/socialforge:create-previews — Preview Generator

Generate realistic platform mockups showing exactly how each post will appear when published.

Process

1. For each post × each platform:
   • Load the generated/composed image
   • Load the adapted copy
   • Select platform preview template (assets/preview-templates/)
   • Inject: profile avatar, brand name, handle, image, copy, hashtags, timestamp
   • Render via Playwright → PNG preview
2. Save to production/previews/post-{id}-{platform}-preview.png

Templates

• linkedin-post.html | linkedin-carousel.html
• instagram-feed.html | instagram-story.html
• twitter-post.html | facebook-post.html
• youtube-thumbnail.html

Timeout & Fallback

• Per preview: 10-second timeout. If Playwright hangs, save raw image + copy as fallback.
