A highly abstracted pattern this interface priorities users making selections from a set of available controls which have variables mapped to pre existing prompt snippets.
These selected snippets are then compiled into a cohesive quality prompt much faster & containing far more detail than a user could otherwise create.
While the direct text input method is also provided it plays a second their role representing a more brief part of the final collateral & submitted prompt..
Like all highly abstracted interfaces this pattern allows users to quickly author a prompt far behind the complexity possible with any direct text input.
Users who know & understand the meaning of the available options can benefit not only from the initial speed of selection but also the rapid experimentation possible by quickly manipulating and generating various configurations..
The key consideration here is being able to define the appropriate options to present & be confident in their effectiveness for your users context.
The complexity of these options can expand & contract as needed. Even a simple set of options can provide a wide variety of output possibilities. For example 3 inputs with 3 options can produce 27 possible prompt variations.
For larger sets of inputs some conditional logic may be required to show or hide further inputs based on previous selections. This would serve to (A) Minimize the complexity for users through progressive disclosure & (B) To ensure a cohesive prompt once compiled by only showing logically dependent inputs when appropriate..
