From the README

dev-3.0

  A Kanban board where every card is a live AI coding agent.
  Each task gets its own git worktree, its own terminal and its own agent — so a dozen of them
  can run at the same time without ever touching each other's files.

  Every card is a real git worktree, a real terminal and a real branch.

What using it looks like
Write a task → get a worktree → an agent works in it → you watch → you review → it merges

Six steps. You write the first one and approve the last; the middle four happen on the board.

1. Write a task, pick who does it

You describe the work and choose the agent. Claude Code, Codex, Gemini, Cursor Agent, opencode
— or several at once, each in its own pane of the same task.

2. dev-3.0 builds the sandbox

A fresh git worktree off your base branch, a tmux session inside it, your per-project
setup script, and — if you asked for them — free ports reserved for that task's dev server.
Heavy directories like node_modules or .venv are copy-on-write cloned, so the sandbox costs
near-zero disk and appears instantly.

Nothing the agent does can collide with another task. That is the whole reason ten of them can
run at once.

3. Watch without opening anything

Hover a card and the live terminal comes to you. No clicking in, no losing your place on the
board.

The card also carries the state you actually need at a glance: which agent and model, priority,
memory use, a bell when the agent wants you, and a red badge when it asked a question.

4. Several agents on one task, side by side

Split panes in the same worktree — one writes, one reviews, one runs the tests. Or three
independent variants of the same task on separate…
