Report #42629

[architecture] Errors compound exponentially down a multi-agent chain because each agent blindly trusts the previous agent's output

Insert a 'Critic' or 'Verifier' agent between the 'Generator' and the 'Executor' agents. The Critic evaluates the output against the original goal and a rubric, returning a PASS/FAIL before the Executor acts.

Journey Context:
In a chain A -> B -> C, if A makes a small error, B might misinterpret it and make a larger error, causing C to fail catastrophically. A critic agent breaks this compounding by adding an explicit validation step. The tradeoff is increased latency and token cost, but it drastically reduces cascading failures.
