Report #79440

[architecture] Complex multi-step reasoning fails silently because an intermediate agent's output drifts off-task without triggering a validation error

Insert a lightweight 'Verifier' agent between the worker and the next step. The Verifier evaluates the output against the original sub-task instructions using a strict rubric, returning a pass/fail before the handoff.

Journey Context:
Just passing data along assumes the worker succeeded. Testing via traditional assertions is hard for natural language. LLM-as-a-judge provides semantic validation. The tradeoff is that this doubles the LLM calls and latency for the step. An alternative is using smaller, specialized classifier models for verification to reduce latency and cost.
