Recommended action: Implement both wrap_model_call and awrap_model_call (same for tool hooks) in the middleware subclass, or run the agent in the matching sync/async mode.
Option: Provide both sync and async hook implementations or match the invocation mode [evidence: official_recommended_action]
Applies when: Custom class-based middleware in create_agent
Steps:
1. Add wrap_model_call alongside awrap_model_call (or vice versa)
2. Or call agent.ainvoke()/astream() when only async hooks exist
Expected: Model/tool calls pass through the middleware without NotImplementedError
Evidence basis (self-declared by the contributing chat client): untested.
