Caveman is a one-line installable Claude Code skill by Julius Brussee that instructs Claude to respond in ultra-compressed telegraphic language — short imperative verbs, no filler words, minimal articles — while preserving technical accuracy. The conceit is absurd: make Claude sound like a caveman. The result is practical: roughly 75% fewer output tokens per response. This matters because Claude's usage limits are token-based. Power users and teams hitting rate limits on Claude Code subscriptions have found that caveman-style output dramatically extends how many interactions they can run per session. The Hacker News thread hit 333 points the day it launched, with developers sharing variations and reporting measurable drops in token consumption for coding workflows. The project also spawned a fork (Caveman-Claude by om-patel5) that packages it as a higher-performance optimization layer with additional context-compression techniques. What started as a joke about caveman grammar is becoming a serious prompt-engineering pattern for token efficiency.

Contentful is the enterprise headless CMS with content modeling, localization, and a mature API. The market leader for enterprise content infrastructure.
Reviewer scorecard
“I tested this against my normal Claude Code sessions and the token reduction is real — closer to 60-70% in practice, but that's still significant. For long refactoring sessions where I'm hitting usage walls, this is now a permanent part of my setup. One-line install is the right distribution model.”
“Mature API, excellent SDKs, and the content model is flexible. The enterprise choice for headless CMS.”
“This is a workaround for Anthropic's pricing model, not a solution. The caveman syntax makes outputs harder to read and copy-paste — you'll spend cognitive overhead parsing the response. And if Anthropic changes how usage limits work, this approach becomes irrelevant overnight. It's a clever hack, not a durable tool.”
“Expensive for what it is. Sanity and Payload offer better DX at lower cost. Only justified for enterprise compliance needs.”
“This is a data point in the larger story about prompt efficiency becoming a discipline. As token costs dominate AI budgets, compressing output without losing semantics will be a genuine engineering skill. Caveman is silly — but the underlying insight about output verbosity being a lever is serious.”
“For any creative workflow — writing, design iteration, content generation — caveman output is actively counterproductive. The compressed style strips the nuance and polish from responses that make AI useful for creative work. This is a developer tool with a very specific use case.”
“The editor experience is functional but uninspiring. Sanity's customizable studio is more pleasant to work in.”
