AI agents call get_quota to retrieve information from Baidu Pan without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only queries storage quota statistics. It performs a read-only operation that returns metadata about storage usage. There are no side effects, data modifications, code execution, or financial implications. This is a simple information retrieval operation, fitting the 'Read' category with low severity due to minimal risk even if misused by an AI agent.
From the tool's definition Tool name is 'get_quota' and description translates to 'Get Baidu Netdisk storage quota (used/total)'. This retrieves quota information without modifying or deleting any data.
