asc-notarization SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

asc-notarization from the-artificer-of-ciphers-llc/skills-from-the-artificer is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/asc-notarization@git:20261014.5f864de

Pins git:20261014.5f864de in mdr.lock. Pin the fingerprint instead.

Archive, export, and notarize macOS apps using xcodebuild and asc. Use when you need to prepare a macOS app for distribution outside the App Store with Developer ID signing and Apple notarization.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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:

```bash
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:

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

# If overrides exist, export the cert and remove them
…

How to install

The exact contents, by fingerprint

mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/asc-notarization@sha256:e719161403467be2

The line at the top of this page pins the label git:20261014.5f864de, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
