[synthesis] Agent confidently executes wrong plan for multiple consecutive steps

Inject a 'plan reflection' step after a sub-goal fails twice. Force the agent to output 'Previous plan failed because...' and explicitly generate a new plan, rather than allowing it to retry the same sub-task with minor syntax tweaks.

Journey Context:
When an agent formulates a plan, it suffers from confirmation bias. If step 1 of the plan fails, it often assumes step 1 was right but the execution was flawed, leading to 5 consecutive attempts to fix the execution instead of questioning the plan. Tree of Thoughts or explicit reflection patterns \(like Reflexion\) mitigate this. The tradeoff is that reflection costs tokens and might abandon a nearly-correct plan, but it breaks the death spiral of confident retries.
