Call Agent2Agent agents from an ilmek graph — every round-trip journaled, so a pause/resume never re-sends a message the remote agent already acted on. Zero dependencies; the HTTP transport rides the global fetch.

npm install @ilmek/core @ilmek/a2a

import { A2aAgent, HttpA2aTransport } from "@ilmek/a2a";

const desk = await A2aAgent.connect(new HttpA2aTransport("https://desk.example.com"), { name: "desk" });
const r = await desk.send(ctx, "Where is ORD-42?");                       // once across resumes
if (r.needsInput) await desk.send(ctx, "Approve", { taskId: r.taskId, key: "answer" });

A remote agent's human-in-the-loop pause arrives as an input-required task with the open questions in statusText / statusData; the node decides whether to answer itself, ask its own human (ctx.interrupt), or give up. a2aNodes({ desk }) adds an a2a_call node type for stored graph specs.
