What's Wrong?

Utilizing pluginRoot syntax (as documented per your documentation) results in false flags of invalid plugin's across a marketplace schema.

Verified with claude by loading directly and having access, yet validator pipes out that it is invalid.

What Should Happen?

validation should mark it as correct.
Quite literally following your documentation example.

Error Messages/Logs

invalid plugin on the /plugin validate .

Steps to Reproduce

Follow your own documentation.

I'd laugh if it wasn't so annoying.

You all change documentation so fast, have no version history on documentation being changed, and also have wrong documentation often (rules for instance 2 months back had erroneous glob pattern examples)

Fix the validation bug, start treating documentation on your website as version controlled as well, and allow people to see what was changed, not that hard, and given you all are rolling out so fast, you should provide audit-ability to users.
