AI agents call check_my_turn to retrieve information from Gomoku without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads the current turn state of a Gomoku game. It performs no side effects, creates no data, executes no code, deletes nothing, and moves no money. It is a simple status check, making it a Read category tool with low severity.
