SemanticPluginForge.Core 1.0.1

SemanticPluginForge

SemanticPluginForge is a .NET library for extending Semantic Kernel plugins with metadata support.

Installation

You can install the SemanticPluginForge package via NuGet:

dotnet add package SemanticPluginForge

Usage

Implementing a Custom Metadata Provider

Implement the IPluginMetadataProvider interface. The following code is a sample provider that overrides the description of a function from the TimePlugin.

public class CustomTimeYearMetadataProvider : IPluginMetadataProvider
{
    public PluginMetadata? GetPluginMetadata(KernelPlugin plugin) => null;

    public FunctionMetadata GetFunctionMetadata(KernelPlugin plugin, KernelFunctionMetadata metadata) =>
        plugin.Name == "TimePlugin" && metadata.Name == "Year"
            ? new FunctionMetadata(metadata.Name) { Description = "Get the current year in 4-digit number format." }
            : null;
}

Registering the Metadata Provider

Register the custom metadata provider with the service collection.

services.AddSingleton<IPluginMetadataProvider, CustomTimeYearMetadataProvider>();

Adding Plugins with Patched Metadata

Use the extension methods from this library to add plugins with patched metadata.

var kernelBuilder = services.AddKernel();
kernelBuilder.Plugins.AddFromTypeWithMetadata<TimePlugin>();
