It's good practice to cancel the cog when unloading. I'm believe it's done here too (not too sure), but it can lead to some problems because a task isn't automatically cancelled when the cog is unloaded.

async def cog_unload(self):
   self.refresh_repos.cancel()

It wasn't done, I had no idea that was best practice but I have implemented it now.

Thx for addressing the reviews earlier, these are just some minor ones

So far, it looks good to me, I'll review once more after this change

So far liking the general implementation. These comments are more about code style. I previously began a review but it looks like GitHub ate my comments so I might have more to add later.

this is shaping up nicely, I don't have any more changes:)
