[synthesis] Agent builds reasoning on stale or incorrect tool outputs because it assumes tool responses are infallible ground truth

Implement a 'trust but verify' pattern: for critical decisions, require the agent to cross-reference tool outputs with a second independent source or a known baseline before proceeding.

Journey Context:
Agents are trained to use tools to ground their reasoning. This creates a bias where tool output is treated as 100% accurate. In real systems, APIs fail, caches are stale, and databases are outdated. By forcing cross-referencing for high-stakes actions, you shift the agent from 'tool executor' to 'tool evaluator,' preventing cascading failures from bad data.
