Think Tool
Step-by-step reasoning scratchpad for planning and decision-making.
Overview
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.
This is a lightweight tool with no side effects. It is most useful for models that lack built-in reasoning or thinking capabilities (e.g., smaller or older models). For models that already support native thinking — such as Claude with extended thinking, OpenAI o-series, or Gemini with a thinking budget — this tool is unnecessary since the model can reason internally.
Configuration
toolsets:
- type: think
No configuration options.
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.
