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

Default to a single agent with a tool library. Only split into multiple agents if you hit context window limits or need fundamentally conflicting system prompts.

Journey Context:
Multi-agent systems introduce severe coordination overhead, context loss during handoffs, and routing failures. A single agent maintains a unified mental model of the task. Splitting agents is only justified when the context required for one persona \(e.g., a strict code reviewer\) directly conflicts with another \(e.g., a creative writer\), or when the combined context exceeds token limits.
