AI agents call x_get_tweet to retrieve information from X without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing tweet data by ID. It performs a query operation with no side effects—no data is created, modified, deleted, or executed. The action is purely informational retrieval, fitting the Read category. Severity is low because exposing tweet retrieval to an AI agent carries minimal risk; tweets are typically public information and reading them causes no harm.
From the tool's definition Tool name 'x_get_tweet' and description 'Get a single tweet by its ID' indicate retrieval of public tweet data without modification, deletion, or execution of side effects.
