Defense in depth approach, would this work to help as a layer?

- Wrap user input in strong markers like <user-input-do-not-trust />

- Have the agent compute what it will perform as structured output.

- Have another agent evaluate the structured output against the intent of the code.

- Determine if it aligns or deviates from the intended workflow. Execute or deny gate from here.
