prompt-rail

A rail of your prompts for Claude Code. Hover to read one, click to jump back to it.

prompt-rail demo: hovering the rail previews a prompt and its turn, clicking jumps the transcript to it

Quick start

  1. Turn on function hooks (early access, Claude Code 2.1.280+) in ~/.claude/settings.json:

    { "env": { "CLAUDE_CODE_ENABLE_FUNCTION_HOOKS": "1" } }

  2. Install, from your shell or inside a session:

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

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

  3. Start a new session. The rail opens on its own.

Mouse works best with "tui": "fullscreen".

Two layouts

Horizontal, above the prompt (default)

The horizontal rail: a text line with the hovered prompt and its turn summary over a row of bars

Vertical, beside the transcript

The vertical rail: one row per prompt in a pane beside the transcript, the prompt being read marked with a thick tick

Commands

Command
/prompt-rail horizontalBars above the prompt input
/prompt-rail verticalA pane beside the transcript
/prompt-rail offHide the rail
/prompt-rail nextJump to the next prompt
/prompt-rail prevJump to the previous prompt
/prompt-railReopen the rail in the current layout

The layout is also the "Rail mode" row in /config, and it is kept across sessions.

Tick legend

TickMeaning
━ ┃The prompt you are reading
─ │Any other prompt
┄ ┆A prompt Claude Code refused to scroll to; next and prev skip it

How it works

From the transcript file to the rail 
flowchart LR
  T[transcript .jsonl] -->|every prompt on the live branch| R[rail]
  S[rows on screen] -->|topmost row's prompt| R
  R -->|click, next/prev| J[scroll that prompt's row into view]

The rail lists the prompts of the live branch, so prompts abandoned with /rewind drop out, and prompts from before a resume are listed too. The prompt you are reading owns the topmost row on screen. The transcript is read again only when its size or time changed.

Limitations

Known limits
  • Function hooks are early access, and their API may change between Claude Code releases.
  • The hover card with the turn summary is part of the horizontal rail; the terminal alone draws it.
  • The Claude desktop app shows no rail. Checked with its bundled Claude Code 2.1.280, the engine reports the pane as placed, but the app never asks the plugin to draw it.
  • The dock width is shared by all plugin panes; drag its edge to narrow it, down to 24 columns.
  • A /compact command's own row cannot be jumped to; its tick turns dotted after the first try.
  • Near the end of the transcript, next cannot scroll further.

Development

claude --plugin-dir plugins/prompt-rail        # load this checkout; saving reloads it
claude plugin validate plugins/prompt-rail
claude plugin test plugins/prompt-rail

Run /plugin-types .claude/types in a session here for type declarations. Bump the version in plugins/prompt-rail/.claude-plugin/plugin.json with each release, since installed copies update only when it changes.
