The extensions I use with DeepSeek Harness.
My extensions, English adaptations, and the packages I keep in my DSH setup.

I use DeepSeek Harness for coding, presentations, research, and longer tasks. This is where I share the extensions I build, the English editions I adapt, and the community packages I use alongside them.
I'm arzvaak. Each entry explains what I use it for and where to get it. Community projects keep their original credits and licenses.
| I want to… | Start with |
|---|---|
| Keep the coordinator available while coding workers run | DSH Conductor — per-task model selection, queued native and official Muse CLI workers, worker controls, and independent review. |
| Create and edit a presentation | Claude Slides — my English edition — a local slide editor with direct editing, comments, and PDF, HTML, or PowerPoint export. |
| Design a website or app screen | Claude Design — my English edition — editable artboards for responsive layouts and interactive prototypes. |
| Build a data-backed dashboard | Claude Dashboard — my English edition — charts, numbers, and tables over data files, with source attribution. |
| Show charts and diagrams in an answer | DSH Visuals — inline charts, Mermaid diagrams, editable previews, and SVG export. |
| Connect BharatCode or another model endpoint | Provider Hub — provider setup and model discovery, with subscription sign-in through the subscriptions plugin. |
| Schedule and track background work | Task Board — Kanban tasks, scheduled runs, and execution history. |
| Understand context usage and costs | Context for context inspection; Cost Meter for usage and cost tracking. |

The four baoyu-design editions share an Artifacts sidebar and local editor/comment workflows. I keep their interfaces, instructions, validator messages, and generated-content defaults in English, including under Chinese browser settings. Download my English packages from the suite’s Releases page; upstream npm downloads do not include these changes. The suite retains upstream authorship and mixed licensing, described in its repository.

| Project | What I use it for |
|---|---|
| Task Orchestrator | Plan-driven delegation, dependency scheduling and review; the upstream foundation for Conductor. |
Choose an extension, then follow its repository's installation instructions. Requirements vary by package and DSH version.
- Source packages: use the repository's documented checkout or GitHub installation path. Build first if that project requires it.
- Package snapshots: download the
.tgzarchive and checksum from that repository's Releases page. These preserve the captured edition; installing the upstream npm package can give you different code or localization. - Subscriptions: install the original npm distribution. Its repository here is an installation reference, not an installable mirror.
Desktop: open Plugins → Add plugin, enter the full path to the downloaded .tgz file, install it, and enable it. My desktop build reserves its profile for the app’s Plugins page.
For a CLI profile such as web:
dsh plugin --profile web add /absolute/path/to/extension.tgzUse your own CLI profile name as appropriate and the CLI belonging to your DSH installation. Follow the extension’s reload/restart instructions, then start a new session to receive newly installed skills.
Source repositories contain development code. Source forks and adapted source retain the upstream project and my changes. Package snapshots preserve a particular installed package, which may include built JavaScript without the full development source. Their DISTRIBUTION.md and INSTALLED-PACKAGE.json describe provenance and captured files.
Each project keeps its own license and attribution. This is an independently maintained collection; inclusion does not imply endorsement by DeepSeek or upstream authors. Compatibility and verification details belong in each extension's README.
I updated the presentation, design, and HarnessMM entries against my desktop profile on 2 November 2026; the rest of the collection was last reconciled on 1 November 2026. The baoyu-design suite replaces PPT Flashmade and Deckforge in my setup. Their repositories remain available as history. Installation state varies by machine.
