A native DeepSeek Harness plugin that turns the Unity Editor into an agent-driven workspace: talk to the Editor, write and attach C# scripts, import your Asset Store library, run tests and builds — all through Unity's official `unity` CLI.

01What can it help you accomplish?
Build a complete Unity game from a natural-language brief inside DeepSeek Harness
A running Unity Editor project — scenes, attached C# scripts, imported assets, tests, and player builds
Game developers and teams using DeepSeek Harness who want an agent to drive the Unity Editor
Edit a live Unity project by talking — add GameObjects, attach components, write gameplay C#
Edited scene graph and attached scripts, with recompile waits handled automatically by the agent
Developers iterating on a live Unity project through conversation instead of manual clicks
Use your owned Unity Asset Store purchases inside the open project
Searched, downloaded, and silently imported `.unitypackage` assets into the running project
Developers who own Asset Store assets and want the agent to import them on Windows or macOS
02How to install into DeepSeek Harness
Prerequisites
- DeepSeek Harness 0.1.2-alpha.5 or newer (older versions are not supported)
- The `unity` command-line tool, installed, signed in, and with an activated license
- Unity 6.0 or newer installed through the Unity Hub (live Editor control requires Unity 6)
- Python 3.9 or newer (only needed for the Asset Store feature)
Installation steps
- 01
$ dsh plugin --profile <name> add @opdsh/unity-plugin
- 02
$ dsh --profile <name>
Verify the integration
- Run `dsh --profile <name> --dump-config` and look for the `# == unity-plugin` section to confirm the plugin loaded
03DSH integration and capability boundaries
Native DSH plugin loaded by the dsh Loader (Node + browser halves); drives the Unity Editor over Unity's official `unity` CLI
Live Editor command (unity_command)
an Editor command name such as create_gameobject, get_scene_hierarchy, or save_scene→the live Editor command result as structured JSON
Every invocation passes `--non-interactive`, so a command that needs interactive input fails loudly instead of hanging the agentRun C# inside the Editor (unity_eval)
a C# snippet→C# executed with full UnityEngine and UnityEditor access inside the running Editor
Executes C# with full UnityEngine/UnityEditor access in the running EditorCLI passthrough (unity_cli)
any `unity` CLI subcommand (projects, open, pipeline install, templates, editors, test, build, auth, license, logs)→raw CLI output for long-running builds and tests
Spawns one CLI process per call; long builds and tests stream raw outputUnity official skills bundled
the bundled Unity-Technologies/skills collection→unity-cli, new-unity-project, build-live-game, UI, package management, physics, optimization, multiplayer skills
Downloads Unity's official skills once per ref into the dsh cache; a failed download falls back to an existing cache
04Who is it for? When not to use it?
Good for
- Game developers and teams using DeepSeek Harness who want an agent to drive the Unity Editor
- Developers iterating on a live Unity project through conversation instead of manual clicks
- Developers who own Asset Store assets and want the agent to import them on Windows or macOS
Not for
- The Asset Store import feature works on Windows and macOS only; Linux is not supported yet.
05Compatibility, maintenance and safety notes
- The Editor command set is discovered at runtime; the plugin does not pin or validate per-command parameter schemas.
- The Asset Store import feature works on Windows and macOS only; Linux is not supported yet.
- `unity_cli` starts one CLI process per call by design; only the four live-Editor tools share the warm session.
- An open Editor holds a Unity license seat until it closes.

06Frequently asked questions
How do I install unity-plugin?
Add it to the DeepSeek Harness profile you use: run `dsh plugin --profile <name> add @opdsh/unity-plugin`, then `dsh --profile <name>`. Confirm the plugin loaded with `dsh --profile <name> --dump-config` and look for the `# == unity-plugin` section.
What can the agent do inside the Unity Editor?
It creates projects and scenes, adds GameObjects and components, writes and attaches C# scripts, runs C# via `unity_eval`, imports owned Asset Store assets, takes screenshots, enters Play mode, runs tests, and kicks off player builds.
Do I need a Unity license?
Yes. The `unity` command-line tool must be installed, signed in, and have an activated license — check with `unity auth status` and `unity license status`. Live Editor control requires Unity 6.0 or newer through the Unity Hub.
Can the agent use my Asset Store purchases?
Yes, on Windows and macOS. The agent signs in with your Unity account, searches your "My Assets" library, downloads the `.unitypackage`, and imports it silently into the open project. Linux is not supported yet.
Which DeepSeek Harness version is required?
DeepSeek Harness 0.1.2-alpha.5 or newer; older versions are not supported. The plugin is loaded by the dsh Loader as a native plugin (Node + browser halves).
