Ellipsis automatically creates and maintains a pull request summary. This summary is appended to the PR description; it doesn’t overwrite the existing description. The summary is updated as you add new commits to the PR.
You can customize the summary by providing a custom prompt in the UI.
You can have Ellipsis automatically write the title of the PR by creating a PR with the title ... (ellipsis). The title will be updated as you add new commits to the PR.
