Design Master — 30-design-master-global

A single master skill that handles 8 design categories for ai-business-skills. One door for both personal work (founder, creator) and brand work (logo, campaign, day-to-day marketing). Reads brand identity from the project context, composes prompts in the right brand voice, and routes the request to the right tool: direct generation via gpt-image-2, paste-ready prompts for 5 popular platforms, or dispatch via Open Design infrastructure.

The skill is written in plain professional English so a non-designer client can read it, understand it, and fill it in alongside the AI. Frontmatter field names stay in English (do not translate) to keep AI parsing intact.

When the user provides a reference image or asks for prompts for image/video/storyboard generation, act as a Prompt Director: classify intent, analyze the image into prompt layers, output an English copy-paste prompt, and state which assets are needed for each image.

The 8 design categories

#	Type	Subject	When to use	Tool
1	personal-brand	Individual (founder/creator)	Profile avatar, monogram, speaker cover, personal quote graphic	gpt-image-2 raster
2	business-logo	Brand logo identity	Logo primary/secondary/mark	gpt-image-2 multi-variant 3-5 directions + human-review disclaimer
3	business-campaign	Brand campaign visual	TVC still, OOH, product hero, campaign key visual	gpt-image-2 raster
4	marketing-day-to-day	Operational marketing	Social post, banner ad, email header, story	gpt-image-2 raster
5	editorial	Long-form publication	Magazine cover, article hero, e-book, lookbook	gpt-image-2 raster
6	infographic	Data/plan/process visualization	Roadmap, process flow, comparison chart	gpt-image-2 (text-minimal, icons-focused)
7	web-mockup	UI screen sketch	Landing hero, app screen mockup	Hybrid: gen 1 hero image via gpt-image-2 + recommend HTML skills for the full interactive mockup
8	quote-graphic	Quote post	"Guru post" IG, LinkedIn quote, motivational	Hybrid: gpt-image-2 background + HTML text overlay

Mode detection cascade (Step 0)

Three layers of type detection, in priority order:

Layer 1 — Keyword auto-detect

Keyword	Detected type
"avatar", "profile picture", "monogram", "speaker cover", "headshot"	personal-brand
"logo", "wordmark", "lockup", "brand mark"	business-logo
"key visual", "campaign visual", "TVC still", "OOH", "product hero"	business-campaign
"social post", "banner ad", "email header", "IG story", "Facebook post"	marketing-day-to-day
"magazine cover", "article hero", "e-book cover", "editorial", "lookbook"	editorial
"infographic", "roadmap visual", "process flow", "comparison chart", "data viz"	infographic
"hero web", "landing hero image", "app screen mockup"	web-mockup
"quote", "quote graphic", "guru post", "motivational post"	quote-graphic
"reference image", "same style", "same composition", "master prompt", "based on this image"	keep detected type + activate Prompt Director reference mode
"change color", "brand color", "add logo", "replace logo", "match brand guideline"	keep detected type + activate Prompt Director brand adaptation
"too AI-looking", "not realistic", "wrong color", "wrong angle", "revise prompt"	keep detected type + activate Prompt Director diagnosis

Layer 2 — Explicit flag

The user passes --type=business-logo (or one of the other 7 types) → overrides Layer 1.

Layer 3 — Ambiguous fallback

If nothing matches and no flag is set → ask one single question:

"Which of the 8 design types is this?

1. personal-brand 2) business-logo 3) business-campaign 4) marketing-day-to-day 5) editorial 6) infographic 7) web-mockup 8) quote-graphic"

Print a transparency line before continuing:

[detect type: business-logo — matched keyword "logo" + brand name "Lattéa"]

---

Prompt Director mode

Activate this mode when the user provides reference images, asks for a master prompt, wants face/color/logo replacement, or gives feedback on a failed result. Load references/prompt-director.md before composing the prompt.

Rules:

• Do not start with a long questionnaire. If the request is usable, generate the prompt first and list missing pieces at the end.
• A reference image is a style/composition source, not automatically a face, logo, or product source unless the user says so.
• Ask for replacement assets by type: face reference, logo file, brand palette hex, product image, background/location, exact text.
• Multiple images = multiple flows. Name them Flow A/B/C, state each image role, provide a prompt, a negative prompt, and the missing-asset list for each flow.
• Final prompts for image/video models default to English; user-facing explanation follows the user's language.

Reference-image output skeleton:

## Image flows

| Flow | Input image | Role | Output |
|------|-------------|------|--------|
| A | [file/path] | style/composition reference | master prompt |

## Copy-paste prompt — Flow A
[English prompt]

## Negative prompt / Avoid
[English avoid list]

## Upload next to personalize Flow A
- Face reference:
- Logo:
- Brand colors:
- Exact text:
- Product/background:

Runtime workflow — 5 steps

Step 1 — DETECT design type

Run the 3-layer cascade above. Print [detect type: ...] before moving to Step 2.

Step 2 — LOAD references

Load lazily, as needed:

• CONVENTIONS.md — load once per session
• references/prompt-director.md — load for reference images, master prompts, face/color/logo replacement, multiple images, or prompt feedback
• references/<type>.md — load the file matching the type just detected (e.g. references/business-logo.md)
• references/brand-identity-source.md — load whenever the type starts with business-*
• references/fallback-prompt-format.md — load when the tier is Free (see Step 5)
• templates/<format>.md — load the template matching the requested format (e.g. templates/poster.md, templates/social-square.md)

Step 3 — READ brand identity

Business modes (business-logo / business-campaign / marketing-day-to-day): REQUIRED — must find brand identity. Auto-search in priority order:

1. assets/brand/logo.{svg,png,ai} — primary logo file
2. brand-guideline.md / brand-identity.md at the project root
3. 02-campaign-brief-global/output.md section "Brand mandatories" — campaign brief carries brand constraints
4. prd.md frontmatter target_user + section "Visual cues" — style direction
5. prd.md Section 6 — features that inform the visual concept

If nothing is found for a business mode → BLOCK + ask the user to upload a logo + specify a palette (3 hex codes) + name a primary font family.

Personal modes (personal-brand / personal quote-graphic): brand identity is optional. Enough to have style adjectives (3–5 words) + a color preference (3 mood colors).

Editorial / Infographic / Web-mockup: context-dependent — treat as business mode if the asset is for a brand, treat as personal if it's for an individual or a general-purpose piece.

Step 4 — ROUTE by type

Type	Route action
1–5 (personal-brand, business-logo, business-campaign, marketing-day-to-day, editorial)	COMPOSE raster prompt → go to Step 5
6 (infographic)	COMPOSE prompt with text-minimal strategy: icons-heavy, branded palette, max 2-3 number stats, NO long paragraphs → go to Step 5
7 (web-mockup hybrid)	COMPOSE 1 hero image prompt → Step 5 + print the HTML skill recommendation block, exit gracefully after the hero is generated
8 (quote-graphic)	COMPOSE background image prompt (NO in-image text) + create an HTML overlay template (text rendered via HTML, never burned into the image)

Step 5 — CHECK API tier + GENERATE

Detect the tier in Bash:

if [[ -n "$OPENAI_API_KEY" ]]; then
  TIER="pro"   # direct gpt-image-2
elif [[ -n "$OD_BIN" && -x "$OD_BIN" ]]; then
  TIER="enterprise"   # Open Design dispatcher
else
  TIER="free"   # prompt-only fallback
fi

Print line: [tier: <X>] [model: <Y>].

Tier	Behavior	Output
Free	No API key available	docs/design/<slug>-prompt.md with paste-ready prompts for 5 platforms (DALL-E 3, MidJourney v6, Leonardo, Imagen 3, Bing/Copilot Designer) — see references/fallback-prompt-format.md
Pro	OPENAI_API_KEY is set → call gpt-image-2 directly	docs/design/<slug>.png + docs/design/<slug>.md (metadata)
Enterprise	$OD_BIN exists and is executable → dispatch via Open Design infrastructure (the existing image-poster infra)	docs/design/<slug>.png + docs/design/<slug>.md (metadata with gen_mode: api-dispatcher)

Type 7 web mockup — after generating the hero image (if Pro/Enterprise tier), print a recommendation block:

[NEXT STEP] Hero image generated. For a full multi-section interactive mockup,
also run one of:
  - web-prototype (general landing/marketing page)
  - saas-landing (SaaS product page)
  - mobile-app (mobile app screens)
  - dashboard (admin/analytics dashboard)
  - frontend-design (Figma-style design tokens)

Type 8 quote graphic — output 2 files:

• docs/design/<slug>-bg.png — background image generated via gpt-image-2 (NO text)
• docs/design/<slug>.html — HTML overlay rendering the quote text on top of the background (HTML keeps typography crisp; avoids AI garbling letters)

---

Frontmatter schema for the output file

Every docs/design/<slug>.md metadata file MUST carry this frontmatter:

---
title: <Image asset name>
type_artifact: image-generated | image-prompt-fallback | infographic-html | web-hero-image
mode: personal-brand | business-logo | business-campaign | marketing-day-to-day | editorial | infographic | web-mockup | quote-graphic
subject: <1-line description>
source_brief: <path to source brief if any>
brand_identity:
  logo_path: <path or "none">
  palette: [<hex>, <hex>, ...]
  typography: <font family or "none">
  style_adjectives: [<adj>, <adj>, ...]
format: poster | social-square | social-vertical | banner-hero | magazine | infographic | logo-variant | quote
aspect_ratio: 1:1 | 9:16 | 16:9 | 3:4 | 4:3 | custom
gen_mode: api-direct | api-dispatcher | fallback-prompt | hybrid
model: gpt-image-2 | dall-e-3 | midjourney-v6 | flux | imagen-3 | manual
output_files:
  - <path>
created: 2026-05-20
last_updated: 2026-05-20

Field names stay in ENGLISH — do not translate (would break AI parsing). The body of the file can be in any language the client reads.

Error handling — 8 real-world situations

Situation	How to handle
Type is ambiguous (no keyword match, no flag)	Ask 1 single question with all 8 options (see Layer 3 in Step 0)
Business mode + brand identity missing	BLOCK + ask the user to upload the logo + specify a palette (3 hex codes) + name a font family
OPENAI_API_KEY invalid / quota exceeded when calling gpt-image-2	Fall back to Free tier (prompt-only) + print an error line
Type 7 web mockup but user actually wants a full multi-section UI	Hybrid is fine: generate the hero image + attach a recommendation for web-prototype (or one of the 4 sibling skills) for the full mockup
Logo gen requested but no brand values yet	Probe with 3 questions: brand name, industry, values (3-5 words) — only then is it possible to generate a logo with any soul
Infographic text-heavy, >5 data points	Warn: "Text inside AI-generated images is unreliable. Recommend using a Canva template for text-heavy infographics." Still generate if the user confirms.
Quote graphic text >50 characters	Warn: same — recommend using a generated background only + HTML overlay (which is already the default for type 8)
User asks for a format that doesn't match the detected type	Suggest the matching mode — e.g. "landing page banner" → mode=marketing-day-to-day format=banner-hero

---

Anti-patterns — DO NOT

• Generate a logo as the final deliverable → always produce a multi-variant set (3–5 directions) + human-review disclaimer
• Burn >50 characters of text into an image — AI gen mangles long text, breaks spelling, distorts accented characters
• Pass a raster web mockup off as interactive — must be hybrid + recommend an HTML skill
• Skip the brand identity check on business modes — the output will look disconnected from the brand
• Output a prompt that's just a keyword list (e.g. "nice cafe logo") — must follow the 5-section structured prompt framework: subject + composition + lighting + palette + style + negatives
• Hardcode hex colors when the project already has a brand identity file — read from source
• Translate frontmatter field names to a non-English language — breaks AI parsing
• Generate >1 image per turn, unless it's a logo multi-variant set
• Save only a prompt without generating the image while on Pro/Enterprise tier — wastes the API budget
• Generate an image without saving a .md metadata sidecar — context is lost next time

---

Self-test before generating

Before every gpt-image-2 call or fallback prompt export, ask yourself:

"Does this output align with the brand voice and identity? Would a client recognize the brand when they see it? If this is personal brand work — does it reflect the style adjectives the user actually wrote down?"

If you can't confidently answer 2 out of 3 → go back to Step 3, re-read the brand identity, or probe the user with 1–2 more questions.

Plain English policy

This skill is written in plain professional English so a non-designer business owner can read it, follow along, and fill it in alongside the AI. Technical terms (gpt-image-2, DALL-E 3, MidJourney) are kept verbatim and briefly explained the first time they appear. Examples use realistic global-feeling brands: Lattéa (a fictional global cafe chain), Lumière Studio (creative agency), AI Income Mastery (online course), OPA (product). No throwaway placeholder brand names.

Self-test for plain-English fit: "Would a small business owner who doesn't speak design jargon understand this section?" If not — rewrite it.
