+name: Edit already passed
+description: |
+  Reports whether this run comes from a pull request title or body edit on a
+  head commit whose previous run of the same workflow passed. Such an edit
+  cannot change the result, so callers skip their checks and the skipped
+  required checks still pass. A base change, a first run, or a previous run
+  that failed, was cancelled or is unfinished returns false and runs them again.
+  The calling job needs `actions: read`.
