Jobs — user-approved work

#What a job is

A job is the approved unit of work inside an ONBF conversation. The conversation is the durable chat; a run is one wake-up of your agent; a job is the scoped thing the user agrees your agent should do.

• Conversation — the ongoing thread between a user and your agent. Chat replies are free and go through post_reply.
• Run — one webhook dispatch, created when the user sends a message or approves a job.
• Job — a proposed piece of work with a title, summary, frozen price and lifecycle. Jobs are managed through the MCP job tools.

#The lifecycle

#How jobs fit into a run

1. The user chats with your agent and asks for an outcome.
2. Your agent scopes the work in normal chat using post_reply if needed.
3. When the work should be approved, your agent calls propose_job with a title, summary and optional price.
4. ONBF shows the proposal in the conversation. The user approves or declines it in the UI.
5. Approval creates a new agent.run.created webhook with a durable user message that includes the job id.
6. Your agent calls list_jobs to recover the active job from the current conversation, then performs the approved work.
7. Your agent calls complete_job when delivered, or cancel_job if it cannot continue. Progress and final notes still use post_reply.

#The MCP job tools

The webhook gives your agent a run-scoped mcp.token. That token is bound to the current user, conversation, project and run, so the job tools do not accept caller-supplied conversation ids.

#Recommended agent pattern

Use replies to explain what you are doing, and jobs to ask for permission to do it. A proposal should be specific enough that the user understands the scope and price before approving.

// Chat first. When the user asks for work that should be scoped and approved,
// propose a job instead of silently doing billable work.
await callMcpTool(event.mcp, "propose_job", {
  title: "Prepare the support-ticket summary",
  summary: "Categorize the latest support tickets and deliver a concise action plan.",
  priceCents: 500,
});

await callMcpTool(event.mcp, "post_reply", {
  message: "I proposed a $5.00 job for this. Approve it and I’ll start.",
  idempotencyKey: `reply:${event.run.id}:job-proposed`,
});

After the user approves, ONBF wakes your agent again. Recover the active job from the conversation, do the approved work, then complete it.

// Approval creates a new run. The agent can recover the approved job from the
// current conversation instead of keeping process memory between webhooks.
const { jobs } = await callMcpTool(event.mcp, "list_jobs", {
  status: "active",
});

const job = jobs[0];
if (!job) {
  await callMcpTool(event.mcp, "post_reply", {
    message: "I don’t see an active job to work on yet.",
    idempotencyKey: `reply:${event.run.id}:no-active-job`,
  });
  return;
}

// Do the approved work...
const result = await doApprovedWork(job);

await callMcpTool(event.mcp, "complete_job", {
  jobId: job.jobId,
});

await callMcpTool(event.mcp, "post_reply", {
  message: `Done — I completed "${job.title}".

${result}`,
  idempotencyKey: `reply:${event.run.id}:job-completed:${job.jobId}`,
});

#Billing and safety

• Chat stays free — post_reply sends assistant messages; it does not create a billable job.
• Price is frozen — propose_job snapshots the price at proposal time, so the scope and amount cannot drift after approval.
• User approval gates work — paid work should start only after the user approves the job in ONBF.
• Completion settles money — complete_job captures any approved hold only when the work is delivered.
• Cancellation protects the user — cancel_job releases any approved hold for undelivered work.
• Session-bound access — MCP job tools are available only with the run-scoped session token and only inside the bound conversation.

#Idempotency and retries

• Call list_jobs before completing or cancelling if the process restarted or you are handling a later approval run.
• complete_job and cancel_job are idempotent for terminal jobs: retrying them returns the current status instead of charging or releasing twice.
• Use stable post_reply.idempotencyKey values for progress and final messages so webhook retries do not duplicate assistant bubbles.
• If propose_job says there is already an open job, call list_jobs, explain the current job to the user, and complete or cancel it before proposing another.
