asc-api

A workflow for automating App Store Connect through Apple's official REST API. It uses local credentials and short-lived tokens to work with app, build, and version data without exposing secrets.

In plain words
What is it for?
Use it to build or run scripts that inspect, create, update, or delete supported App Store Connect resources.
Why use it?
It provides a safer, repeatable way to inspect or change App Store Connect resources from a Mac.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-api 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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/asc_client.py, scripts/inspect_openapi.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ASC API

Use this skill to build or run local App Store Connect automation without exposing secrets to Codex, logs, repositories, or remote model context.

The default pattern is:

  1. Keep credentials outside every project in ~/.asc_secrets.
  2. Keep the .p8 private key outside every project, such as under ~/.ssh/.
  3. Generate a 20-minute JWT only inside the local Python process.
  4. Send requests directly to https://api.appstoreconnect.apple.com/.
  5. Print only safe response summaries, never tokens or request headers.

Hard Security Rules

Never ask the user to paste ASC_KEY_ID, ASC_ISSUER_ID, .p8 contents, JWTs, or Authorization headers into chat.

Never run commands that reveal secrets, including:

  • cat ~/.asc_secrets
  • cat *.p8
  • printenv
  • env
  • any command that prints ASC_*, PRIVATE KEY, Bearer, or Authorization

Never add real credentials to a project file, git-tracked file, script, fixture, markdown doc, shell history snippet, or test output.

Never print token, auth_headers, response.request.headers, PreparedRequest.headers, or full request dumps. On failures, print only:

  • HTTP method and endpoint path
  • status code
  • response body text or JSON
  • redacted diagnostics such as Authorization: <redacted>

If authentication, signing, missing-file, missing-field, permission, or ASC 401/403 errors occur, tell the user to manually inspect ~/.asc_secrets and the .p8 path on their own machine. Explicitly state that Codex cannot and should not access the user's secret file, private key, JWT, or Authorization header.

For mutating live ASC operations (POST, PATCH, DELETE), confirm the target app/resource and intended changes with the user before executing. After generating final task JSON, stop and show it to the user. Do not upload or modify App Store Connect until the user explicitly confirms that final JSON. For read-only GET, proceed when the task is clear.

Local Credential File

Expect the user to create this file manually outside the project. If they have not done so yet, direct them to docs/asc-api-setup.md in the repository root for a complete step-by-step guide covering key generation, .p8 file storage, and setup verification.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

asc-api is a skill published in the GitHub repository raydeveloperF/App-Store-Connect-release-kit (2 stars, last pushed 2mo ago), licensed MIT. It adds 122 tokens to every session and 3,485 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
