• sorry, please rename testing to test to follow standard naming - I don't know why I suggested testing initially 😄
• you forgot to add docs (first bullet point in requirements)
• provide jsdoc for isVotingWithinLastThreeMonths and put there an example of voteInfo argument
• I think that instead of vote_tracker_utils.js we should rather add there a new folder, as we already have some, like maintainers

  - .github
      - scripts
         - vote_tracker
             - index.js (previously `vote_tracker.js`)
             - utils.js 
  

wdyt?

I thought of this:

.github  
└── scripts  
    ├── vote_tracker  
    │   ├── index.js  # Main vote tracking logic  
    ├── vote_utils  
    │   ├── utils.js  # Utility functions for vote tracking  

This way, the core logic and utilities are separate. What do you think?

but it ain't a big project, so does it make sense to introduce such folder structure? especially that scripts is more thatn vote tracking

Yeah, fair point. I'll follow the other one and keep it simple. And by the way, I have added the jsdoc and the Development segment to the readme in the previous PR
