PolicyEngine research lookup

Find existing PolicyEngine articles to cite as evidence or to model tone against. PolicyEngine has published ~185 articles — US and UK policy analyses, model/methodology notes, and org announcements. Paths below are verified against the policyengine-app-v2 mirror.

Where posts live

In policyengine-app-v2:

• Article bodies (plain markdown, some Jupyter .ipynb): app/src/data/posts/articles/<filename>
• Post index (title, description, date, tags, authors, image): app/src/data/posts/posts.json
• Author records (slug → name/bio): app/src/data/posts/authors.json

Article files are plain markdown — metadata is not in per-file YAML frontmatter. Each post's title, date, tags, and authors live in posts.json, keyed to the article's filename; the authors field holds slugs that resolve in authors.json. A posts.json entry:

{
  "title": "How we used Claude Code to apply for the Public Benefit Innovation Fund",
  "description": "Treating writing as software development...",
  "date": "2025-08-28",
  "tags": ["us", "org", "ai", "featured"],
  "authors": ["max-ghenis"],
  "filename": "policyengine-atlas-pbif-grant.md",
  "image": "policyengine-atlas-demo.png"
}

A post's public URL is policyengine.org/<country>/research/<filename-without-extension>.
