I loved the idea behind "caveman" but didn't want a caveman. So I gave it a Kevin.

An author added conciseness guidance to their AI prompting instructions, emphasizing that avoiding over-explanation builds confidence and trust with audiences. After experimenting with the "caveman" technique—which strips outputs to bare essentials—the author adopted a middle approach that maintains some personality while reducing verbosity compared to Claude's default style.

Detailed Analysis

A Reddit user on the r/ClaudeAI community has shared a prompt engineering solution to one of the most commonly cited frustrations with Claude: its tendency toward verbose, over-explained responses. The user modified their CLAUDE.md configuration file — a persistent instruction document that shapes Claude's behavior across sessions — by inserting a reference to Kevin Malone from the television series *The Office*, whose comedic persona centers on radical economy of language. The instruction explicitly frames over-explanation as a failure mode reflecting both low confidence and distrust of the audience, and includes a practical self-check heuristic for writing tasks: ask whether additional context genuinely serves the reader or merely narrates the obvious.

The post situates itself in relation to a prior community trend referred to as the "caveman" approach, which appears to be a known prompt engineering technique designed to strip Claude's responses down to minimal, bare-bones output. The user validates this approach conceptually but finds it too aggressive, sacrificing the conversational personality and collaborative dynamic that makes Claude useful for their workflow. The Kevin-based framing represents an attempt to locate a midpoint — preserving wit, back-and-forth engagement, and some personality while eliminating the padding, redundancy, and performative thoroughness that inflate Claude's default outputs. The user reports measurable improvements not only in response quality but also in context window efficiency, which has practical cost and performance implications for heavy users.

This kind of user-driven behavioral tuning through system prompts and configuration files reflects a broader pattern in how power users interact with large language models. Rather than accepting default model behavior, experienced users increasingly treat CLAUDE.md and equivalent configuration layers as a form of lightweight fine-tuning, encoding workflow-specific norms directly into the model's operating context. The fact that a pop culture reference — specifically a character defined by linguistic minimalism — can serve as an effective behavioral anchor illustrates how Claude's instruction-following capabilities respond to culturally resonant framing, not just technical directives.

The verbosity problem the user describes is well-documented among Claude users and represents a meaningful design tension for Anthropic. Claude's expressive, thorough default style reflects training choices that optimize for helpfulness and completeness, but these same choices can produce responses that bury key information in scaffolding, consume context tokens unnecessarily, and slow down high-iteration workflows. The user's note that they are on the Max 20x subscription plan is relevant: heavier users with more sophisticated workflows are precisely the audience most sensitive to context efficiency, and their prompt engineering workarounds signal areas where model defaults may diverge from power-user preferences.

The community discussion the post invites — asking where others have landed on output wordiness and structure — reflects the degree to which response formatting and length have become active, ongoing calibration problems for Claude's user base. Unlike one-time configuration choices, verbosity tuning tends to be workflow-specific and iterative, with users experimenting across different task types, agent architectures, and interaction styles. The Kevin Malone heuristic stands out as a creative, memorable solution to a recurring friction point, and its reported success in both agent-written documents and direct responses suggests that anthropomorphic, culturally grounded framing can be a durable and effective tool in the prompt engineer's repertoire.
