SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams modify Unity asset files safely by enforcing inspection steps and restricting edits to the Assets/ folder, avoiding changes in Packages/.

Core Features & Use Cases

  • Safely modify asset content by targeting a specific asset and applying new data through the assets-modify tool.
  • Enforce pre-modification inspection with assets-get-data to understand asset structure before making changes.
  • Use Case: Update a ScriptableObject or Material in the project while ensuring Packages/ remain untouched.

Quick Start

Use assets-get-data to inspect the asset structure, then run unity-mcp-cli run-tool assets-modify with the assetRef and content to apply the change.

FAQPage Schema
How do I safely modify Unity asset files during development?▼

You can modify Unity asset files by supplying an asset reference and new content through unity-mcp-cli, which validates inputs and executes changes strictly within the Assets/ directory for safe in-place updates.

What is the best way to update a ScriptableObject or Material in a Unity project?▼

Updating a ScriptableObject or Material requires inspecting the asset structure first, then executing a targeted modification with the asset reference and new content schema to safely apply changes within the project.

How does the assets-modify tool enforce safety when changing Unity assets?▼

Safety is enforced through input validation, required assetRef and content schema checks, and directory restrictions that forbid modifications in Packages/, ensuring only safe, targeted updates within Assets/ occur.

Can I use unity-mcp-cli to modify assets in the Packages folder?▼

No, unity-mcp-cli explicitly forbids modifications in the Packages/ folder, restricting all asset file updates to the Assets/ directory to ensure safe, targeted changes during development workflows.

What should I do before modifying a Unity asset file?▼

Before modifying a Unity asset file, inspect the asset structure using assets-get-data to understand its content schema, then prepare the new data and a valid asset reference for the modification workflow.

Why are my Unity asset modifications not applying correctly through automation?▼

Modifications may fail if the required assetRef and content schema are not properly validated, or if the target file is located in Packages/ instead of Assets/, where the tool restricts changes to prevent unsafe modifications.
