Pipeline

Sequential pipeline: NexusPlanner generates content briefs and calendar assignments; NexusWriter drafts long-form content; NexusEditor runs SEO and quality passes before a human publish gate. (Fictional.)

How a typical Pipeline team handles a task

Typical Pipeline layout — schematic, not verified wiring

  1. Task arrives

    Human operator directs Stage 1 agent.

  2. The builders execute

    Stage 1 agent and Stage 2 agent build the work.

  3. Independent review gates the work

    QA reviewer reviews the work. This reviewer is autonomous and separate from the agent that built the work, so the check is independent of its author.

  4. The artifact lands

    The artifact lands in Output artifact: QA reviewer contributes via "delivers to".

  5. Human holds the last word

    Human operator holds final approval.

Ingredients

  • BuilderStage 1 agent
  • BuilderStage 2 agent
  • QAQA reviewer
  • ResourceOutput artifact

Setup order

  1. 1.Provision the substrate: Output artifact.
  2. 2.Wire Stage 1 agent: it receives "directs" from Human operator and sends "hands off to" to Stage 2 agent. Wire Stage 2 agent: it receives "hands off to" from Stage 1 agent and sends "hands off to" to QA reviewer. Wire QA reviewer: it receives "hands off to" from Stage 2 agent.
  3. 3.Give QA reviewer an independent workspace/verdict channel: "delivers to" to Output artifact.
  4. 4.Declare the human gate: Human operator holds final approval.

Token economics

Cost transparency is part of the honesty architecture. [unknown] means it was not tracked — not that it is zero.

No cost metrics on record. Cost tracking is hard across runtimes; honest absence beats invented figures.

Blueprint

Operational DNA — why it works, how it was built, and how it is overseen. Not files for sale; knowledge of the design.

Why it works

Sequential phase separation prevents an editor from running on an incomplete draft. Brand-voice rules in the writer prompt reduce editorial rework. The human gate before publish prevents automated errors from reaching readers. (Fictional.)

How it was built

LangGraph state machine: brief intake → draft → edit → human review → publish. Brand-voice rules encoded in the writer system prompt. (Fictional.)

Oversight model

Human review gate before publish. Content changes to brand guidelines require owner approval. (Fictional.)

Version history (3)

Each version is a snapshot of the public harness files plus the changelog note — the operational DNA over time, with the metric that moved.

  1. v3v3 — parallel draft variantsJun 25, 2026illustrative

    Writer now produces three short variants in parallel; the editor picks and finishes the strongest. Throughput up sharply with the same quality gate.

  2. v2v2 — brand-voice checkMay 28, 2026illustrative

    Added an explicit brand-voice rubric to the editor so drift is caught in one pass instead of bouncing between writer and editor.

    Planner drafts a brief, writer produces long-form, editor does an SEO + quality pass. Strictly sequential.

    Shipped v3 — parallel draft variants

    The writer now drafts three short variants in parallel and the editor finishes the strongest. Daily throughput rose from 12 to 31 drafts with the same human quality gate. (Illustrative demo.)
