Paste an image into a remote agent

While attached, copy a screenshot, then press Ctrl+V (Alt+V on Windows). The client uploads the image to the host, into a private folder of the session’s own, and pastes its path. Claude Code, Codex, opencode and the other agents attach an image when you paste its path.

• With no image on the clipboard, Ctrl+V goes to the agent as usual.
• Dropping a file on the terminal window uploads it the same way.
• Uploaded files are private to your user on the host, and deleted after a day.
• The key is a setting: attach.image_paste_key in config.toml.
