• I'd be willing to implement this feature (contributing guide)

Describe the user story
The communication with Atlantis is very spamming. On a Pull Requests It results into a lot of comments which generates a lot of notifications of assigned reviewer. Especially, if the first try wont work, it would result into more unnecessary comments.

Describe the solution you'd like
Like #2818, Atlantis should own only comment if possible. The communication with Atlantis should be done via checkboxes.

Describe the drawbacks of your solution
Larger plans/outputs does not fit into one comments, consider to attach them as file attachment.

Describe alternatives you've considered
Use the check run API to publish the outputs (https://docs.github.com/en/rest/guides/using-the-rest-api-to-interact-with-checks?apiVersion=2022-11-28)

We'd like to implement the checks api which would remove the need for a github comment

• Option to use GitHub App's "Checks API" instead of PR comments #936

I think having it post a comment is reasonable if it can support updating the same comment.
IMO the spam problem is due to each push creating and posting new plans. I mean if they were not applied why do I care about them? the current plan is what's important.

@shaul75 The GH Check API is designed for that and can store the plan / apply for each commit separetly. There is no need for an comment.
