Path pattern uses backslashes instead of forward slashes

Warning

Rule Details ​

Files in .claude/rules/ can include YAML frontmatter with a paths field that specifies glob patterns for when the rule should apply. Glob patterns should always use forward slashes (/) as path separators, even on Windows. Backslashes (\) are treated as escape characters by most glob implementations and will not match paths correctly on macOS or Linux. This rule inspects the paths array in frontmatter and reports any pattern that contains a backslash.

How To Fix ​

Replace all backslashes (\) with forward slashes (/) in the paths array of your rule file frontmatter. Forward slashes work correctly on all operating systems.

Options ​

This rule does not have any configuration options.

When Not To Use It ​

There is no reason to disable this rule. Backslashes in glob patterns are always incorrect.
