Type of Behavior Issue

Claude ignored my instructions or configuration

What You Asked Claude to Do

I specifically directed Claude on how to fix an issue in unity.

What Claude Actually Did

Claude proceeded to make some edits enter play mode and then continue editing in play mode when the unity guidance specifically tells him not to do it I have repeatedly told him not to do it and he created a whole memory file specifically to tell himself not to do it but yet repeatedly every time without fail he continues to do so even with specifically engineered prompts that remind him constantly he still does it

Expected Behavior

Claude checks before editing files if the editor is in play mode, or checks the files he's touching aren't actually live environment files

Files Affected

Permission Mode

Accept Edits was ON (auto-accepting changes)

Can You Reproduce This?

Yes, every time with the same prompt

Steps to Reproduce

Ask him to do anything in unity that requires more than 1 second of thought
