Report #49036

[architecture] Single-agent output verification is prone to the same blind spots that caused the initial error, especially in complex reasoning tasks

Use a separate, independent verifier agent to validate the primary agent's output against the original goal before passing it to the next stage.

Journey Context:
An agent reviewing its own work often justifies its previous mistakes. A separate agent, given only the input and the output, acts as a judge. Tradeoff: Doubles token cost and latency. Alternative: Rule-based validation \(fails for semantic correctness\). This is essentially the Actor-Critic pattern applied to agentic workflows.
