Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.01445 |
| Opus 5 | $0.00036 | $0.00723 |
| Sonnet 5 | $0.00014 | $0.00289 |
| Haiku 4.5 | $0.00007 | $0.00145 |
Grade A, and why
asc-crash-logs scanned grade A with 1 finding 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 7d 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.

ASC Crash Logs
Retrieve tester-reported crash feedback and fully-symbolicated crash logs straight from the App Store Connect API — no device, no Xcode Organizer, no waiting for the owner to AirDrop an .ips file.
When to Use
- A TestFlight tester (or the owner) reports a crash and you need the stack trace now.
- Xcode Organizer fails with "Xcode failed to locate iOS App with App Store Identifier …" — the Organizer only resolves apps it has a local archive/project association for, which breaks on shared or freshly-migrated checkouts. The API route bypasses that entirely.
- You want to confirm whether a new crash is a known signature or a regression across builds.
Don't use for crashes that never went through TestFlight (local debug runs) — those are on the device or in Console.
The two-endpoint reality (verified 2026-08-18)
| Endpoint | Status |
|---|---|
GET /v1/apps/{appId}/betaFeedbackCrashSubmissions |
Works. Lists tester crash feedback (comment, build, device, OS, uptime). |
GET /v1/betaFeedbackCrashSubmissions/{id}/crashLog |
Works. Returns the full crash log as attributes.logText. |
GET /v1/betaFeedbackCrashSubmissions (top level) |
403 — collection fetch is forbidden; you must go through the app relationship. |
GET /v1/builds/{id}/diagnosticSignatures?filter[diagnosticType]=CRASH |
400 — the filter only accepts DISK_WRITES, HANGS, LAUNCHES. Aggregate crash signatures are NOT in the public API. |
Recipe
1. Auth: ES256 JWT from the ASC API key
Use the bundled asc_jwt.rb (requires the jwt gem — present in any repo with a Fastlane Gemfile). The script reads three env vars; inject them however the current repo manages secrets:
# Aether family repos: Doppler project "apple-dev", config "dev"
TOKEN=$(doppler run --project apple-dev --config dev -- \
ruby "$(dirname "$0")/asc_jwt.rb" 2>/dev/null | tail -1)
Required env vars: APP_STORE_CONNECT_API_KEY_KEY_CONTENT (the .p8 contents),
APP_STORE_CONNECT_API_KEY_ISSUER_ID, APP_STORE_CONNECT_API_KEY_KEY_ID.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

asc-crash-logs is a skill published in the GitHub repository markdavidgan/apple-dev-skills (5 stars, last pushed 11d ago), licensed MIT. It adds 71 tokens to every session and 1,445 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
