Anthropic shipped multi-agent orchestration for Claude Code. Multiple sessions working together on the same codebase.
how it works:
[Lead] → coordinates, assigns tasks
↓
[Teammate A] ←→ [Teammate B] ←→ [Teammate C]
(can communicate directly)
vs subagents:
Subagents report back to main only. Agent Teams talk to each other.
(comparison table, see on a wider screen)
| | Subagents | Agent Teams |
| ------------- | ------------------------ | --------------------------------- |
| communication | report back to main only | message each other directly |
| coordination | main controls everything | shared task list, self-organizing |
| tokens | lower | higher (each = separate session) |
| use when | focused tasks | complex work requiring discussion |
best use cases:
• research from multiple angles
• parallel module development
• debugging with competing hypotheses
• frontend + backend + tests simultaneously
key features:
• delegate mode — lead only coordinates, doesn't code
• plan approval — teammate plans, lead approves before implementation
• split panes — each teammate in its own pane
• shared task list with dependencies
enable:
{"env": {"CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS": "1"}}
Multi-agent orchestration out of the box. What OpenAI Frontier promises for enterprise, Claude Code now does locally for individual developers.
