Agents

AI agent reasoning and tool selection tests planning, tool choice, and self-diagnosis capabilities. These skills are crucial for autonomous ticket triage systems and complex agent workflows where models must decide which tools to use, plan multi-step processes, and diagnose when things go wrong. This represents some of the most challenging tasks as they require open-ended reasoning and decision-making.

Input

You must find today's date so you can time-stamp a help-desk note. Which tool do you call and with what parameters?

Expected output

Use the **calendar** tool with parameters {"action": "get_current_date"}.

Model output

Reasoning: To time-stamp a help-desk note, I need to get today's date. Looking at the available tools, I can see there's a 'calendar' tool that has a method called 'get_current_date'. According to the schema, this method requires only the 'action' parameter set to 'get_current_date' with no additional parameters needed. This will return the current date that can be used to time-stamp the help-desk note.

Response: To find today's date for time-stamping a help-desk note, I would call the **calendar** tool with the following parameters:

```json
{
  "action": "get_current_date"
}
```

This call requires no additional parameters beyond specifying the action. The calendar tool's `get_current_date` method will return the current date in ISO-8601 format, which can then be used to time-stamp the help-desk note.
