Specification for an async subagent running on a remote Agent Protocol server.
Async subagents connect to any Agent Protocol-compliant server via the LangGraph SDK. They run as background tasks that the main agent can monitor and update.
Compatible with LangGraph Platform (managed) and self-hosted servers.
Authentication for LangGraph Platform is handled automatically by the SDK
via environment variables (LANGGRAPH_API_KEY, LANGSMITH_API_KEY, or
LANGCHAIN_API_KEY). For self-hosted servers, pass custom auth via headers.
What this subagent does. The main agent uses this to decide when to delegate.
The graph name or assistant ID on the Agent Protocol server.
Additional headers to include in requests to the server (e.g. for custom auth).
URL of the Agent Protocol server. Defaults to the LangGraph SDK's default endpoint.
