Can I check the value of a sales opportunity using the agent?

Yes! Use the `get_opportunity_details` tool with the Opportunity ID. Your agent will fetch the detailed metadata, which includes the value amount and currency from Capsule CRM.

How do I list all the people in my CRM?

Simply ask the agent to `list_contacts`. It will retrieve the list of all parties (people and organizations) from your Capsule account, including their names and primary details.

Does the integration allow creating a new task?

Yes. Use the `create_task` action and provide the description. You can also optionally specify a due date. The task will be added to your Capsule account instantly.
