AI Use Case Walkthrough: Building Marketing Software Part 2: Library Construction

In today’s episode, you’ll discover how to build a library of best practices for your AI-powered software project, using the Trust Insights RAPPEL framework. You’ll learn how to leverage generative AI tools like Google’s Gemini or Anthropic’s Claude to define the optimal technologies and coding practices for your application, even if you are not a technical expert. You’ll gain valuable insights into creating robust, high-performance code specifically tailored for web-based entertainment applications. This crucial step ensures that your AI model has the right guidelines to follow, setting you up for success in the next phases of development.

This is part two in our series of an AI use case walkthrough, building software for the non-technical person like the marketer. In part one, we did the requirements gathering for our app to walk through all the considerations that we would need to build this app. As a reminder, we’re building kind of a fun puzzle game. So in part two, we’re going to pick up where we left off with library construction. I’m using Google’s Gemini in AI Studio, but again, you’re free to use the AI tool of your choice, ChatGPT.

I would say for the average non-technical marketer, your best tool of choice would probably be Anthropic’s Claude because it’s really good at coding. If you’re going to be building a big app, then probably you’re going to use Google Gemini because it has the largest working memory. Today, we’re going to start building the library construction, and what we’re specifically talking about here is building the best practices documents, the knowledge blocks like we saw in part one for the code. This is important because we want to specify what are really good best practices for writing this kind of software, and then when we start writing it, the AI model will have those guidelines to follow, things like error tracking and logging and stuff like that.

To do this, we’re going to use the Trust Insights RAPPL framework: role, action, prime, prompt, evaluate, and learn, as we did in the previous steps. So let’s go ahead and go into, I’m going to pick up where we left off. We’ve already done the requirements gathering. What I want to say, do next is I need to know what kind of best practices library to work with. So far in this app, we are already almost 18,000 tokens, which is what, about 14,000 words in. I’m going to start by saying, what are the best technologies, libraries, frameworks, and languages best suited to meet our requirements for developing this app?

As you recall from the previous one, I’m going to save those requirements as markdown. When you do this and you save it in your prompt library, you can see that you get a really, really nice extensive list of this. This is what the thing is going to do. The author here is going to be Gemini and Trust Insights. Boy, do you think it’s October 26, 2023? It is not. This is January 12, 2025. That tells you where the knowledge cutoff of this thing is. All right. So this is my, in my prompt library now, I’ve stored the requirements for this app. Now I’m going to ask it, what technologies are the best fit for this?

We’re going to ask this question, get the answer, answers and then build out the best practices library. Client-side HTML5, CSS, JavaScript, framework React for the user interface, Emoji Picker for React, UI components, Material. Let’s see, server-side Node.js for this minimal service, I component, framework Express.js, SQLite for the database, and JSON for the puzzles, and NPM or Yarn for managing project dependencies, Webpack or Parcel, hosting, Vercel, AWS, Netlify. I’m just going to stick out on my website. Analytics, GA4. Testing, React Testing Library.

So these are all the potential technologies. It says the stack summary, React and so on and so forth. Say, great, we are going to standardize on the React Node approach given the choices. Show me now the revised tech stack. We’re going to use React, Node, SQLite. So that is front-end, back-end, and database. So now we get a much more focused list of all the things that we’re going to be doing. Now our next step is to start building out our best practices for these languages.

We’re going to start by saying, next, let’s do the role. You are an expert JavaScript developer skilled in Node, React, and web-based application development. Today, we’re going to isolate best practices for coding in React and Node and Node. What do you know about general best practices for creating robust, high-performance, high-speed, resource-efficient code in React and Node specific to web-based entertainment applications? So really what I’m doing here is I am just parroting back what the tool set or are a tool choices of saying, hey, what do you think, what are the best practices here?

What we’re going to be doing is we’re going to distill this down as we did in part one of taking all these ideas and things that typically go wrong and expert tips and tricks for both React and Node into a guide, into a knowledge block. So it’s spitting out that now. So I’m going to say, what are common mistakes in React and Node for web-based games that less skilled developers often make? I’m going to wait on this because I want to take this section here, and I’m going to put this in my comprehensive best practices guide instead of having it summarized because I don’t want to lose any of this valuable information.

I’m going to just copy and paste all three chunks. Note that we’re not coding. There’s zero coding happening here. This is literally just copying and pasting, but we’re asking questions to have the model spit out its known best practices for these languages. If I wanted you, I could take maybe the documentation from the React website or the Node.js website and actually feed that in as training data for this as well. That would be a way to get at even more great ideas. So I’m going to put in the React best practices and the Node best practices, and now I’m going to ask that second follow-up question.

We’re going to let it talk, and then we’re going to, while it’s talking, we’re going to write the third prompt which is, what are some expert tips and tricks in React and Node for web-based games, tricks of the trade, uncommon knowledge and approaches that we have not discussed yet? Okay, so it’s coming up with our our things to avoid guide. All right. So it has spit out the things to avoid guide. I’m now going to copy that, put that in my prompt library. You’ll see here, I’m going to just put some headings in to make this a little easier to see.

So there’s our best practices for in general. Here are our mistakes to avoid, and then we’re going to have React and Node game development, expert tips and tricks. Let’s see how we’re doing over here. Still coming up with things. All right. Our tips and tricks are done. So now we’re going to copy that, go to my prompt library, paste that right in, trim out a little bit of the the fluffy narrative. What do we have? We have a gigantic set of best practices for this exact application. Now, here’s the question, what do you do with this?

Well, what we do with this is we use this as system instructions. So in Claude, you could use system instructions. In ChatGPT, you can use it as system instructions, and of course in Gemini, you can do the same thing. I’m going to create a new prompt now, and I’m going to take that big, huge document that I just did, and I’m going to put the entire thing in. That is about 5,000 words of best practices, but what we’ve done is we’ve preloaded our AI to now be an expert coder in this whole setup.

So what we’ve done in part two here is we have taken our, we’ve used generative AI to take our overall requirements and then build from those requirements our instructions for telling this model how it’s going to code, how it should code, the things that it should not do. So this is part two. Next, in part three, we’re going to start framing out the application to understand just how complicated this is going to get. In part four, we’re going to start building it, and then in part five, we’re going to talk about deploying it.
