Sounds like you misunderstood. They didn't say they are merging PRs after a few seconds. Just that the difference between a good one and a bad is often obvious after a few seconds. Edit: typos
replyExactly, every PR starts with:
reply1. What’s the goal of this PR and how does it further our project’s goals?
2. Is this vaguely the correct implementation?
Evaluating those two takes a few seconds. Beyond that, yes it takes a while to review and merge even a few line diff.
I'm not sure there are many ways to interpret "I know whether I want to merge a PR within a few seconds".
replyYet I also agree with GP.
reply"*WANT* to close or *WANT* to merge". Not WILL close or WILL merge.
replyYou look at the PR and you know just by looking at it for a few seconds if it looks off or not.
Looks off -> "Want to close"
Write a polite response and close the issue.
Doesn't look off -> "Want to merge"
If we want to merge it, then of course you look at it more closely. Or label it and move on with the triage.
