Triage TestFlight crashes, beta feedback, and performance diagnostics using asc. Use when the user asks about TF crashes, TestFlight crash reports, beta tester feedback, app hangs, disk writes, launch diagnostics, or wants a crash summary for a build or app.

asc crash triage Use this skill to fetch, analyze, and summarize TestFlight crash reports, beta feedback, and performance diagnostics. Workflow 1. Resolve the app ID if not provided (use asc apps list ). 2. Fetch data with the appropriate command. 3. Parse JSON output and present a human readable summary. TestFlight crash reports List recent crashes (newest first): asc testflight crashes list app "APP ID" sort createdDate limit 10 Filter by build: asc testflight crashes list app "APP ID" build id "BUILD ID" sort createdDate limit 10 Filter by device/OS: asc testflight crashes list app "APP ID" device model "iPhone16,2" os version "18.0" All crashes: asc testflight crashes list app "APP ID" paginate Table view: asc testflight crashes list app "APP ID" sort createdDate limit 10 output table TestFlight beta feedback List recent feedback (newest first): asc testflight feedback list app "APP ID" sort createdDate limit 10 With screenshots: asc testflight feedback list app "APP ID" sort createdDate limit 10 include screenshots Filter by build: asc testflight feedback list app "APP ID" build id "BUILD ID" sort createdDate All feedback: asc testflight feedback list app "APP ID" paginate Performance diagnostics (hangs, disk writes, launches) Requires a build ID. Resolve via asc builds info app "APP ID" latest platform IOS or asc builds list app "APP ID" sort uploadedDate limit 5 . List diagnostic signatures: asc performance diagnostics list build id "BUILD ID" Filter by type: asc performance diagnostics list build id "BUILD ID" diagnostic type "HANGS" Types: HANGS , DISK WRITES , LAUNCHES View logs for a signature: asc performance diagnostics view id "SIGNATURE ID" Download all metrics: asc performance download build id "BUILD ID" output ./metrics.json Resolving IDs App ID from name: asc apps list name "AppName" or asc apps list bundle id "com.example.app" Latest build ID: asc builds info app "APP ID" latest platform IOS Recent builds: asc builds list app "APP ID" sort uploadedDate limit 5 Set default: export ASC APP ID="APP ID" Summary format When presenting results, organize by severity and frequency: 1. Total count — how many crashes/feedbacks in the result set. 2. Top crash signatures — group by exception type or crash reason, ranked by count. 3. Affected builds — which build versions are impacted. 4. Device & OS breakdown — most affected device models and OS versions. 5. Timeline — when crashes started or spiked. For performance diagnostics, highlight the highest weight signatures first. Notes Default output is JSON; use output table or output markdown for quick human review. Use paginate to fetch all pages when doing a full analysis. Use pretty with JSON for debugging command output. Crash data from App Store Connect may have 24 48h delay.
