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 8d 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.

Origin

This is a copy

86% identical to asc-crash-triage — 24 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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 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"

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.
