AI Image Prompt Engineering

Use When

• Use this skill when the requested outcome is specifically a image prompt engineer deliverable and the supplied brief falls within ai image prompt engineering.

Do Not Use When

• Use caption-writer when its narrower output is the real deliverable; do not use this skill as a generic substitute.
• Do not use it to publish, send, spend, alter a live account, or make unsupported legal, platform, performance, or certification claims.

Required Inputs

Artefact	Source/provider	Required?	If absent
Content brief, channel, audience, message, format and call to action	Requester or approved brief	Yes	Stop and request the missing decision context.
Brand voice, offer facts, constraints and approvals	Client source pack or authorised owner	Conditional	State assumptions; do not invent names, prices, results or approvals.
Performance, platform or research evidence used for claims	Traceable export, URL, document or named source	Conditional	Draft the narrowest reviewable version and flag the missing evidence.

Capability and Permission Boundaries

Drafting is permitted within the supplied brief. Publishing, sending, spending, changing live accounts, or claiming certification requires separate explicit authority. Minimum capabilities are read access to supplied files and search across the authorised evidence set. Use only the files, tools, accounts and evidence made available for the engagement, expose every unassessed check, and obtain explicit authority before any mutation.

Degraded Mode

Fallback: if files, network access, platform data, language review or production tools are unavailable, return the narrowest useful qualified image prompt engineer deliverable; mark unavailable checks not assessed and never convert them into a pass.

Decision Rules

Choice	Action	Failure or risk avoided
Channel, format and audience commitment level are known	Choose the hook, structure and call to action native to that context.	Copy that could be pasted unchanged onto any channel or brand.
A required fact or approval is missing	Stop that claim or action; request it or use an explicit placeholder.	Fabricated facts, implied consent or unauthorised publication.
Evidence is partial but a useful draft is possible	Deliver a qualified draft with gaps and the next verification step.	Treating an unassessed requirement as passed.

Workflow

1. Confirm the exact image prompt engineer deliverable, consumer, market, channel and approval boundary; route to caption-writer if it is the closer match.
2. Inventory supplied facts, source provenance, constraints and missing inputs; stop if the objective, audience or authority is unknowable.
3. Select the domain method and record the material decision behind it before drafting.
4. Produce the smallest complete image prompt engineer deliverable; keep facts traceable and placeholders visibly unresolved.
5. Test the result against the decision table, domain quality criteria and anti-slop gate; recover by narrowing or qualifying unsupported portions.
6. Deliver the artefact with evidence, assumptions, unassessed checks and the next approval or verification step.

Outputs

Artefact	Consumer	Observable acceptance condition
Image prompt engineer deliverable	Requester, client reviewer or delivery team	The image prompt engineer deliverable addresses the named audience and objective, records assumptions, and passes the skill's domain checks without invented facts.
Decision and gap note	Approver or next workflow	Names the chosen route, evidence used, unresolved inputs and any action requiring authority.

Evidence Produced

Evidence	Format	Acceptance condition
Source/assumption register and completed release checklist	Inline table, checklist or linked source note	Every material claim, decision and unavailable check is traceable.

Quality Standards

• Preserve the domain guidance and East African market context below; replace it only when the requester names another market.
• Use British English unless the target language or market requires otherwise, and verify names, figures, quotations and platform rules before use.
• Make the key choice visible, cover failure and edge cases, and keep the result ready for its named consumer.
• Run the repository's anti-ai-slop ship gate; a blocking factual, cultural, safety or permission defect stops release.

Anti-Patterns

• Writing before the objective and audience are known. Fix: stop and obtain the missing brief fields.
• Reusing a neighbouring skill's template because the headings look similar. Fix: route by the requested image prompt engineer deliverable, not vocabulary overlap.
• Adding a price, result, quotation, platform limit or cultural claim without a traceable source. Fix: verify it or qualify/remove it.
• Treating missing access, evidence or native-language review as approval. Fix: mark the check not assessed and narrow the result.
• Publishing, sending, spending or changing a live account from drafting authority alone. Fix: obtain explicit action-specific authority and retain the approval record.

Required Input

Ask for the following before generating any image prompts:

1. Client business name — the exact trading name used publicly
2. Industry — e.g. financial services, hospitality, retail, professional services
3. Country/city — default: Uganda/Kampala
4. Primary goal — what the image is for: social media post, website hero, campaign visual, product showcase
5. Platform — which AI image tool will be used: Midjourney, DALL-E 3, Stable Diffusion, Flux, Adobe Firefly
6. Brand visual anchors — primary colour palette, photographic tone (warm/cool/neutral), and whether the brand is people-centric, product-centric, or environment-centric
7. Subject matter — describe who or what should be in the image, including nationality, age, setting, and any required cultural context

The Golden Rule

AI images carry a distinctive aesthetic: over-smooth skin, slightly off proportions, hyperrealistic fantasy-realist lighting, and symmetrical perfection. The goal is to produce images that look art-directed, stylistically intentional, and culturally accurate — not AI-generated.

This requires precision in prompting, not more prompts. One precisely constructed prompt using all eight layers produces better output than ten vague attempts.

The Eight-Layer Image Prompt Anatomy

Source: LetsEnhance (2024) How to Write AI Image Prompts — From Basic to Pro

Every prompt must address all eight layers. Leaving a layer at its default produces a generic AI aesthetic.

Layer 1 — Subject

The primary focus. Be specific: not "a woman" but "a Ugandan businesswoman in her late 30s, wearing a tailored navy suit, standing confidently at a modern office window."

For East African clients: always specify nationality, city, and context explicitly. AI defaults to Western settings and Western physical appearances. "African" is not sufficient — specify the country, city, and contemporary context.

Layer 2 — Environment

Where the scene is set. Not "office" but "a glass-walled conference room in a Kampala high-rise building, late afternoon, city skyline visible."

For EA clients: specify that clothing is contemporary urban or professional unless traditional dress is specifically required. AI frequently applies culturally inaccurate dress without explicit instruction.

Layer 3 — Lighting

The single most powerful element for photographic realism. Always specify both quality and direction.

Options: natural window light, golden hour, overcast diffused light, dramatic side lighting, studio soft box, practical lamp light. Direction: from the left, from behind, from above, front-lit, rim-lit.

Example: "soft natural light from a large window to the left, creating gentle shadows on the right side."

Layer 4 — Colours

The palette. Specify: warm earthy tones, desaturated pastels, bold primary colours, monochromatic blue-grey, high contrast black and white.

Translate the client's brand palette directly into this layer. For EA clients: skin tone rendering accuracy depends on explicit instruction — specify "true-to-life skin tones for East African subjects" to reduce AI tendency toward over-lightening or over-darkening.

Layer 5 — Mood

The emotional register. Not a feeling but an atmosphere: confident and aspirational, intimate and warm, urgent and dynamic, calm and authoritative, celebratory and energetic.

Mood directs the AI's choices for expression, posture, and colour saturation. State it explicitly.

Layer 6 — Composition

Camera framing. Specify: close-up portrait, wide establishing shot, overhead flat lay, rule-of-thirds framing, Dutch angle, eye-level perspective, over-the-shoulder shot.

For social media: specify the aspect ratio context — portrait (9:16 for Stories/Reels), square (1:1 for grid posts), landscape (16:9 for covers).

Layer 7 — Style

The visual aesthetic. Specify a photography style (editorial fashion photography, documentary street photography, clean product photography), a medium (digital illustration, watercolour, pencil sketch, 3D render), or reference a known visual language without naming a specific photographer to avoid copyright issues.

Example: "the visual aesthetic of high-end African fashion editorial photography" — not "shot in the style of [specific photographer's name]."

Layer 8 — Technical Parameters

Platform-specific specifications:

Platform	Key Parameters
Midjourney	--ar 9:16 (aspect ratio), --v 6 (version), --seed 12345 (reproducibility), --style raw (less AI-filtered output)
DALL-E 3	"photorealistic, ultra-high resolution, DSLR photograph" — describe the full scene in a clear sentence
Stable Diffusion	Negative prompt field essential; ControlNet for pose and composition control; attention weighting for emphasis
Flux	Specify camera type and lens; token-efficient prompts; detail and realism engine
Adobe Firefly	Built-in commercial use rights; include "Adobe Stock style" for clean, licensable outputs

The Negative Prompt Library

Include exclusion language to suppress the AI aesthetic. Apply to all platforms that support a negative prompt field.

Universal negative prompt: blurry, distorted proportions, extra fingers, deformed hands, uncanny valley effect, overly smooth skin, plastic appearance, wax figure aesthetic, AI-generated aesthetic, overexposed highlights, neon oversaturation, fantasy lighting, watermark, signature, text overlay, low resolution, jpeg artifacts

Add for images of people: emotionless expression, doll-like features, exaggerated proportions, inappropriate cultural stereotypes, culturally inaccurate dress, Western default appearance

Apply in platform-specific ways:

• Midjourney: append --no [list] at the end of the prompt
• Stable Diffusion: paste into the dedicated negative prompt field
• DALL-E 3: incorporate as "avoid" instructions in the scene description
• Flux: include as explicit exclusions in the prompt text

Brand Visual Identity Translation Protocol

1. Identify the brand's three visual anchors: primary colour palette, photographic tone (warm/cool/neutral), and subject type (people-centric / product-centric / environment-centric)
2. Translate each anchor into the relevant layer: colours → Layer 4; photographic tone → Layer 7; subject type → Layer 1
3. Use seed numbers (Midjourney --seed) to maintain visual consistency across a campaign
4. Document the seed number and full prompt for every approved image — this is the visual consistency record

Cultural Accuracy in East African Image Prompts

The BuzzFeed Barbie study (2023) documented that AI produced culturally stereotyped and racially inaccurate imagery even with an explicit diversity brief. For East African clients:

• Specify nationality, context, and setting explicitly in Layer 1 and Layer 2 — never rely on "African" as a descriptor
• Specify clothing as contemporary urban/professional unless traditional dress is specifically required
• Specify "East African urban professional" or "Ugandan business context" — not generic "African business"
• Always review images of people with a human reviewer who has direct cultural knowledge before client delivery
• Any image that contains culturally inaccurate representation is rejected and re-prompted, regardless of other quality

Full Prompt Construction Example

Brief: A social media post for a Kampala financial services firm, showing a professional consultation scene.

Constructed prompt (Midjourney):

A Ugandan male financial advisor in his early 40s, wearing a well-fitted charcoal grey suit,
seated across a desk from a Ugandan woman client in her 30s wearing a smart yellow dress,
in a clean modern office in Kampala, glass-walled, city view in the background,
soft natural light from large windows to the left, warm golden tones,
mood: trustworthy and professional, eye-level medium shot, rule of thirds,
editorial corporate photography style, true-to-life East African skin tones,
sharp focus, high detail --ar 4:5 --v 6 --seed 44821 --style raw
--no blurry, plastic skin, fantasy lighting, Western default appearance, text overlay, watermark

Platform-Specific Quick Reference

Platform	Strength	Key syntax
Midjourney	Artistic quality, style range	--ar, --v 6, --seed, --style raw
DALL-E 3	Natural language, accuracy	Full scene description; include "photorealistic" for photos
Stable Diffusion	Control, customisation	Negative prompt field essential; ControlNet for pose control
Flux	Detail and realism	Specify camera type and lens; token-efficient prompts
Adobe Firefly	Commercial licensing	Built-in commercial use rights; "Adobe Stock style" for clean outputs

Quality Criteria

Good output from this skill meets all of the following standards:

• All eight prompt layers are addressed — no layer left at default or unspecified
• Negative prompt included for all platforms that support it, using the universal library plus any people-specific exclusions
• Cultural accuracy review completed by a human reviewer with direct knowledge of the depicted community before client delivery
• Seed number or reference image documented for every approved image, ensuring campaign consistency across multiple assets
• Image reviewed against the brand's three visual anchors (colour palette, photographic tone, subject type) before delivery
• Platform-appropriate aspect ratio and technical parameters specified correctly for the intended use
• Output reviewed against the Golden Rule — any image that looks generically AI-generated is rejected and re-prompted
