Overview

This workflow automates the entire blog creation pipeline—from topic research to final publication. Three specialized AI agents collaborate to produce publication-ready blog posts with custom images, all saved directly to your Supabase database.

How It Works

1. Research Agent (Topic Discovery) - Triggers: Runs on schedule (default: daily at 4 AM) - Process: - Fetches existing blog titles from Supabase to avoid duplicates - Uses Google Search + RSS feeds to identify trending topics in your niche - Scrapes competitor content to find content gaps - Generates detailed topic briefs with SEO keywords, search intent, and differentiation angles - Output: Comprehensive research document with SERP analysis and content strategy

2. Writer Agent (Content Creation) - Triggers: Receives research from Agent 1 - Process: - Writes full blog article based on research brief - Follows strict SEO and readability guidelines (no AI fluff, natural tone, actionable content) - Structures content with proper HTML markup - Includes key sections: hook, takeaways, frameworks, FAQs, CTAs - Places image placeholders with mock URLs (https://db.com/image1, etc.) - Output: Complete JSON object with title, slug, excerpt, tags, category, and full HTML content
