+# Timeline Demo Workflow Action
+# Action metadata for the timeline_demo workflow definition.
+#
+# The workflow graph (tasks, transitions, variables) lives in the separate
+# workflow file referenced by `workflow_file`. This action YAML controls
+# action-level concerns: ref, label, parameter schema, output schema, tags,
+# and (in future) execution policies.
+#
+# Multiple actions can reference the same workflow file with different
+# parameter schemas or policy configurations.

+description: >
+  A comprehensive demo workflow that exercises every feature of the
+  Workflow Timeline DAG visualizer: parallel branches with different
+  durations, with_items fan-out, failure handling paths, publish
+  directives, retries, timeouts, and custom edge styling.
