Building Prompt Templates You Can Reuse

Most people arrive at templates by accident. You write a prompt that works, you paste it again for the next image, you change three words, and after a week you are editing a paragraph you no longer fully understand. A template built on purpose is a different object: a short skeleton with named slots, where every fixed part is fixed because you tested that it earns its place.

Separate the Constants From the Variables

Start from two or three prompts that produced results you were happy with and look for what they share. Usually the shared part is everything except the subject: the medium, the framing, the light, the aspect handling, the general treatment of background. That shared part is the constant half of your template. Whatever changed between the images is a slot.

Write the slots as visible placeholders rather than leaving them implied — subject, action, setting, mood — so that when you fill one in a month later you do not silently drop it. Dropped slots are the single most common cause of a template that used to work and now produces something flatter. The words are gone, so the model reverts to its defaults, and defaults are the average of everything, which is exactly the look you built the template to escape.

Keep the constant part short. A template carrying forty words of fixed styling is not a template, it is a habit, and it will quietly override whatever you put into the slots. If the subject slot cannot compete with the styling, the styling is too heavy.

Test the Skeleton Against Awkward Subjects

A template that only works on the subject it was derived from is a coincidence. Before you trust one, run it with three or four deliberately different fillings — a person, an object, an interior, something abstract. The failures are informative. If your architectural template collapses on a portrait because it specifies a wide lens and a low horizon, you have learned that those two clauses belong to the subject, not to the style, and they should be moved into a slot or split into two templates.

Two narrow templates almost always beat one general one. A general template survives by being vague, and vagueness is what you were trying to remove.

Repairing a Template That Drifts

Templates go stale in ordinary ways. You add a clause to fix one image and never remove it, then it distorts the next twenty. Something you copied in early turns out to have been doing nothing at all, and you keep it out of superstition.

The repair is subtraction. Take the template, remove one clause, generate the same subject, and compare. If nothing moved, that clause was decoration and should stay out. Working through a template this way takes half an hour and usually cuts it by a third, and what remains is a skeleton where you can name the job of every phrase. That is the only version worth keeping, because it is the only version you can debug when an image comes back wrong.
