Top Claude Code Prompts

Battle-tested prompts for code review, debugging, refactoring, and feature planning. Copy, paste, and ship.

Ryan FrizellePublished Mar 27, 2026

What you'll walk away with

  • Five prompts I run every day across real projects
  • The debugging prompt that hunts the cause, not the symptom
  • Why telling Claude what not to do makes the output better

The difference between getting mediocre output and incredible output from Claude Code comes down to how you prompt it. These are the exact prompts I use every day. They are tested across dozens of real projects.

01

Review your changes

Copy-paste promptCode review
Review the changes in this PR for security issues, performance problems, and code quality. Be specific about file and line numbers. Do not suggest style changes unless they affect readability.

02

Find the real cause

Copy-paste promptDebugging
This error is occurring: [paste error]. Investigate the root cause, do not just fix the symptom. Check related files and recent changes. Explain what caused it and why your fix works.

03

Plan before building

Copy-paste promptFeature planning
I want to add [feature]. Before writing any code, explore the codebase to understand existing patterns. Then propose an implementation plan with specific files to create or modify. Wait for my approval before building.

04

Clean up the code

Copy-paste promptRefactoring
Refactor [component/file] to be more maintainable. Keep the same external behavior. Explain each change and why it improves the code. Run tests after to verify nothing broke.

05

Speed it up

Audit this project for performance issues. Check bundle size, unnecessary re-renders, unoptimized images, missing caching, and slow database queries. Prioritize fixes by impact.
