Report #43534

[architecture] Low-confidence agent output propagates through chain causing compounding errors

Implement confidence scoring at each agent output and define explicit escalation thresholds — below threshold, route to a verifier agent or human rather than passing to the next agent in the chain

Journey Context:
In multi-agent pipelines, each agent's uncertainty compounds. If Agent A is 70% confident and Agent B is 70% confident in its interpretation of A's output, the chain confidence is ~49%. People commonly treat all agent outputs as equally reliable, or they add confidence scoring but never act on it. The key insight: confidence without an escalation trigger is theater. You need a concrete threshold \(e.g., confidence < 0.7\) that triggers an alternative path — a verifier agent, a retry with different parameters, or a human checkpoint. The tradeoff: aggressive thresholds increase latency and cost, but they prevent the compounding error cascade that destroys trust in the entire pipeline.
