Checklist

Please make sure to review and check all of these items:

• PR's title starts with a category (e.g. [Bugfix], [IR], [Builder], etc)
• All changes have test coverage (It would be good to provide ~2 different test cases to test the robustness of your code)
• Pass the formatting check locally
• Code is well-documented
