How to Automate Facebook 9:16 Reels & Multi-Photo Carousels with an AI Agent

Because the official Meta Graph API prohibits direct publishing to personal Facebook profile timelines, automating vertical 9:16 Reels and 2–10 ordered photo carousels requires deterministic DOM interaction inside your real logged-in browser. Here is how to set it up in 3 minutes using WindSkills.

Step 1: Install the Deterministic SKILL.md Modules

After downloading your package from Gumroad, extract the skill folders into your agent's skill directory (for example, ~/.claude/skills/ for Claude Code or ~/.gemini/config/skills/ for Google Antigravity). Your agent automatically discovers the YAML frontmatter and execution steps.

Step 2: Automate Vertical 9:16 Facebook Reels (neo-facebook-post-reel)

Personal Facebook Reels require navigating a two-stage Reels Studio modal (Upload → Next → Next → Describe your reel... → Publish). When you trigger neo-facebook-post-reel, your AI agent attaches your vertical 9:16 MP4 (up to 90 seconds), waits for Facebook's video frame processing indicator to complete, injects your caption into the contenteditable lexical input, and verifies live publication.

Step 3: Automate 2–10 Ordered Photo Carousels (neo-facebook-post-photo-carousel)

Multi-photo storytelling posts lose impact when images upload out of sequence. The neo-facebook-post-photo-carousel skill enforces strict sequential file attachment for 2 to 10 high-resolution images on your personal Facebook timeline, verifies thumbnail rendering order in the composer, types your caption with human-like pacing, and publishes with zero manual clicks.
