/socialforge:create-previews — Preview Generator

Generate a preview card per platform (post copy, image, platform badge) to check copy, line breaks and crop before publishing. The card is one built-in layout with the platform named; it is not a replica of the platform's feed.

Execution gate

Rendering writes preview images under production/previews/. State the scope (posts x platforms, destination) and proceed only on an explicit yes; any other reply cancels with nothing written.

Process

1. For each post × each platform:
   • Load the generated/composed image
   • Load the adapted copy
   • Use the built-in card (or assets/preview-templates/<platform>.html if you supplied one; none ship)
   • Inject: brand name and handle, platform badge, image and the post copy (hashtags included in the copy passed in)
   • Render via Playwright → PNG preview
2. Save to production/previews/post-{id}-{platform}-preview.png

Layouts

One built-in card serves every platform. To get a platform-specific layout, put <platform>.html in assets/preview-templates/ using the placeholders {{name}}, {{handle}}, {{platform}}, {{image_uri}} and {{copy}}. No templates ship.

Timeout & Fallback

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