unity-asset

name	unity-asset
description	Manage the Unity AssetDatabase — import, delete, move/rename, duplicate, find, get info, and create assets. Use when organizing project assets, importing or relocating files, querying asset metadata, or scripting AssetDatabase operations, even if the user just says "资源" or "资产". 管理 Unity AssetDatabase(导入、删除、移动/重命名、复制、查找、获取信息、创建资源);当用户要整理工程资源、导入或移动文件、查询资源元数据时使用。

Unity Asset Skills

BATCH-FIRST: Use *_batch skills when operating on 2+ assets.

Operating Mode

• Approval：本模块 Mixed —— asset_find / asset_get_info / asset_get_labels 标 SkillMode.SemiAuto，可直接执行；写类 skill (asset_move / asset_move_batch / asset_duplicate / asset_create_folder / asset_refresh / asset_reimport* / asset_set_labels) 走默认 SkillMode.FullAuto，需 grant。
• Auto / Bypass：FullAuto 直接执行。
• 含 NeverInSemi 高危 skill：asset_import (标 RiskLevel = "high" —— 写入项目)；asset_delete / asset_delete_batch (Operation.Delete)。这些在 Approval/Auto 下返 MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。

DO NOT (common hallucinations):

• asset_create does not exist → use asset_create_folder (folders), material_create (materials), script_create (scripts)
• asset_rename does not exist → use asset_move with new path
• asset_search does not exist → use asset_find with searchFilter syntax (e.g. t:Texture2D player)
• asset_copy does not exist → use asset_duplicate

Routing:

• For texture/model/audio import settings → use importer module (SkillMode.FullAuto)
• For material creation → use material module (SkillMode.FullAuto)
• For script creation → use script module

Skills Overview

Single Object	Batch Version	Use Batch When
asset_import	asset_import_batch	Importing 2+ files
asset_delete	asset_delete_batch	Deleting 2+ assets
asset_move	asset_move_batch	Moving 2+ assets

No batch needed:

• asset_duplicate - Duplicate single asset
• asset_find - Search assets (returns list)
• asset_create_folder - Create folder
• asset_refresh - Refresh AssetDatabase
• asset_get_info - Get asset information
• asset_reimport - Force reimport asset
• asset_reimport_batch - Reimport multiple assets

Skills

asset_import

Import an external file into the project.

Parameter	Type	Required	Description
sourcePath	string	Yes	External file path
destinationPath	string	Yes	Project destination

asset_import_batch

Import multiple external files.

Parameter	Type	Required	Default	Description
items	json string	Yes	-	JSON array of per-item objects (see example below)

items currently expects a JSON string, not a native array.

Returns: {success, totalItems, successCount, failCount, results: [{success, sourcePath, destinationPath}]}

import json

unity_skills.call_skill("asset_import_batch", items=json.dumps([
    {"sourcePath": "C:/Downloads/tex1.png", "destinationPath": "Assets/Textures/tex1.png"},
    {"sourcePath": "C:/Downloads/tex2.png", "destinationPath": "Assets/Textures/tex2.png"}
]))

asset_delete

Delete an asset from the project.

Parameter	Type	Required	Description
assetPath	string	Yes	Asset path to delete

asset_delete_batch

Delete multiple assets.

Parameter	Type	Required	Default	Description
items	json string	Yes	-	JSON array of per-item objects (see example below)

items currently expects a JSON string, not a native array.

Returns: {success, totalItems, successCount, failCount, results: [{success, path}]}

import json

unity_skills.call_skill("asset_delete_batch", items=json.dumps([
    {"path": "Assets/Textures/old1.png"},
    {"path": "Assets/Textures/old2.png"}
]))

asset_move

Move or rename an asset.

Parameter	Type	Required	Description
sourcePath	string	Yes	Current asset path
destinationPath	string	Yes	New path/name

asset_move_batch

Move multiple assets.

Parameter	Type	Required	Default	Description
items	json string	Yes	-	JSON array of per-item objects (see example below)

items currently expects a JSON string, not a native array.

Returns: {success, totalItems, successCount, failCount, results: [{success, sourcePath, destinationPath}]}

import json

unity_skills.call_skill("asset_move_batch", items=json.dumps([
    {"sourcePath": "Assets/Old/mat1.mat", "destinationPath": "Assets/New/mat1.mat"},
    {"sourcePath": "Assets/Old/mat2.mat", "destinationPath": "Assets/New/mat2.mat"}
]))

asset_duplicate

Duplicate an asset.

Parameter	Type	Required	Description
assetPath	string	Yes	Asset to duplicate

asset_find

Find assets by search filter.

Parameter	Type	Required	Default	Description
searchFilter	string	Yes	-	Search query
limit	int	No	50	Max results to return

Search Filter Syntax:

Filter	Example	Description
t:Type	t:Texture2D	By type
l:Label	l:Architecture	By label
name	player	By name
Combined	t:Material player	Multiple filters

Returns: {count, totalFound, assets: [{path, name, type}]}

asset_create_folder

Create a folder in the project.

Parameter	Type	Required	Description
folderPath	string	Yes	Full folder path

asset_refresh

Refresh the AssetDatabase after external changes.

No parameters.

asset_get_info

Get information about an asset.

Parameter	Type	Required	Description
assetPath	string	Yes	Asset path

asset_reimport

Force reimport of an asset.

Parameter	Type	Required	Description
assetPath	string	Yes	Asset path to reimport

asset_reimport_batch

Reimport multiple assets matching a pattern.

Parameter	Type	Required	Description
searchFilter	string	No	AssetDatabase search filter (default *)
folder	string	No	Folder root to search (default Assets)
limit	int	No	Max assets to reimport (default 100)

asset_set_labels

Set labels on an asset (overwrites existing labels).

Parameter	Type	Required	Description
assetPath	string	Yes	Asset path
labels	string	Yes	Comma-separated labels (e.g. "ui,icon,hud"). Empty entries are dropped

Returns: {success, assetPath, labels: [...]}

asset_get_labels

Get the labels currently attached to an asset.

Parameter	Type	Required	Description
assetPath	string	Yes	Asset path

Returns: {success, assetPath, labels: [...]}

Minimal Example

import unity_skills

# GOOD: 1 API call instead of 4
unity_skills.call_skill("asset_move_batch", items=[
    {"sourcePath": "Assets/tex1.png", "destinationPath": "Assets/Textures/tex1.png"},
    {"sourcePath": "Assets/tex2.png", "destinationPath": "Assets/Textures/tex2.png"},
    {"sourcePath": "Assets/tex3.png", "destinationPath": "Assets/Textures/tex3.png"},
    {"sourcePath": "Assets/tex4.png", "destinationPath": "Assets/Textures/tex4.png"}
])

Best Practices

1. Organize assets in logical folders
2. Use consistent naming conventions
3. Refresh after external file changes
4. Use search filters for efficiency
5. Backup before bulk delete operations
