Swarm Mode, officially called Agent Teams, is a multi-agent orchestration feature in 📝Claude Code (Anthropic) that transforms Claude from a single AI assistant into a coordinated team system. Introduced with Opus 4.6 and enabled via the CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 environment variable, Agent Teams uses TeammateTool to coordinate a team lead with multiple teammate agents working in parallel. The system employs a Task framework where agents can claim, work on, and complete tasks independently while maintaining team coherence through the lead agent's oversight.
