subagents: cannot start workflows

[kamranayub]

Describe the bug

I was trying to build off the experimental/gadgets-subagents and examples/workflows to combine them. I basically wanted a sub agent to kick off and own a workflow.

I had an AgentWorkflow named FlightSearchWorkflow and a TripPlannerAgent parent agent.

I defined a FlightSearchAgent and had code like this in a method:

async runFlightSearch(task: string) {
  console.log("Running flight search workflow...");
  const instanceId = await this.runWorkflow("FLIGHT_SEARCH_WORKFLOW", { task });
  console.log("Started flight search workflow with instanceId:", instanceId);

  // ...
}

It never got to the second log, instead it threw an error:

Could not detect Agent binding name from class name. Pass it explicitly via options.agentBinding

To Reproduce
Steps to reproduce the behavior:

1. Create and export an AgentWorkflow that does a step
2. Create an Agent
3. Create a subagent with a doSomething method that calls this.runWorkflow and export it
4. In the parent agent, call this.subAgent to get it
5. Invoke the doSomething method
6. See error

(Assuming all Wrangler setup is there)

Expected behavior

Subagents should be able to a workflow AgentFlow functionality the same way a top-level Agent does.

Version:
0.11.4

work in progress here, but I think this might a while to land (I'm going out of town for the next week, can get to it when I'm back)

You can try npm i https://pkg.pr.new/agents@1430 and see if it works for you? If it does I'll land and release this tomorrow

[threepointone]

did you try this?
