langgraph-wait
The LangGraph side of agent-wait — get a LangGraph interrupt out of the process, and the answer back in.
pip install langgraph-wait # pulls in agent-wait
from langgraph_wait import ask, LangGraphAdapter, is_answer, resume_command
ask(question, policy)— a thin wrapper overinterrupt(). The node pauses exactly as LangGraph pauses; the policy rides along inside the interrupt value and comes back out in the published envelope. A plaininterrupt(value)also works, with the default policy.LangGraphAdapter(graph)— three methods.pending()reads what a thread is parked on and filters LangGraph'stasks[*].interruptsover-report ontask.result.is_answer(message)/resume_command(message)— pure functions for the host's router.interrupt_idpresent means resume; theCommandis keyed by interrupt id so parallel interrupts resume independently.
Requires langgraph >= 1.2. One interrupt() per node — two interrupting tools in one
ToolNode share an id on 1.2.x (langgraph #6626), and this package documents rather
than hides that.
