AI agents call search_titles to retrieve information from Wikimedia without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search query against Wikimedia page titles and returns matching suggestions with descriptions. It has no capability to modify, delete, or execute operations—it purely retrieves and presents existing data. The parameters (query, limit, project) are all input filters for the search, with no destructive or state-changing capabilities. This is a classic Read operation with minimal security risk.
