There are now several ways to run Claude Code work in parallel.

Subagents keep specialized work inside one session, with separate context windows and summary handoff back to the main conversation. Agent View, opened with claude agents, lets you dispatch and monitor independent background sessions.

There are also slash commands for different levels of separation. /background detaches the current session, and /tasks lets you inspect running work. /fork sends a side task to a background subagent that inherits the current conversation. /branch lets you try a different conversation path yourself and return later with /resume.

Agent teams and dynamic workflows are for larger coordinated runs, where multiple agents work on related tasks and cross-check each other. For big changes, the bundled /batch skill can split work into worktree-isolated subagents. The pattern is the same: isolate context, give each worker a narrow job, and reconcile the result carefully.
