 Use `skills=skill_sources or None`, not an empty list, so agents without a
 `skills/` directory still build cleanly.

+## Invocation Budget
+
+Generated agents should use the same recursion budget as agent-builder:
+
+```python
+state = await graph.ainvoke(
+    {"messages": [{"role": "user", "content": prompt}]},
+    config={"recursion_limit": 500},
+)
+```
+
+For streaming/event loops, pass the same config to `graph.astream_events(...)`.
+This prevents normal multi-step skill/subagent workflows from failing at the
+default LangGraph recursion cap.
