What
Skill-name validation gained a rule blocking (, ), , and C0/C1 control characters, so those names now fail up front rather than producing a name that cannot match a directory.
Details
Sits on top of the existing unpaired-surrogate, whitespace and wildcard rules.
The error explains that skill names must match the skill's directory name.
Applies to everyone on this build.
Evidence
parentheses, commas, and control characters are not allowed in skill names
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
