version: "1.0.2" name: unity-asset description: Manage Unity AssetDatabase operations

Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Organizing project assets
• Importing or relocating files
• Querying asset metadata
• Scripting AssetDatabase operations
• 整理工程资源、导入或移动文件、查询资源元数据、脚本化 AssetDatabase 操作

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

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.

asset_import_batch

Import multiple external files.

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.

asset_delete_batch

Delete multiple assets.

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.

asset_move_batch

Move multiple assets.

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.

asset_find

Find assets by search filter.

Search Filter Syntax:

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

asset_create_folder

Create a folder in the project.

asset_refresh

Refresh the AssetDatabase after external changes.

No parameters.

asset_get_info

Get information about an asset.

asset_reimport

Force reimport of an asset.

asset_reimport_batch

Reimport multiple assets matching a pattern.

asset_set_labels

Set labels on an asset (overwrites existing labels).

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

asset_get_labels

Get the labels currently attached to an asset.

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

Exact names, parameters, defaults, and returns are defined by GET /skills/schema or unity_skills.get_skill_schema(), not by this file.
