/background[prompt]

Detaches the session to run as a background agent and frees the terminal. Optionally sends one more instruction first. Monitor with claude agents.

Best use

A 30-minute job: /bg write the results to report.md when done.

/bg

Do several things at once or run in the background/fork → /subtask → /background → /tasks → /batch

/agentsPrints a reminder to ask Claude to create or manage subagents, or to edit .claude/agents/ directly.
/batchOrchestrates large changes in parallel: researches the codebase, decomposes the work into 5–30 independent units and presents a plan; after approval, one background subagent per unit implements and tests it in its own worktree.
/forkCopies the conversation into a new background session while you keep working here.
/list-agentsLists subagents, teammates and other sessions Claude can message, with the name to use for each.
/stopStops the background session you're attached to; transcript and worktree are kept.
/subtaskSpawns a forked subagent that inherits the conversation and reports its result back here.
/tasksViews and manages background work in this session, including finished subagents.
/workflow-authoringLoads the reference for writing dynamic workflow scripts.
