Bug Description
I've noticed that Update command failed if try to edit a file from the previous messages in the conversation. The it Read it and The Update command does work. So I'm thinking that maybe claude code should keep track of the file edited throughtout the conversation and which one was already read after editing to prevent the Update - Error editing file issue.
