[synthesis] When should an AI agent stop and use a tool vs. answering directly, and how to prevent hallucinated tool arguments?

Force the model to output a 'thought' block before every tool call or final answer. The thought block should assess if it has sufficient information; if not, it must select a tool. Do not allow tool calls without a preceding reasoning step.

Journey Context:
Naive agents just call tools based on keywords. This leads to unnecessary API calls or hallucinated parameters. By forcing explicit reasoning \(Chain of Thought\) \*before\* the tool call, the model can decide it doesn't need the tool, or formulate better query parameters.
