[architecture] Over-engineering multi-agent systems when a single agent with tools suffices

Default to a single agent with a tool/skill library; only introduce multiple agents if you need strict context isolation, parallel execution, or distinct system prompts that conflict.

Journey Context:
The hype around multi-agent systems leads developers to spawn agents for every sub-task. Every agent boundary introduces a context loss penalty and a communication failure point. A single LLM with a well-defined tool interface maintains coherent state much better. Multi-agent is only justified when context windows overflow, when security/isolation is needed, or for true parallel processing of independent tasks.
