(2) Checking or listing build upload records: "asc builds uploads list/get/delete" (3) Linking a build to an App Store version before submission: "asc versions set-build" (4) Adding or removing a beta group from a build for TestFlight distribution (5) Setting TestFlight "What's New" notes: "asc builds update-beta-notes" (6) User says "upload my build", "distribute to TestFlight", "set what's new", "link build to version"

When the user wants to monitor, triage, or reduce their app's crash rate — including setting up Crashlytics, prioritizing which crashes to fix first, interpreting crash data, and understanding how crashes affect App Store ranking. Use when the user mentions "crash", "crashlytics", "crash rate", "ANR", "app not responding", "crash-free sessions", "crash-free users", "symbolication", "stability", "firebase crashes", "app crashing", or "crash report". For overall analytics setup, see app-analytics.
