This one taps into Fal AI's upscaling models to bump up resolution on images and video using AI enhancement. You'd reach for it when you need to clean up low-res assets, prepare media for higher-quality display, or recover detail from compressed sources. The skill wraps the Fal API, so you're getting access to their trained models without building the integration yourself. The source is pretty bare bones on implementation specifics, but it's marked safe and straightforward to invoke. Honestly most useful when you're already in a Claude workflow and need quick upscaling without context switching to another tool or writing API calls by hand.
