macOS App Scaffold

Single entry point for macOS app scaffolding: create a new production-grade app, or add features to an existing one. Detects context and routes to the right flow. The two full flows are bundled as separate files in this skill: new-app.md (create from scratch) and enhance.md (add to an existing project), plus a templates/ folder.

Template files (.txt suffix)

Every file under templates/ has a trailing .txt appended only to satisfy the uploader's file-type filter — the real type is the inner extension. When you copy a template into the user's project, delete the trailing .txt (e.g. templates/agent/HelperMain.swift.txt → HelperMain.swift, templates/agent/LaunchAgent.plist.txt → LaunchAgent.plist, templates/agent/project.yml.snippet.txt → project.yml.snippet). Same rule for every file under templates/.

Routing Logic

Step 1: Detect Context

Scan the current directory for signs of an existing macOS project:

Look for ANY of these:
- project.yml          (XcodeGen)
- *.xcodeproj/         (Xcode project)
- Package.swift        (SPM executable)
- **/Sources/**App.swift
- **/Info.plist
- *.entitlements

Step 2: Route

If argument is provided:

• $ARGUMENTS starts with new → go to New App flow
• $ARGUMENTS starts with enhance or add → go to Enhance flow
• Anything else → treat as app name, go to New App flow with that name

If no argument and existing project detected:

Tell the user what you found, then ask:

Detected existing macOS project: {{AppName}}
  (project.yml, Sources/, .github/workflows/, ...)

What would you like to do?
  A) Add features to this project (CI/CD, auto-update, logging, etc.)
  B) Create a brand new app in a subdirectory

> 

If no argument and no project detected:

No macOS project found in the current directory.

What would you like to do?
  A) Create a new macOS app
  B) I'm in the wrong directory — let me navigate first

Step 3: Execute

For New App → Follow the complete flow defined in new-app.md:

1. Ask for app name + bundle ID (use argument if provided)
2. App archetype (Menu Bar / Windowed / Both)
3. Features checklist
4. CI/CD & Distribution
5. Generate everything

For Enhance → Follow the complete flow defined in enhance.md:

1. Analyze existing project
2. Show status dashboard (what exists vs what can be added)
3. Let user pick features
4. Surgically add selected features

Reference

The full instructions for each flow are in the bundled files new-app.md / enhance.md:

• New App flow → new-app.md
• Enhance flow → enhance.md

Read and follow that bundled file (new-app.md or enhance.md) completely when executing the chosen flow. Do not improvise — use the templates and patterns defined there.

Full flows (bundled files)

• New App → read and follow new-app.md (bundled with this skill) completely.
• Enhance → read and follow enhance.md (bundled with this skill) completely.
• Reusable code/config templates are under templates/ (strip the trailing .txt on copy, per the note above).
