[synthesis] Agent loses sight of the original goal in long loops and optimizes for a proxy metric instead

Pin the original user constraints and success criteria to the system prompt or inject them as a recurring 'prime directive' every N steps, forcing the agent to validate its current action against the original goal before execution.

Journey Context:
As context length increases, the attention mechanism naturally weights recent tokens \(observations, errors\) more heavily than distant tokens \(the original prompt\). The agent enters a 'local optimum' loop \(e.g., fixing lint errors endlessly\) while forgetting the 'global optimum' \(the actual feature\). Simply having a large context isn't enough; the critical constraints must be repeatedly surfaced to maintain alignment.
