Unity MCP skills

Generate a JSON Schema for a C# type name via reflection. Supports primitives, enums, arrays, generic collections, dictionaries, and complex objects. Knobs control inclusion of nested `$defs` and whether type-level / property-level descriptions are emitted.

Provides an initial setup for AI Skills, `unity-mcp-cli` command line tool installation and everything else that is helpful to set up at the start of the project. Essential packages, and basic configurations.

Retrieve Unity Editor logs from the MCP plugin's `LogCollector`, optionally filtered by log type or time window. Useful for debugging and monitoring Editor activity.

Regenerate every `SKILL.md` from the project's currently-registered MCP tools into the configured skills folder (or a project-relative override path). Writes the YAML `description:` from `[AiSkillDescription]` and the body from `[AiSkillBody]`.

Capture a screenshot from the Unity Editor Scene View at the requested size. Renders via the Scene View's active camera onto a temporary `RenderTexture`. Requires an open Scene View.

Clear the MCP log cache (used by 'console-get-logs') and the Unity Editor Console window. Useful for isolating logs to a specific action by clearing the slate first.

Toggle the wrapper's local 'enabled' flag for a named profiler module. Bookkeeping only — Unity's runtime API does not expose direct module control; for real module visibility use the Profiler window.

Create a new skill (MCP tool) for the Unity Editor by writing a C# (.cs) file that Unity compiles into the project. After compilation the new tool becomes callable through MCP. The file must be a partial class decorated with [AiToolType], each tool method must be decorated with [AiTool], the class name should match the file name, all Unity API calls must run via com.IvanMurzak.ReflectorNet.Utils.MainThread.Instance.Run(), and the method should either return a structured data model (for parseable output) or void (for side-effect-only operations). See the body of this skill for a full sample and best-practice notes.

List all shaders available in the project assets and packages, sorted by name. Use this to discover a valid `shaderName` for 'assets-material-create'.

List all Unity-MCP tools registered in the connected Unity Editor instance. Optional regex filter matches against tool name, description, and argument names/descriptions. Use the `includeDescription` / `includeInputs` toggles to control the response size.

List all known profiler module names with their local 'enabled' bookkeeping flag.

Find C# methods across every loaded assembly by name / type / parameters — including private methods. Returns serialized `MethodData` entries usable as schemas for 'reflection-method-call'.

Compiles and executes C# code dynamically using Roslyn. Supports a full-code mode (default) and a body-only mode — see the skill body for the difference and for how to pass Unity object references as parameters.

Open a Unity scene asset in Single or Additive mode. Returns the post-open list of all opened scenes. Use 'assets-find' to locate the scene asset first.

Save a snapshot of profiler-derived stats (status + memory + rendering + script + frame capture) to a JSON file. Built-in Unity APIs only.

Add one or more Components to a GameObject in the opened Prefab or active Scene. Component types are looked up by full name (with namespace) or by class-name fallback. Use 'gameobject-find' to locate the host GameObject and 'gameobject-component-list-all' to discover valid component type names.

Modify a Unity `UnityEngine.Object`'s serializable fields/properties. Three modification surfaces are available (`objectDiff`, `pathPatches`, `jsonPatch`) — see the skill body. Use 'object-get-data' first to inspect the object structure.

Create a Prefab (or Prefab Variant) at a project asset path. Source can be a scene GameObject (`gameObjectRef`) or an existing prefab asset (`sourcePrefabAssetPath`). Creates intermediate folders if missing. Use 'gameobject-find' to locate the source GameObject first.

Get information about the current Selection in the Unity Editor — active object, active transform, selected GameObjects, transforms, instance IDs, and asset GUIDs (each enrichment is opt-in). Pair with 'editor-selection-set' to change the selection.

Lightweight readiness probe. Returns the input `message` echoed back, or `'pong'` when omitted. Useful for CLI health checks and SignalR connectivity smoke tests.

Close the currently opened prefab edit stage. Optionally saves changes back to the prefab asset before closing. Pair with 'assets-prefab-open' to enter the edit mode first.

Unload an opened scene from the Unity Editor (asynchronously via `SceneManager.UnloadSceneAsync`). Use 'scene-list-opened' to find the scene name first.

Destroy a GameObject (and all nested children) in the currently opened Prefab or active Scene. Returns the destroyed GameObject's name, path, and instance ID for confirmation. Use 'gameobject-find' to locate the target first.

Render a target GameObject from a chosen camera angle with optional layer-based isolation, configurable background (solid/skybox/transparent), multi-light setup via JSON, and Composite (2x2 Front/Right/Back/Top) mode. Returns a PNG image. When isolated=true, inactive children may briefly fire OnEnable — see the body for side-effect notes.
