Report #12650

[architecture] Spawning multiple agents for a task that could be handled by a single agent with a tool library, leading to excessive context switching and coordination overhead

Default to a single-agent-with-tools architecture. Only introduce multiple agents if there is a clear need for isolated context windows, divergent system prompts, or parallel execution.

Journey Context:
The multi-agent buzzword makes developers spawn swarms for everything. However, a single strong model with a well-defined tool suite often outperforms a fragmented system. Coordination overhead \(routing, message passing, state sync\) consumes more tokens and introduces more failure points than the task warrants. Tradeoff: Single agent hits context window limits on massive tasks. Multi-agent is right when you need distinct personas or parallel processing.
