The orchestrator pattern. Why effective agent systems use coordination layers rather than direct execution.
🎭 The Pattern
Effective agent systems separate planning from execution. An orchestrator manages state, delegates to subagents, and coordinates results. Anthropic's two-agent architecture exemplifies this: initializer + coding agent.
🔧 Why It Works
- State isolation: Each subagent gets clean context
- Parallel execution: Git worktree isolation enables concurrency
- Failure containment: One subagent failing doesn't pollute others
- Observability: Clear boundaries for tracing and debugging
📈 Production Evidence
OpenAI's 1M line experiment: three engineers, 3.5 PRs per day. The orchestration layer (worktrees, linters, progress tracking) enabled this throughput.
