Example response:
Thanks for the review! > Consider using async/await instead of promises Good point! I've updated the code to use async/await for better readability. > The tests are missing edge cases You're right. I've added tests for null inputs and error handling. Let me know if there's anything else!
Every project has different rules. Always read CONTRIBUTING.md first!
Break big changes into smaller, reviewable chunks.
One PR = One logical change. Don't fix multiple unrelated issues.
Match the project's coding style and architecture.
Always test before pushing!
Be clear, polite, and professional in all interactions.
