File references with @ should index into sub-repositories #2121
Description
Describe the feature or problem you'd like to solve
When working in a git-managed folder with multiple sub-repositories, the @ operator should find files in sub-repos as well
Proposed solution
My workflow is to run copilot in a folder with several repositories tracked in GitHub:
project-folder
- subrepo-1
- subrepo-2
- subrepo-3
Until recently, this worked great with the @ operator. I could use @ to add any file from the subrepo-folders or from the main project folder to the context.
What changed is that I recently made the root project-folder a git-enabled repositiory (with a .gitignore file excluding the sub-repo folders). My goal was to keep an upstream backup of skills, copilot-instructions.md, etc. Now, however, the @ operator will only reference files in project-folder, and does not appear to index any of the subrepo folders.
I would like to use the @ operator again to reference all files in the tree, while still keeping my root project files backed up.
