Prompt Composability | Langfuse 简体中文

As you create more prompts, you will often find yourself using the same snippets of text or instructions in multiple prompts. To avoid duplication, you can compose prompts by referencing other prompts.

Why Use Composed Prompts?

Create modular prompt components that can be reused across multiple prompts
Maintain common instructions, examples, or context in a single place
Update dependent prompts automatically when base prompts change

Get started

Langfuse UI

SDKs/API

When creating the prompt via the Langfuse UI, you can use the Add prompt reference button to insert a prompt reference into your prompt.

You can reference other text prompts in your prompts the following format:

@@@langfusePrompt:name=PromptName|version=1@@@

You can also use a label instead of a specific version for dynamic resolution:

@@@langfusePrompt:name=PromptName|label=production@@@

Not exactly what you need? Consider these similar features:

Variables for inserting dynamic text into prompts
Message placeholders for inserting arrays of complete messages instead of strings
