Social auto-post FB + IG

Mon / Wed / Fri at 14:00 UTC — Claude writes the copy, HCTI renders the image, n8n publishes to Facebook and Instagram.

Finish setup (one time)

Edit .env on the server with ANTHROPIC_API_KEY, Facebook Page ID/token, and IG user ID.
In n8n → Credentials → create HCTI Basic Auth (htmlcsstoimage.com).
Open the imported workflow → Execute Workflow to dry-run.
Toggle workflow Active when posts look good.

Prompt and image template load automatically from claude-system-prompt.md and image-template.html — no paste into n8n variables.

Schedule: Mon → real estate · Wed → roofing · Fri → solar. Full guide: SETUP.md in the project folder.
