Get engagement metrics for a specific tweet including likes, retweets, replies, and impressions
AI agents call get_tweet_metrics to retrieve information from Twitter Read without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The operation is read-only and returns aggregate data about tweet performance. Severity is low because misuse would only expose publicly available information without enabling harm.
