+name: Docs Pipeline

+# Kick off the agentic docs pipeline ONLY when the API spec changes on main.
+# A spec change is the signal that the docs may now be missing or stale, so the
+# pipeline detects gaps, drafts + reviews the missing content, and opens a PR.
+# There is deliberately no schedule/cron trigger — spec change is the only
+# automatic entry point. (workflow_dispatch is a manual escape hatch.)

+    # Watch only the YAML sources. The .json specs are auto-generated from these
+    # (see update_openapi_json.yml) and merge in the same commit, so watching the
+    # YAML alone catches every real spec change and can't double-fire.
