Unclear Which feature reads files through this helper is not identified.

What

A helper Claude Code uses to read files as text now refuses a file that contains a NUL byte, a zero character that normally shows up in binary files such as images or programs. Before, it refused only things that were not files and files that were too large.

Why

Binary files are now turned away instead of being loaded as garbled text.
