Can I see who has already signed a document?

Yes. Use the `get_document` tool with the specific Document ID. The agent will return the list of participants and their respective signing status.

What is an audit log in Modusign?

An audit log records every action taken on a document, including when it was sent, opened, and signed, providing legal proof of the transaction. Use the `get_audit_logs` tool to retrieve this history.

How do I reuse my existing contract templates?

Use the `list_templates` tool to find the Template ID you need, and then provide that ID to the `create_document_from_template` tool along with the signer's details.
