The model can run subagents in the background (Task with run_in_background: true) and keep working. Each report is delivered when that agent finishes: mid-turn, or by starting a new turn if the model is idle. With -p, Chanto waits for background agents before exiting.
isolation: "worktree" gives a subagent its own git worktree and branch (.chanto/worktrees/<id>, branch chanto/<id>), so several agents can edit in parallel without touching your checkout. The report says what changed on the branch, and a worktree with no changes is removed. resume: "<id>" sends a finished agent follow-up instructions, and it keeps its context. /tasks lists background agents and /tasks stop <id> cancels one.
