01What can it help you accomplish?
Generate interactive visualizations — simulators, charts, comparison panels, UI mockups — directly inside DSH conversations
Interactive HTML cards rendered inline in the Web UI conversation flow, with streaming preview, component float-in animations and theme following (DSH dark/light theme and whale-blue palette)
DSH Web UI users who want model answers as interactive cards instead of plain text
Replay past sessions with their visualizations intact
Cards restored from persisted tool results on session replay, without depending on the original fragment files still existing
Users who revisit or share long-running DSH sessions
02How to install into DeepSeek Harness
Prerequisites
- DeepSeek Harness (dsh) with the `web` profile
Installation steps
- 01
Run `dsh plugin --profile web add github:Nagi-ovo/dsh-visualize`
$ dsh plugin --profile web add github:Nagi-ovo/dsh-visualize
- 02
If dsh web is already running, restart it and refresh the page
- 03
Alternative (source modification): clone the repo and run `dsh plugin --profile web add .` inside it — build artifacts are already committed, no extra build step needed
$ dsh plugin --profile web add .
- 04
Users of the community plugin-registry can also install from Settings → Plugins
Verify the integration
- Run `dsh --profile web --dump-config` and confirm the plugin appears in the final configuration
03DSH integration and capability boundaries
DSH web profile plugin installed via `dsh plugin --profile web add github:Nagi-ovo/dsh-visualize`; the model calls the `visualize` tool to render interactive HTML cards inline in the conversation
In-conversation generative UI
natural-language request, e.g. "做一个能调参数的排序算法可视化"→an interactive card in the conversation: simulator, chart, comparison panel or UI mockup; `mode: "wide"` for side-by-side content
the model writes an HTML fragment file and invokes the `visualize(path, title?, mode?)` toolSandboxed rendering with CSP
model-generated HTML fragment→card runs in a sandboxed iframe with an opaque origin; CSP blocks network requests, nested pages and form submission, only static resources from a fixed CDN are allowed
static resources are loaded from a fixed CDNFragment size guard
HTML fragment submitted by the model→fragments capped at 1,000,000 bytes by default, adjustable via `maxFragmentBytes`
04Who is it for? When not to use it?
Good for
- DSH Web UI users who want model answers as interactive cards instead of plain text
- Users who revisit or share long-running DSH sessions
Not for
- Interactive cards only render in the DSH Web UI; TUI and headless clients fall back to a plain tool result.
- The repository is very young (created 2026-08-13) and has no tagged release; treat the interface as early-stage.
05Compatibility, maintenance and safety notes
- Interactive cards only render in the DSH Web UI; TUI and headless clients fall back to a plain tool result.
- Buttons inside cards cannot send follow-up messages to the main conversation yet.

06Frequently asked questions
How does dsh-visualize integrate with DeepSeek Harness?
It is a native DSH plugin for the `web` profile: run `dsh plugin --profile web add github:Nagi-ovo/dsh-visualize`, restart dsh web if it is running and refresh the page. It is not an MCP server.
How do I actually generate a visualization?
Just tell the model what you want, e.g. "make a sortable-algorithm visualization with tunable parameters". The model writes an HTML fragment and calls `visualize(path, title?, mode?)` to place it in the conversation; use `mode: "wide"` for side-by-side comparisons.
What are the prerequisites?
DeepSeek Harness (dsh) with the web profile. Users of the community plugin-registry can also install from Settings → Plugins; build artifacts are committed to the repo so no build step is needed.
Are the cards safe to run?
Cards run in sandboxed iframes with opaque origins and cannot touch the host page. CSP blocks network requests, nested pages and form submission, allowing only static resources from a fixed CDN; each fragment defaults to a 1,000,000-byte cap, adjustable via `maxFragmentBytes`.
What are the limitations?
Interactive cards only render in the Web UI — TUI and headless clients show a plain tool result — and buttons inside cards cannot send follow-up messages to the main conversation yet.
