Keep Your Old Prompts: Extract the Intent, Then Move Toward Loop Engineering

As AI becomes more capable, the value of prompts lies in allowing it to understand your true goals, quality standards, and red lines. Explicitly writing every step is less valuable.

During a free one-on-one consultation, someone asked me: now, when I just type a prompt, AI sometimes does a good job; but previously, when I wrote detailed skill packages and prompts carefully, the results were not always ideal. What's the difference?

Who is this for
  • You've written long prompts or skill packages, but you start to feel they're holding AI back
  • You want to keep your own work standards, yet hope AI can suggest more suitable approaches
  • You've heard of Loop Engineering, but you still don't know how to connect it with prompts
What you can take away
  • Converting old skill packages into intent reference materials
  • A directly copyable intent-first prompt
  • The minimal process from intent-first to Loop Engineering

Why carefully written prompts sometimes limit AI

Previously, when models weren't mature enough, writing roles, steps, formats, and checking methods clearly could indeed bring results to a usable level. Now that models and tools have advanced, in some tasks, old processes becoming the only rule can prevent AI from using more suitable methods at hand.

Old usageThe process is the only rule

Do every step according to the existing method. The advantage is stability, but the cost is that it is difficult to adjust when encountering new tools or new situations.

Updated usageThe process is your reference for understanding

Keep the standard, tone, and limitations, and let the AI judge the method according to the current task. If you want to change it, first explain the reason and then propose suggestions.

Key difference
Detailed prompts still have value. What needs to change is its role, from an unchangeable instruction, into data that helps the AI understand how you judge a good result.

Old skill packages are actually your foundation

The processes you wrote down in the past often already contain your standards for results, habitual thinking order, imagined scenes, role tone, and what cannot be touched. These are more valuable than a single instruction.

You can hand over your old skill package to the AI, asking it to first distill your goals and preferences, then divide into requirements that must be retained, methods that can be flexible, and steps that may be outdated.

Below are the prompts and skill packages I used to write. Please treat them as reference materials. Distill what my real goal is, the standards for judging quality, the style I care about, and the boundaries I cannot cross. Then, please divide the content into three categories: requirements that must be retained, methods that can be flexible, and steps that may already be outdated. If you have a more suitable approach, please first explain the reason and then propose updated suggestions. When executing, prioritize my intention, with the old process as a reference.

What to write when prioritizing intention

Intention sounds abstract, but actually you just need to let the AI know a few things. You don't have to write long essays every time, but at least let it see the destination and the boundaries.

01Goals and standards

What you hope the reader, client, or team will finally know, what kind of result is considered credible, useful, and like you.

02Scenes and red lines

What role, tone, and context you want to retain, what data cannot be guessed, and what format must be kept.

03Flexibility of methods

Which steps can be adjusted, and if the AI has a more suitable method, how to first explain and report to you.

A directly copyable minimal version

I want to complete [Task] The real goal I want to achieve this time is [Goal] I will use these standards to judge whether the outcome is good [Quality Standards] I want to preserve the style, role, or scene [Style and Context] These are the restrictions I cannot cross [Red Lines] Below are some related workflows or skill packages I have written before Please treat them as references, and extract my intentions and preferences from them [Paste Materials] Please first tell me what you understand about the goal The suggestions for what to keep and update As well as the methods you are prepared to take If there are more suitable approaches, you can propose and explain the reasons Confirm and then start execution

From intention-first to Loop Engineering

For one-time tasks, first clarify the intention, quality standards, and red lines, which is usually very helpful. When encountering tasks that are repeated, have many steps, and require checking results, expand it into Loop Engineering.

Goal and Intention → Execution → Check According to Standards → Correction or Change Method → Meet Delivery Conditions

Loop Engineering is not just asking AI to run multiple times. It will first clarify the goal, standards, starting point, checkpoints, correction methods, and stopping conditions. Intention-first answers why it is done and to what extent; Loop Engineering then adds how to check in the middle, what to do if it does not meet the standards, and when it can end.

The order is very important
Without intention-first, Loop can easily become running endlessly without knowing where to fix. First clarify the judgment standards, so that you know where to place the checkpoints.

First pick the most commonly used old skill package to try

You do not need to rewrite all the prompt words immediately. First find the most commonly used and most seriously written skill package, and ask AI to help you extract the true intention behind it. Those seemingly old workflows often contain your most irreplaceable judgment force.

Use AI as a tool to help you accumulate judgment

The questions in this article come from a free one-on-one consultation. I hold two free online lectures every month, with topics rotating around how to turn workflows, judgments, and experience into AI-friendly prompts, skill packages, and knowledge bases. If you want to receive course notifications or want to discuss stuck prompts, you are welcome to start from the community.

The free lecture sessions will be announced here first, and you can also directly upload your old skill package to see how to extract it together.
