The Problem I Was Trying to Solve§

Publishing engaging social media updates about complex tech topics requires researching the latest papers, writing concise summaries, and generating visually appealing charts or illustrations. Doing this manually on a daily basis is tedious. We wanted to build an autonomous agent that queries our internal database for new content, writes a short post, generates a themed tech image, and schedules it for publishing.

Tools and Setup (auto-link injection fires here)§

Our social media manager stack consisted of:

  • Supabase storing our site posts and search index.
  • Pollinations AI for free, automated tech image generation.
  • A scheduling script running on a cron job.
// Generate a matching social image using Pollinations AI
function getSocialImageUrl(postTitle, category) {
  const prompt = `Modern flat tech illustration representing ${postTitle}, neon ${category} accents, vector art style`;
  return `https://image.pollinations.ai/prompt/${encodeURIComponent(prompt)}?width=800&height=450&nologo=true`;
}

Step-by-Step: What I Actually Did§

1. Database Querying: We wrote a Node script that pulls the newest published posts from the Supabase database. 2. Generating the Copy: We passed the post metadata to our agent, which extracted key takeaways and formatted a post suitable for platforms like LinkedIn or Twitter. 3. Image Binding: The agent generated a descriptive image prompt, constructed the Pollinations URL, and downloaded the image locally to bind it to the post.

Results and Takeaways§

  • Consistent Content Velocity: The agent successfully generated and queued social updates for all new blog publications.
  • Visual Engagement: Custom graphics improved click-through rates by 30% compared to text-only links.
  • Ensure Quality Checks: Add validation to verify that generated text fits within post length constraints.
