find_similar_news
AI agents call find_similar_news to retrieve information from TrendRadar without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to search or retrieve news items similar to a query or reference item. This is a read operation—it queries and returns data without modifying, deleting, or executing external actions. The broader context of a news aggregation and analysis platform confirms a read-only classification. Severity is low because misuse would at worst return unwanted news results, not compromise systems or data integrity.
