Top Claude Code Prompts
Battle-tested prompts for code review, debugging, refactoring, and feature planning. Copy, paste, and ship.
By Ryan Frizelle · 3 min read
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.
Code 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.Debugging
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.Feature 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.Refactoring
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.Performance audit
Audit this project for performance issues. Check bundle size, unnecessary re-renders, unoptimized images, missing caching, and slow database queries. Prioritize fixes by impact.Pro tip: always tell Claude Code what NOT to do. "Do not suggest style changes." "Do not refactor unrelated files." Constraints make the output way better.
The full course includes 20+ more prompts, plus the CLAUDE.md file that gives Claude Code permanent context about your project so every prompt works better.
