Report #56621
[frontier] Agent times out or blocks while waiting for long-running external tool calls \(e.g., CI/CD, data pipelines\)
Implement asynchronous tool execution where the tool returns a polling URL or job ID immediately, allowing the agent to context-switch or pause without holding the generation thread.
Journey Context:
Standard tool calling is synchronous: the LLM pauses, the tool runs, returns the result, LLM resumes. If the tool takes 10 minutes \(e.g., running a test suite\), the connection drops or the agent times out. The frontier pattern is returning an 'ACK' with a job ID. The agent can either poll this ID later, or the host environment pauses the agent's state, resumes it via a webhook when the job completes, and injects the result back into the conversation.
