[synthesis] Agent validates its own wrong assumption by reading back state it incorrectly created

Never let an agent verify its own writes through the same tool path it used to create them. After any state-modifying action, verify through an independent tool or path \(e.g., write via API, verify via direct file read; write to database, verify via separate query tool\). Add adversarial verification steps that specifically look for evidence contradicting the agent's assumption rather than confirming it.

Journey Context:
In ReAct-style loops, the agent acts then observes. But the observation is of a world the agent just modified. If the initial action was wrong \(wrong file, wrong key, wrong format\), the observation confirms the wrong state exists — it does not confirm the right state was achieved. The agent sees its own reflection and mistakes it for ground truth. This is epistemic closure: the agent's world model becomes self-consistent but disconnected from reality. The 'LLMs Cannot Self-Correct' paper demonstrated that LLMs without external feedback cannot escape wrong reasoning through self-reflection alone. The common wrong fix is adding 'double-check your work' to the prompt, which just makes the agent re-read its own output and confirm it. Another wrong fix is running the same verification step twice, which provides false redundancy. The right fix is structural separation between creation and verification paths, plus adversarial framing that forces the agent to seek disconfirmation.
