--- name: multi-agent-patterns description: Design multi-agent architectures for complex tasks. Use when single-agent context limits are exceeded, when tasks decompose naturally into subtasks, or when specializing agents improves quality. --- # Multi-Agent Architecture Patterns for Claude Code Multi-agent architectures distribute work across multiple agent invocations, each with its own focused context. When designed well, this distribution enables capabilities beyond single-agent limits. When designed poorly, it introduces coordination overhead that negates benefits. The critical insight is that sub-agents exist primarily to isolate context, not to anthropomorphize role division. ## Core Concepts Multi-agent systems address single-agent context limitations through distribution. Three dominant patterns exist: supervisor/orchestrator for centralized control, peer-to-peer/swarm for flexible handoffs, and hierarchical for layered abstraction. The critical design principle is context isolation—sub-agents exist primarily to partition context rather than to simulate organizational roles. Effective multi-agent systems require explicit coordination protocols, consensus mechanisms that avoid sycophancy, and careful attention to failure modes including bottlenecks, divergence, and error propagation. ## Why Multi-Agent Architectures ### The Context Bottleneck Single agents face inherent ceilings in reasoning capability, context management, and tool coordination. Multi-agent architectures address these limitations by partitioning work across multiple context windows. ### The Parallelization Argument Many tasks contain parallelizable subtasks that a single agent must execute sequentially. Multi-agent architectures assign each subtask to a dedicated agent with a fresh context. ### The Specialization Argument Different tasks benefit from different agent configurations. Multi-agent architectures enable specialization without combinatorial explosion. ## Progressive Loading **L2 Content** (loaded when architectural patterns and implementation details needed): - See: [references/patterns.md](./references/patterns.md) **L3 Content** (loaded when memory systems and advanced coordination needed): - See: [references/memory-systems.md](./references/memory-systems.md)
