Protocol for data structures that can be converted into prompts for LLMs.

Implementing this protocol allows any struct to be convertible to a string prompt via Jido.AI.Promptable.to_prompt/1.

Examples

defimpl Jido.AI.Promptable, for: MyApp.User do
  def to_prompt(user) do
    "User #{user.name} is #{user.age} years old"
  end
end

user = %MyApp.User{name: "Alice", age: 30}
Jido.AI.Promptable.to_prompt(user) #=> "User Alice is 30 years old"
