---

## 🌟 Overview

LLM Connect brings modern AI assistance into Luanti worlds.
Players and developers can interact with a Large Language Model directly in-game to:

- ask questions
- generate Lua code
- analyze or refactor scripts
- assist with WorldEdit building tasks
- experiment with sandboxed Lua execution

The mod combines an **AI chat interface**, a **Smart Lua IDE**, and **LLM-assisted building tools** into a single integrated workflow.

---

## ✨ Core Features

### 🤖 AI Chat Interface

Interact with a Large Language Model directly inside Luanti.

Features include:

- In-game chat GUI
- conversation context handling
- player and world information awareness
- configurable prompts and system instructions
- support for OpenAI-compatible APIs

The chat system automatically includes contextual information such as:

- player position
- installed mods
- selected materials
- server environment

---

### 💻 Smart Lua IDE

LLM Connect includes a fully integrated **AI-assisted Lua development environment**.

Capabilities include:

- AI code generation from natural language prompts
- semantic code explanation
- automated refactoring
- code analysis
- interactive editing interface
- integration with the game environment

Developers can experiment with Lua snippets directly inside the game.

---

### 🧪 Sandboxed Code Execution

Lua code can be executed inside a controlled environment.

Security features include:

- privilege-based execution access
- sandboxed runtime
- optional whitelist restrictions
- prevention of filesystem access

Execution results are returned to the IDE interface for inspection.

---

### 🏗️ WorldEdit AI Assistant

LLM Connect can assist with building tasks using WorldEdit.

Examples:

- structure generation prompts
- building suggestions
- node/material selection
- architectural transformations

The system can combine:

- player position
- selected materials
- worldedit context

to produce context-aware instructions.

---

### 🧱 Material Selection Tools

The mod includes a **material picker** interface that helps the AI understand:

- available nodes
- building palettes
- player selections

This improves the quality of building-related prompts.

---

| `llm_ide` | Access to the Smart Lua IDE |
| `llm_dev` | Sandbox Lua execution |
| `llm_root` | Full administrative control |

Server operators should grant privileges carefully.

---
