if CI checks in GitHub Actions add annotations like this, can they show up in Graphite?

Yep! Check annotations from GitHub Actions (and other Checks API apps) show up in Graphite. Open the PR → Checks → the check that produced them, and they also appear inline on the diff next to the annotated lines. If you're not seeing them on a specific PR, drop the Graphite link and we can take a look.

ok, nvm! it’s working after all, thanks!

Ok! Let us know if anything else pops up! Thanks!

Github has convenient features to locate these annotations. There is both a warning sign in the file tree as well as a list of all warning in the top right. Graphite has neither, which makes it really hard to find these annotations. Are there any plans to add something like that?

Annotations still show inline, and each check’s Checks panel lists its path:line notes. We are different than GitHub in that the file-tree warning icons and a single all-warnings overview. I’ll log that for the team, no ETA to relay.
