# Agent Teams > **Experimental**: Agent teams require `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` and may change between Claude Code versions. > **BREAKING (Claude Code 2.1.178)**: The explicit `TeamCreate` / `TeamDelete` tools were **removed**. Every session now has **one implicit team** when `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` is set — there is nothing to create or tear down. The `team_name` parameter is still **accepted but ignored** on the tools that took it (e.g. `Agent`), so older invocations don't error; omit it in new code. Coordination is otherwise unchanged: spawn teammates with the `Agent` tool, coordinate with `SendMessage`, and track work with `TaskCreate`/`TaskList`/`TaskUpdate`. For the worked setup examples, communication snippets, shutdown procedures, the worktree path-resolution recovery routine, and common dispatch patterns, see [REFERENCE.md](REFERENCE.md). ## When to Use This Skill | Use agent teams when... | Use subagents instead when... | |------------------------|------------------------------| | Multiple agents need to work in parallel | Tasks are sequential and interdependent | | Ongoing communication between agents is needed | One focused task produces one result | | Background tasks need progress reporting | Agent output feeds directly into next step | | Complex workflows benefit from task coordination | Simple, bounded, isolated execution | | Independent changes to the same codebase (with worktrees) | Context sharing is fine and efficient |...
