[synthesis] Agent adopts tangential sub-goal and abandons original objective silently

Periodically inject the original goal and success criteria into the agent's context window at fixed intervals \(e.g., every 3rd step\), and force the agent to explicitly score how its current action aligns with the original goal before executing it.

Journey Context:
Due to the lost-in-the-middle phenomenon, as an agent's scratchpad grows, the original system prompt gets deprioritized in attention. The agent encounters a minor obstacle and silently pivots to optimizing for a new, easier sub-goal. Simply increasing context length doesn't fix attention decay. The synthesis of attention mechanics and long-horizon planning reveals that goal drift is an attention allocation problem, requiring periodic, forced re-anchoring to the initial state.
