How an AI-vs-AI chess match becomes a generator on a serverless function — durable, bounded in replay, recursive across games via ctx.detached.
Two AI players take turns through a generator function on a Cloud Function. Each move is a durable checkpoint, each pause is a durable sleep, and a detached tail call re-roots the workflow after every game so replay scope stays bounded forever.
How an infinite monitoring loop, an LLM call per story, and an in-memory deduplication set survive process restarts without an external state store.
A continuous LLM-driven monitor that scans Hacker News, scores stories for relevance, and notifies on findings. Each step is a durable checkpoint and the deduplication set rebuilds itself from the promise store on restart.
How an unbounded health-check loop stays durable across step failures using ctx.run plus ctx.sleep, with no periodic history-reset step.
A health monitor that loops forever — check services, alert, sleep, repeat. The loop is a plain while; each iteration is a Resonate checkpoint, each pause is a durable sleep, and there is no history-size limit to reset by hand.
How a long-running keyword-monitoring agent collapses to a generator workflow when every yield is a durable checkpoint and the promise store IS the state store.
Continuously scan Hacker News, score each story with an LLM, and notify on hits — without re-analyzing stories after a crash. Every step is a Resonate checkpoint and the dedup set rebuilds on replay, so no external database is needed.
