Type of Behavior Issue

Claude ignored my instructions or configuration

What You Asked Claude to Do

I asked and its also as an memory instruction when i want ui changes to check the whole page identify other parts that working and then apply the fix. I need more than 5 chats with the screenshot while sonet replies that its fixed.
Fails to make simple ui fixes or understand that what i actually told to do and read the whole page is not done.
After 5 or more retries then it will be fixed.
It can create a full api with 15% usage of 5 hours limit and 25% just to fix a button that is not adaptive while there are four buttons bellow that are working fine.

What Claude Actually Did

After 5 or more retries asking for the same thing it finally replied with :
