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

Use a single agent with a tool/skill library unless you have distinct cognitive architectures, isolated memory/state, or need parallel execution of independent tasks. Multi-agent adds coordination overhead \(context passing, routing failures\).

Journey Context:
Developers often think 'different tasks = different agents', but LLMs are general-purpose. Routing context between agents causes information loss and latency. A single agent with well-defined tools maintains full context. Multi-agent is only justified when context windows are exceeded by distinct domains, or when tasks must run in parallel without blocking the main thread.
