name: podcast-to-substack

description: Publish podcast episodes from RSS + Notion to Substack with reliable Apple Podcasts embedding and image extraction, then generate LinkedIn-ready companion posts. Use when asked to run or improve podcast-to-substack workflows, fix Notion image fetch failures, prevent Substack embed-as-text issues, or cross-post episode summaries to LinkedIn.

# Podcast Substack + LinkedIn

Run this workflow when handling Realist podcast episode publishing.

Inputs

  • RSS feed URL
  • Notion data source/database ID with episode scripts
  • Notion API key (`NOTION_API_KEY` or `~/.config/notion/api_key`)
  • Substack publish access

    • Workflow

    1. Fetch recent episodes:

    python3 scripts/fetch_rss.py "$RSS_URL" 3

    2. Fetch episode script + images from Notion (recursive block traversal, image downloads included):

    python3 scripts/fetch_notion_episode.py "EPISODE_NUMBER"

    3. Build Substack draft content from script text.

    4. Publish with stable embed behavior using the playbook in `references/substack-embed-playbook.md`.

    5. Generate LinkedIn post copy from the same content:

    python3 scripts/render_linkedin_post.py --json-file episode.json

    6. Post or queue the LinkedIn copy.

    Non-negotiable rules

  • Do not use iframe code or markdown links for podcast embeds in Substack.
  • Prefer duplicating the existing Substack draft template that already has a working embed block.
  • If creating a fresh post, use `/embed` and confirm the player card renders before publishing.
  • Use top-level Apple Podcasts show URL for reliable fallback.

    • References

  • Substack embed behavior: `references/substack-embed-playbook.md`
  • LinkedIn formatting: `references/linkedin-playbook.md`
