The think tool is a reasoning scratchpad that lets agents think step-by-step before acting. The agent can write its thoughts without producing visible output to the user — ideal for planning complex tasks, breaking down problems, and reasoning through multi-step solutions.

💡 When to use
-
Include the think tool in every agent. It adds minimal overhead while significantly improving reasoning quality on complex tasks.
+
Use the think tool with models that don't have native reasoning capabilities. If your model already supports a thinking budget, you likely don't need this tool.
