Asset Generation

Trigger

• logo exploration or logo revisions
• better visual assets in design proposals
• proposal-specific imagery
• provider comparison (Recraft, OpenAI, Gemini/Nano Banana)

Core Rules

1. Use all three providers during exploratory rounds unless user opts out:
   • Recraft
   • OpenAI Image (

     gpt-image-1

     )
   • Nano Banana Pro (Gemini image model)
2. Generate assets in proposal context, not as detached global batch.
3. Exploration width must match design uncertainty:
   • Early rounds: high style/color diversity
   • Late rounds: narrow around survivors
4. Logos must pass favicon/app-icon constraints:
   • flat, simple, low-part count
   • legible at 16px/24px
   • works one-color and full-color
5. If provider outputs are noisy/illustrative, use a deterministic geometric SVG fallback.
6. Treat user-provided logo references as quality primitives only, never literal templates.
7. Never produce marks that can be confused with existing company logos.

Reference Archetypes (Quality North Star)

• modular rounded blocks
• orbiting dot constellation
• constrained grid/mosaic tiles
• minimalist key/keyhole symbol
• 3x3 dot matrix
• hex-aperture emblem

Reference Use Policy (Hard)

1. Extract only abstract qualities:
   • simplicity level
   • geometry type
   • corner behavior
   • stroke/fill balance
   • negative-space strategy
2. Do not reuse exact silhouette, arrangement, or recognizable motif from references.
3. Do not preserve source colorways unless the user explicitly asks.
4. Generate at least 4 structural families per batch before narrowing.
5. Reject anything that looks like "same logo with minor tweaks."

Complexity Budget (Hard Limits)

• 8 primary primitives
• 2 stroke widths
• 2 brand colors + 1 neutral
• more than 1 internal detail per major shape

Phase-Aware Breadth

Phase A: Wide Exploration (no clear winner yet)

• 1 Recraft concept
• 1 OpenAI concept
• 1 Nano Banana concept

• 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)

• 2 focused variants (best provider + fallback provider)
• tightly constrained palette and stroke system

Provider Routing

icon

logo

Logo Prompt Contract

• no text

• no mockup

• no shadows

• no gradients

  (unless explicitly testing gradient direction)

• centered symbol

• flat icon

[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

7a..7h

1. Read proposal DNA + palette + typography mood.
2. Generate 3 logos (Recraft/OpenAI/Nano Banana) using that proposal context.
3. Pick best mark for that proposal only.
4. Embed into that proposal HTML and tune surrounding spacing/contrast.
5. Keep alternates for review.

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

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"

  -H "Content-Type: application/json" \
  -d '{"model":"gpt-image-1","prompt":"minimal flat icon logo mark, no text, no gradients, no shadows","size":"1024x1024","background":"transparent"}'
