DEEPSEEK HARNESS LEARNING CENTER
Understand the system. Shape the interface.
Start with the current Alpha setup and learn Themes, Full Skins, and 100 selected Plugins through real tasks. Every guide includes an example, steps, and a prompt to try.
Orientation
Learn how themes, installation, and rollback work
Choose a numbered item, check its preview and compatible version, then follow the installation steps and keep a way to restore your previous setup.
Choose the right format
Decide between a Theme and a Full Skin before you install.
Check the preview and version
Compare light and dark previews and check the supported Harness version before installing.
Use the documented install workflow
Use the Agent-assisted or manual workflow without skipping checks.
Verify and keep a rollback
Check that the change works and keep the previous package or recovery instructions.
Beginner path

- 01Understand the workbenchLearn how plugins, profiles, workspaces, permissions, sessions, and the Web UI fit together.
- 02Choose what to changeChoose a Theme to change the 13 interface colors, or a Full Skin to add artwork, backgrounds, and visual styling.
- 03Check both modesOpen the Gallery, filter to Themes, and compare the light and dark previews before choosing.
- 04Install by number and keep a backupCopy the numbered installation task for your Agent. Check the supported version, keep a backup, and follow the guide to restore your previous setup if needed.

What is DeepSeek Harness?
A beginner-friendly introduction to the local Agent workbench, what it can do, and the safety choices you still control.
- Official dsh-v0.1.3-alpha.1 README and architecture at source commit d347e703
- Official Web UI guide
- Fixed 0.1.3-alpha.1 source and item-level verification
DeepSeek Harness technical concepts: a quick reference
Look up DeepSeek Harness terms, then use a small CSV exercise to connect models, tools, context, sessions, and file changes.
- DeepSeek Harness alpha.1 architecture and Web UI vocabulary
- DSH Themes publication and appearance vocabulary
- Professional definitions paired with short everyday explanations
What is DSH Themes?
Understand the independent catalog, evidence model, publishing boundary, and local installation workflow around the Harness Web UI.
- Official ThemeRuntime token surface
- Fixed 0.1.3-alpha.1 source and item-level verification
- Theme Manager, Community Skin Installer and Plugin Installer
DeepSeek Harness vs Codex desktop and Claude Code
A plain-language comparison of three Agent workbenches, focused on where they run, how you use them, and which kind of work each one suits.
- Official DeepSeek Harness architecture
- Official Codex desktop app, environment, worktree, and permission documentation
- Official Claude Code overview and permission documentation
DeepSeek Harness quick start
Launch the official Web UI, configure a model, choose a disposable workspace, understand approvals, and run a first task.
- Exact Alpha source-build launch
- Official Web UI guide
- Loopback and workspace safety boundary
Choose a Theme or a Full Skin
Choose a color palette or a complete visual change, compare appearance modes, and install by catalog number.
- Simple Theme V3 boundary
- Full Skin V3 boundary
- Published packages versus submission drafts
Install a Verified Release
Verify compatibility and the complete artifact before changing the DSH web profile.
- Fixed 0.1.3-alpha.1 source and item-level verification
- Whole-artifact SHA-256 verification
- Single direct web-profile theme
Switch and Roll Back Precisely
Change one web-profile theme at a time while preserving an exact, verified return path.
- Single active direct dependency
- Exact rollback artifact record
- CLI and real-runtime postflight checks
DeepSeek Harness vs Pi: fix the same bug in both
Run one reproducible coding task in DSH and Pi with identical inputs, prompts and checks; compare permissions, context, sessions and recovery.
- Pinned DSH Alpha sources and current official Pi CLI/session/extension documentation
- The synthetic order-report fixture, reference repair and scoped file recovery executed locally
- No comparative model benchmark or real provider task result is claimed
DeepSeek Harness best practices: two repairs you can verify
Practice a complete DSH workflow with failing fixtures, precise prompts, focused patches, independent checks, session handoff and file recovery.
- Pinned DSH Alpha sources and primary context-management and evaluation references
- Two synthetic Node fixtures, reference repairs and scoped file recovery executed locally
- No comparative model benchmark or real provider task result is claimed
Evaluate and tune
Compare light and dark previews, adjust colors in Token Lab, and choose plugins that fit your work.
Compare Light and Dark Modes
Evaluate a release as a two-mode system instead of choosing from one attractive frame.
- Verified catalog specimens
- Light and dark token pairs
- System-mode runtime boundary
Create your palette in Token Lab
Choose a base Theme, edit 13 color roles in light and dark, check contrast, and export CSS, JSON, or a Theme creation prompt.
- Complete light and dark editing
- Text contrast checks
- CSS, JSON, and Agent prompt exports
Choose Curated Plugins by Use Case
Choose from 100 Plugins by task, install the Top 10 together, or add individual tools by catalog number.
- 100 selected Plugins and a ten-item starter selection
- Ten use cases and ten editorial recommendations ranked from 1 to 10
- Installation, configuration, source, and license checks
Create and release
Create a Full Skin draft with your artwork, then build and test it before submitting it for publication.
Create a Full Skin Draft
Use the Studio to produce a declarative draft without accepting author-supplied executable code.
- Studio image and token constraints
- Declarative FullSkinManifestV3 inputs
- Simulated-preview boundary
Publish with Verifiable Evidence
Move a declarative submission through provenance, runtime, compatibility, and deterministic-build gates.
- Full Skin publication gate
- Fixed 0.1.3-alpha.1 source and item-level verification
- Artifact and payload digest scopes
Common questions
Before you make a change
Answers about formats, compatibility, evidence, and rollback.
Can this website install a catalog item on my computer?
Copy the installation task from an item or the Top 10 collection and give it to your local Agent. The Agent uses the numbered recipe to install and check the package on your computer. Follow the item’s setup instructions for any account, API key, or local service it needs.
What compatibility baseline do current releases use?
This edition targets DeepSeek Harness 0.1.3-alpha.1 at source commit d347e703908d0406b7a7ef80e3a0e594d86b2215. Build that exact source revision for the Alpha walkthrough. A working Harness installation does not prove that every third-party Plugin or Skin works; follow each item’s current setup and verification results.
Why are source and package evidence separate?
The source commit identifies the code used to build a package. The package digest identifies the file you install. Recording both helps check that the downloaded file matches the reviewed version.
Is a Studio preview proof that a Full Skin works?
A Studio preview helps you design a draft. Before publishing it as an installable Full Skin, build the package and test its appearance, startup, switching, removal, and restoration in the supported Harness version.
Why keep only one @dsh-themes/* package active?
These packages change the same interface colors and styling. The theme manager removes the previous theme before installing the next one and checks the resulting configuration.
