Summary
If you've ever had App Store Connect reject your screenshots because they're 2 pixels off or have alpha transparency, this skill is the workflow you need. It wraps the `asc` CLI and macOS `sips` to validate, resize, and strip alpha from screenshots before upload. The key insight is treating `asc screenshots sizes` as the source of truth instead of hardcoding dimensions that go stale when Apple changes requirements. It also handles the annoying Unicode space bug in macOS screenshot filenames and includes a clever JPEG round-trip trick to remove alpha channels. The guardrails are smart: always validate before upload, never overwrite originals, and don't stretch images across incompatible aspect ratios unless you're okay with the distortion.
