Thank you for the changes, I will be reviewing them. Meanwhile, Would it be okay to add a small description of changes you did along with some additional changes in eval.go files. This will ensure we are consistent with the structure of the PRs.

Hi, I think I meant different files but in the commands folder themselves. We can move away from subdirectory.

@apoorvyadav1111 I just checked there was one typo in COMMAND.md subcommands error section. it should be subcommand at the place of sucommand.

I’m creating a new PR. Which issue should I link it to?
