[architecture] Over-decomposing tasks into multiple agents when a single agent with a tool library suffices

Default to a single agent with a well-defined skill/tool library; only introduce multiple agents if you need isolated context windows, distinct system prompts, or parallel execution.

Journey Context:
Multi-agent setups introduce coordination overhead, context-passing loss, and cascading failure points. A single agent maintains a unified mental model of the task. The tradeoff is that a single agent's context window can get cluttered, leading to forgotten instructions. Multi-agent is only the right call when context limits are hit or when fundamentally different personas \(e.g., planner vs. coder\) are needed to avoid prompt interference.
