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.

Claude Context is an MCP (Model Context Protocol) server built by Zilliz that gives Claude Code — and any compatible agent — semantic search over your entire codebase. Instead of dumping whole directories into context and burning tokens, Claude Context indexes your repo using hybrid BM25 + dense vector search backed by Zilliz Cloud's free tier, letting agents retrieve only the relevant code chunks for each query. The efficiency gains are real: early benchmarks show approximately 40% token reduction while maintaining retrieval quality. For large codebases where a single naive directory load can cost hundreds of thousands of tokens, this kind of targeted retrieval is the difference between feasible and infeasible agent runs. It supports multiple embedding providers (OpenAI, VoyageAI), file inclusion/exclusion rules, and runs seamlessly across Claude Code, Cursor, VS Code, Gemini CLI, and other MCP clients. With 8,900+ GitHub stars and trending aggressively today, Claude Context is filling an obvious gap: as codebases grow, brute-force context stuffing breaks down. Zilliz is essentially packaging their vector database expertise as a free dev tool to drive Zilliz Cloud adoption — a smart move that happens to be genuinely useful for the ecosystem.
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.”
“This solves the single biggest practical pain point with Claude Code on large repos — context overflow. The hybrid BM25 + dense vector approach means it doesn't just do keyword matching, it understands what you're actually looking for. 40% token savings at basically zero setup cost is a no-brainer.”
“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.”
“It adds a cloud dependency (Zilliz) and requires API keys for embeddings, which means your code traverses third-party infrastructure. For open-source projects that's fine, but for proprietary codebases this is a supply-chain consideration worth thinking through before you index your entire repo.”
“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.”
“Semantic code search as an MCP primitive is the right abstraction. Every coding agent will eventually need this, and standardizing it through MCP means the retrieval layer is composable across Claude Code, Cursor, Gemini CLI, and whatever agents emerge next. Zilliz is building the retrieval plumbing for the agentic era.”
“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.”
“Even for design-heavy repos with custom component libraries, finding the right existing component without manually hunting through folders is huge. If Claude can search your entire design system semantically and pull the exact component file, that's a real workflow upgrade for front-end work.”
