They work on their own branches. You merge what you want.
Each employee is a Claude Code session with a name, a role, a folder of their own, and their own git checkout. Crew staffs the repository; Nodal supervises the work.
Not a convention, a git worktree. Each one sits on crew/<name> with its own working directory, so four agents cannot overwrite each other's files or fight over index.lock. Nothing reaches your branches until you merge, and the app never merges for you.
Every employee is a session of the Claude Code CLI already installed on your Mac, signed in as you. The app holds no credentials, proxies nothing, and cannot bill you.
Crew is free for everyone and runs on the Claude Code session already installed on your machine. Nodal supervises the work; Crew decides who does it.
