Starting from while true + cat task.md, building up through stop hooks, file-based state persistence, and cross-model worker-reviewer separation. Three practical examples — coding migration, prompt refinement, and test coverage expansion — plus analysis of the open-source ecosystem and Korea's Ralphathon.
RLHF, ReAct, Reflexion, LangGraph/AutoGen, Context Rot, Ralph Loop. Six generations of agent loop architecture — what each solved, what each broke, and why a Bash while-loop turned out to be the answer.
