DEEPSEEK HARNESS · START HERE
DeepSeek Harness is a local Agent workbench. It connects a model to tools, a workspace, permissions, and a persistent session, then presents that workflow through profiles such as the Web UI.
In plain language
The model handles reasoning. DeepSeek Harness provides the tools, permissions, session history, and interface.
Cordis composes the models, tools, Agent loop, session log, Web service, and browser UI.
The web and headless profiles assemble different ordered plugin bundles from the same services.
Workspace access follows permission policy, while messages, steps, and tool results become session events.
DeepSeek Harness is in Developer Preview. DSH Themes is an independent community project, not affiliated with or endorsed by DeepSeek AI.

Choose an appearance or a useful tool, copy its numbered task, and let your Agent guide the installation. Review any required accounts or configuration before you begin.
Read the engineering reportThemes adjust colors; Skins change the visual atmosphere; Plugins add tools for your workflow.
Each item shows its compatible Harness version and setup requirements. Your Agent checks these before installing.
Restart Harness when needed and check the result. The installation task keeps instructions to remove the item or restore your previous setup.
Copy the task for the item you want. Your Agent guides you through the steps below.
Submit a declarative Theme, a Full Skin draft, or a visual concept. We review ownership, compatibility, safety, contrast, and real runtime previews before publication.

Creator-supplied declaration and reviewed image references
Ownership, compatibility, safety, contrast, and runtime evidence are reviewed before publication.
Only an approved submission receives publisher-attached package metadata.
The website itself cannot change your local Harness. Copy an item’s #NNNN installation task to your Agent, which checks your setup and the selected package before installing. If the package is not ready for installation, it explains what is missing.
Installing, removing, or switching a DSH Themes package requires a restart in the current Developer Preview. Switching light, dark, or system inside an already installed theme follows the normal Appearance control and does not require another package install.
No. Submissions are declarative. The site generates the adapters and constrained CSS, accepts only reviewed content-addressed images and allowlisted selectors, and rejects dependencies, lifecycle scripts, external URLs, imports, and arbitrary code.
The current compatibility claim stays pinned and is not extended automatically. Each theme must pass the new token catalog and real DSH verification before maintainers publish an updated compatibility record.
A Theme changes the 13 interface color roles. A Skin can also change backgrounds and the visual layout. Open an item to compare its previews, check the supported appearance modes, and see how to install it.
