Rudrankriyam asc crash triage
Skill JordanCoin/ios-skills-collection/skills/rudrankriyam--asc-crash-triage
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.From its SKILL.md

3 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 4 stars4 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
- runs commandsInstructs the agent to run 8 commands, including `asc apps list` and 7 more.

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 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 "BUILD_ID" - Filter by type:
asc performance diagnostics list --build "BUILD_ID" --diagnostic-type "HANGS"- Types:
HANGS,DISK_WRITES,LAUNCHES
- Types:
- View logs for a signature:
asc performance diagnostics view --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 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:
- 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.
