Module guards 

G — Guard composition.

Combine output guards with +: every guard must pass (G::pii() + G::length(1, 2000)).

Wiring

A GuardComposite attached via AgentBuilder::guard is installed on the compiled LlmTextAgent as an after_model middleware layer (see GuardComposite::into_middleware). Every model response is checked against all guards; if any guard rejects the output the agent run fails with an AgentError enumerating the violations, vetoing the response.

Structs

G

The G namespace — static factory methods for guards.

GuardComposite

A composite of guards — all must pass for output to be accepted.

GuardRule

A guard that validates agent output.
