SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires curl, jq, and includes scripts (resource) components.

What problem does it solve?

This Skill automates the multi-step process of publishing image, carousel, and reel posts to Instagram by handling image hosting, media container creation, and final publishing so users do not need to manually upload files, assemble containers, or run multiple API calls.

Core Features & Use Cases

  • Automated Image Hosting: Upload local images to ImgBB and return public URLs for use with the Instagram Graph API.
  • Graph API Orchestration: Create media containers for single images, carousels, and reels and publish them to an Instagram Business/Creator account.
  • Onboarding and Safety: Guided credential setup, validation of inputs, and a mandatory explicit user confirmation step before publishing.
  • Use Cases: Publish article images generated by content workflows, post designer assets as carousels, or programmatically publish reels sourced from local files or remote URLs.

Quick Start

Ask the skill to publish a local image with the caption "New article published" and provide the image path so it uploads the image, creates the media container, and publishes the post to your Instagram Business account.
