About asc-crash-triage

asc-crash-triage is a skill for analyzing TestFlight crash reports, beta feedback, and performance diagnostics. It uses the asc CLI to retrieve and filter data, then organizes findings into a human-readable summary.

Key features

  1. 01List and filter crash reports
  2. 02Review beta feedback and screenshots
  3. 03Inspect hang, disk-write, and launch diagnostics
  4. 04Download performance metrics
  5. 05Summarize results by severity and frequency

Use cases

  1. 01Find recent crashes for a particular build
  2. 02Compare crashes across device models and OS versions
  3. 03Review beta feedback with screenshots
  4. 04Identify high-weight performance diagnostic signatures

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/rorkai/app-store-connect-cli-skills --skill asc-crash-triage

After installing, type/asc-crash-triagein Claude Code to confirm it loaded.

Details

From the project README

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, using --output json for responses that will be parsed. For performance download, --output is the destination file path.
  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

  • Read-command output defaults to table in a terminal and JSON in pipes or CI. Select the format explicitly when parsing results.
  • 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.
