pengyue-polaron/deepseek-harness-genui
Code-first React and TypeScript task apps rendered inline, in Canvas, full screen, or on localhost, with interaction state available to later agent turns and approval-gated MCP and API access.
Install
via npm
Resolves a published tarball rather than cloning the repository, and installs without any extra setup. Swap `web` for your profile name if you run another one.
via GitHub · npm package
Installing from GitHub runs the project's build script, which pnpm blocks until you allowlist it — run the command once and pnpm prints the exact key to add under `allowBuilds` in ~/.dsh/profiles/web/pnpm-workspace.yaml.
What happened when we ran it
Installed cleanly when we ran it
Every command here is run in a throwaway container against a clean profile, and the result is whatever the harness recorded — not a guess from the source. Last run 15d ago.

For maintainers: the badge serves this listing's latest sandbox verdict, so a re-run updates it on its own — and it links readers to the full result here.
Due diligence
What it is — Agents can build interactive interfaces with React and TypeScript, saving user choices for later agent turns.
Who it is for — When tasks require visualizing complex relationships or making connected choices like calendar planning or photosynthesis exploration using DeepSeek Harness, this plugin offers better interaction than text alone. If your profile is TUI or headless rather than Web, you do not need to install it.
Watch out — Successfully tested in sandbox on a new profile where it was registered to DeepSeek Harness. No obvious issues found.
The verdict — I would install it because saved interaction states let later agents continue tasks without repeating user inputs.
Generated by grok-4.6, and a starting point rather than a verdict. Where it says a plugin installs or does not, that is from a real run in a clean profile — everything else is read off the repository. Trust the source over this.
deepseek-harness-genui is a DeepSeek Harness plugin that lets an agent create task-specific React and TypeScript interfaces instead of expressing every task in prose. The Coding Agent writes ordinary React + TypeScript; the plugin builds and checks the result, then renders the app Inline, in Canvas, full screen, or through a localhost link. The app writes semantic task values such as selections, form answers, drafts, and progress, which later agent turns can read without asking the user to repeat them.
DeepSeek Harness GenUI also provides an approval boundary for connected access. An app declares the Harness, MCP, Skill tools or credential-free public HTTPS routes it needs; DeepSeek Harness presents the complete access list for a task-scoped decision, shows changed capabilities again, and blocks undeclared calls. MCP credentials do not enter generated code. The terminal profile is a terminal surface: it returns localhost app links rather than embedding Canvas, so the agent and user can continue through a CLI-led task.
This suits interactive planning, scientific explanations, code-path exploration, and other work involving connected choices or difficult relationships. It is the wrong choice for plain questions, rewriting, summaries, and simple lists that are clearer in prose. It also requires Node.js ^22.19.0 || >=24, DeepSeek Harness ^0.1.0-rc.6, and Playwright Chromium for the Web profile.
DeepSeek Harness provides the plugin configuration under Settings → Plugins → Plugin configuration. New apps can use automatic design selection, one of the built-in profiles, or an imported custom DESIGN.md. The selected design becomes the default for later apps; existing apps retain their original design. DESIGN.md controls the visual language, not the page structure. The documented built-in profiles are:
editorial-workbench for reading, planning, forms, and content-heavy workledger-grid for comparisons, schedules, evidence, and shortlistsfield-atlas for scientific, causal, and spatial explanationskinetic-signal for changing data, connected tools, and user-triggered actionsDeepSeek Harness starts the Web profile with dsh --profile web. This profile supports Inline, Canvas, fullscreen, and localhost links. The terminal profile uses dsh --profile tui; it returns localhost links and does not embed Canvas. MCP servers must be connected to the same profile. The repository's source-development commands are pnpm run typecheck, pnpm test, and pnpm run package:plugin.
The plugin stores an app's selections and inputs in the current task. Inline, Canvas, fullscreen, and CLI/localhost are surfaces over that same task state, so a later agent turn can read values saved in another surface. Later edits update the same app, while a failed update leaves the current working version in place.
For connected apps, the app declares the Harness/MCP/Skill tools or credential-free public HTTPS routes it needs. DeepSeek Harness shows the complete access list before the task-scoped decision, repeats changed capabilities, and blocks undeclared calls. In Web, access can be reviewed or revoked from the app card.
The plugin requires Node.js ^22.19.0 || >=24 and supports DeepSeek Harness ^0.1.0-rc.6. Generated code runs in a sandbox. Direct API requests are limited to declared, credential-free public HTTPS routes. Temporary links and grants expire after 7 days; saved task state expires 7 days after its last update.
