name: grok-image-prompt-optimizer description: Optimize text-to-image prompts for Grok and similar image models. Use when the user wants better image generation prompts, poster prompts, competition-grade visual concepts, safer negative prompts, or wants rough ideas rewritten into strong production-ready image prompts. Especially useful for aviation posters, safety campaign visuals, official publicity images, and Chinese-language contest briefs.

Grok Image Prompt Optimizer

Use this skill when the user wants a prompt rewritten so image quality, composition, and thematic accuracy improve.

Goal

Turn vague or overstuffed requests into prompts that are:

visually focused

easy for Grok to parse

poster-friendly

print-friendly

less likely to produce clutter, cheap ad style, or incorrect details

Core workflow

1. Extract the brief into 8 fields: - subject - action - setting - required safety/detail elements - mood/value signal - style - composition - output constraints 2. Reduce the scene to one main visual idea. If the brief contains too many ideas, choose one hero scene and move the rest into supporting details. 3. Rewrite into a structured prompt instead of a rambling paragraph. 4. Add a matching negative prompt. 5. If the use case is a poster, explicitly require: - vertical layout unless told otherwise - strong focal point - clean background - reserved negative space for title/text - print-ready detail 6. If the brief involves regulated or technical domains, prioritize plausibility over spectacle.

Prompt structure

Default structure:

[subject], [action], [setting], [key required elements], [mood / value], [visual style], [composition], [lighting / palette], [output format]

For Grok, prefer 1 clean prompt over multiple conflicting clauses.

Default output format

When optimizing a prompt, output:

1. Main prompt (CN) 2. Main prompt (EN) 3. Negative prompt 4. Quick tweak knobs - more official - more creative - warmer - stronger poster feeling

Grok-specific heuristics

Prefer clear nouns and visible actions over abstract slogans.

Keep 1–3 human subjects unless the user explicitly wants a crowd.

If the image is for a poster, say "poster composition", "clear focal point", "negative space for headline", "vertical A3".

If the image should feel official, use words like:

- professional - trustworthy - orderly - clean - premium - realistic illustration

Avoid asking for too many safety devices in equal visual weight. Choose one primary action and let the rest support it.

If the user says results feel generic, strengthen:

- camera angle - lighting - focal hierarchy - signature scene detail - emotional tone

If the model keeps making commercial-ad images, add:

- public service poster - official campaign visual - not commercial advertising - restrained design

If the model keeps making messy scenes, add:

- minimal clutter - clean cabin background - strong central composition - limited supporting elements

Technical-domain guardrails

For aviation, transport, healthcare, industrial safety, or emergency imagery:

keep actions believable

keep equipment recognizable

avoid sci-fi styling unless requested

avoid disaster-movie panic unless requested

avoid sexualized uniforms or fashion-shoot styling

avoid impossible cabin layouts

Aviation / cabin-safety pattern

When the brief is about cabin safety posters, use this recipe:

Chinese civil aviation cabin safety poster,
[1 main crew subject or 1 small crew group],
[one concrete safety action],
inside a clean modern aircraft cabin,
[1-3 supporting safety elements],
conveying professionalism, responsibility, warmth, and trust,
realistic illustration, premium official campaign poster,
clean blue-white palette with restrained safety-orange accents,
vertical A3 composition, clear focal point, reserved negative space for Chinese headline and copy, print-ready detail

Good primary actions:

demonstrating seat belt use

guiding passengers to stow baggage correctly

pre-departure cabin safety briefing

calm emergency procedure demonstration

assisting compliant passengers during safety preparation

Avoid combining all of these equally in one frame.

Contest-poster rules

If the user is entering a contest, bias toward:

one memorable hero shot

strong symbolic clarity

emotionally legible values

less stock-photo feeling

less corporate ad feeling

more designed poster feeling

Useful style phrases:

competition-grade poster

public service campaign visual

premium realistic illustration

editorial poster design

cinematic but restrained lighting

Negative prompt starter

Adapt as needed:

low resolution, blurry, distorted hands, extra fingers, deformed face, messy composition, cluttered background, incorrect equipment details, incorrect cabin layout, cheap commercial advertising style, overdone sci-fi, anime style, childish cartoon style, garish colors, random text, watermark, logo errors

Tuning patterns

If result is too plain

Add:

dramatic but restrained lighting

stronger visual hierarchy

competition-grade poster design

more iconic hero composition

If result is too busy

Add:

simplified background

only one main action

minimal clutter

fewer secondary subjects

If result is too much like a photo

Add:

premium realistic illustration

poster design quality

editorial composition

If result is too much like an ad

Add:

public service campaign poster

official safety communication visual

restrained, serious, trustworthy tone

Response style

Be decisive. Do not dump theory unless asked.

When the user provides a brief, produce polished prompts immediately.
