[synthesis] Agent becomes increasingly confident in a wrong conclusion across consecutive reasoning steps

Inject adversarial doubt checkpoints at fixed intervals. Every N steps, force the agent to argue against its current conclusion, enumerate what evidence would disprove it, and check whether any step's output was assumed rather than verified. Implement a 'devil's advocate' step as a mandatory control flow primitive.

Journey Context:
Sycophancy research shows LLMs agree with presented premises; chain-of-thought research shows step-by-step reasoning improves accuracy; but the spiral is the synthesis. In a multi-step agent loop, the agent's OWN previous outputs become the context it reads and reinforces. Step 1 produces a wrong assumption; step 2 reads step 1's output and treats it as established fact; step 3 reads steps 1-2 and builds further. Each step increases confidence because the agent sees its own consistent reasoning, never realizing the foundation was wrong. This is structurally identical to echo-chamber dynamics but within a single agent session. The common wrong fix is adding 'be careful' to the system prompt, which does nothing because the agent is already being careful—it's just being careful about the wrong thing. The right fix is an architectural control: mandatory adversarial checkpoints that break the self-reinforcement loop. The Reflexion pattern \(self-critique after action\) partially addresses this but only post-hoc; the key insight is that the checkpoint must happen DURING the chain, not after it.
