 ### ❌ Don't
 - Send duplicate messages or interaction history
-- Forget to include `version="v2"` parameter
+- Skip identifiers like `user_id` or `run_id` that scope the memory
 - Mix contextual and non-contextual approaches in the same application
 
 ## Troubleshooting
 
 | Issue | Solution |
 |-------|----------|
-| **Context not working** | Ensure you're using `version="v2"` and consistent `user_id` |
+| **Context not working** | Ensure each call uses the same `user_id` / `run_id` combo; version is automatic |
 | **Wrong context retrieved** | Check if you need separate `run_id` values for different interaction topics |
 | **Missing interaction history** | Verify all messages in the interaction thread use the same `user_id` and `run_id` |
 | **Too much irrelevant context** | Use more specific `run_id` values to separate different interaction types |
