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-localize-metadata 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 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.

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-localize-metadata — 15 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.

How it starts

The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.

asc localize metadata

Use this skill to pull English (or any source locale) App Store metadata, translate it with LLM, and push translations back to App Store Connect — all automated.

Command discovery and output conventions

  • Always confirm flags with --help for the exact asc version:
    • asc localizations --help
    • asc localizations download --help
    • asc localizations upload --help
    • asc apps info edit --help
  • Prefer explicit long flags (--app, --version, --version-id, --type, --app-info).
  • Default output is JSON; use --output table only for human verification steps.
  • Prefer deterministic ID-based operations. Do not "pick the first row" via head -1 unless the user explicitly agrees.

Preconditions

  • Auth configured (asc auth login or ASC_* env vars)
  • Know your app ID (asc apps list to find it)
  • At least one locale (typically en-US) already has metadata in App Store Connect

Supported Locales

App Store Connect locales for version and app-info localizations:

ar-SA, ca, cs, da, de-DE, el, en-AU, en-CA, en-GB, en-US,
es-ES, es-MX, fi, fr-CA, fr-FR, he, hi, hr, hu, id, it,
ja, ko, ms, nl-NL, no, pl, pt-BR, pt-PT, ro, ru, sk,
sv, th, tr, uk, vi, zh-Hans, zh-Hant

Two Types of Metadata

Version Localizations (per-release)

Fields: description, keywords, whatsNew, supportUrl, marketingUrl, promotionalText

App Info Localizations (app-level, persistent)

Fields: name, subtitle, privacyPolicyUrl, privacyChoicesUrl, privacyPolicyText

Workflow

Step 1: Resolve IDs

# Find app ID
asc apps list --output table

# Find latest version ID
asc versions list --app "APP_ID" --state READY_FOR_DISTRIBUTION --output table
# or for editable version:
asc versions list --app "APP_ID" --state PREPARE_FOR_SUBMISSION --output table

# Find app info ID (for app-level fields like name/subtitle)
asc apps info list --app "APP_ID" --output table

Notes:

  • Version-localization fields (description, keywords, whatsNew, etc.) are per-version.
  • App-info fields (name, subtitle, privacy URLs/text) are app-level and use --type app-info.
  • If you only have names (app name, version string) and need IDs deterministically, use asc-id-resolver.

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.
