[architecture] When to use multiple agents vs a single agent with tools
Default to a single agent with a tool library. Only introduce multiple agents if you need parallel execution, strict permission isolation, or to avoid context window limits.
Journey Context:
Multi-agent systems introduce severe coordination overhead, context synchronization issues, and error cascades. A single agent maintains a unified context, eliminating the 'telephone game' where context is lost or mutated between handoffs. The tradeoff is that a single agent can suffer from tool-choice confusion if the tool library grows too large, and it cannot execute independent tasks in parallel.
