README

U3D Dev Tools AI

Unity Package Manager tools for AI-assisted Unity Editor automation.

This repository is distributed as one UPM package:

com.sputnicyoji.u3d-dev-tools-ai

It contains local Editor services and agent-side clients so an AI coding agent can run Unity tests, inspect Editor state, diagnose Lua runtime state through a project adapter, and sync agent skills into a Unity project.

Install

Add the package from Git URL:

{
  "dependencies": {
    "com.sputnicyoji.u3d-dev-tools-ai": "https://github.com/sputnicyoji/U3D-Dev-Tools-AI.git?path=/Packages/com.sputnicyoji.u3d-dev-tools-ai#u3d-dev-tools-ai-v0.2.8"
  }
}

For local development, replace `` with an absolute path on your workstation:

{
  "dependencies": {
    "com.sputnicyoji.u3d-dev-tools-ai": "file:/Packages/com.sputnicyoji.u3d-dev-tools-ai"
  }
}

If the repository is private, configure Git authentication before opening Unity. Use an SSH key or a Git credential helper. Do not put access tokens in `manifest.json`.
