step13_middleware

Overview ¶

This sample shows how to write custom agent middleware. A middleware wraps the agent's run function, so it can inspect or modify the incoming messages and options and observe (or rewrite) the streamed response updates.

It layers two agent-run middlewares that filter text on the way in and on the way out, mirroring the .NET "Agent_Step11_Middleware" sample:

• a wording guardrail that redacts blocked keywords, and
• a PII filter that redacts emails and phone numbers.
