Code Reviews Comments Convention

A convention to clarify the intention of a comment in a Pull Request (PR) review using prefixes.

Although it is possible to express the intent in the way the comment is written, it is easier to do so with a simple prefix. Not only it requires less words but it is also easier to take a quick look at the comments and understand what is the intention/meaning of each one.

My rule of thumb is, only reviews that include [req] and/or [q] should Reject the PR. In other cases just make the review a Comment or Approve.


[req] (requested change)

Reviewer believes something should be changed.

[nth] (nice to have)

Reviewer suggests something better/more thorough/common pattern etc.

[pp] (personal preference of the reviewer)

This shows own opinion on style/unification etc. Might influence the author to apply some changes, but does not provide any benefits (it's not for optimization/better interfaces etc.)

[q] (question)

Reviewer would like to get some explanation on topic.


Author fixed/changed based on the comment.


Author declines the request. It should be first discussed with reviewer and explained in comment.


To whoever came up with this convention 😅

If you know let me know, so I can credit & thank them! 🙏

Happy and safe coding ✌️
