asc-cli-usage

A reference for using the asc command-line tool with App Store Connect, Apple’s service for managing apps, builds, testing, and releases. It covers command discovery, flags, JSON or table output, pagination, authentication, and timeouts.

In plain words
What is it for?
Use it to design or run asc commands, authenticate with App Store Connect, retrieve complete paginated results, choose output formats, and set request or upload timeouts.
Why use it?
It reduces guesswork when choosing commands and options, and helps prevent interactive or unconfirmed operations during automated workflows.

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-cli-usage 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 yesterday.

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.

What it actually says

asc cli usage

Use this skill when you need to run or design asc commands for App Store Connect.

Command discovery

  • Always use --help to discover commands and flags.
    • asc --help
    • asc builds --help
    • asc builds list --help

Flag conventions

  • Use explicit long flags (e.g., --app, --output).
  • No interactive prompts; destructive operations require --confirm.
  • Use --paginate when the user wants all pages.

Output formats

  • Default output is minified JSON.
  • Use --output table or --output markdown only for human-readable output.
  • --pretty is only valid with JSON output.

Authentication and defaults

  • Prefer keychain auth via asc auth login.
  • Fallback env vars: ASC_KEY_ID, ASC_ISSUER_ID, ASC_PRIVATE_KEY_PATH, ASC_PRIVATE_KEY, ASC_PRIVATE_KEY_B64.
  • ASC_APP_ID can provide a default app ID.

Timeouts

  • ASC_TIMEOUT / ASC_TIMEOUT_SECONDS control request timeouts.
  • ASC_UPLOAD_TIMEOUT / ASC_UPLOAD_TIMEOUT_SECONDS control upload timeouts.

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.
