This seems like an equivalent to Mustache or Handlebars except for programmatically building prompts rather than HTML? For example, I may be building a text game, and I may have to get rules, state, character specs, etc. Then I may have to load these things into a document as part of a prompt for the LLM to consume. Simple, as others mentioned. But still nice to have something to reach for rather than building this myself. Edit: And thanks! This is timely.
