Problem

When running quarto use template organization/template, extensions included in the template fail to copy. An empty _extensions folder is created instead.

Solution

Pass extDir instead of stagedDir to copyExtensions() on line 160 in src/command/use/commands/template.ts.

Changes

• Fixed argument passed to copyExtensions() call in useTemplate() function

Testing

The fix ensures that:

• Extensions found during initial staging are also found during the copy phase
• Template extensions are properly installed along with template files
• No empty _extensions folders are created
