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 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

asc — App Store Connect from the CLI

asc is installed via Homebrew (brew install asc). It is the only tool that should touch App Store Connect here — do not hand-roll JWTs or curl the API.

This skill is a router. Read the one reference that matches the task, not the whole set. Each reference is a self-contained playbook with the exact commands.

Before anything

Every command needs credentials. Check first:

asc auth status      # active profile
asc doctor           # diagnose a broken or missing setup

If nothing is stored, register a key (Key ID + Issuer ID + .p8 from https://appstoreconnect.apple.com/access/integrations/api):

asc auth login --name <label> --key-id <KEY_ID> --issuer-id <UUID> \
  --private-key <path/to/AuthKey_XXXX.p8> --network

Most commands need an app or build ID rather than a name — see references/asc-id-resolver.md.

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.
