Report #2359
[architecture] Over-engineering multi-agent systems when a single agent with tools suffices
Default to a single agent with a well-defined tool library; only split into multiple agents if context limits are hit, distinct permission boundaries are required, or orthogonal cognitive loops \(e.g., planner vs. executor\) are necessary.
Journey Context:
Multi-agent introduces latency, handoff errors, and context fragmentation. Developers often treat agents as microservices, but LLMs suffer from context loss during handoffs. A single agent maintains unified working memory. The tradeoff is that a single agent's context window can fill up, and tool selection degrades with too many tools. Split when tool count or context exceeds reliable retrieval limits.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
