What's Wrong?

GitHub integration in Claude.ai (web interface) is showing 0% capacity for ALL files and folders when trying to add content from a connected repository.

The file/folder structure loads correctly (can see folder names like src/, deploy/, scripts/, etc.), but:

• All folders show "0%" capacity
• All files show "<1%" capacity
• Total capacity shows "0% da capacidade utilizada" (0% capacity used)
• Previously this was working and showing correct percentages (e.g., 27%)

This happens despite:

• GitHub App having correct permissions (All repositories, Read & Write access)
• Repository being accessible and up-to-date on GitHub
• Connection showing as active

This appears to be the same issue as #10647 but occurring again in January 2026.

What Should Happen?

When adding content from GitHub:

• Files and folders should display their actual capacity percentage
• Content should be accessible and loadable into the chat/project context
• Capacity indicator should reflect the real size of selected content

Error Messages/Logs

No error messages displayed. The UI simply shows 0% for all items without any error indication.

Steps to Reproduce

1. Go to Claude.ai (web interface)
2. Start a new chat or open a Project
3. Click "+" to add content
4. Select "Add content from GitHub"
5. Select a connected repository (e.g., yanzer0/temporal-project)
6. Observe that all folders show "0%" and all files show "<1%"
7. Note that bottom bar shows "0% da capacidade utilizada"
8. This was previously working and showing correct percentages

Similar to issue #10647 - appears to be a recurring platform-wide regression.
