What is macos-app-scaffold-new?

A starter-project generator for new macOS apps, using SwiftUI and XcodeGen to create the project files.

Use it to create a new app with GitHub Actions automation, code signing, notarization, automatic updates, and SwiftUI starter code.

It removes much of the setup work involved in creating a shippable macOS app, including builds, signing, updates, and release publishing.

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 XueshiQiao/macos-app-scaffold --skill macos-app-scaffold-new

Clone the repo

git clone --depth 1 https://github.com/XueshiQiao/macos-app-scaffold

Made for: Claude Code.

Or install macos-app-scaffold, the plugin that ships this one along with the rest of its 3 skills.

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	$0.00039	$0.15987
Opus 5	$0.00019	$0.07994
Sonnet 5	$0.00008	$0.03197
Haiku 4.5	$0.00004	$0.01599

Security

Grade C, and why

macos-app-scaffold-new 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 12d 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.

If the user wants the project locally without creating a GitHub repo yet, use `gh repo clone` + delete-remote pattern, or `git clone --depth=1` + `rm -rf .git && git init`.

How it starts

The opening of the file, as written. The whole thing — 1,580 lines — stays where its author put it; the contents beside it link to each section on GitHub.

New macOS App Scaffold

Create a production-ready macOS application project. Walk the user through interactive choices, then generate all files.

Arguments

$ARGUMENTS[0] = App name (e.g., MyApp)
$ARGUMENTS[1] = Bundle ID (e.g., me.xueshi.myapp)

If arguments are missing, ask the user before proceeding.

Interactive Flow

Ask questions in this exact order. Present each step clearly with numbered/lettered options and defaults in bold. Wait for user response before proceeding to the next step. You may combine steps 3 and 4 into a single message if appropriate, presenting them as a checklist.

Step 0: Generation strategy — template repo vs from-scratch (ask first)

Ask the user:

I can scaffold this two ways: A) From the template repo (default, fastest, fewest tokens) — clones XueshiQiao/macos-app-starter and applies a small rename + customization diff. Best when your needs match the template's flavor (Menu Bar + Window hybrid, Sparkle, signed CI, full i18n, MIT, no sandbox). B) From scratch — generates every file from the templates in this skill. Best when your archetype/feature mix is far from the template (e.g., Menu Bar only, no Sparkle, sandboxed, no localization).

Which would you like? (default A)

If the user picks A (template), follow "Generation Path A: Template Clone" below — most steps simplify to "delete the parts you don't need" and "rename".

If the user picks B (from-scratch), follow the existing Step 1 → Step 5 flow and the Generation Rules section.

The template's exact flavor (so you can judge fit on the user's behalf):

Archetype: Menu Bar + Window (hybrid)
Sandbox: No
SPM deps: Sparkle, KeyboardShortcuts, Aptabase
Auto-update: Sparkle
Background helper: None
Languages: English + Simplified Chinese
License: MIT
Cask: Draft (template_only topology)
CI/CD: Two-track signed/unsigned (workflow file is in the template repo)

If 5+ of these don't match what the user wants, recommend B.

What ships with it

26 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.
