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