asc-app-create-ui

asc-app-create-ui is a skill for Claude Code, Codex from blitzdotdev/blitz-mac. It costs 19 tokens per session (1,576 once invoked), scanned A, original, Apache-2.0.

A procedure for creating an app record in Apple's App Store Connect using Apple's internal Iris API and a saved Blitz web session. It uses a bundle identifier, SKU, app name, and primary language.

In plain words
What is it for?
Use it to create the App Store Connect entry for a new iPhone or iPad app from its bundle identifier and related app details.
Why use it?
It automates the initial app-record setup when the required Apple web session is available. It requires choosing a language and may need Apple web authentication first.

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-app-create-ui 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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create an App Store Connect app using Apple's iris API. Authentication is handled via a web session file at ~/.blitz/asc-agent/web-session.json managed by Blitz.

Extract from the conversation context:

  • bundleId — the bundle identifier (e.g. com.blitz.myapp)
  • sku — the SKU string (may be provided; if missing, generate one from the app name)

Workflow

1. Check for an existing web session

test -f ~/.blitz/asc-agent/web-session.json && echo "SESSION_EXISTS" || echo "NO_SESSION"
  • If NO_SESSION: call the asc_web_auth MCP tool first. Wait for it to complete before proceeding.
  • If SESSION_EXISTS: proceed.

2. Ask the user for the primary language

Ask what primary language/locale the app should use. Common choices: en-US (English US), en-GB (English UK), ja (Japanese), zh-Hans (Simplified Chinese), ko (Korean), fr-FR (French), de-DE (German).

3. Derive the app name

Take the last component of the bundle ID after the final ., capitalize the first letter. Confirm with the user.

4. Create the app via iris API

Use the following self-contained script. Replace BUNDLE_ID, SKU, APP_NAME, and LOCALE with the resolved values. Do not print or log cookies.

Key differences from the public REST API:

  • Uses appstoreconnect.apple.com/iris/v1/ (not api.appstoreconnect.apple.com)
  • Authenticated via web session cookies (not JWT)
  • Uses appInfos relationship (not bundleId relationship)
  • App name goes on appInfoLocalizations (not appStoreVersionLocalizations)
  • Uses ${new-...} placeholder IDs for inline-created resources
