What it does
Assets Prefab Create is an agent skill from IvanMurzak/Unity-MCP. 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.
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. 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.

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

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
Assets Prefab Create loads about 1.6k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 389 words of instructions outside code blocks.
Always· name and description, kept in context so the agent knows when to use it
~72
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
assets-prefab-create
description
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.
Assets / Prefab / Create
Create a prefab from a GameObject in the current active scene. The prefab will be saved in the project assets at the specified path. Creates folders recursively if they do not exist. If the source GameObject is already a prefab instance and 'connectGameObjectToPrefab' is true, a Prefab Variant is created automatically. To create a Prefab Variant from an existing prefab asset, provide 'sourcePrefabAssetPath' instead of 'gameObjectRef'. Use 'gameobject-find' tool to find the target GameObject first.
Inputs (mutually exclusive sources)
prefabAssetPath — required. Must start with Assets/ and end with .prefab.
gameObjectRef — scene GameObject to convert (or to seed a Prefab Variant from when it is already a prefab instance).
sourcePrefabAssetPath — existing prefab asset to seed a Prefab Variant from. Cannot be combined with gameObjectRef.
connectGameObjectToPrefab (default true) — when sourcing from a scene GameObject, connect the scene object to the new prefab asset (becoming a prefab instance). Ignored for sourcePrefabAssetPath (always creates a variant).
Behavior
Creates intermediate folders along prefabAssetPath if they don't already exist. Returns an AssetObjectRef pointing at the new prefab asset.
If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead.

Input
Name
Type
Required
Description
prefabAssetPath
string
Yes
Prefab asset path. Should be in the format 'Assets/Path/To/Prefab.prefab'.
gameObjectRef
any
No
Reference to a scene GameObject to create the prefab from. If the GameObject is already a prefab instance, a Prefab Variant is created when 'connectGameObjectToPrefab' is true. Optional if 'sourcePrefabAssetPath' is provided.
sourcePrefabAssetPath
string
No
Path to an existing prefab asset to create a Prefab Variant from (e.g. 'Assets/Prefabs/Base.prefab'). When provided, a temporary instance is created, saved as a Prefab Variant, and cleaned up. Optional if 'gameObjectRef' is provided.
connectGameObjectToPrefab
boolean
No
If true, the scene GameObject will be connected to the new prefab (becoming a prefab instance). If the source is already a prefab instance, this creates a Prefab Variant. If false, the prefab asset is created but the scene GameObject remains unchanged. Ignored when 'sourcePrefabAssetPath' is used (always creates a variant).
