Chapter 4.5 -- Agent Middleware

Companion code for Generative AI in .NET, Chapter 4 sections 4.5.1 -- 4.5.4 ("Agent Run Middleware" and "Building the Middleware Pipeline").

Wraps an agent in a small agent run middleware that logs the start and end of every RunAsync call. The same Use(...) builder pattern works for input filtering, rate limiting, output redaction, etc.
