Math easy.

The Numbers

Why
Caveman Win

Normal LLM wastes tokens on garbage. "I'd be happy to help you with that" — 8 wasted tokens. "The reason this is happening is because" — 7 wasted tokens. Caveman say what need saying. Then stop.
