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, hitl, publish_interrupts
ask(question, policy)— a thin wrapper overinterrupt(); the policy rides along inside the interrupt value. A plaininterrupt(value)also works, with the default policy.@hitl(policy)— on a tool function, under@tool. Callsask()with{tool, args}before the tool runs.mode="async"makes the decorator the publisher: it announces and returns pending without parking the thread.publish_interrupts(result, thread_id, announce)— aftergraph.invoke(). Readsresult["__interrupt__"]and hands one envelope per question to the announcers. Understandsask(), bareinterrupt(), andHumanInTheLoopMiddlewarebatches.
Requires langgraph >= 1.2. One interrupt() per node — two interrupting tools in one
ToolNode share an id on 1.2.x (langgraph #6626); use the middleware, which batches.
