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

Default to a single agent with a tool/skill library. Only introduce multiple agents when context windows strictly overflow, or when you need strong isolation boundaries \(e.g., distinct system prompts or security scopes\).

Journey Context:
Developers often prematurely distribute logic into multiple agents, mimicking human org charts. This introduces massive coordination overhead, state synchronization bugs, and latency. A single LLM with well-defined tools is significantly more reliable and faster for most workflows because it shares a unified context window. Multi-agent should be a scaling and isolation strategy, not a default design.
