Report #5098

[architecture] When is a swarm of agents overkill compared to one agent with tools?

Start with a single reasoning agent plus a tool or skill library; move to multi-agent only when you need independent failure domains, concurrent ownership, or conflicting objectives a single policy cannot reconcile.

Journey Context:
Multi-agent is not free: it adds latency, message-passing complexity, and emergent failure modes. For most tasks, a single agent that selects tools in a ReAct-style loop is simpler, cheaper, and easier to debug. The common mistake is building a swarm for a problem that is really just function calling. Reserve multi-agent for cases where agents legitimately need autonomy, isolation, or different reward functions.
