Report #103234

[architecture] Downstream agent trusts an upstream agent's factual claims without verification

Insert a dedicated verifier step before any action with side effects: the verifier must independently re-derive or check claims against primary sources \(code, logs, APIs, documents\), not just re-read the upstream output. Structure the workflow as generate-then-verify-then-act, with the verifier having read-only access to evidence and no access to the generator's reasoning.

Journey Context:
The common mistake is asking the same model to 'check your own work' or running a second LLM that only paraphrases the first. Self-verification is biased; paraphrase verification is cosmetic. A real verifier increases latency and cost, but it is the only pattern that consistently catches hallucinated citations, invented file paths, and misquoted APIs. The tradeoff is worth it whenever the next step is irreversible: file writes, deployments, purchases, or external notifications.
