Unclear Whether the remote switch behind this refusal is on by default is not known.
What
Claude Code lets some read-only commands run without asking you. On Windows, these commands no longer get that treatment when an argument tells them to read a list of file paths from another file:
sha256sum, sha1sum, md5sum with --check
wc and du with --files0-from
strings with an @file argument
This refusal sits behind a remote switch. A remote switch is a setting Anthropic can turn on or off from its servers.
One read-only command check is also stricter now about arguments that look like flags or start with +. Matching commands against your permission rules has new logic for comparing the start of a command.
Why
This closes a gap on Windows. A command that looked read-only could have been pointed at a list of other files and read them without asking you.
