ot_new_game · Ttt MCP: Risk & Policy

WHAT IT DOES

What ot_new_game does on Ttt

AI agents invoke ot_new_game to trigger actions in Ttt. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ot_new_game needs a policy

This tool executes game initialization logic with side effects (creates game state, sets up board, triggers game flow). While not destructive or financial, it actively runs operations whose effects depend on game parameters. The vague description ('Provide the human player' appears truncated) and naming pattern suggest active execution rather than simple reads or writes.

From the tool's definition Tool name 'ot_new_game' and description 'Begin the journey to the Well at Eldenmoor' indicate this initializes a game state and triggers external game logic.
