What are Tools?
Tools connect your assistant to external services. When a tool step executes:- The assistant gathers required inputs
- The tool calls the external service
- Results are written to live variables
- The step condition evaluates success or failure

Tools accept two types of inputs:| Input Type | Description |
|---|---|
| Manual Inputs | Values you configure when setting up the tool step |

Tool Outputs
Tools write results to live variables that can be used in subsequent steps. All tools return aresult boolean indicating success or failure.
See Variables for the full list of available variables.
