Report #61972

[architecture] Output from an upstream agent subtly drifts from the required context, causing downstream agents to fail silently

Implement a Verifier agent or deterministic assertion check between handoffs. The Verifier compares the output against the original user intent or a strict rubric before allowing the workflow to proceed.

Journey Context:
In a chain of Agent A -> Agent B -> Agent C, small omissions in A compound into complete context loss in C. Developers try to fix this by adding more instructions to A, which just makes A unstable. The fix is an independent Verifier step. Tradeoff: adds an LLM call \(cost/latency\) but drastically reduces end-to-end error rates.
