About Caveman

Why Caveman Exist

Based on a viral observation: caveman-speak dramatically reduces LLM token usage without losing technical substance.

When you prompt Claude with caveman-style constraints — drop articles, kill pleasantries, eliminate hedging — the model produces responses that are technically identical but radically shorter.

So we made it a one-line install for Claude Code.

What Gets Cut

// These waste tokens every single call:
"I'd be happy to help you with that"     // +8 tokens
"The reason this is happening is because"  // +7 tokens
"I would recommend that you consider"     // +7 tokens
"Sure, let me take a look at that for you" // +10 tokens

// Caveman says what needs saying. Then stops.

What Gets Kept

Everything technically important is preserved verbatim: code blocks, technical terminology, error messages, command syntax, git commits, PR descriptions.

"If removing it doesn't change what you'd do next, it's gone."
