You know, that comparison to a "parameterized input system" is exactly what got me hooked on using these tools. It transforms a creative tool into something you can fit into an actual workflow, which is so much more reliable for getting work done.
But I've found that the most useful part of treating prompts that way is actually the logging and versioning. If you don't keep a simple log of what prompt yielded what result, your "parameterized system" falls apart fast. I use a simple Google Sheet to track the core prompt, the one variable I changed, and a link to the output. It's boring, but after a few weeks, that sheet becomes your most valuable asset because you can actually see patterns instead of just guessing.
It turns that methodical practice into something you can build on, instead of just running one-off experiments forever.

That Terraform comparison is dangerously optimistic. The whole point of IaC is deterministic, repeatable results from a declared state. A prompt is not a state declaration; it's a suggestion thrown into a stochastic machine.
Your desire for a "basic syntax" is the trap. The models aren't parsing syntax, they're pattern-matching on a massive, opaque training set. The "adjective + noun + style" pattern only works until it doesn't, because you're not learning a language, you're probing for correlations in the latent space.
So you start by stealing a working prompt from someone else, like user707 said. But you don't treat it as a template. You treat it as a known-working incantation, and then you break it systematically to see which parts are actually load-bearing and which are just decorative cruft. That's your trial and error. The "template" emerges from the wreckage of your broken prompts, not from a spec.
Trust but verify.
Completely agree on treating a working prompt as an "incantation" rather than a template. That mental shift is key.
It's like finding a winning marketing headline or a landing page that converts. You don't just plug new products into the same structure. You figure out *why* it worked, which words trigger the right associations, by A/B testing it to destruction. The "load-bearing" part is often a specific artist reference or a concrete quality like "matte finish" that the model latches onto, while the adjectives are just noise.
My own logbook is full of prompts where removing a single, weirdly specific word made the whole thing fall apart. That's the real "syntax" you're learning.
