Mind Readings: Solving Real World Problems with Generative AI and Code, Part 1

This week we're going to do something a little bit different. We are going to sort of follow along as I make something using generative AI to solve a real problem. So let's start with what the problem is in this first part. My martial arts teacher, Mark Davis of the Boston Martial Arts Center, took my advice to start a Substack, which is great. He does a lot of publishing.

He publishes pretty much every day, which is uh really wonderful. I love that. And now he's asking how do I bring my Substack posts over to the Boston Martial Arts Center blog. I did a quick bit of Googling. No such thing exists.

There is no way to easily take the contents of a Substack and move them to a WordPress site. Well, it can't be that hard. If you think about it, Substack is basically a blog that has email functionality. It's it's like newsletter software, but it has things like RSS feeds and stuff. And WordPress, self-hosted WordPress has APIs.

So let's use generative AI to think through how we could solve this problem. So the first thing we need to do is start thinking out requirements. What do we want? A how how could we solve this problem? There's a bunch of different ways, but what's important is that it has to work for my teacher.

My teacher is not a highly technical person. He is an absolutely phenomenal martial artist and a wonderful teacher, but he's not a techno nerd like I am. So it has to be easy to use. It has to have a fair level of control to be able to set it and forget it, yes, but also to tune it. And it has to be as secure as possible, using as few external dependencies as possible.

So how would we do that? Well, we've start by writing requirements. So let's think this through. Today we're going to build the requirements for a piece of software, maybe a WordPress plugin, that will sync an RSS feed from Substack to a WordPress blog that is self-hosted on WP Engine. And you can see I'm using my voice to uh text typing uh tool here to start building out uh what we want to do.

The software could be a standard WordPress plugin compatible with self-hosted WordPress. The current version of WordPress, I believe, is 6.8.2. Substack has an RSS feed available at uh I believe it's slash feed. So this would be Boston Marshall Arts Center.substack.com slash feed. And it looks like I need to uh need to clean that up a little bit to take out the little transliterations there.

And let me just double check that that is in fact my teacher's actual uh Substack. Yes. All right, center Substack. That'd be embarrassing. That was in fact not.

Yes, sub a Boston Martial Arts Center Substack. Good. So that would be there. And that is his feed. The WordPress plugin should inspect the RSS feed using the built-in scheduler for WordPress, which I believe is WP cron, and should check once an hour for new items on the Substack RSS feed.

Once a new item is detected, the plugin should import the post, clean it up, make sure that there's no invalid HTML, and insert it into the blog of the WordPress site, setting it as a draft. The item title from the feed should become the blog post title. The configuration options should have something that allows us to programmatically determine what WordPress categories we should be using. Categories would include things like meditation, mindfulness, the martial arts, uh training, conditioning, Japanese history, Japanese culture, using basic pattern matching of keywords to determine which category a blog post should be in. The user should have the opportunity to change what keywords are detected and associated with each category and should be able to add new categories using the built-in WordPress categories feature and map those to the relevant keywords.

The user should have the option to import as drafts or import as published posts. So what I've done so far is put down a good number of the requirements Gemini. Now what we have to do is we have to take this. You can use Chat GPT. You can use Claude.

Doesn't really matter. They're all for this particular kind of project, they're all pretty much the same thing. I'm going to take what we've typed so far, and now I'm going to add in. Now, based on what I've provided so far, ask me one question and one question only at a time until you have enough information to build out a product requirements document. Remember that product requirements documents or PRDs contain user stories, an executive summary, functional requirements, non-functional requirements, and domain requirements.

And now we start the process of having the tool ask us what questions does it have that we have not provided answers for. Okay, let's see. The first question how should it handle images? Images should be imported into the WordPress media library. If a post on Substack is edited after it's been imported, should the plugin update the corresponding WordPress post?

Yes, if a post has been edited on Substack, the changes should be imported with WordPress. And the WordPress post should be moved back into draft status. Let's see, when a post is imported, which WordPress user should be assigned as its author. Substack posts often contain platform specific elements of like a share buttons, sections subscription forms. Yes, the plugin should automatically identify and remove those elements if there's no corresponding equivalent in WordPress and or standard HTML.

Actually, do we want that to be the case? Or do we want to go? No, don't. What the plugin should do is it should substitute those Substack specific things with a link back to the Substack website and a generic button saying subscribe to this Substack. That way, someone who finds the blog post on the WordPress site will click or tap on the like or the share or the subscribe feature from Word from Substack and go back to the Substack so that they can subscribe there.

We don't want to lose any potential subscribers. Let's see. Next question on initial setup. When the plugin is activated for the first time, it should definitely attempt to import all historical posts, but it should give the user the option to specify that in the configuration to import all historical posts or to import only posts published after the plugin's installation. When the plugin syncs with the WordPress MySQL database, it will use that database and create its own table to track things like synchronization.

Let's see. Post presentation. Should the plugin attempt to automatically set a WordPress featured image? Yes, it should. Let's see.

Um I don't know that it's done the user story. Let me specify a user story. The as a Substack user and WordPress blog owner, I need to synchronize my Substack posts with my WordPress blog so that my content appears on a property that I own, namely my WordPress site. So that if Substack ever went away, I would not lose all the content that I've worked so hard to publish. And here comes the product requirements document.

We have Substack sync for WordPress as a plugin. Good. Is there enough detail that a software product manager could manage this entire product and project from the PRD only? For example, does it specify recommended WordPress libraries or functions or features that would be most useful? Or PHP functions and features that would be most useful.

Or PHP libraries that could assist and help us from reinventing the wheel. Okay. Go ahead and publish the revised and upgraded PRD that contains all the technical recommendations in addition to all the previous details so that we have a complete and comprehensive PRD. Use the canvas to do this. This looks good.

Let's go ahead and turn it into a Google Doc. That way we have it A, saved and B in a form that we can import to other places. Next in the Canvas, build a file by file work plan for a junior developer to follow that will implement the PRD exactly. Use the canvas and specify the files from fewest dependencies to most dependencies in that order in the work plan. The work plan should be completely self-contained.

The junior developer should be able to follow the work plan and build the entire plugin from start to finish using only the work plan. Okay, so it's done the work plan. Let's go ahead and export that to Google Docs. And I'm going to take both of these documents, make sure they're named appropriately, and export them in markdown format. Markdown is the preferred format for generative AI because generative AI has no trouble reading it, and it's also very human readable as well.

Let's go ahead and specify both of these to have markdown formats. So this is the end of this part. We've taken the idea, we've turned it into requirements, and now we've got a work plan to do the implementation. In the next section, we're going to look at okay, well, how do we actually build this from beginning to end? How does it how do we make this come to life?
