Does it still need OS_BOTIFY_TOKEN to make a comment or would a github token do it?

[roryabraham]

I think just GITHUB_TOKEN would do it

[roryabraham]

Changing it would also have the side-effect of the comment not being left by OSBotify, but that's nbd if you think there's a reason to use only the GITHUB_TOKEN instead.

[AndrewGable]

Which is "more secure" or "more secret"?

[roryabraham]

I think OS_BOTIFY_TOKEN has some additional permissions so is therefore "more secret". I can update this PR to change the token used.

[luacmartins]

LGTM!

[roryabraham]

Okay, beginning testing now

[AndrewGable]

One reminder for the test steps, I think your main you branch or fork off of has to be up to date to have this updated workflow run

[OSBotify]

✋ This PR was not deployed to staging yet because QA is ongoing. It will be automatically deployed to staging after the next production release.

[AndrewGable]

So if we see this fail on contributor fork's, I think they will have to merge main in

Step 2 (regression test) passed: #4380

[roryabraham]

Nice, step 3 passed: #4381
