Mind Readings: How to Vibe Code Well, Part 3

Welcome back. This is part three building the work plan. In the first part, we talked about asking good questions, coming up with ideas that we would even want to vibe code. In part two, we talked about the requirements gathering process, and we spent a lot of time on requirements gathering. The next part is to build a work plan.

So I'm going to go back into Google's uh Gemini, which is the system we've been using, and gonna pick up where we left off. Here is our product requirements document. Um, what we want to say next is we want to say build based on our product requirements document, let's create a work plan to build the Chrome extension from the PRD. It must be a highly detailed set of instructions, file by file, for a developer to use to update the code base. The file should be ordered from fewest to most dependencies and must contain the file path, the changes needed, the upstream and downstream dependencies to keep in mind, and the overall intent of the file.

The work plan must be granular enough that the developer needs no other information to make the necessary code from the PRD. Build the work detailed work plan in Markdown using the canvas. The extension name will be called, oop, that's wrong. That's from a leftover. Uh let's make sure edits that mark plan.

The extension will be called data dialist. That is the correct name of our tool. It's now beginning to generate the work plan. One thing I want to emphasize here is that, and I probably should have said this up front. You need to use a reasoning model for these stages for the asking questions, for building the requirements document for building the work plan.

You must use a reasoning model. So this would be Gemini 2.5, Claude 4, OpenAI 03, anything where it shows you a thinking block and it gives itself time to think things through, to think through a solution. The reason for that is that these tools effectively, if you pop open the reasoning block, in a lot of cases, they're kind of doing a rough draft or gathering their thoughts about how to perform the task. And that's really important. Non-reasoning models like GPT 4.0 or 4.1, um, or anything in that family, Deep Seek V3, etc., they can't think things through like that.

And so they are more prone to mistakes, they're more prone to hallucinations, they are more prone to come up with code that's just gonna be non-functional out of the box. And so we can see here the work plan now is being built nicely. Um, and we're now at the testing phase. So here's the the work plan. Um you have a clear path in PRD to functional Chrome extension.

Let's give it a take a look, browse through. Uh, let's see. Yeah, you know, that's that's not bad. Um, I don't know that I love this version of the work plan. I think I need to add a sentence to the prompt that says uh let's have you include code samples because this is good, but it's not great.

Again, going back to uh our what we said earlier about uh plan big, act small. We want to give the small model as little to do as possible, a little thinking to do. We want it to uh just do stuff. If you think of it in terms of management, this is the the project manager, and then the the small model is the doer, the junior coder on the team that's going to be uh writing the stuff by so by adding in something like add diff code samples appropriate for use with systems like Git, we're going to encourage it to try and build um using as much as many samples as possible. You can see in this version now, it's starting to produce the actual code samples themselves, the the diffs for our our Git uh version control software.

Okay, we have a work plan now. So we're gonna go ahead and take this work plan. We're gonna go into our documents, paste it in the work plan section. Just take a quick look at it. This work plan is over 1600 lines long.

That's how much stuff it's gonna do. I'm gonna trim off the uh the header there just so that the work plan is itself all cleaned up. And now we're actually ready to begin the vibe coding process. This is really important. Vive coding, if you want it to work well, can't just be something where you you think casually, oh, just make me an app that does this.

It it still requires thinking, it still requires planning, it still requires asking good questions. Um, it requires all the parts of the SDLC that if you want your code to run, you do up front. If you don't want to burn your budget or blow out your APIs or or cost yourself a gazillion dollars in tokens, you do this hard work up front, this planning up front, so that when the tool goes to work, it can actually make it. So that's the work plan. In part four, we're gonna set off, we're gonna go off to the races.
