What it does
Gameobject Create is an agent skill from IvanMurzak/Unity-MCP. Create a new GameObject in the currently opened Prefab or active Scene, optionally parented under another GameObject and pre-positioned. Pass primitiveType to spawn a Unity primitive (Cube, Sphere, etc.) instead of an empty GameObject.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Game development. It works with Model Context Protocol. The repository describes itself as: AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C method may be turned into a… The licence is Apache-2.0.
When your agent uses it
Tasks that involve Game development
Example prompts
“/gameobject-create”
Requirements
Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 4c8056f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gameobject Create loads about 1.6k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 239 words of instructions outside code blocks.
Always· name and description, kept in context so the agent knows when to use it
~64
When it runs· the whole SKILL.md, loaded when a task matches
~1.6k
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name
gameobject-create
description
Create a new GameObject in the currently opened Prefab or active Scene, optionally parented under another GameObject and pre-positioned. Pass `primitiveType` to spawn a Unity primitive (Cube, Sphere, etc.) instead of an empty GameObject.
GameObject / Create
Create a new GameObject in opened Prefab or in a Scene. If needed - provide proper 'position', 'rotation' and 'scale' to reduce amount of operations.
Inputs
name — required non-empty name.
parentGameObjectRef (optional) — when provided, the new GameObject is parented under this one (SetParent(parent, worldPositionStays: false)); otherwise it's created at scene/prefab root.
position / rotation / scale — optional transform; default to zero / zero / one.
isLocalSpace — when true, applies the transform in local space relative to the parent.
primitiveType (optional) — when set, the GameObject is created via GameObject.CreatePrimitive (adds the appropriate renderer/collider for the primitive shape).
If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead.
Read the /unity-initial-setup skill for detailed installation instructions.
