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

Default to a single agent with a skill/tool library. Only introduce multiple agents if you hit context window limits, need strict capability isolation \(security/compliance\), or have highly distinct system prompts that conflict.

Journey Context:
Developers often over-architect by assigning every task to a separate agent, thinking it mimics human organizations. This introduces massive orchestration overhead, state synchronization failures, and context loss. A single LLM with a unified context and diverse tools is far more reliable for most tasks. Multi-agent is a tradeoff: you gain isolated context windows and specialized system prompts, but you lose shared state and pay a high latency/token cost for inter-agent communication.
