What

Claude Code can read credentials (login details) from a file on the host machine. When that source is not a regular file, for example a pipe that passes data from one program to another, Claude Code now flags the credentials as read-once.

Why

This changes how passed-along credentials are cached, since a pipe cannot be read a second time the way a file can.
