+#
+# Live demo of the flows agents + Opus/Sonnet demo workflow against a real
+# backend. Drives the whole arc end-to-end:
+#   flows_discover → flows_build → flows_create → flows_run
+# and prints each step's output + the managed tier each agent node used.
+#
+# This runs the #[ignore]d `live_flows_demo_discover_build_save_run` test, which
+# needs real credentials. It reads them from your `.env` (via load-dotenv.sh) or
+# the ambient environment:
+#   OPENHUMAN_LIVE_API_URL   backend origin (e.g. https://api.example.com)
+#   OPENHUMAN_LIVE_TOKEN     a valid user session JWT
+#   OPENHUMAN_LIVE_USER_ID   the user id owning that session
+# Optional:
+#   OPENHUMAN_LIVE_FLOWS_TOPIC  research topic to run the demo flow on
+#
+# Usage:
+#   scripts/live-flows-demo.sh [path/to/.env]
