ILangfusePromptClient

NexusLabs.Needlr.AgentFramework.Langfuse ¶

ILangfusePromptClient Interface¶

Fetches and creates prompts in Langfuse prompt management, so the prompt an eval runs against lives in Langfuse and the generations link to the exact version that was used.

public interface ILangfusePromptClient

Properties¶

ILangfusePromptClient.IsEnabled Property¶

Gets a value indicating whether prompt operations are performed. false when Langfuse is not configured, in which case GetPromptAsync(string, string, Nullable<int>, CancellationToken) returns null.

bool IsEnabled { get; }

Property Value¶

System.Boolean

Methods¶

ILangfusePromptClient.CreateTextPromptAsync(string, string, IEnumerable<string>, CancellationToken) Method¶

Creates a new version of a text prompt (creating the prompt if the name is new).

System.Threading.Tasks.Task<NexusLabs.Needlr.AgentFramework.Langfuse.LangfusePrompt> CreateTextPromptAsync(string name, string prompt, System.Collections.Generic.IEnumerable<string>? labels=null, System.Threading.CancellationToken cancellationToken=default(System.Threading.CancellationToken));

Parameters¶

name System.String

The prompt name.

prompt System.String

The prompt text.

labels System.Collections.Generic.IEnumerable<System.String >

Optional labels to apply (for example production).

cancellationToken System.Threading.CancellationToken

A cancellation token.

Returns¶

System.Threading.Tasks.Task<LangfusePrompt >
The created prompt version.

ILangfusePromptClient.GetPromptAsync(string, string, Nullable<int>, CancellationToken) Method¶

Fetches a managed prompt by name, optionally pinned to a label or version. With neither, the production label is used. Returns null when the prompt does not exist (or Langfuse is not configured).

System.Threading.Tasks.Task<NexusLabs.Needlr.AgentFramework.Langfuse.LangfusePrompt?> GetPromptAsync(string name, string? label=null, System.Nullable<int> version=null, System.Threading.CancellationToken cancellationToken=default(System.Threading.CancellationToken));
