Get title/preview/cover of an X Article embedded in a tweet.
AI agents call get_article_preview to retrieve information from Twikit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (title, preview, cover image) from an embedded article in a tweet. It performs a read-only query operation without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an agent could retrieve article previews that might be private or sensitive, but no data is altered and no external operations are triggered.
From the tool's definition Tool name 'get_article_preview' and description 'Get title/preview/cover of an X Article embedded in a tweet' indicate a retrieval operation with no side effects.
