Can I see my team's vacation balances through my agent?

Yes. Use the `get_leave_balances` tool with a specific User ID. Your agent will retrieve the active leave balances representing vacation arrays globally, including different types of absences (e.g. Paid Leave, RTT) managed in Timmi.

How do I check the individual claims within an expense report?

The `list_expense_claims` tool allows your agent to extract absolute bounded individual claims for a specific Expense Report ID. You'll see precise dates, amounts, and native currency payloads for each item in the report.

Can my agent list all company departments defined in Lucca?

Absolutely. Use the `list_departments` tool to retrieve the strict hierarchical organizational units. Your agent will report the department names and their hierarchy, helping you understand the company's structural boundaries.
