If you're babysitting App Store Connect builds, this gives you command-line control over the whole lifecycle. You can find the latest build for a version, check processing status, and most usefully, bulk-expire old builds with a dry run preview before committing. The skill steers you toward the end-to-end publish commands with built-in waiting rather than manual upload-then-wait workflows. Honestly most valuable for cleanup, the expire-all command with --older-than 90d keeps your build list from becoming archaeological. Supports polling with configurable intervals if you need to block on processing.
