AI-Skill-Tools For Unity

AI-Skill-Tools is an HTTP API server framework designed for AI assistants to call autonomously, running inside the Unity environment. AI assistants control the Unity Editor or runtime applications through standard REST APIs (GET/POST + JSON), with no session management and no SSE, just pure stateless request/response mode.

Core features:

• Automatic Type Support: Built-in serialization and parameter expansion for Unity basic types (Vector2/3/4 ,Quaternion ,Bounds ,Rect ,Ray ,Color ,Matrix4x4 , etc.).
• Custom Type Support: Supports complex parameters like nested objects and object arrays through dual JsonProperty + ApiArgument attribute annotations.
• Attribute-Driven Development: Annotate tool methods with HttpServe and parameters with ApiArgument. The framework auto-generates JSON Schema and routes.
• Instance Tool Registration: Supports registering tools separately for multiple instances of the same class, with tool names formatted as {instanceId}.{methodName}
• Skill Export: One-click export of all registered tools as a standard AI Agent Skill file (SKILL.md format), so AI assistants can read and call them directly

We also provide AGENTS.md, which you can use with your own AI agents for secondary development as you wish.
