AI Reads Your Prompt, and It's Not Very Patient

Let me start with something I only figured out recently. AI does not read your prompt with the same level of attention from start to finish.

It reads the beginning most carefully, and starts zoning out by the middle and the end. What does that mean? You put in all that effort writing a long background section, something like 'our team has recently been working on...' 'given the market competition...' 'so I want to...', and it may not have really read it carefully. By the time you finally get to the actual point, it has already zoned out.

There's an article from Tencent Cloud that puts it bluntly: AI is an 'impatient reader'. If the first 500 characters don't say what you want it to do, it starts guessing on its own. While you're writing, you think you're providing background; when it's reading, it only thinks: this person has talked for a while, what exactly do they want me to do?

So there's a counterintuitive move: put the thing you want it to do first, and push the background to later.

Don't write 'because A, so B, please do C'. Write 'please do C. The background is A, and the reason is B.' Tell it what to do first, and then when it reads the supporting material with that task in mind, its attention has somewhere to land. This is different from humans. When you explain something to a colleague, you can exchange a couple of pleasantries before getting to the point. AI has no such thing as small talk; whatever you write before the point, it really reads as the main text.

There's another trap that's even sneakier. Those adjectives you write to 'sound professional' are diluting your instructions.

'Please use a grand and majestic style' 'make it profound and lasting' 'in a lively and vivid style.' While you're writing, you think you're making requirements; when AI reads it, it does only one thing: it goes into the corpus and looks for the phrases that most commonly co-occur with those words. And the phrases that most commonly co-occur are often exactly the most mediocre, least interesting ones.

There's a particularly clear comparison. If you write 'please use an epic style to sketch the future landscape of digital civilization, with profound artistic conception', it gives you 'in the galaxy of technology, human civilization is like a brilliant arrow.' If you write 'describe a future scenario: include one specific technological achievement, and an ethical conflict it brings, shown through a family of three's breakfast conversation', it gives you specific dialogue and scene. The former is you giving it an essay prompt; the latter is you assigning it a task.

So how should you actually write?

Tencent's article gives a plain but very useful principle: turn adjectives into task constraints. Don't say 'write more professionally'; say 'include three data-supported points, and follow each conclusion with a source.' Don't say 'tone should be friendly'; say 'use second person, keep each paragraph to no more than three sentences, and include at least one colloquial transition.'

Adjectives describe the feeling you want; task constraints describe the work it should do. Feelings are vague; work is concrete. Having it do concrete work is more reliable than having it guess at vague feelings.

There's another self-check point worth remembering. Look at whether your prompt has conflicting requirements. For example, 'it should be both professional and rigorous, and also relaxed and lively', or 'it should be both detailed and comprehensive, and also concise and clear.' When you write it, you think 'they don't conflict, I want that kind of balance', but what AI reads is two forces pointing in opposite directions. It can only choose one, or give you a mediocre compromise that satisfies neither side.

If you really need balance, tell it the ratio, or which one takes priority. 'Mainly professional, but end each paragraph with a colloquial sentence.' Give it an ordering it can follow, don't give it a pair of contradictions.

Put simply, the biggest pitfall in writing prompts is using essay-writing habits to write instructions. Essays value foreshadowing, rhetoric, and narrative structure. Instructions require the first sentence to tell it what to do, and every sentence after that to help it do that thing more accurately. The more your writing resembles an 'essay', the more likely it is to treat you as a reader rather than an operator.

Next time before writing a prompt, delete the first two sentences of your draft and start directly with 'please do X'. You'll find it listens much better.
