macos-notarization-packager

macos-notarization-packager is a skill for Claude Code, Codex from Xopoko/build-swift-apps. It costs 46 tokens per session (436 once invoked), scanned A, original, MIT.

A guide for preparing a macOS app for distribution, including app archives, exported app bundles, code signing, and notarization. Notarization is Apple's review step that helps macOS trust software downloaded from outside the App Store.

In plain words
What is it for?
Use it to validate an app bundle, inspect its frameworks and helper tools, check signing prerequisites, and prepare a signed distributable or notarization-ready artifact.
Why use it?
It helps find packaging, nested-code, entitlement, hardened-runtime, and distribution-readiness problems before shipping.

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

macos-notarization-packager 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 9d 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.

What it actually says

macOS Notarization Packager

Before invoking Apple-only binaries, confirm the execution context is macOS. From Windows or Linux, run those steps in a Mac SSH project or through an already configured remote transport; do not retry missing Apple binaries locally.

Quick Start

Use this skill when the work is about shipping the app rather than merely running it locally: archives, exported app bundles, notarization readiness, hardened runtime, or distribution validation.

Use macos-signing-inspector for local signing/trust diagnosis on an existing artifact. Use appstore-notary-runner when the artifact is ready and the task is to run asc notarization submit/status/log/staple commands. For raw pkgbuild/productbuild/notarytool command forms, see ../macos-signing-inspector/references/binary-tools.md.

Workflow

  1. Confirm the distribution goal.

    • Local archive validation
    • Signed distributable app
    • Notarization troubleshooting
  2. Inspect the artifact.

    • Validate app bundle structure.
    • Check nested frameworks, helper tools, and entitlements.
  3. Inspect signing and runtime prerequisites.

    • Hardened runtime
    • Signing identity
    • Nested code signatures
    • Required entitlements
  4. Explain notarization readiness or failure.

    • Separate packaging issues from trust-policy symptoms.
    • Point to the minimum follow-up validation commands.

Guardrails

  • Do not present notarization as required for ordinary local debug runs.
  • Call out when you lack the actual exported artifact and are inferring from project settings.
  • Keep advice concrete and verifiable.

Output Expectations

Provide:

  • what artifact or settings were inspected
  • whether the app looks distribution-ready
  • the top missing prerequisite or failure mode
  • the next validation or repair step

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.
