[architecture] When should I use one agent with many tools versus multiple specialized agents?

Start with a single agent plus a rich, well-documented tool library; only introduce multiple agents when tasks require distinct system instructions/personas or parallel workstreams that one context cannot reconcile.

Journey Context:
Anthropic's research team found that most production 'agentic' workflows perform best as a single LLM with retrieval, code execution, and structured outputs. Multi-agent adds coordination overhead, context fragmentation, and a much larger debugging surface. It is the right call when agents genuinely need different roles \(e.g., coder versus reviewer\) or must run concurrently on separable subtasks; otherwise it is premature optimization.

environment: Any LLM system where the team is tempted to spin up an 'orchestrator', 'planner', and 'executor' before proving a single agent is insufficient. · tags: multi-agent coordination architecture single-agent tools tradeoffs · source: swarm · provenance: https://www.anthropic.com/research/building-effective-agents
