Asset Generation

Use this skill for logos, icon marks, hero/section imagery, and texture motifs.

Trigger

Run when user asks for:

• logo exploration or logo revisions

• better visual assets in design proposals

• proposal-specific imagery

• provider comparison (Recraft, OpenAI, Gemini/Nano Banana)

Core Rules

• Use all three providers during exploratory rounds unless user opts out:

• Recraft

• OpenAI Image (gpt-image-1 )

• Nano Banana Pro (Gemini image model)

• Generate assets in proposal context, not as detached global batch.

• Exploration width must match design uncertainty:

• Early rounds: high style/color diversity

• Late rounds: narrow around survivors

• Logos must pass favicon/app-icon constraints:

• flat, simple, low-part count

• legible at 16px/24px

• works one-color and full-color

• If provider outputs are noisy/illustrative, use a deterministic geometric SVG fallback.

• Treat user-provided logo references as quality primitives only, never literal templates.

• Never produce marks that can be confused with existing company logos.

Reference Archetypes (Quality North Star)

Target mark families like:

• modular rounded blocks

• orbiting dot constellation

• constrained grid/mosaic tiles

• minimalist key/keyhole symbol

• 3x3 dot matrix

• hex-aperture emblem

Avoid mascot illustrations, scene composition, and decorative line clutter.

Reference Use Policy (Hard)

When user provides inspiration logos:

• Extract only abstract qualities:

• simplicity level

• geometry type

• corner behavior

• stroke/fill balance

• negative-space strategy

• Do not reuse exact silhouette, arrangement, or recognizable motif from references.

• Do not preserve source colorways unless the user explicitly asks.

• Generate at least 4 structural families per batch before narrowing.

• Reject anything that looks like "same logo with minor tweaks."

This is a hard requirement. "Inspired by" means transferable principles, not copied form.

Complexity Budget (Hard Limits)

Reject marks that exceed:

• 8 primary primitives

• 2 stroke widths

• 2 brand colors + 1 neutral

• more than 1 internal detail per major shape

Accept only marks that remain recognizable at 24px without anti-aliasing blur.

Phase-Aware Breadth

Phase A: Wide Exploration (no clear winner yet)

Per proposal, generate at least:

• 1 Recraft concept

• 1 OpenAI concept

• 1 Nano Banana concept

Diversity matrix (required across batch):

• Geometry: rounded / angular / mixed

• Weight: monoline / medium / bold

• Symbol strategy: abstract / mic-derived / node-derived

• Palette families: warm, cool, neutral, high-contrast, muted

Phase B: Convergence (2-3 survivors)

Per proposal, generate:

• 2 focused variants (best provider + fallback provider)

• tightly constrained palette and stroke system

Logo Prompt Contract

Always include:

• no text

• no mockup

• no shadows

• no gradients (unless explicitly testing gradient direction)

• centered symbol

• flat icon

Template: [brand intent], [shape language], minimalist flat icon logo, no text, no mockup, no shadows, no gradients, centered symbol, transparent or plain background

Proposal-Context Workflow

For each proposal 7a..7h :

• Read proposal DNA + palette + typography mood.

• Generate 3 logos (Recraft/OpenAI/Nano Banana) using that proposal context.

• Pick best mark for that proposal only.

• Embed into that proposal HTML and tune surrounding spacing/contrast.

• Keep alternates for review.

Do not force one logo family across all proposals during exploratory rounds.

QA Gates (Reject if fails)

• noisy illustration masquerading as logo

• too many micro-details for favicon scale

• style clashes with proposal typography/system

• same colorway/style duplicated across whole batch

• visible gibberish text baked into background assets

• mascot/character or scene illustration instead of symbol mark

• more than one focal object in a logo frame

• obvious resemblance to known logos or user-provided samples

• structural near-duplicate across proposal logos

Deterministic Fallback

When model outputs fail QA, generate a clean SVG mark from geometric primitives. This is not optional for quality: use it to guarantee a production-safe floor.

Output Layout

Use proposal-scoped paths:

• .design-evolution/gen-N/assets/logos/7a/recraft-1.svg

• .design-evolution/gen-N/assets/logos/7a/openai-1.png

• .design-evolution/gen-N/assets/logos/7a/gemini-1.png

• .design-evolution/gen-N/assets/textures/7a/*.png

Chosen production candidate:

• .design-evolution/gen-N/assets/logos/7a/final.(svg|png)

Minimal Command Patterns

Recraft (symbol mark)

python3 "$ENGINE" --repo "$REPO" recraft icon
"minimal flat icon mark for Vox Cloud, abstract mic+node, no text, no gradients"
--colors "#1E5CFF,#111827" --n 3 --out "$OUT"
