[architecture] Over-engineering a multi-agent system when a single agent with a skill library suffices

Default to a single agent with tools/skills; only introduce multiple agents if you need strict context isolation, parallel execution, or entirely different system prompts/personas.

Journey Context:
Developers often assume complex tasks require multiple agents, but multi-agent systems introduce orchestration overhead, context handoff failures, and cascading hallucinations. A single LLM is highly capable of selecting tools. Multi-agent is only justified when the context window cannot hold the required diverse personas or when tasks must run concurrently.
