A workflow for signing, checking with Apple, and packaging a macOS app as a .pkg installer for Jamf Self Service deployment.

It is for preparing a built .app for organizational Mac deployment by signing it, submitting it for Apple notarization, attaching the approval, building a .pkg, and verifying it.

It gathers the required Apple certificates and credentials into a defined release process, including checks that the package is ready to distribute.

psd-sign — Skill for Claude Code by psd401

Install

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.

Any agent

npx skills add psd401/psd-claude-plugins --skill psd-sign

Clone the repo

git clone --depth 1 https://github.com/psd401/psd-claude-plugins

Made for: Claude Code.

Or install psd-coding-system, the plugin that ships this one along with the rest of its 9 skills, 5 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00073	$0.01418
Opus 5	$0.00036	$0.00709
Sonnet 5	$0.00015	$0.00284
Haiku 4.5	$0.00007	$0.00142

Security

Grade C, and why

psd-sign scanned grade C with 1 finding 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 6d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

PSD macOS App Signing & Packaging

Sign, notarize, and package a macOS .app into a .pkg for deployment via Jamf Self Service.

PSD Constants

These are embedded in the workflow and should not need to change unless PSD's Apple Developer account changes.

Team ID: 87DL7L9GU6
App Signing Identity: Developer ID Application: Peninsula School District (87DL7L9GU6)
Installer Signing Identity: Developer ID Installer: Peninsula School District (87DL7L9GU6)

Prerequisites

macOS with Xcode Command Line Tools installed
PSD Developer ID certificates installed on the machine (both Application and Installer)
An Apple ID that is a member of the PSD Apple Developer account
An app-specific password for that Apple ID (generate at https://appleid.apple.com), or a stored notarytool keychain profile (preferred — see Step 0)
A built .app bundle ready for signing

Workflow

When invoked, collect the following from the user before proceeding:

App path — full path to the .app bundle (may be provided as an argument)
Credentials — a notarytool keychain profile name if one exists (see Step 0); otherwise the @psd401.net Apple ID + app-specific password. SECURITY: never log, echo, or store the password
Version number — semver string for the package (e.g., 1.0.0)
Bundle identifier — defaults to net.psd401.<appname-lowercase>

Confirm the configuration with the user, then run each step sequentially. Stop immediately on any failure and report the error.

Step 0 (one-time, optional but preferred): Store notarization credentials in the keychain

A stored profile keeps the app-specific password out of process listings and shell history. Offer this on first use; afterwards every notarytool call uses --keychain-profile psd-notary instead of --apple-id/--password.

xcrun notarytool store-credentials psd-notary \
  --apple-id "$APPLE_ID" \
  --team-id 87DL7L9GU6
# prompts interactively for the app-specific password — have the user run this themselves

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.

psd-sign is a skill published in the GitHub repository psd401/psd-claude-plugins (2 stars, last pushed 6d ago), licensed MIT. It adds 73 tokens to every session and 1,418 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
