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

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
