Fetch a specific tweet by ID
AI agents call get_tweet_by_id 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 tweet data by ID without creating, modifying, deleting, or executing any operations. It is a pure read operation analogous to a database query or API fetch. The narrow scope (single tweet lookup) and read-only nature result in low severity and high confidence.
From the tool's definition Tool description states "Fetch a specific tweet by ID" — a retrieval operation with no modification or side effects.
