dsh-jumpbar
User message jump bar for the DeepSeek Harness (DSH) web GUI.
A minimap-style dash strip floats at the right edge of the conversation
scrollport. Every dash maps to one of your messages (kind user only, not
steering bubbles), positioned by the message's real vertical ratio inside the
transcript. Hover a dash to preview the message content; click to smooth-scroll
the message to the top with a short brand-color highlight.
Install
dsh plugin --profile web add dsh-jumpbar
Restart dsh web, then open any conversation with at least one user message —
the strip appears on the right edge of the chat column.
What you get
- Minimap-style positioning — dash spacing reflects how messages are spread
through the transcript, so you can see at a glance where each user message sits.
- Hover preview — a bubble beside the strip shows the message's text
(action buttons and clock are stripped from a cloned row; the product DOM is
never touched).
- Click to jump — smooth-scrolls the target message to the top (12px gutter)
and flashes a highlight overlay at the settled position.
- Live updates — new messages, loaded history, window/column resizes, and
session switches recompute the strip via MutationObserver + ResizeObserver
with rAF throttling.
- Zero footprint — hidden entirely while no user message exists; floats in
shell.overlay, never squeezing the conversation layout.
How it works
Pure browser-side plugin. It registers one shell.overlay entry and measures
the product's own data attributes ([data-conversation-scroll],
[data-chat-flow-kind="user"], [data-chat-anchor-key]), so it needs no host
logic and changes no product code.
