[architecture] When to use multi-agent vs single-agent with tools
Default to a single agent with a tool/skill library. Only introduce multiple agents if you need distinct system prompts, isolated memory scopes, or to bypass context window limits.
Journey Context:
Multi-agent setups introduce massive overhead in state synchronization, message passing, and routing logic. LLMs are highly capable of selecting the right tool within a single context. Multi-agent is only justified when the persona or authority must be strictly isolated \(e.g., a writer vs. a reviewer with conflicting goals\) or when context limits are breached. Otherwise, the coordination cost exceeds the cognitive benefit.
