Desktop app (Windows): SendUserFile attachment cards open the file instead of offering a download

Description

When Claude sends files with the SendUserFile tool (display: "attach"), the file cards rendered in the conversation don't offer a download on click — clicking the card just opens/previews the file. There is no apparent way to save the file from the card, which defeats the purpose of an attachment card for deliverables like .xlsx/.pptx.

Environment

• Claude Code desktop app on Windows 11 Enterprise (10.0.22631)
• Local agent-mode session; files sent from a local scratchpad path and from the project directory (a OneDrive-synced path with spaces) — same behavior from both

Steps to reproduce

1. Have Claude produce a binary deliverable (e.g. an .xlsx or .pptx) and send it via SendUserFile with display: "attach".
2. Click the resulting file card in the conversation.

Expected

A save/download action (or at least a "save as" affordance on the card).

Actual

The file opens/previews; no download is offered. Workaround used: Claude copies the file into the project folder so it can be opened from Explorer.
