# News Desk

> Reporter → editor → headline writer → publisher. A clean editorial pipeline that newcomers can follow at a glance.

A four-agent editorial pipeline that mirrors a real newsroom handoff. A reporter drafts the story, an editor tightens it, a headline writer produces three options, and a publisher selects one and assembles the final package.

## What it demonstrates

* A four-node sequential pipeline with role-specialized agents
* Each agent building on all accumulated `working.*` context from prior nodes
* Output formatting conventions: the publisher labels `Headline:`, `Lede:`, and `Body:`
* A real-world analogy that maps directly onto the SirenSpec node/edge model

## Run it

```bash theme={null}
sirenspec run docs/cookbook/news-desk/workflow.yaml
# Try a different story:
sirenspec run docs/cookbook/news-desk/workflow.yaml \
  --input "A city council vote approved a ban on single-use plastics starting next year."
```

## Workflow

```yaml docs/cookbook/news-desk/workflow.yaml theme={null}
version: "0.1"

agents:
  reporter:
    model: "openai:gpt-4o-mini"
    system: |
      You are a news reporter. Write a raw 150-word first draft covering
      who, what, when, where, and why. Focus on facts, not polish.

  editor:
    model: "anthropic:claude-haiku-4-5-20251001"
    system: |
      You are a newspaper editor. Rewrite the draft for clarity,
      cut it to under 100 words. Preserve all facts. No new information.

  headline_writer:
    model: "openai:gpt-4o-mini"
    system: |
      Write exactly three headline options. Each: punchy, accurate, under 10 words.
      Return as a numbered list, nothing else.

  publisher:
    model: "anthropic:claude-haiku-4-5-20251001"
    system: |
      Choose the strongest headline and write the final package:
      Headline: [chosen headline]
      Lede: [one-sentence hook]
      Body: [edited article]

nodes:
  report:
    agent: reporter
    writes: working.draft
  edit:
    agent: editor
    writes: working.edited
  headline:
    agent: headline_writer
    writes: working.headlines
  publish:
    agent: publisher
    writes: output.article

edges:
  - from: report
    to: edit
  - from: edit
    to: headline
  - from: headline
    to: publish

guardrails:
  - injection
  - length
```
