[synthesis] Context poisoning cascades across steps via accumulated minor hallucinations in scratchpads

Implement periodic 'reality checks' where the agent must re-verify key premises from the environment \(not its own history\) before executing critical steps. Use a separate 'verifier' model or tool that only checks the alignment between the scratchpad and actual system state.

Journey Context:
A common mistake is trying to fix this by increasing model intelligence or using longer contexts. However, larger contexts just give more room for the fabricated history to reinforce itself. Another failed approach is strict JSON-only outputs, which just hides the reasoning rather than fixing it. The synthesis of cognitive psychology \(belief perseverance\) and LLM context conditioning shows that the agent's own generated text is the most toxic context. Decoupling the planning context from the verification context is the only reliable circuit breaker.
