asc-notarization

asc-notarization is a skill for Claude Code from hanamizuki/solopreneur. It costs 47 tokens per session (1,601 once invoked), scanned C, a copy of asc-notarization, MIT.

A workflow for packaging and notarizing macOS apps for distribution outside the Mac App Store. Notarization is Apple's security check that lets macOS verify an app has been reviewed for harmful software.

In plain words
What is it for?
It helps prepare an Xcode macOS app, sign it with a Developer ID certificate, submit it to Apple for notarization, and produce a distributable app.
Why use it?
Apps distributed directly to Mac users can trigger security warnings without Developer ID signing and notarization. This workflow covers the archive, export, signing, and Apple submission steps.

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 C, and why

asc-notarization scanned grade C with 2 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 20d 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

macOS Notarization

Use this skill when you need to notarize a macOS app for distribution outside the App Store.

Preconditions

  • Xcode installed and command line tools configured.
  • Auth is configured (asc auth login or ASC_* env vars).
  • A Developer ID Application certificate in the local keychain.
  • The app's Xcode project builds for macOS.

Preflight: Verify Signing Identity

Before archiving, confirm a valid Developer ID Application identity exists:

security find-identity -v -p codesigning | grep "Developer ID Application"

If no identity is found, create one at https://developer.apple.com/account/resources/certificates/add (the App Store Connect API does not support creating Developer ID certificates).

Fix Broken Trust Settings

If codesign or xcodebuild fails with "Invalid trust settings" or "errSecInternalComponent", the certificate may have custom trust overrides that break the chain:

# Check for custom trust settings
security dump-trust-settings 2>&1 | grep -A1 "Developer ID"

# If overrides exist, export the cert and remove them
security find-certificate -c "Developer ID Application" -p ~/Library/Keychains/login.keychain-db > /tmp/devid-cert.pem
security remove-trusted-cert /tmp/devid-cert.pem

Verify Certificate Chain

After fixing trust settings, verify the chain is intact:

codesign --deep --force --options runtime --sign "Developer ID Application: YOUR NAME (TEAM_ID)" /path/to/any.app 2>&1

The signing must show the chain: Developer ID Application → Developer ID Certification Authority → Apple Root CA.

Step 1: Archive

xcodebuild archive \
  -scheme "YourMacScheme" \
  -configuration Release \
  -archivePath /tmp/YourApp.xcarchive \
  -destination "generic/platform=macOS"

Step 2: Export with Developer ID

Create an ExportOptions plist for Developer ID distribution:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>method</key>
    <string>developer-id</string>
    <key>signingStyle</key>
    <string>automatic</string>
    <key>teamID</key>
    <string>YOUR_TEAM_ID</string>
</dict>
</plist>

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-notarization is a skill published in the GitHub repository hanamizuki/solopreneur (154 stars, last pushed 4d ago), licensed MIT. It adds 47 tokens to every session and 1,601 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). It is 100% identical to asc-notarization, differing in 30 lines, and is treated as a copy.
