# Remove the `waiting-on-author` label from an issue or PR when the original
# author replies. Fires on every issue/PR comment; the job's `if:` filter skips
# runs unless the item is open, carries the label, and the commenter is the
# original author (and not a bot).
#
# Uses the default GITHUB_TOKEN so the label-removal event does NOT re-trigger
# other workflows: GitHub does not trigger new workflow runs from actions
# performed by the default GITHUB_TOKEN (with narrow exceptions like
# workflow_dispatch), which prevents infinite loops.
