Error Message

Impact: Silent data loss — the user believes an image/file was shared; the model can't see it and responds as if nothing was attached. No error is surfaced on the remote client. An attachment sent from a remote-control client (browser/mobile) should reach the model in that same message, exactly as it does from the host device — full parity regardless of origin device. If it genuinely can't be delivered, the client should show an error at send time, not a successful "sent."

What's Wrong?

Remote-control sessions (browser/mobile) silently drop attachments — shown as sent, never reach the model

Environment: Claude Code session hosted in VS Code; continued via Remote Control from a separate browser / mobile-app device. Windows host.

Repro:

  1. Start a session on the host device (VS Code extension).
  2. Continue/drive that session from a remote device (browser or mobile app) via remote control.
  3. From the remote device, attach an image/file to a message and send.

Actual behavior: the remote client shows the attachment as successfully attached/submitted, but the model receives the text with no attachment. Attachments sent from the original host device arrive normally.

Impact: Silent data loss — the user believes an image/file was shared; the model can't see it and responds as if nothing was attached. No error is surfaced on the remote client.

What Should Happen?

Expected: An attachment sent from a remote-control client (browser/mobile) should reach the model in that same message, exactly as it does from the host device — full parity regardless of origin device. If it genuinely can't be delivered, the client should show an error at send time, not a successful "sent."
