Installation

Requires OpenCode V2. This plugin works in the terminal interface only.

opencode plugin add opencode-sidebar-prompt

No cloning or build step is needed. Open a session in a terminal wide enough to show the sidebar.

Usage

• The sidebar shows the latest submitted prompt for the current session, including queued prompts marked Queued. Unsent drafts are not shown.
• Click Open full prompt, run /lastprompt, or select Show full last prompt from Ctrl+P to read the complete text. The command also works with the sidebar hidden.
• Scroll with the mouse, arrow keys, or PgUp/PgDown. Press Esc to close.
• Attachment-only prompts are marked as such; file and image contents are not displayed.

The plugin adds to the existing sidebar and does not require opencode-sidebar-tokens.

Options

To change the preview length, edit the plugin's existing entry in ~/.config/opencode/cli.json (or $XDG_CONFIG_HOME/opencode/cli.json), not opencode.json. Keep your other plugins and settings.

{
  "$schema": "https://opencode.ai/v2/cli.json",
  "plugins": [
    {
      "package": "opencode-sidebar-prompt",
      "options": {
        "previewLength": 180
      }
    }
  ]
}

previewLength limits the preview to 40–600 characters, including the ellipsis. The default is 180.

No keyboard shortcut is assigned by default. To add one, include this in cli.json:

{
  "keybinds": {
    "sidebar.prompt.open": "ctrl+alt+shift+l"
  }
}

Configuration changes apply automatically; use /reload if needed.

Privacy and troubleshooting

The plugin does not store additional copies of prompts, collect telemetry, or contact external services. Prompts are visible in the sidebar, so take care when sharing your screen.

If loading fails, click Click to reload in the sidebar or run /lastprompt again.

Update or remove

opencode plugin update opencode-sidebar-prompt

If you installed a pinned version, use the same name@version reference to remove it. Pinned versions are not updated automatically.
