- Tokens remaining: ${remainingTokens(goal) ?? "unbounded"}

Avoid repeating work that is already done. Choose the next concrete action toward the objective. Before deciding it is achieved, audit the actual current state against every explicit requirement and concrete evidence. Only call update_goal with status "complete" when no required work remains. If blocked, explain the blocker and wait for input.`;

The system has marked the goal as budget_limited, so do not start new substantive work for this goal. Wrap up this turn soon: summarize useful progress, identify remaining work or blockers, and leave the user with a clear next step. Do not call update_goal unless the goal is actually complete.`;
