Hi @imDarshanGK,

I'd like to work on #938.

My plan is to implement deduplication logic for the tests and tooling workflow, ensuring duplicate entries are handled efficiently while preserving existing behavior and following the project's coding style.

If the issue is available, I'd appreciate being assigned.

Thanks!
