AI agents call get_popular_tags to retrieve information from Looba without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval function that queries and returns tag statistics. It performs no write, delete, execute, or financial operations. The low severity reflects minimal blast radius: misuse would only result in retrieving tag information that is already public on the community platform.
