📄 Description

Description

Adds examples/async-subagent-server/ which is a complete end-to-end example showing how to self-host an async subagent on your own infrastructure using the Agent Protocol.

Changes

  • server.ts: a Hono server implementing the Agent Protocol endpoints (POST /threads, POST
    /threads/:id/runs, GET .../runs/:id, GET .../state, POST .../cancel) backed by Postgres. Swap in any createDeepAgent agent with no changes to the HTTP layer.
  • supervisor.ts: an interactive REPL demonstrating all five async subagent operations (launch, check,
    update, cancel, list) against the server.
  • docker-compose.yml: one-command local setup (server + Postgres).

Why this matters: The existing async subagent examples require LangGraph Platform. This shows that the same AsyncSubAgent config works against any server that speaks Agent Protocol. This is useful for teams that want to self-host or run on custom infra.
