[cost\_intel] Over-decomposing tasks into multi-agent workflows where each agent has its own system prompt and context

Keep simple, deterministic tasks in a single prompt or traditional code pipeline; only use multi-agent setups when tasks require independent reasoning or tool use.

Journey Context:
A 3-agent workflow where each agent gets a 5k system prompt and 10k context costs 3x the input tokens compared to a single agent. If the sub-tasks are deterministic \(e.g., extract, translate, format\), a single prompt with clear sections or a standard Python script is 10x cheaper and faster. Multi-agent is only justified when context windows overflow or independent tool-use loops are strictly necessary.
