What's Wrong?

If claude code should proccess screenshots from stored files, for example screens-*.png (defined in prompt) and one of files is corrupted, it ended with error taht could not process image. and all
other prompts fails on same error till /clear command is issued. possible cache poison.

What Should Happen?

after repeating same or modified prompt, there should be new image file reading and processing. or should be there some checksum check if file was changed.
