List time tracking categories (or one by ID), including cost_per_hour.
AI agents call list_time_tracking_categories to retrieve information from InvGate Service Desk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It has no side effects, does not execute operations, and does not modify or delete data. The queried cost information is reference data, not a financial transaction. Classification as Read is appropriate.
From the tool's definition Tool name 'list_time_tracking_categories' and description 'List time tracking categories' clearly indicate a retrieval operation with no modification capability. The inclusion of 'cost_per_hour' is metadata being queried, not financial transactions.
