Unity

new-unity-project

Guides creating a new Unity project, gathering concept, platforms, and monetization before setting up the project, source control, and packages. Use when the user asks to start a new game or prototype.

optimize-audio

Optimizes audio memory, CPU cost, and playback quality through import settings and mixer configuration. Use when asked to reduce audio memory or Audio Mixer CPU cost, change clip Load Types, sample rates or codecs, or force 3D audio to mono.

optimize-text-mesh-pro

Optimizes TextMeshPro rendering, memory, and font setup, including font asset stacks, fallback atlases, SDF quality, and worldspace text. Use when the user asks about TMP fonts, CJK or multilingual text, or text performance.

optimize-web

Optimizes Unity WebGL and WebGPU builds for smaller downloads and faster load. Use when a web build is too large or stutters, or the user asks about compression, stripping, shader variants, or web profiling.

physics-3d-collision

Diagnoses 3D PhysX collision and trigger problems. Use when OnCollisionEnter or OnTriggerEnter doesn't fire, objects pass through each other, raycasts miss, or a MeshCollider misbehaves. Also answers 2D and DOTS physics best-effort if no dedicated skill is available.

setup-multiplayer-services

Guides real-time online multiplayer with Unity Multiplayer Services. Use when the user asks about network topology, hosting, matchmaking, or session-based play such as rooms, parties, and lobbies, not backend features.

setup-vivox-voice-chat

Adds and configures in-game voice and text chat with Unity Vivox. Use when the user asks about voice chat, microphone permissions, mute controls, proximity voice, team and lobby channels, or direct messages.

shader-graph-create-custom-node

Generates custom Shader Graph nodes from HLSL code. Use when the user wants a new Shader Graph node or to make existing HLSL work as a reflected function node.

sprite-editor

Edits Unity sprite rectangles, borders, pivots, outlines, and slicing by generating C# scripts. Use when the user works with sprite sheets or sprite slicing.

sprite-segment-3x3grid

Segments a Sprite texture into a 3x3 grid and outputs a pattern of cells matching the center cell's color. Use when the user asks to analyze or document a sprite's structure or color distribution.

tilemap-palette-create

Creates a Tile Palette asset with a rectangular, hexagonal, or isometric Grid layout. Use when the user wants to organize tiles for 2D level design.

tilemap-ruletile-createempty

Creates an empty RuleTile, HexagonalRuleTile, or IsometricRuleTile asset. Use only when the user wants a blank RuleTile and provides no sprites; with sprites or terrain art, use tilemap-ruletile-createfromsegment.

tilemap-ruletile-createfromsegment

Creates RuleTiles from existing terrain or edge sprites so tiles auto-tile while painting, and converts sprite-segment-3x3grid output patterns into TilingRules. Use when the user wants sprites to connect correctly or to define tile neighbor rules, and provides sprites as input.

ui

Routes Unity UI requests to the right framework skill (UI Toolkit, uGUI, or IMGUI) and answers UI comparison questions. Use for menus, HUDs, panels, or editor UI when the request doesn't name a framework. Consult before writing any UI code.

ui-imgui

Generates and modifies Unity IMGUI editor code such as EditorWindows, custom Inspectors, PropertyDrawers, and OnGUI scripts. Use for IMGUI or OnGUI or maintaining existing IMGUI code.

ui-ugui

Understands, edits, and generates Unity uGUI Canvas hierarchies, RectTransforms, Layout Groups, and prefab UI. Use for requests involving Canvas, uGUI, RectTransform, or prefab UI files.

ui-uitk

Understands, edits, and generates Unity UI Toolkit UXML and USS with flex layouts. Use for requests involving UI Toolkit, UIElements, UIDocument, PanelSettings, custom elements, or UI runtime binding.

unity-cli

Controls the Unity Editor and projects from the command line, driving a running Editor to edit scenes and assets or run C#. Use when asked to install or manage Editors, licenses, or projects, set up version control, build, test, configure the Unity MCP server, or run any unity command.

unity-package-management

Adds, removes, upgrades, and discovers Unity (UPM) packages from outside the Editor. Use for headless or CI package installs, verifying package IDs and versions, or choosing which packages a game needs. The Unity CLI doesn't manage packages.

urp-postprocessing

Sets up, configures, and debugs URP post-processing with the Volume framework. Use for bloom, tonemapping, color adjustments, depth of field, vignette, or other Volume overrides.

validate-urp-render-graph-renderer-feature

Reviews a Unity 6 URP ScriptableRendererFeature that uses the Render Graph API, checking resource wiring, material binding, execution structure, and best practices. Use to validate a renderer feature.
