Publish podcast episodes from RSS and Notion to Substack with Apple Podcasts embeds and images, then generate LinkedIn-ready companion posts.
--- 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: ```bash python3 scripts/fetch_rss.py "$RSS_URL" 3 ``` 2. Fetch episode script + images from Notion (recursive block traversal, image downloads included): ```bash 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: ```bash 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`
