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

Default to a single agent with well-defined tools. Only introduce multiple agents if you require parallel execution, distinct system prompts/weights, or strict capability isolation.

Journey Context:
Developers often map organizational charts to agent architectures \(e.g., Researcher, Writer, Editor agents\). This introduces massive latency, context synchronization overhead, and routing failures. A single strong model with tool-calling is usually faster, cheaper, and more reliable for sequential tasks because it avoids inter-agent communication loss.
