 Do not use git to make changes (commit, push, branch, etc.). Read-only git commands (status, log, diff, etc.) are fine.
 
+## Workflow
+
+- When the user gives a direct command, execute it. But when proposing changes on your own initiative, describe the plan and get approval before editing files.

 ## Coding Conventions
 
 - Do not use static functions in Unreal code. Use class methods or namespace-scoped functions instead.
+- Use `LogLuprexIntegration` for log messages, not `LogTemp`.
 - When writing UFUNCTIONs that take an `AActor*`, `UObject*`, or similar "self" parameter, add `DefaultToSelf` meta to that pin. Most functions should have this on the obvious pin so the user doesn't have to manually wire it in blueprints.
