Content Cascade

Turn a YouTube video into a full content cascade: blog post + Twitter thread + LinkedIn post. Fetches the transcript, generates all three pieces following your voice guidelines, and optionally saves everything as drafts to Supabase.

Setup Required

Run /onboard first. It configures everything below in one pass (channel, Voice DNA, optional keys). If onboarding hasn't been run yet and no channel is configured, suggest running /onboard before proceeding. The items below are what onboarding sets up — only do them manually if the user is configuring by hand:

1. Voice prompts — Your blog/social voice guidelines live in ${CLAUDE_PLUGIN_ROOT}/skills/content-cascade/prompts/. /onboard writes a Voice DNA block into each; otherwise edit the template files directly.
2. YouTube channel — YOUR_CHANNEL_ID below is replaced with your real channel ID by /onboard.
3. Supabase (optional) — If you want auto-saving to a database, set up your Supabase project and update the config section at the bottom.
4. Apify (optional) — For reliable transcript fetching, get a free API token at https://apify.com and set APIFY_API_TOKEN env var.
5. Twitter/X (optional) — For auto-posting threads, set Twitter API credentials in ${CLAUDE_PLUGIN_ROOT}/skills/content-cascade/.env.
