dsh-turnbar

English | 简体中文

A progress bar for your agent conversations.

Long agent sessions are productive — until you need to find that one requirement you mentioned 80 turns ago. Native scrollbars make you guess and re-scroll. dsh-turnbar gives your DeepSeek Harness chat a video-style progress bar: hover to preview any turn, drag to scrub, click to jump, Esc to come back.

Install

Three ways, pick one:

① Plugin market (easiest): open dshmarket inside dsh, search "turnbar", one click.

② Command line: open your macOS Terminal app and paste:

dsh plugin --profile web add dsh-turnbar

This runs in the Terminal app, not in the dsh chat box. If your terminal doesn't know the dsh command (dsh --version says command not found — you never installed dsh globally, e.g. you use a desktop build or let your AI launch it), install it first:

npm install -g @deepseek-ai/dsh

③ Ask your AI: just tell your agent "install dsh-turnbar for me" — it runs the same command on your machine, exactly how you've been installing your other plugins.

Restart dsh afterwards. Zero config; historical sessions are backfilled automatically and the bar always shows the whole conversation.

Features

• 🎚 Full-map progress bar — every turn is a segment; the playhead highlights the segment you're reading. 150+ turns aggregate into ≤40 groups so the bar never becomes a mess.
• 🖼 Hover preview cards — see who said what before you jump: the turn's first lines, tool-call count, file edits, token usage, and steering messages. Terminated empty turns are dimmed and labeled 「该轮已终止，无对话内容」instead of pretending to have content.
• 🔎 In-conversation search — the magnifier button at the bar's right edge or ⌘K opens it. Search everything the agent said or you said, across the whole session (including history beyond what's loaded); results show a count, arrow keys scroll the highlight into view, Enter lands the pick on the bar. Results are also drawn on the bar itself — matching turns glow amber, so a query like "TypeScript" shows you at a glance where in the conversation it lives (v0.3).
• ⛽ Context fuel gauge — hover any turn to see the context window occupancy at that moment ("上下文 62% · 余 38k"), with color escalation at 80%/95%. When the latest turn passes those thresholds, the bar's tail edge glows amber, then red — you notice the tank is nearly empty without even hovering (v0.3).
• 📑 Chapter ticks — /goal rounds are marked as thin ticks on the bar, so a long session gets visible "milestones" without any manual bookkeeping (v0.3).
• 🧭 Trajectory view jump — ⌘/Alt + click a segment opens the official Trajectory view and scrolls to that turn's row, centered and highlighted. Falls back to a normal in-chat jump when trajectory is unavailable (v0.3).
• ⤴ Click / drag to jump — click a segment to land in ≤300 ms; press and drag to scrub through turns like a video timeline. Jumps across unloaded history page it in automatically.
• ⌨️ ⌘↑ / ⌘↓ — hop one turn at a time from where you're reading; empty turns are skipped automatically.
• ↩ Esc to return — after any jump, Esc (or the toast) takes you back to exactly where you were.
• 🧩 Graceful degradation — if your dsh version changes APIs, dsh-turnbar hides itself instead of breaking your session.

Why yet another navigation plugin?

The turn-navigation space filled up fast: dsh has shipped a native turn rail since 0.1.2, and a couple of dozen community plugins now hang previews, search and bookmarks off it. Almost all of them are rails, drawers, or dot chains — a list of messages you click through. dsh-turnbar is the only one shaped like a video player: the whole session is a single always-visible full-width bar, sitting beside the native rail rather than replacing it.

Hover previews and click-to-jump are table stakes by now, so this table only carries what actually separates the closest few — including the rows where they are ahead of us:

	dsh-turnbar	native rail	dsh-milestone	dsh-message-rail	dsh-jumpbar	dsh-codex-timeline	dsh-navbar
Form	full-width bar (bottom dock)	built-in vertical rail	dot timeline (right)	left rail (Codex-style)	right-edge minimap strip	enhances the native rail	right-edge dot chain
Whole session in one view	✅ one bar	❌	⚠️ dots + separate full list	⚠️ full index, pages in on click	⚠️ minimap of messages	❌	❌
Drag scrub	✅ drag across the bar	❌	⚠️ wheel-scroll on dots	❌	✅ drag on the strip	❌	❌
Hover card: tools / files / context	✅	❌ turn number only	❌ time, duration, TTFT, tokens	❌ text + time	❌ text	❌ content, time, tokens	❌
Context fuel gauge (% of window, 80/95% warnings)	✅	❌	❌	❌	❌	❌	❌
Chapter ticks (/goal milestones)	✅	❌	❌	❌	❌	❌	❌
Search hits drawn on the map	✅ amber segments, map kept	❌	⚠️ filters the dots	❌	❌	⚠️ result list	❌
Cross-session search / bookmarks	❌	❌	✅ both	❌	❌	⚠️ bookmarks	❌
Esc returns you to where you were	✅	❌	❌ clears the search instead	❌	❌	❌	❌
Upgrade safety	✅ official slot, both persistence generations	— it is dsh	✅	✅	✅	❌ pinned to 0.1.2-alpha.3	✅

Being straight about it: cross-session search and #msg= deep-link bookmarks are dsh-milestone's, and we don't have them yet; trajectory-view jump is shared with dsh-chat-outline. Still only here: the full-width map itself, the context fuel gauge, /goal chapter ticks, and Esc-return. All of these plugins are MIT and genuinely useful — dsh-turnbar just goes further on the feel: it's a video player, not a list. See also Companions below.

Companions

• dsh-rewind — roll the conversation back to an earlier turn (jump over, then rewind).
• dsh-turn-fold — collapse tool-call storms; its per-turn stats pair well with our preview cards.

Acknowledgements

Built on paths others paved first — with gratitude:

• @vlln's dsh-navbar — the hover-preview / click-to-jump DOM patterns and the wheel+scrollTop jump recipe;
• @YesSanSan's dsh-conversation-outline — the host↔client same-origin JSON bridge pattern and its invaluable PLUGIN_DEV_NOTES.md;
• the DeepSeek Harness team — official slots, session event streams, and persistence APIs that let this plugin take the paved road end to end, zero patches.

Compatibility

Tested against dsh 0.1.5-rc.1 (web profile, handle-based persistence open/read/close) and 0.1.0-rc.7 (one-step inspect/readRaw persistence). Both persistence generations are auto-detected at runtime, so history backfill works on either. Works with the official web UI's conversation.composer.dock slot; no patches, no UI hacks — which is the point: upgrading dsh does not require uninstalling dsh-turnbar first. Plugins that hook in deeper pay for it: dsh-codex-timeline now enhances the built-in rail and supports exactly one dsh build (0.1.2-alpha.3), so its README carries a version matrix and a per-version install. Different trade-off, stated plainly.

Coexists with other plugins that share the same composer.dock slot — dsh-web-ui-all and its included dsh-live-stats / dsh-aionui-panel. A built-in co-existence CSS layer (v0.2.2+) forces the dock into a wrapping row so the TurnBar always owns its own full-width line while the official StatsLine sits beside any third-party entries, so the bar is never squeezed sideways. Single-turn sessions now show a one-segment progress bar too (only brand-new 0-turn sessions stay hidden).

dsh version	status
0.1.5+ (web, handle-based persistence)	✅ full features
0.1.0-rc.5 – 0.1.1-rc.x (web, inspect/readRaw)	✅ full features (legacy chain)
older / non-web profiles	plugin stays inert; nothing breaks

Roadmap

• Next: task-boundary chapters (beyond /goal), bookmarks, trajectory ↔ chat round-trip polish.

Development

pnpm install
pnpm test        # vitest (fold logic, card model, host-half degradation)
pnpm build       # tsdown: lib/index.mjs (node half) + lib/client.js (web half)

Architecture: a dual-half plugin — the node half folds the session/event firehose into per-turn records (persisted sidecar), serves them over /plugins/dsh-turnbar/state; the web half renders the bar into the official composer dock slot. All dsh API contact is confined to src/platform/dsh/.
