Feature Request: Enable Agent Teams on all plans

Request

Make Agent Teams feature (TeammateTool, SendMessage, spawnTeam) available on all plans, not just enterprise.

Current State

System prompt shows:

"Note: The 'Agent Teams' feature (TeammateTool, SendMessage, spawnTeam) is not available on this plan."

The feature exists but is gated behind plan tiers.

Use Cases

Complex multi-agent workflows need peer-to-peer coordination:

1. Parallel code review workflow:

• Planning agent creates task breakdown
• Multiple implementer agents work in parallel
• Each implementer hands off to dedicated reviewer
• Reviewers communicate findings to each other
• Final integration agent synthesizes results

2. Specialist agent collaboration:

• Frontend agent ↔ Backend agent coordinate API contracts
• Test agent validates both implementations
• Agents negotiate design decisions in real-time

3. Dynamic task delegation:

• Lead agent assesses complexity
• Spawns specialist sub-agents based on needs
• Sub-agents report back with results
• Lead agent adapts strategy based on feedback

Current Limitations

Without Agent Teams:

• ❌ Main agent must orchestrate everything
• ❌ No peer-to-peer communication
• ❌ Can't build self-organizing agent systems
• ❌ Limited to hub-and-spoke architecture

Current workaround: Spawn agents via Task tool, coordinate through shared state (files, task lists). But this is:

• Brittle (race conditions, state conflicts)
• Inefficient (polling for changes)
• Limited (no direct messaging)

Benefits of Enabling for All Users

1. Unlock advanced workflows - Users can build sophisticated multi-agent systems
2. Better UX - Agents that coordinate themselves vs manual orchestration
3. Showcase capabilities - Demonstrates Claude's multi-agent potential
4. Community innovation - Users will discover novel coordination patterns

Alternative

If full Agent Teams can't be enabled for all plans, provide lightweight coordination primitives:

• AgentMessage tool for peer-to-peer messaging
• Shared context/state management
• Event bus for agent coordination

Why This Matters

AI-native development needs AI-native coordination. Current limitation forces users back to traditional orchestration patterns instead of letting agents self-organize.

Environment

• Claude Code CLI version: 2.1.32
• Platform: macOS (Darwin 23.6.0)
• Plan: [Pro/Team - whatever the user has]
