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
- Fetch recent episodes:
python3 scripts/fetch_rss.py "$RSS_URL" 3
- Fetch episode script + images from Notion (recursive block traversal, image downloads included):
python3 scripts/fetch_notion_episode.py "EPISODE_NUMBER"
- Build Substack draft content from script text.
- Publish with stable embed behavior using the playbook in
references/substack-embed-playbook.md.
- Generate LinkedIn post copy from the same content:
python3 scripts/render_linkedin_post.py --json-file episode.json
- 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.
