repo property
Repo is what to work on, as owner/name in the caller's own org. The engine resolves the clone URL and the push credential from the org itself, so this says WHICH repository and never how to reach it.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? repo;
