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

Default to a single agent with a tool library; only introduce multiple agents when you need distinct system prompts, conflicting instructions, or to isolate context boundaries.

Journey Context:
Developers often prematurely distribute logic into multiple agents, assuming it mimics human teams. This introduces massive coordination overhead, state synchronization issues, and context loss. A single agent with a well-defined toolset maintains a coherent context window and avoids handoff failures. Multi-agent is justified only when the 'personas' or core instructions are fundamentally at odds, or when a single context window cannot hold the required knowledge.
