What it does

You get your daily social posts automatically published to Instagram, Facebook, and LinkedIn at 7 PM based on your Google Sheets calendar. The agent handles image and reel formats, adds hashtags, and updates your sheet with the results so you never miss a scheduled update.

Watch out for

Meta API requires specific image aspect ratios so validate media dimensions before uploading to prevent rejection errors.
LinkedIn access tokens expire quickly so implement a refresh token flow to avoid authentication failures during long runs.
Google Sheets has row limits for bulk updates so batch write operations only after all social posts succeed or fail individually.
Duplicate posts can occur if the trigger fires multiple times so add a unique transaction ID check in the sheet before processing.
