> Okay very clear! I was saying that because your post example is just a kind of basic "tool use" example which is already implemented by MCP/OpenAI tool use, but obviously I guess your code can be suited to more complex scenarios

That's mostly just because I found that to be the easiest way to use any existing AI API to work. There are things like vercel's AI SDK which internally runs the agentic loop in generateText, but then there is no way to checkpoint that.

> I was just wondering, how does it work? I was more expecting a generator with a `yield` statement to run "long-running tasks" in the background... otherwise is the node runtime keeping the thread running with the await? doesn't this "pile up"?

When you `awaitEvent` or `sleepUntil`/`sleepFor` it sets a wake point or sets a re-schedule on the database. Then it raises `SuspendTask` and ends the execution of the task temporarily until it's rescheduled.

As for your IOT case: yes, you should be able to do that.
