What's Wrong?

When starting a new Claude Code session on mobile (iOS), the folder picker shown at the bottom of the screen allows navigation into subdirectories of a GitHub repository, but does not allow selecting the repository root folder itself.

The root folder item is either not tappable or does not trigger selection — only subdirectories can be chosen as the working directory. This forces users to start sessions from a subdirectory rather than the project root.

What Should Happen?

The repository root folder should be selectable in the folder picker, just like any subdirectory. Clicking the root item (or a dedicated "Select this folder" button at the root level) should set it as the working directory for the session.

Error Messages/Logs

No error message shown. The root folder simply cannot be selected — clicking it navigates into it without confirming the selection.

Steps to Reproduce

1. Open Claude for Mac
2. Start a new Claude Code session
3. Choose a GitHub repository
4. A folder picker appears at the bottom of the screen showing the repository contents
5. Attempt to select the repository root folder (top-level directory)
6. Result: the root folder cannot be selected — only subdirectories are selectable

Additional Information

Bug occurs in the Claude for Mac desktop app GUI — not in the CLI.

When the folder picker is shown at session start (bottom sheet after choosing a GitHub repository), only subdirectories are selectable. The root of the repository has no way to be confirmed as the working directory.

Workaround: select any subdirectory to start the session, then use /add-dir to access the root.

Environment: MacBook Pro 16" 2023, Apple M2 Max, 32 GB RAM, macOS Tahoe 26.3
App: Claude for Mac 1.1.4498 (24f768)
