dsh-tuanjie-plugin

DeepSeek Harness plugin that drives the Tuanjie (团结引擎) editor — connect to a running editor's Codely bridge, build and modify scenes and GameObjects, edit component properties, run editor commands, and execute C# inside the editor process.

Docs: README.zh.md (中文文档)

Install

dsh plugin add github:ThePuristImpurity/dsh-tuanjie-plugin

Or search for tuanjie in the DeepSeek Harness plugin marketplace.

Requirements

The Tuanjie editor must already be running with the target project loaded, and that project must ship the Codely bridge (cn.tuanjie.codely.bridge, bundled with Tuanjie by default). This plugin cannot launch the editor for you.

Tools

Tool	Purpose
tuanjie_status	List connectable editor instances (port, project root, state)
tuanjie_list_commands	List every command the editor exposes, with supported actions
tuanjie_command	Run a named command, e.g. manage_gameobject + ["create", "--name", "Player"]
tuanjie_eval	Execute C# inside the editor process with full UnityEngine / UnityEditor access
tuanjie_cli	Run the underlying bridge subcommands (status / editors / command / shell)

Reliability (0.1.1)

The 0.1.0 line had one nasty failure mode: a wrong argument type was silently dropped by the bridge while it still answered success: true. 0.1.1 normalizes and validates arguments in the CLI adapter, so these either work or fail loudly:

Invocation	0.1.0	0.1.1
--position "1,2,3"	silently dropped, nothing moves	coerced to an array, actually applies
--componentsToAdd BoxCollider	silently dropped, Transform only	wrapped into an array
--propertyValue "1,2,3"	zeroes out the vector	coerced to an array, no longer zeroed
--types warning	ignored, returns every type	returns warnings only
--name=X (equals form)	stored as a key literally named name=X	equivalent to the space form
delete --name X	Target GameObject ('') not found	rejected, tells you to use --target
--output out.png	silently ignored	rejected, points at --path / --filename
misspelled flag (e.g. --filterTypo)	silently ignored	rejected with a spelling suggestion
apply_text_edits without line/column	inserts at the top of the file, still reports success	rejected before sending
--imports System.Text	overrides the default namespaces, CS0103	merged into the defaults
modify --componentName X --propertyName Y --propertyValue Z	reports success, field keeps its old value	rejected, points at set_component_property / --componentProperties
modify --componentProperties '{"Typo":{…}}'	One or more component property operations failed, no hint which	names the missing component and lists the ones the object really has
modify --componentProperties '{"m_LocalPosition.x":5}'	success: true, nothing written	rejected, tells you to nest it under a component
apply_text_edits --edits '[]'	bridge answers No edits provided.	rejected before sending

An unknown argument is now caught before the request is sent, and the error lists every parameter that tool accepts. If the bridge answers with No modifications applied, 0 targets found, or not found using method, the envelope is downgraded to a failure.

Even so, verify writes with tuanjie_eval — the plugin cannot change the bridge's own behaviour.

tuanjie_eval accepts quotes and backslashes as written (no escaping needed), and Debug.Log output comes back in data.logs.

Known limitations

• The bridge cannot launch the editor; it only attaches to a running instance.
• capture_game_view is disabled by the bridge. Use manage_gameview, or record_game_view on exec_runtime_script (requires ffmpeg).
• Screenshots land where --path + --filename say (relative paths resolve against the project root); read the real path from data.path. --path may name the file directly when it ends in .png (--path screenshots/Foo.png): the value is split into directory + file name, while an extension-less --path still means a directory that the bridge names itself. Captures always write PNG — the bridge appends .png to --filename whatever it is given — so other image extensions (.jpg, .gif, …) are rejected with an error instead of silently turning into a directory.
• Keyboard and mouse-move input via manage_input needs the Input System package (com.unity.inputsystem). Clicking uGUI elements does not — it goes through the EventSystem.
• tuanjie_cli is not the Unity Hub CLI: projects create, templates list, open, pipeline install, test, build, logs are all unsupported.
