Prompt tool

The prompt tool in prompt flow offers a collection of textual templates that serve as a starting point for creating prompts. These templates, based on the Jinja2 template engine, facilitate the definition of prompts. The tool proves useful when prompt tuning is required prior to feeding the prompts into the large language model in prompt flow.

It also presents a menu of options for the user to choose from. Depending on whether the user_name variable is provided, it either addresses the user by name or uses a generic greeting.
