[frontier] Single-pass agent producing hallucinated outputs without verification or no mechanism for agent to critique its own plan

Implement nested chat patterns where a 'critic' agent reviews the 'actor' agent's output in a separate conversation turn before finalizing, using AutoGen's nested chat or similar patterns.

Journey Context:
Naive agents generate a response and return it immediately. In production, this often produces subtle hallucinations or logic errors that a simple self-check \('Are you sure?'\) fails to catch because the same model has the same biases. The robust pattern is nested reflection: the primary agent \(actor\) produces a draft, then a secondary agent \(critic\) with a different system prompt \(focused on finding security holes or logic gaps\) reviews it in isolation. The critic's feedback is then fed back to the actor for revision. AutoGen formalizes this as 'nested chats' where inner dialogues don't pollute the outer conversation history. This separates generation from verification, preventing the 'echo chamber' of single-model reflection and catching errors that would otherwise reach users.
