See an app you like. Rebuild it as your own native Mac app.

Quick start

npx skills@latest add daveebbelaar/bama

Then ask your agent:

Clone my to-do app as a native Mac app.
Screenshot every screen, write the user stories, and build milestone 1.

Not sure where to start? Type /bama. It looks at your project and picks the next skill.

How it works

1. Clone

Your agent opens the app you like and screenshots every screen. It writes a screen index.

2. Plan

It turns the screens into user stories with checkable acceptance criteria, in milestones.

3. Build

It builds one story per commit. Before each commit it snapshots every page in light and dark mode and runs the tests.

Skills

Specs

Not sure what to build? specs/ has 12 build plans for small Mac apps: a window snapper, a window switcher, a launcher, clipboard history, screenshots, a screen recorder, and more. I took them apart from Onyx, my own menu bar app. Copy one into an empty folder and tell your agent:

Build the app in window-snapper.md with BAMA.

Install

Pick one route per agent. Two routes install every skill twice.

/plugin marketplace add daveebbelaar/bama
/plugin install bama@bama

codex plugin marketplace add daveebbelaar/bama
codex plugin add bama@bama

Uses skills.sh. Install all skills, or one with --skill.

npx skills@latest add daveebbelaar/bama -a <agent>
npx skills@latest add daveebbelaar/bama --skill=clone

git clone https://github.com/daveebbelaar/bama.git
bama/scripts/link-skills.sh       # links every skill into ~/.claude/skills and ~/.agents/skills

Requirements

• macOS 26 or later
• Xcode 26 or later, for the Swift 6.2 toolchain (you never open it)
• An agent that supports skills: Claude Code, Codex, Cursor, Gemini CLI
• For clone on native apps: computer use (Claude Pro or Max)

Credits

• The idea and the "any" promise come from REA: Reverse Engineer Anything by morluto. REA showed that an agent can reverse engineer any app. BAMA takes that idea to the Mac.
• Skill format and writing rules follow Matt Pocock's skills and his writing-for-agents skill.
• Works well with SwiftUI Pro by Paul Hudson and SwiftUI Expert by Antoine van der Lee.
