Examples

Adding filters with lambdas:

using LMKit.TextGeneration.Filters;

var pipeline = new FilterPipeline();


// Prompt logging
pipeline.AddPromptFilter(async (ctx, next) =>
{
Console.WriteLine($"[Prompt] {ctx.Prompt}");
await next(ctx);
Console.WriteLine($"[Done] {ctx.Result?.GeneratedTokenCount} tokens");
});


// Completion telemetry
pipeline.AddCompletionFilter(async (ctx, next) =>
{
await next(ctx);
Console.WriteLine($"[Quality] {ctx.Result?.QualityScore:F2}");
});


// Tool call logging
pipeline.AddToolInvocationFilter(async (ctx, next) =>
{
Console.WriteLine($"[Tool] {ctx.ToolCall.Name}");
await next(ctx);
});

Remarks

These methods wrap lambda delegates into the corresponding filter interfaces, allowing you to add filters without creating a dedicated class.
