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.

GSD (get-shit-done)
Spec-driven context engineering system for Claude Code — without the enterprise theater

GSD (get-shit-done) is a meta-prompting and context engineering system for Claude Code that imposes software engineering discipline on AI-assisted development. It replaces ad-hoc prompting with a five-step methodology — initialize, discuss, plan, execute, verify — that keeps context fresh and quality high across long, complex projects. The system works by loading specialized documentation strategically: project vision, requirements, roadmaps, and research are injected at the right phases rather than dumped into a single bloated context window. Planning produces XML-formatted task trees with built-in verification steps, and execution happens in waves — parallel where dependencies allow, sequential where they don't. Quality gates automatically detect schema drift, security regressions, and scope creep before they compound into bigger problems. For teams that have experienced the quality degradation that hits around hour three of a long Claude Code session, GSD's architecture of fresh context windows per phase is the fix. A Quick Mode handles ad-hoc tasks without the full planning overhead, making it practical for both exploratory work and milestone-driven development. It's MIT-licensed, JavaScript-based, and designed for solo developers and small teams who want spec-driven development without enterprise process overhead.
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.”
“GSD's five-step workflow (initialize → discuss → plan → execute → verify) with wave-based parallel execution and schema drift detection is the closest thing to a formal engineering discipline for Claude Code projects. The quality gates alone have saved me from shipping broken APIs multiple times.”
“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.”
“The upfront initialization and thorough planning phase is a real time investment — probably overkill for straightforward CRUD tasks or one-off scripts. GSD shines on complex, multi-milestone projects but adds ceremony that can slow you down when you just need something built quickly.”
“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.”
“GSD is one of the first serious attempts to bring software engineering discipline to AI-assisted development — not just prompting tricks but a reproducible methodology with verification steps and context management. As AI coding scales, the teams with structured workflows like this will outproduce those freewheeling with prompts.”
“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 as a non-developer building internal tools, GSD's discussion and planning phase surfaces requirements I hadn't thought of before any code gets written. Describing what I want built and watching it execute reliably — with a verify step confirming it actually works — changes how I think about building with AI.”
