Claude Code Agent Teams: Hierarchical Orchestration
With the introduction of Opus 4.6 as a research preview, Anthropic rolled out Claude Code Agent Teams. This framework moves past the single-agent bottleneck by allowing developers to instantiate parallel Claude instances working collaboratively.
The architecture consists of a "Team Lead" agent and specialized "Teammate" agents. They share a synchronized task list, communicate via direct internal messaging, and expose explicit lifecycle hooks so developers can pause, inspect, or terminate the run.
// Example: Conceptual Agent Team Configuration
{
"team_name": "backend_refactor_squad",
"lead": {
"model": "claude-3-opus-20240229", // Upgrading to Opus 4.6
"role": "Orchestrator and Code Reviewer"
},
"teammates": [
{
"id": "db_specialist",
"role": "Writes SQL migrations and tests",
"tools": ["psql_exec", "fs_write"]
},
{
"id": "sec_auditor",
"role": "Audits generated code for OWASP vulnerabilities",
"tools": ["semgrep_scan"]
}
],
"shared_context": {
"workspace": "/tmp/repo_clone",
"strict_mode": true
}
}
Trade-offs vs. Single Agent:
While a single agent suffers from context degradation and "distraction" when given too many tools, an Agent Team isolates context and tool sets per teammate. The trade-off is increased token consumption due to inter-agent messaging and coordination overhead.
