What's Wrong?

When connected to a local Claude Code Remote Control session from the Claude Android app, typing @ in the message box does not show any file autocomplete suggestions. Typing additional letters after @ (to filter by filename) also produces no suggestions list

What Should Happen?

According to the official documentation (https://code.claude.com/docs/en/remote-control), Remote Control connects "the Claude app for iOS and Android" to a local session, and explicitly states: "typing @ autocompletes file paths from your local project." This should work identically on Android, the same as it does on desktop/terminal

Error Messages/Logs

No error message. The autocomplete dropdown simply never appears, no console errors visible

Steps to Reproduce

• On desktop (Windows), run claude remote-control inside a project directory
• Scan the QR code / connect from the Claude Android app
• In the Android app's message input, type @
• Type additional letters to filter (e.g. @rea)
• Observe: no file suggestion list appears at any point

Expected: a dropdown list of matching files/folders from the local project, as happens when typing @ directly in the terminal
