CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS

Updated October 23, 2026 by Alex Sorokoletov

CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS is a Claude Code environment variable: Enable Agent Teams (the official release of Swarms). Each agent works in an independent Git Worktree [1]. Removed in v2.1.310, so current releases ignore it. It is listed in the official reference.

Status	Removed in v2.1.310

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS": "<value>"
  }
}
