 ### Inferring the game
 
-Most players clearly play one game or the other. Look for context clues:
-- OSRS-specific: quest names unique to OSRS
-- RS3-specific: "invention", "archaeology", "divination", "EoC", "revolution"
-- If ambiguous, ask which game they play
+**Always determine the game before running any command.** Use the following rules:
+
+1. **Use stated preference**: If the user has said which game they play earlier in the conversation, use that — no need to ask again.
+2. **Strong context clues**: A few terms are exclusive to one game:
+   - OSRS-only: "leagues", "deadman", quest names unique to OSRS (e.g. "Monkey Madness II")
+   - RS3-only: "invention", "archaeology", "divination", "EoC", "revolution", "legacy mode"
+3. **When in doubt, ask**: If you cannot confidently determine the game from context, **always ask before running any wiki command**. Do not guess. A short question like "Are you playing OSRS or RS3?" takes one message and prevents a useless lookup.
+
+Most content (items, monsters, skills, quests) exists in both games with different stats, locations, and mechanics — so defaulting to one silently is likely wrong.
