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 testflight crashes list --app "APP_ID" --sort -createdDate --limit 10- Filter by build:
asc testflight crashes list --app "APP_ID" --build "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 "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 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
- 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" or asc 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 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.
