Unclear It is not clear which setting accepts the leading-minus exclusion, so readers cannot yet rely on it.
What
Claude Code checks some lists by looking for a value in them. That check now ignores upper and lower case and extra spaces. A match still counts as allowed. An entry written with a leading minus, such as -value, now means that value is explicitly left out. Before, a list could only include values, not exclude them.
Why
This gives some allow lists a way to say "everything this covers except this one".
