[architecture] Prematurely decomposing a workflow into multiple specialized agents when a single agent with a skill library would suffice

Default to a single-agent-with-tools architecture. Only introduce a second agent if there is a strict isolation boundary \(e.g., distinct permissions, fundamentally different context windows, or independent execution loops\) that makes single-agent execution impossible or unsafe.

Journey Context:
Developers often map multi-agent systems to human organizational charts, assuming specialized roles improve performance. In LLMs, inter-agent communication requires serialization/deserialization of context, introducing latency, token cost, and information loss. A single agent maintains a unified context window, eliminating handoff errors. The tradeoff is that a single agent's context window can get cluttered, but tool-use keeps the active reasoning focused.
