What This Skill Does
Wraps ImageMagick CLI operations for image manipulation tasks in Moltbot. Covers background removal, resizing, format conversion, watermarking, and batch processing. Includes a helper script for removing solid-color backgrounds with configurable tolerance.
Bundles the most common ImageMagick one-liners into reusable scripts so you don't have to look up flag syntax each time.
When to use it
- Remove white background from a product icon
- Batch generate iOS app icon sizes from a single source
- Convert PNG assets to WebP for web delivery
- Add a watermark to a base image
- Apply rounded corners to an app screenshot
