Open-source traffic-light prompt for AI coding agents to curb endless token use

Karl's AI Watts (@aiwarts) on X shares an open-source prompt that makes agents end each reply with a green, yellow, or red status line.

Green means original goals remain, yellow means a follow-up plan is ready for review, and red means leftover items are archived. The author says the system stopped Claude Code and Codex from endlessly suggesting optimizations and wasting token quota. The claim comes from the author's post; no independent test of the results was reported.
