I went searching for an existing request for this feature and found this topic, which seems the most relevant to me after a quick read. I hope that’s alright.
I’m also interested in exposing the
description field included in createDeployment and createDeploymentStatus API calls on the Deployment Dashboard. Particularly, I’d like to include GitHub-flavored Markdown in those fields to allow that the Deployments Dashboard can use text, links, and images to provide additional context to contributors about the Deployment’s behavior. Today’s functionality allows me to provide a URL to an external dashboard including that sort of information: displaying this sort of information on the Deployments Dashboard would allow contributors to discover this information without leaving GitHub.
