Get a user\
AI agents call get_followers to retrieve information from Agent Twitter Client without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves follower information about a user on Twitter. It performs a query operation that does not create, modify, delete, or execute any actions. The read-only nature and lack of side effects classify it as a Read category risk with low severity, as exposure only allows passive information retrieval about public or authorized user follower lists.
From the tool's definition Tool name 'get_followers' and verb 'Get' indicate data retrieval. Description states 'Get a user' (likely followers of a user), which is a read-only query operation with no side effects.
