Spawn as many as you need. Detach, come back tomorrow, and everything is still there.</p> <ul> <li>Isolated - Every task runs in its own branch and worktree. Agents can't collide or overwrite each other.</li> <li>Persistent - tmux keeps agents alive when you close your terminal. Worktrees survive reboots. ag resume rebuilds everything from disk. If a tmux session dies, ag attempts to resume conversations for claude and codex.</li> <li>Stateless - Git worktrees are the state. No databases, no config files, no daemon. If tmux disappears, your work is still intact.</li> <li>Combined API - One CLI tool - ag spawn, ag kill, ag open, ag rm, ag ls. Nothing more.</li> </ul> ai bash claude opensource
