# Extract the Prompt Template Engine from Semantic Kernel core
|
|
|
|
## Context and Problem Statement
|
|
|
|
The Semantic Kernel includes a default prompt template engine which is used to render Semantic Kernel prompts i.e., `skprompt.txt` files. The prompt template is rendered before being send to the AI to allow the prompt to be generated dynamically e.g., include input parameters or the result of a native or semantic function execution.
|
|
To reduce the complexity and API surface of the Semantic Kernel the prompt template engine is going to be extracted and added to it's own package.
|
|
|
|
The long term goal is to enable the following scenarios:
|
|
|
|
1. Implement a custom template engine e.g., using Handlebars templates. This is supported now but we want to simplify the API to be implemented.
|
|
2. Support using zero or many template engines.
|
|
|
|
## Decision Drivers
|
|
|
|
* Reduce API surface and complexity of the Semantic Kernel core.
|
|
* Simplify the `IPromptTemplateEngine` interface to make it easier to implement a custom template engine.
|
|
* Make the change without breaking existing clients.
|
|
|
|
## Decision Outcome
|
|
|
|
* Create a new package called `Microsoft.SemanticKernel.TemplateEngine`.
|
|
* Maintain the existing namespace for all prompt template engine code.
|
|
* Simplify the `IPromptTemplateEngine` interface to just require implementation of `RenderAsync`.
|
|
* Dynamically load the existing `PromptTemplateEngine` if the `Microsoft.SemanticKernel.TemplateEngine` assembly is available.
