01What can it help you accomplish?
Preview streaming HTML in chat
Self-contained HTML streamed into a sandboxed inline preview
DSH users visualizing charts, diagrams, mockups or interactives
02How to install into DeepSeek Harness
Prerequisites
- Node ^22.19 or >=24; default branch requires DSH 0.1.2-rc.1 or newer.
Installation steps
- 01
Run `dsh plugin --profile web add 'git+https://github.com/abidhmuhsin/dsh-visualizer.git'`; use the desired profile instead of web.
$ dsh plugin --profile web add 'git+https://github.com/abidhmuhsin/dsh-visualizer.git'
- 02
The first attempt is expected to fail: copy its exact commit-specific allowBuilds block into that profile's pnpm-workspace.yaml and rerun the install.
- 03
Boot the profile and ask the model to visualize something.
Verify the integration
- The document should appear inline while the model writes it.
Rollback
- Run `dsh plugin --profile <your-profile> remove dsh-visualizer`.
03DSH integration and capability boundaries
DSH visualizer tool and Web GUI card mounted by one bundle layer
Inline HTML preview
Stream HTML into a sandboxed frame in the DSH conversation.
Download and explicit export
Download a self-contained HTML/SVG file; Export mirrors a settled successful call to disk.
Export writes an artifact file; rendering alone does not.
04Who is it for? When not to use it?
Good for
- DSH users visualizing charts, diagrams, mockups or interactives
Not for
- Older DSH builds need the frozen pre-harness-0.1.2-alpha3-compat branch; new features only reach the default branch.
- Default share links expire after a harness restart; sharing is unavailable without a web server or live sessions store.
05Compatibility, maintenance and safety notes
- Older DSH builds need the frozen pre-harness-0.1.2-alpha3-compat branch; new features only reach the default branch.
- Default share links expire after a harness restart; sharing is unavailable without a web server or live sessions store.

06Frequently asked questions
What does it add to DSH?
A visualizer tool and a Web GUI card for streaming HTML previews.
Why does my first DSH install fail?
pnpm blocks prepare until the exact commit-specific allowBuilds hint is added to the profile workspace file.
Does a DSH preview write files automatically?
No. Disk mirroring begins when you explicitly export a settled successful call.
