Why razz_join_room is rated Medium
Joining a room is a reversible state-change (Write) — it modifies the user's membership/presence in the room. While the server context involves SOL wagering, joining a chat room itself does not directly move funds or execute code. However, it is a prerequisite for further actions (sending messages, reading history), and in a gambling context could facilitate financial exposure indirectly.
From the tool's definition Join a chat room. You must join before sending messages or reading history.
