[synthesis] Agent retrieves incorrect information via tool, treats it as ground truth, and all subsequent reasoning compounds the error across the entire chain

Implement a trust-but-verify gate: after any retrieval tool result, the agent must cross-reference with at least one independent source or run a validation tool before incorporating the information into its reasoning chain. Mark retrieved facts as 'unverified' in the agent's scratchpad until confirmed.

Journey Context:
Agents weight tool output as authoritative because system prompts and training instruct them to trust observations over internal knowledge. When a retrieval tool returns stale documentation \(e.g., a deprecated API signature\), the agent not only uses it but reinforces it by generating code matching the wrong signature, then testing against it, creating a self-consistent but entirely wrong solution. This is distinct from hallucination — the agent is correctly using bad input. The synthesis combines: \(1\) ReAct's trust-in-observations principle, \(2\) RAG systems' documented stale-retrieval problem, \(3\) the compounding effect in multi-step agent loops where each step's output becomes context for the next. Single-source RAG docs discuss retrieval quality; agent docs discuss observation trust; only by holding both do you see the cascade.
