AI agents call read_section to retrieve information from Doc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves structured data from document sections without creating, modifying, deleting, or executing any operations. It is a pure read operation with no side effects, fitting the 'Read' category with low severity and high confidence.
From the tool's definition Tool name is 'read_section' and description states '读取整个章节的所有字段数据' (reads all field data from an entire section). The verb '读取' (read) and the context of retrieving section data without modification indicators confirm this is a retrieval operation.
