What's Wrong?

When using the Claude VS Code extension, files that start with a bracket ([) such as dynamic route files in frameworks like Nuxt (e.g. [id].vue) do not appear in the file search when trying to attach file in the chat.

What Should Happen?

Files that begin with square brackets (e.g. [id].vue, [slug].js) should appear in search results and be attachable like any other file.

Additional Information

These files can still be attached manually if you type their exact relative path (e.g. @pages/[id].vue), but this is so inconvenient.
