AI agents call lucille_my_stats to retrieve information from Lucille without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns player statistics. It has no capability to modify game state, execute actions, transfer assets, or trigger external operations. The verb 'Check' and the list of read-only metrics (stats, scores, counts) confirm this is a pure data retrieval operation. Low blast radius: misuse yields only information disclosure, not financial or operational harm.
