This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

<p align="center">A ChatGPT-style scroll timeline for the chat sidebar: a rail of horizontal bar nodes (one per user message) with magnetic mountain hover, hover preview, and click-to-jump.</p>

<p align="center"> <img src="https://badgen.net/badge/license/MIT/green" alt="license"> </p>

<p align="center"><a href="README.md">English</a> | <a href="README.zh.md">中文</a></p>

An evenly spaced node rail on the right edge of the sidebar (one horizontal bar per user message) — the peak bar follows your reading position, hovering grows a magnetic "mountain" (design ratios 39/30/21/15/9; base and peak widths are adjustable via CSS variables), a hover preview card (6-line clamp), click-to-jump with smooth scrolling and a brand-blue highlight, full history always visible, and auto-hide when there are fewer than 2 user messages. Form factor: an official bundle plugin (dsh.bundle + dshClient channel, browser-only, empty Node half), 0 patches.

> Derived from vlln/dsh-navbar (MIT, spec issue dsh-external/issues#144), with the interaction redesigned: horizontal bar nodes, magnetic mountain hover, sidebar-adjacent positioning, and full history.

Features

FeatureDescription
Scroll timelineVertical node rail on the right edge of the sidebar, one horizontal bar per user message (3px tall, 14px hit area)
Reading positionPeak bar (39px brand blue) follows the current reading position
Magnetic mountainWhile the pointer is over the rail, the nearest node becomes the peak and neighbors extend in progressively decreasing amounts (39/30/21/15/9)
Hover previewHovering a node shows a message preview card (6-line clamp, aligned with the official HoverCard look, opens to the right)
Click to jumpSmooth-scrolls to the message + brand-blue highlight ring
Full historyAlways shows every historical node; long sessions scroll within the container
Auto-hideHidden with fewer than 2 user messages or outside the chat page

Zero data-channel dependencies: driven only by the official anchor attribute (data-time-hover-root, user rows since 0806); no polling, no routes, no tools.

The base and peak widths can be tuned via CSS variables (on the rail container):

[data-dsh-navbar] {
  --dsh-navbar-base-w: 9px;  /* base width */
  --dsh-navbar-peak-w: 39px; /* peak width (hover/active) */
}

Install

Recommended: one-line git install (build artifacts are committed; git sources don't trigger a build):

dsh plugin --profile web add "github:invalidnaaaame/dsh-scroll-timeline#main"

Or from a local directory (with source): git clone, then cd dsh-scroll-timeline && dsh plugin --profile web add ..

After installing, restart web for it to take effect; the Settings → Plugins panel can disable/enable it.

Usage

Works out of the box; no commands, no tools. The timeline appears on the right edge of the sidebar in the chat (Chat) view; hover to preview, click to jump. Animations are disabled under prefers-reduced-motion.

Development

pnpm install
pnpm run build      # tsdown: client bundle (lib/client.js)
  • client: src/client/index.ts (self-rendered DOM + official anchor contract, no React dependency)
  • Node half: src/index.mjs (empty apply; the bundle mount carrier)
