Report #99511

[synthesis] agent forgets mid-plan constraints because they fall out of the context window's attention hotspot

re-read the original constraints and a living checklist before every action; split long tasks into bounded sub-tasks with explicit handoffs

Journey Context:
Long-context models do not uniformly attend to long prompts; middle instructions fade first. Agents commonly front-load constraints, write a plan, then execute, and the middle items of that plan are the first to drop out. Re-prompting constraints each step costs tokens but is cheaper than recovery from a violated constraint. Hierarchical planning trades context length for coordination overhead and is the right call when the task exceeds roughly half the model's effective attention span.
