What Is an Agent Pipeline With a Review and a Person?

Write the smallest team shape that holds up in a page: steps in order, a review that fails a step and runs the step that owns the fix again with the findings, and a person who decides at the end. That is an agent pipeline with a review and a person. Without the review it’s a queue; without the person nobody owns what ships. The neighbour term is a software factory, the same shape at a larger scope.

In Obversa

pipeline() runs the steps in order, and the review is a step in it:

examples/feature-team.ts (excerpt)

export const featureDelivery = pipeline(
  'feature-delivery',
  [
    { name: 'analyse', job: analyse },
    { name: 'implement', job: implement },
    { name: 'test', job: testStage },
    { name: 'review', job: review, acceptsKickbackTo: ['implement'] },
    { name: 'approve', job: approve },
  ],
  { maxKickbacks: 2 },
);

review is a panel of three that passes on two and names implement as its target, so a failing review runs the implementer again with the findings. The review stage declares that target in acceptsKickbackTo. approve is a person’s question. maxKickbacks caps how often the review can do that; when the budget runs out, the run fails with the last findings instead of looping. The excerpt comes from a scripted test of the workflow shape. Feature delivery uses Claude, Codex and Gemini for the work.

The three parts

Part	In the file
Steps in order	`pipeline` with five named steps.
A review that runs a step again	`reviewPanel` with three reviewers, `pass: 2`, `target: 'implement'`.
A person at the end	`approval` with a question. The test supplies an answer; in a real team the answer arrives through the callbacks client, and the run pauses until it does.

Next steps

Feature delivery: the same shape on real engines.
A person decides: how the answer comes back to a paused run.
