AI agents call neptime_get_categories to retrieve information from Neptime without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries categorical metadata from the Neptime platform without modifying, deleting, or executing any operations. It is a simple data fetch with no reversible or irreversible changes, financial impact, or code execution. It poses minimal risk as it only exposes public or user-accessible category information.
From the tool's definition Tool name 'neptime_get_categories' and description 'Get all video categories' with return of read-only metadata (id, name, video count) indicates a retrieval operation with no side effects.
