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-metadata-sync 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 10d 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

asc metadata sync

Use this skill to keep App Store metadata in sync with App Store Connect. Prefer the canonical asc metadata workflow for app-info and version localization fields. Use the lower-level asc localizations and asc migrate commands only when the user specifically needs .strings files or legacy fastlane-format metadata.

Current canonical workflow

1. Pull canonical metadata

asc metadata pull --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"

If the app has multiple app-info records, resolve the app-info ID first and pass it explicitly:

asc apps info list --app "APP_ID" --output table
asc metadata pull --app "APP_ID" --app-info "APP_INFO_ID" --version "1.2.3" --platform IOS --dir "./metadata"

2. Edit local files

Canonical files are written under:

  • metadata/app-info/<locale>.json for app-level fields: name, subtitle, privacyPolicyUrl, privacyChoicesUrl, privacyPolicyText
  • metadata/version/<version>/<locale>.json for version fields: description, keywords, marketingUrl, promotionalText, supportUrl, whatsNew

Copyright is not a localization field. Manage it with:

asc versions update --version-id "VERSION_ID" --copyright "2026 Your Company"

3. Validate before upload

asc metadata validate --dir "./metadata" --output table

For subscription apps, include the extra Terms of Use / EULA heuristic:

asc metadata validate --dir "./metadata" --subscription-app --output table

4. Preview and apply

Run a dry run first:

asc metadata push --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" --dry-run --output table

Apply after the plan looks correct:

asc metadata push --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"

Use asc metadata apply when the user wants the apply-named command shape for the same canonical files:

asc metadata apply --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" --dry-run
asc metadata apply --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"

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.
