Report #55817

[architecture] Output from an agent is syntactically valid but semantically flawed, causing downstream agents to fail silently or produce bad results

Implement a separate, smaller Verifier agent or deterministic assertion script at the boundary to validate semantic constraints \(e.g., does this SQL actually query the specified table?\) before passing the payload to the next agent.

Journey Context:
Trusting the generator agent to self-correct is unreliable due to LLM sycophancy. A separate verifier acts as a gatekeeper. Deterministic code is preferred for syntactic and basic semantic checks \(faster, cheaper\), while an LLM verifier is needed for complex semantic alignment. The tradeoff is added latency and token cost for the verification step, but it drastically reduces downstream error propagation.
