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-privacy-nutrition-labels 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 2mo 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.

asc privacy nutrition labels

Use this skill to configure App Store privacy nutrition labels for an app. This is the "App Privacy" section in App Store Connect where you declare what data your app collects, what purposes it's used for, and how it's protected.

When to use

  • User says "set up privacy labels", "configure nutrition labels", "app privacy", "data collection declaration"
  • The submission readiness checklist shows "Privacy Nutrition Labels" as incomplete
  • User is preparing an app for first submission and needs to declare data practices
  • User needs to update privacy declarations after adding new data collection

Preconditions

  • Web session authenticated (cached in keychain from prior asc web auth login, or call asc_web_auth MCP tool)
  • Know your app ID (ASC_APP_ID or --app)

Data Model

Each privacy declaration is a tuple of three dimensions:

Categories (what data is collected)

Grouped by type:

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.
