How do I set a default compression quality?

You can define your preferred quality level (0-100) in an EXTEND.md file located in your project's .baoyu-skills folder or your home directory.

Does it overwrite my original files?

By default, it creates optimized versions. You can use the --keep option to ensure your original source files are preserved during conversion.

Can I process an entire folder of images at once?

Yes, by providing a directory path and using the --recursive (or -r) flag, you can optimize all images in a folder and its subdirectories.

Which compression engines does this skill support?

It intelligently detects and uses the best available tool on your path, prioritizing sips (macOS), cwebp, ImageMagick, and Sharp.
