dsh-rightbar-quicknav

Right-sidebar quick navigation for DeepSeek Harness (DSH) — a vertical icon rail that jumps straight to any right-sidebar tab.

What it does

DSH puts every right-sidebar feature (Files, Git, Tasks, Terminal, Browser, Image Studio, Memory…) behind a tab strip you have to open first. This plugin adds a standing icon rail directly under the open right sidebar button:

• Collapsed, it shows only 3 icons — almost invisible until you need it.
• Hover it and it expands downward to reveal every available tab.
• Hover an icon and its title appears in a compact bubble.
• Click an icon and the right sidebar opens straight on that tab — one click instead of three.

The list is not hard-coded: it is read from the host's own tab registry (sidebarRightTabs.guide()), so any plugin that registers a tab appears in the rail automatically.

Install

Through the plugin manager (recommended)

Plugins → Add and point it at this package (npm tarball or a local directory). The bundle patch wires the client half into the Web/Desktop profile.

Manual

cd ~/.dsh/profiles/<your-profile>
pnpm add dsh-rightbar-quicknav

Then restart DSH completely — client modules are composed at boot, a page refresh is not enough.

Requirements

• DSH >= 0.2.1-rc.1 (needs the sidebarRightTabs / sidebarRight client services)
• React provided by the host — this plugin has no runtime dependencies and no build step

Behaviour details

Position	right edge of the viewport, 10px gap; 50px below the host's open right sidebar button
Collapsed	3 icons
Expand	hover (200 ms collapse delay when the pointer leaves)
Tooltip	single line, auto-width, flips to the other side when there is no room
Jump	sidebarRight.openTab(kind)
Hidden when	the right sidebar is already open, or no session is on screen

Design boundaries

• Mounts only into the additive shell.overlay slot — never covers or replaces shipped UI.
• All visuals are inline React styles: the host exposes no styles service, so class-based CSS would silently do nothing.
• Geometry is event-driven (MutationObserver + ResizeObserver), with zero polling and zero forced layout in steady state.
• The anchor is the host's own button, located by the stable attribute data-sidebar-right-expand, with an aria-label fallback; if neither matches, the rail falls back to a default position and logs one warning instead of disappearing or mis-anchoring.
• Keyboard accessible: the rail is a toolbar with roving tabindex and arrow keys, Esc closes the tooltip, focus outline is keyboard-only.
• Respects prefers-reduced-motion; a render-time exception is caught by an ErrorBoundary instead of blanking the slot.
• UI strings are bilingual (zh / en) and registered under the rightbarQuicknav locale namespace when the host provides one.

Audit

This plugin has been through a full audit and a follow-up remediation round; both are in the repository:

• AUDIT-2026-11-06.md — full audit: scoring, findings, roadmap
• AUDIT-a11y.md — interaction & accessibility review
• AUDIT-perf.md — performance & resource review
• AUDIT-2026-11-06-REMEDIATION.md — per-item verification and remediation ledger

Development

node --check client.js     # syntax
node --test tests/         # render smoke tests (zero dependencies)

The render smoke test loads the real client.js, drives the plugin's own apply() → slots.inject → slots.register path with a minimal React stub, and asserts that rendering and effects do not throw. It exists because a single undefined identifier in an effect once made the whole rail silently disappear.
