User Message Jumper

An OpenCode TUI plugin that adds a user-message index to the session sidebar.

The plugin helps you jump back to previous user prompts in the active session. Clicking an item scrolls the native OpenCode transcript to that user message and opens a detail dialog for the turn, including the original user message, command/tool titles observed during the turn, and the final assistant reply text.

Features

• Adds a User Messages section to the OpenCode TUI session sidebar.
• Shows recent user prompts for the active session.
• Click the ▸ / ▾ indicator or the User Messages title to collapse or expand the entire message list in the sidebar.
• Provides an all picker with searchable user-message titles and right-aligned timestamps.
• Scrolls the built-in transcript to the selected user message.
• Adds /user-messages and /umsg command aliases.
• Shows turn details: user message, attachments, command/tool titles, and final reply.

Requirements

• OpenCode >= 1.17.11
• Bun-compatible OpenCode plugin runtime

Install From npm

Use OpenCode's plugin installer with the npm package spec:

opencode plugin -g npm:opencode-user-message-jumper

Restart the OpenCode TUI after installing.

Local Development Install

Clone the repository and install dependencies:

git clone https://github.com/asukaneko/opencode-user-message-jumper.git
cd opencode-user-message-jumper
bun install
bun run build:dist

Then add the local checkout path to ~/.config/opencode/tui.json:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    [
      "/absolute/path/to/opencode-user-message-jumper",
      {
        "limit": 12,
        "openDetailOnSidebarClick": true
      }
    ]
  ]
}

Restart the OpenCode TUI after changing the config. Do not start OpenCode with --pure, because that disables external plugins.

Configuration

limit controls how many recent user messages are shown in the sidebar.

openDetailOnSidebarClick controls whether clicking a user-message item in the sidebar also opens the turn detail dialog. When set to false, sidebar clicks only scroll the native transcript. The all picker still opens the detail dialog when an item is selected.

{
  "limit": 12,
  "openDetailOnSidebarClick": true
}

The searchable all picker still includes the full user-message list for the current session.

Usage

• Open an OpenCode session.
• Use the User Messages sidebar section to select a recent prompt.
• Click the ▸ / ▾ indicator or the User Messages title to collapse or expand the entire message list.
• Click all to search all user prompts in the current session.
• Run /user-messages or /umsg from the command palette to open the picker.
• Move through the picker to preview each prompt's position in the native transcript.

Current Limitation

OpenCode 1.17.11 exposes TUI slots, routes, dialogs, and session message state, but it does not expose a public scrollToMessage(messageID) API for the native transcript.

This plugin uses the same internal idea as OpenCode's built-in /timeline command: it finds the rendered message node in the active session and scrolls the surrounding transcript container to it. This is best-effort behavior and is kept isolated in the implementation, so a future public scroll API can replace it in one place.
