Answering Prompts

When a run enters waiting_answer, supply input with run.answer():

await run.answer({"approved": True})

An unvalidated answer is the node's to judge

ctx.ask(question) with no options hands run.answer()'s value straight to the body, unvalidated: nothing outside the node can judge a free-form answer, so the node raises on one it does not accept.

@workflow
async def resolve(ctx: WorkflowCtx, ticket: dict) -> str:
    decision = await ctx.ask(f"approve {ticket['id']}?")
    if decision not in ("yes", "no"):
        raise ValueError(f"approval expects 'yes' or 'no', got {decision!r}")
    return "approved" if decision == "yes" else "declined"

await run.answer("yes")   # decision == "yes", the node continues
await run.answer(12345)   # no error here  -  the node's own check raises instead

An ask that names options gets this refusal for free instead: see Workflows.
