assets-prefab-create — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited assets-prefab-create (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
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.
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).Creates intermediate folders along prefabAssetPath if they don't already exist. Returns an AssetObjectRef pointing at the new prefab asset.

| 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). |
