What's Wrong?

First off, PLEASE DON'T JUST CLOSE THIS, ie.
<img width="1800" height="1350" alt="Image" src="https://github.com/user-attachments/assets/453c2e59-73bc-464b-9e9c-afee5224e394" />

There are (at least) three other duplicates where you did exactly that, but closing our tickets won't actually make the problem go away ☹️

In the Claude Code terminal TUI (mouse-capture / fullscreen rendering), right-click is hard-bound to "paste clipboard into the prompt," with no opt-out short of disabling mouse capture entirely. If the clipboard holds an image (e.g. a screenshot), a plain right-click dumps the raw image data straight into the input.

It also kills normal terminal right-click inside Claude Code: you can't right-click a URL that Claude printed to open or copy it — right-click only ever pastes. Right-click behaves normally in every other app (Chrome, etc.); only Claude Code captures it.

What Should Happen?

Right-click in the TUI shouldn't be globally hijacked as "paste." Either leave right-click to the terminal's native behavior, or add a setting that keeps mouse capture (link-click, scroll, click-to-expand) while NOT binding right-click to paste. At minimum, a plain right-click should never silently paste a clipboard image into the prompt.

Error Messages/Logs

Steps to Reproduce

1. Run Claude Code in a terminal with mouse capture active (default fullscreen rendering).
2. Copy an image to the clipboard (e.g. take a screenshot).
3. Right-click anywhere in the prompt input.
4. Instead of a context menu or any native action, the clipboard image is pasted into the input as raw image data.

Also: right-click a URL that Claude printed in its output — instead of open/copy-link, it just pastes the clipboard.
