automatically better for every production
system.
Run your project's tests and review
behavior before accepting large AI-generated
changes.
Debugging

Share Error
Provide the error message,
stack trace or failing code.
2
Analyze
Ask the AI to identify

possible solutions.
4
Verify
Run tests and confirm that
the fix actually works.
