Install

At the prompt of a Claude Code session in a terminal:

/plugin install paste-preview --marketplace alan890104/claude-code-paste-preview

Answer `y` to add the marketplace, then pick a scope (user scope loads it in every session). It runs at once, with no restart.

A [Claude Code](https://claude.com/claude-code) mod for the images you paste. In the terminal a pasted image is just `[Image #1]`, and three pastes later you can't tell which is which. With this mod:

You see what you pasted. Every [Image #N] in the prompt box shows as a thumbnail above the prompt, and sent prompts show theirs in the transcript, each labelled Image #N.
You can mark it up before sending. An editor opens the moment you paste: pen, ellipse, box, arrow, text, crop, rotate, seven colours, undo. Press Enter when done, or Esc to keep the picture as pasted.
Claude gets the marked-up version. At Enter the original paste is left out of the message and Claude is pointed at the edited picture.
Full screen works on macOS. There the editor is a native floating panel that sits over a full-screen terminal the way Spotlight does: no Space switch, and the keys return to the prompt when it closes. It waits ready in the background, so it appears the instant you paste (about 100 MB while it waits; after 20 minutes unused it quits, and comes back as you type). On Linux and Windows it opens as a browser app window.
