Slash Command Interference: Image Upload Fails with Read Tool Error

[BobbyWang0120]

Bug Description When using a custom slash command, I've encountered a consistent issue where Claude Code attempts to use the Read tool on an image pasted via Ctrl+V. This invariably leads to a "file not found" error, even when explicitly instructing Claude Code not to read the file but to directly "see" the image. Consequently, Claude Code fails to recognize any user-uploaded images in this scenario. However, when no slash command is used, Claude Code successfully processes and views the pasted images without issue.

To clarify, are you doing something like /my_custom_slash_command Tell me what's in [Image #1], where the pasted image is part of the slash command argument?

Yes

Passing in pasted images to custom slash commands should be supported as of v1.0.38.
