# Class-Based Agent Skills Sample

This sample demonstrates how to define **Agent Skills as C# classes** using `AgentClassSkill`
with **attributes** for automatic script and resource discovery.

## What it demonstrates

- Creating skills as classes that extend `AgentClassSkill`
- Using `[AgentSkillResource]` on properties to define resources
- Using `[AgentSkillScript]` on methods to define scripts
- Automatic discovery (no need to override `Resources`/`Scripts`)
- Using the `AgentSkillsProvider` constructor with class-based skills
- Overriding `SerializerOptions` for Native AOT compatibility

## Skills Included

### unit-converter (class-based)

A `UnitConverterSkill` class that converts between common units. Defined in `Program.cs`:

- `conversion-table` — Static resource with factor table
- `convert` — Script that performs `value × factor` conversion
