asc-crash-triage

asc-crash-triage is a skill for Claude Code from hanamizuki/solopreneur. It costs 60 tokens per session (832 once invoked), scanned A, a copy of asc-crash-triage, MIT.

A workflow for examining TestFlight crash reports, beta tester feedback, and performance diagnostics. TestFlight is Apple's service for distributing pre-release app builds to testers.

In plain words
What is it for?
It helps investigate crashes, hangs, disk-writing and launch problems, review beta feedback, include screenshots, and summarize issues for an app or build.
Why use it?
Crash and feedback data is spread across reports and often needs filtering by build, device, or operating system before it is useful. This workflow gathers the data and turns it into a readable summary.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

asc-crash-triage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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"

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
