[architecture] When to use single-agent-plus-tools vs. multiple agents

Default to a single agent with a tool library. Only introduce multiple agents when you need isolated system prompts, parallel execution, or distinct security boundaries.

Journey Context:
Developers often over-decompose tasks into multi-agent systems, which introduces routing overhead, context loss during handoffs, and duplicated token costs \(each agent needs its own system prompt and context\). A single agent maintains a unified context window and avoids handoff failures. Multi-agent is only justified when instructions fundamentally conflict \(e.g., writer vs. critic\) or tasks can run in parallel.
