Let’s go extra meta today.
Please spend 20 minutes tidying up your PRs/issues/tickets/whatever.
If something is irrelevant, close or delete it.
If it something is old but might still be relevant, see if you can move it toward completion (or deletion). Try this: “This issue is quite old. I’m going to delete this early next week unless someone objects. That okay with you @whoever?”
If something is new and relevant, but not actionable, see if you can add or track down the information required to make it actionable.
I recommend working from oldest to newest.
As always, remember that the point isn’t to clean up all the things, it’s to spend 20 minutes chipping away at them.
