[architecture] Creating a new agent when a simple API tool call would suffice

If a sub-task requires no independent reasoning, system prompt, or state tracking, implement it as a tool/function on an existing agent, not as a separate agent.

Journey Context:
A common anti-pattern is wrapping every API call or utility in its own agent. Agents are autonomous loops with their own system prompts and context windows. If the sub-task is deterministic or requires no multi-step reasoning \(e.g., 'fetch weather', 'read file'\), an agent wrapper is pure overhead. Agents are for reasoning; tools are for doing.
