PromptManager class

Package:
@microsoft/teams-ai

A filesystem based prompt manager.

Remarks

The default prompt manager uses the file system to define prompts that are compatible with Microsoft's Semantic Kernel SDK (see: https://github.com/microsoft/semantic-kernel)

Each prompt is a separate folder under a root prompts folder. The folder should contain the following files:

  • "config.json": Required. Contains the prompts configuration and is a serialized instance of PromptTemplateConfig.
  • "skprompt.txt": Required. Contains the text of the prompt and supports Semantic Kernels prompt template syntax.
  • "actions.json": Optional. Contains a list of actions that can be called by the prompt.

Prompts can be loaded and used by name and new dynamically defined prompt templates can be registered with the prompt manager.
