[architecture] When to use multiple agents versus a single agent with tools

Default to a single agent with a well-defined tool/skill library. Only introduce multiple agents if context window limits are hit, strict isolation of permissions is required, or parallel execution is necessary.

Journey Context:
Multi-agent systems introduce immense complexity in state synchronization, routing, and error propagation. Developers often over-architect by splitting agents by persona \(e.g., 'Researcher' vs 'Writer'\), but a single LLM with both tools can usually handle this seamlessly and more reliably. Multi-agent is only justified when the coordination overhead is outweighed by the need for isolated context or concurrent processing.
