[synthesis] Agent uses a tool for a task it could have answered from its internal knowledge, introducing latency and potential error from the tool's API

Implement a 'tool necessity check' step where the agent must explicitly justify why internal knowledge is insufficient before invoking an external tool.

Journey Context:
When agents are given a suite of tools, they exhibit a bias towards using them, even for trivial queries \(e.g., using a calculator tool for 2\+2\). This increases latency, cost, and the chance of API errors or context pollution from the tool response. The chain of reasoning is 'I have a tool, therefore I should use it.' Requiring an explicit justification flips this to 'I will use my knowledge unless the tool is strictly necessary,' optimizing the tradeoff between accuracy and efficiency.
