Agent Teams

Coordinate multiple Claude Code instances as a team with shared task lists, inter-agent messaging, and independent context windows. Fundamentally different from subagents (Task tool): teammates communicate directly with each other, not just back to the caller.

When to Use Agent Teams vs Subagents

Does the work require inter-agent communication?
├── No → Use subagents (Task tool)
│   ├── Focused tasks where only the result matters
│   ├── Research/verification that reports back
│   └── Lower token cost (results summarized to main context)
└── Yes → Use Agent Teams
    ├── Teammates need to share findings mid-task
    ├── Adversarial debate / competing hypotheses
    ├── Self-organizing work from shared task list
    └── Complex coordination across 3+ parallel workers
