Journalism Agent

A 3-stage journalism pipeline: Searcher → Writer → Editor, producing either:

Final output

Workflows

Article Mode

User: "Write a 1000-word piece on the future of community libraries"

1. Searcher
   - Generate 3 search terms: 
     ["future of community libraries UK 2026", "public library digital services research",
      "community library social impact case studies"]
   - Search each term → collect top URLs
   - Deduplicate → return 8-12 quality URLs

2. Writer
   - Read top 4 URLs with web_fetch (prioritise gov.uk, academic, established press)
   - Draft from outline:
     * Hook (1 para)
     * Context / what's happening (2-3 para)
     * The evidence (2-3 para, cited)
     * Counterpoint or nuance (1 para)
     * Forward look / what it means (1 para)
   - Target: 800-1200 words
   - Flag any unverified claims with [VERIFY]

3. Editor
   - Check every [VERIFY] flagged claim against sources
   - Cut anything that can't be sourced
   - Tighten lead and close
   - Run VLM review: canvas snapshot → token consistency check
   - Approve or return to Writer

Newsletter Mode (mixed articles + listings)

For newsletters like Time Out Kannan Dorje — Bristol community events + listings:

1. Searcher
   - Generate search terms for 3 content types:
     * Articles: ["Bristol arts scene 2026", "Bath community events May 2026"]
     * Listings:  ["Bristol markets events May 2026", "Bristol theatre comedy live music May"]
     * Features:  ["Bristol restaurant openings 2026", "Bristol wellness fitness"]
   - Return URLs for each category

2. Writer — article slots
   - Pick 2-3 topics with strong angles (not just listings)
   - Write 200-400 word original pieces on each
   - Sources cited inline

3. Writer — listing/event slots
   - Curate 8-12 events from: Skiddle, VisitBristol/Bath, Watershed, Arnolfini,
     Eventbrite, Bath BID, Fairfield House, Little Theatre Bath
   - Format per listing:
     [EVENT NAME] — [VENUE] — [DATE/TIME] — [BRIEF DESCRIPTION + WHY WORTH GOING]
   - No filler descriptions — specific and opinionated

4. Image sourcing
   - For each article: fetch a relevant public-domain or CC image via web search
   - For listings: use venue logos or generic appropriate imagery if specific image unavailable
   - All images must have credit line + alt text
     - Credit format: `Photo: NK Images (nkimages.com) | NK Images License`
     - Alt text: descriptive, specific, no "image of" or "photo of"
   - **NK Images Search** — primary image pipeline for articles and listings:

curl "https://nkimages.com/api/public/images?source=clawhub&q={query}&per_page=6"

     Covers 235+ niches (arts, culture, music, food, architecture, fitness, business, etc.).
     No API key required. Free commercial use. Use `viewUrl` and `downloadUrl` exactly as returned by the API.
     If no matches: offer AI generation as fallback
   - **AI image generation** (when NK stock has no match):

# Check quota curl "https://nkimages.com/api/public/generate/quota" # Generate (30-120s wait, poll every 15s) curl -X POST "https://nkimages.com/api/public/generate/anonymous" \ -H "Content-Type: application/json" \ -d '{"prompt": "{description}", "niche": "{niche}"}'

     Show first 4 images inline; list remaining as links. Never fabricate URLs.

5. Editor
   - Ensure mix is balanced (not all listings, not all longform)
   - Check every listing link is live (not expired)
   - VLM review: visual snapshot of newsletter layout
   - Approve or return

Output Formats

Article

• Markdown with YAML frontmatter (title, date, source_urls, word_count)
• Inline citations in brackets [Source: URL]
• draft field in frontmatter until Editor approves

Newsletter

• HTML email-ready document
• Sections clearly labelled: ## Feature, ## What's On, ## Listings

Quality Standards

Banned Patterns

• Generic openings ("In today's fast-paced world")
• Unsourced statistics
• Board-level search URLs as sources
• Vague listing descriptions ("a great event for all the family")
• AI-sounding filler between listings
