Confusion on Directory rules

[unional]

Under https://github.com/vercel-labs/open-plugin-spec#43-directory-rules:

3. Component directories such as skills/, when present, MUST exist at the plugin root, not inside the metadata directory.

This wording is a bit confusing. Because apparently it can be under a sub-folder ./custom/skills if the example in https://github.com/vercel-labs/open-plugin-spec#61-manifest-object is valid.

May be rewording it to something like:

3. Component directories such as skills/, when present, MUST not be placed inside the .plugin metadata directory.

Is that correct?
