Build any Mac app

Find where the user is on the path below, then call the Skill tool with the skill for that step. One skill per call.

idea -> research -> clone (optional) -> app-brief -> user-stories -> new-mac-app
     -> mac-design + design-system + app-icon -> improve-loop (ux, code, design, verify, commit) -> repeat

Pick the app's name first (app-brief, step 1) and create <parent>/<AppName>/docs/ before research, so every skill writes into the same folder. Design comes right after the scaffold: tokens from the first view, and the real icon in every snapshot.

Plan

The user has	Skill
A vague idea, or asks "what should I build"	research, then app-brief
An app they want to replace or rebuild	clone
A brief or a screen index, no backlog	user-stories
A spec from BAMA's specs/ folder	app-brief (it copies the spec)

Build

The user wants to	Skill
Start a new project	new-mac-app
Write or fix Swift and SwiftUI code	swift-swiftui
Hook into macOS: hotkeys, menu bar, windows, screen capture, Shortcuts	os-integrations
Make it fast: hangs, stutter, GPU, video, memory	performance
Let Claude Code, Codex, or scripts drive the app: a CLI, an MCP server	agent-cli
Refactor, clean up, or check the code as it grows	improve-architecture

Design

The user wants to	Skill
Decide how a feature works and what it says: names, flow, modals, accessibility	ux-design
Make it look and feel like a Mac app	mac-design
An accent or brand color, a color picker, tokens	design-system
Their own parts and feel, not Apple's: buttons, rows, sidebar, icons	design-kit
The look of an app they name, or screenshots of one	design-from-app
One set of colors, radii, motion, and controls for the whole app	design-system
Fix spacing and alignment, or check the layout on the grid	layout-grid
An app icon	app-icon

Ship

The user wants to	Skill
Build it and look at every page	build-and-verify
Tests, a self-test, or an agent that drives the running app	test-mac-app
Work through the backlog on its own	improve-loop

Done when

You named the step, called its skill, and told the user which skill comes after it.
