Summary
Preparing App Store Connect screenshots is tedious, and this skill automates the resize and validation workflow using macOS sips and the asc CLI. It pulls current screenshot dimensions directly from asc instead of relying on stale hardcoded tables, which matters because Apple changes requirements. The workflow covers filename sanitization (Unicode spaces break tools), alpha channel stripping (ASC rejects transparency), batch resizing to exact pixel dimensions, and validation before upload. It's opinionated about preserving originals and validating everything with asc before you touch the upload command. If you ship iOS or Mac apps and wrestle with screenshot prep every release, this condenses the tedious parts into a repeatable pattern.
