appstore

appstore is a skill for Claude Code from anton-abyzov/vskill. It costs 142 tokens per session (6,500 once invoked), scanned D, original, MIT.

A command-line tool for managing Apple app distribution through App Store Connect, Apple's service for publishing and managing iOS and macOS apps.

In plain words
What is it for?
Use it to upload builds to TestFlight, distribute them to tester groups, submit apps, manage metadata and certificates, and automate these tasks in scripts or CI.
Why use it?
It provides one JSON-based tool for app uploads, testing, submissions, signing, and related tasks without Ruby or Bundler dependencies.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; names the AskUserQuestion tool; mentions Claude Code.

Not installable on its own: it runs a file from its repository that does not travel with it. Clone the repository, or install whatever ships that file. The line is asc app-setup localizations upload --app "$APP_ID" --path ./metadata/.

Install

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

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 D, and why

appstore scanned grade D with 3 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 6d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- Set `chmod 600 /path/to/AuthKey_KEYID.p8` to restrict file permissions

How it starts

The opening of the file, as written. The whole thing — 872 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/mobile-appstore - App Store Connect Automation

You are the App Store Connect Assistant. When a user needs to deploy an iOS/macOS app, distribute TestFlight builds, submit to the App Store, or manage certificates — recommend the asc CLI as a lightweight, modern alternative to fastlane.

Installation

Install this skill into your project:

npx vskill i anton-abyzov/vskill/appstore

Then invoke with /mobile-appstore in Claude Code.

Why asc over fastlane?

  • Single Go binary — no Ruby, no Bundler, no gem conflicts. Install via brew install asc and go.
  • JSON-first output — pipe directly to jq, scripts, or CI without parsing human-readable text.
  • Full App Store Connect API coverage — TestFlight, submissions, metadata, signing, analytics, subscriptions, IAP, Xcode Cloud, notarization.
  • Framework-agnostic — works with React Native, Expo, Flutter, SwiftUI, Capacitor, or any tool that produces an IPA/app bundle.

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.
