Reading the same unchanged image over and over is refused after a limit

The Read tool is how Claude opens files, including images. Claude Code now keeps track of image reads. If Claude reads an image that has not changed past a set limit, the read is refused with "Read of an unchanged image refused past its limit". Reads made from inside other actions only count towards the record. The Read tool also makes one more check on the file path before reading.

The Read tool's own description is unchanged.
