How to install the prompt-rail mod to show your Claude Code prompts as a rail and click back to them

prompt-rail is a mod that lines up the prompts you've sent in a session as bars above the prompt input. Hover a bar to see that prompt and a summary of its turn; click it to jump to that spot in the transcript. It's handy for finding an earlier instruction in a long session. It's a community mod by Oikon and runs on Claude Code 2.1.287 or later, where mods are on by default.

1. Add the marketplace and install from your shell. Inside a session, /plugin marketplace add and /plugin install do the same.

claude plugin marketplace add oikon48/prompt-rail
claude plugin install prompt-rail@oikon48

1. Start a new session and the rail opens on its own.
2. Change where it sits with a command. You can also pick it from Rail mode in /config, and the choice is kept across sessions.

/prompt-rail horizontal   # above the prompt (default)
/prompt-rail vertical     # pane beside the transcript
/prompt-rail below        # under the hint line below the prompt
/prompt-rail off          # hide

/prompt-rail 12 jumps to prompt #12, and /prompt-rail find <words> jumps to the newest prompt containing those words. The README says mouse works best with "tui": "fullscreen" in your settings.
