File contents

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
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.
