AI plan: How to write a plan that works well for AI

When applying an AI plan for the first time, we have organized the structures, screens, and priorities that are often blocked for non-majors. We have organized key standards, common mistakes, inspection points, and next actions in one place so that you can directly attach them to the actual planning and execution flow, so apply them right away.

AI plan is the main topic of this guide. If you are applying AI plan in a real project, start with the structure and checks below.

This article is organized based on points that frequently get stuck when attaching an AI plan to actual work flow.

It is safer to check the current environment and official documents before actual application.
When doing vibe coding, many people start by looking for prompt secrets. But in reality, it’s clear requirements rather than fancy sentences that make the biggest difference to your results. AI is a tool that is good at following what you say, but if the standards are unclear, it can easily leak into a direction that seems plausible. So, the more beginners, the more they need a plan that explains what to make and under what conditions to operate before the prompt.

A good plan is not good just because it is long

A plan may seem grand, but it doesn’t need to be a long document from the beginning. Rather, it is enough to do the five things below first.

  • One line description of service
  • Target User
  • 3 core features
  • Features we won’t do
  • Conditions for completing the first version

With just these five lines, you can give much clearer instructions to the AI. The problem is that many people directly request implementation without this standard. AI will then make it faster, but the scope will continue to widen and modifications will be overturned frequently.

Vague requests shake up the project

For example, there is a direction to “create a household account book app for beginners,” but there is a lack of standards. On the other hand, it is much more stable if you say, “Create a single-person household account book app where you can quickly enter spending items on your mobile phone and see today’s total. Please exclude membership registration and statistics functions from this version.” A good plan is not a document that explains everything to AI, but rather a boundary line that tells AI what to do and what not to do.

It is better to divide it into steps rather than doing it perfectly all at once.

When writing a plan, it is better to break it down into steps rather than putting all the requests in at once. First, the overall structure is explained, then the roles of each screen are divided, and detailed functions are added at the end. This way, AI can better maintain context and make it easier to determine at what stage changes were made, even if changes are made. Vibe Coding is closer to building up small agreements rather than one large order.

What is the difference between good proposal sentences?

A good proposal sentence is clear rather than pretty. For example, “a structure that allows you to check results in two steps on mobile” is much more specific than the expression “user-friendly service.” “Top description, middle input window, bottom result list” is more useful than “simple design.” AI responds better to concrete conditions than to abstract exclamations. Therefore, it is better to write sentences in the proposal that are less likely to be misunderstood than to be flashy.

The plan is not just a document for AI, it is a standard for me

The real advantage of the plan does not end with making AI work well. What’s more important is that it helps me not lose direction when I look at it again later. When another feature comes to mind a few days later, it becomes a standard for judging whether it is necessary now or something to postpone until later. In the end, a good plan is not a professional document for developers, but rather a safety device for non-majors to carry out the project without hesitation.

If you have an idea you’re working on today, don’t complicate it, just write down five lines first. There will definitely be moments when those five lines will have more power than the prompt. In the next article, we will look at how this plan can be translated into actual data structure thinking.

As an easy example,

For example, if you ask AI, “Create a household account book app for beginners,” the results are likely to spread widely. Conversely, if you write, “A single-user app that quickly inputs expenses on mobile and shows today’s totals, but excludes logins and statistics,” the AI ​​will also have a much clearer understanding of what to do.


Quick checklist for AI plan

Use this checklist before you apply AI plan in an actual post or product flow.

  • Is the first action obvious as soon as the user lands on the page?
  • Are intermediate steps simple enough that buttons and explanations do not overlap?
  • Does the result naturally lead to a next action instead of a dead end?
  • Could you explain the structure again later without adding unnecessary screens?

Things to verify before you apply it

  • Tool UI and function configuration may vary depending on the time, so it is safer to check again based on the current version.
  • Stateful features like external APIs, authentication, and payments can have a much larger structural impact in a real project than in a small example.
