# ASC Crash Triage

ASC Crash Triage fetches and summarizes TestFlight crashes, beta feedback, and performance diagnostics from App Store Connect. Use it when you need to investigate crashes, hangs, disk writes, launches, or beta tester reports for an app or build.

**Install:**

```bash
npx degit https://github.com/rorkai/app-store-connect-cli-skills/tree/main/skills/asc-crash-triage ~/.claude/skills/asc-crash-triage
```

## 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.
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 "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`
- 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"` 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

- 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.
