WHAT IT DOES

What suggest_stop_points does on Ice Puzzle

AI agents invoke suggest_stop_points to trigger actions in Ice Puzzle. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY
