## Core Systems

### Skin System
* Fetches player skins directly from Mojang's API using usernames.
* Extracts skin data (value and signature) and applies it to the NPC's appearance.
* Caches skin data locally in `skins.yml` to minimize API requests and improve performance.
* All skin fetching operations are performed asynchronously to prevent server lag.
* Supports updating or clearing NPC skins via commands.

### Persistence
* **NPC Data**: All NPC configurations (UUID, name, location, skin data, entity type, path points, equipment, behavior settings, interaction details) are stored persistently in `npcs.yml`.
* **Skin Cache**: Downloaded skin data is cached in `skins.yml`.
* **Automatic Loading**: All NPCs are automatically loaded and spawned when the plugin starts.

### Command Handling
* A robust command system with clear subcommands for all NPC management tasks.
* Includes full tab completion for ease of use.
* Comprehensive error handling for invalid commands or missing selections.

### Interaction Triggers
* Supports various methods for players to interact with NPCs: right-click, left-click, and proximity detection.
* When triggered, NPCs can display dialogue and execute server commands.

### Pathfinding & Movement
* NPCs can be configured with patrol paths consisting of multiple waypoints.
* NPCs can be commanded to follow specific players.

### Equipment Management
* A dedicated graphical user interface (GUI) allows server admins to visually equip NPCs with armor and items.
