## Why razz_get_opponent_history is rated Low

This tool retrieves historical game data about other players. While the broader server involves financial wagering (SOL), this specific tool only queries and returns information—it does not move money, execute game logic, delete data, or trigger external operations.

From the tool's own definition: "Tool description explicitly states it 'Get[s] a player's recent game history' and 'Returns recent results' — purely retrieval operations with 'no side effects' per the Read definition."

## Use case

AI agents call razz_get_opponent_history to retrieve information from Razz Games without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

```json
{
  "version": "1",
