Kael's AI Watts open-sources a traffic light prompt to solve the issue of Agents running out of control and wasting token quotas

The author shares a progress prompt and hook under 300 characters that enables an Agent to output a three-state traffic light indicator (🟢🟡🔴) at the end of each turn, distinguishing between unfulfilled original requirements, achieved goals with potential for subsequent plans, and achieved goals for archival purposes only. The process pauses upon turning yellow or red, awaiting further instructions. The author uses it to solve the problem of Agents like Claude Code and Codex running endlessly due to suggestion lists, which wastes token quotas, applicable to sub-agents and various types of tasks as well.
