Modern AI models often produce overly verbose, jargon-heavy, or confusing text that requires extra effort to read. To combat this cognitive overload, developers can use the output styles feature in Claude Code. By tailoring how the AI communicates, you can dramatically improve readability and efficiency based on your current task, project complexity, or personal energy level.

Setting Up and Customizing Output Styles

Output styles allow you to adjust the tone, depth, and format of AI responses. You can configure styles directly within Claude Code through a few simple steps:

• Tag the guide (e.g., @claude code guide) and ask it to add or convert text into a new output style.
• Use the /config command to search for and select your active output style.
• Use /branch during a conversation to test alternative communication styles whenever you encounter confusing output.

Key Output Styles for Different Use Cases

Different tasks and projects benefit from customized communication approaches:

• Explain Like I’m 5 (ELI5): Simplifies complex technical jargon into easy-to-understand concepts after a long day.
• Exploratory / Explanatory: Excellent for onboarding new engineers to a codebase. The AI explains architectural decisions, language features, and logic alongside its code changes.
• Simplified Technical English (ASD-STE-100): Uses standardized language rules to deliver clear, unambiguous technical explanations without fluff.

Per-Project Persistence and Strategy

Claude Code saves output style preferences per project inside the .claude/settings.local.json file. This allows developers to use concise, short styles for highly familiar projects while maintaining detailed explanatory styles for unfamiliar or complex codebases. As default AI outputs grow more complex, actively managing output styles is becoming an essential practice to save time and reduce mental fatigue.
