Social Content – AI Planner (fills Content Queue)

Once a week, AI writes the week's captions and images and adds them to the content queue as pending approval.

Workflow file is complete and imports inactive. No live run is recorded in the files.

Reads the queue to see which topics and time slots are already taken this week.
Asks the chosen AI provider for the remaining posts as structured JSON.
Validates each post and always sets it to pending approval, never approved.
Optionally generates an image and uploads it to Zernio media for a public image URL.
Appends the drafts to the queue and writes a planner log row.

Add a planner_log tab (time, posts_created, notes) to the content Sheet.
Create credentials only for the AI provider you'll use, plus Google Sheets and Zernio if images are on.
Set ai_provider and image_provider in Config.
Review drafts in the Sheet and set the good ones to approved for the posting workflow.

Zernio upload URLs expire after 7 days unless a post uses them, so approve and publish within the week.
