Dispatch a Claude Prompt Straight from Emacs's Kill Ring

Engineers write prompts as part of the job now, and being able to refer to them in an efficient manner is a valuable improvement to your workflow. Skip pasting file contents into Claude entirely: open find-file (C-x C-f) to surface the path Emacs already knows, select it and cut it into the kill ring (C-a, C-w), cancel out of the prompt without ever loading the file (C-g), then paste the path straight into Claude. Claude reads the file itself — you're handing over a reference, not copying and pasting content.

Bonus: point Claude Code at your live Emacs session directly. In ~/.claude/settings.json:

{
  "env": {
    "EDITOR": "emacsclient -a vi"
  }
}

Any time Claude Code needs to open an editor, it routes through emacsclient — falling back to vi if the Emacs server isn't already running.
