In examples/05_custom_agent.py lines 63-66, get_system_messages returns mcp.types.TextContent objects. _run_context passes these messages directly into AsyncOpenAI.chat.completions.create, which expects dictionaries with role/content. Supplying ContentBlock instances will raise OpenAI client validation/type errors before any inference runs, so the example crashes immediately. Construct system messages as OpenAI-style dicts (as in other OpenAI agents) instead of MCP content blocks.
