What its author says it does
Copied from the file, not written here
Produces branded visual identity elements — logo concepts, icon sets, seamless patterns, brand illustrations, and textures — as generation-ready prompt specs, and generates them via FAL.ai fal-ai/nano-banana-pro when the automation is configured. Use when the user says 'design a logo', 'I need icons', 'brand pattern / texture', 'brand illustrations', 'visual identity elements', or 'make my brand assets'. Produces one prompt-spec block per asset (asset type, style, palette with hex, composition, negative constraints), a variant plan for user selection, file-naming conventions, and a brand-guidelines entry for each approved asset; runs docs/creative_cli.py brand when FAL_API_KEY is set.

Brand Asset
Generate the visual identity elements a brand reuses everywhere — logo concepts, icons, patterns, illustrations, textures — as prompt specs sharp enough that the whole family looks designed by one hand. Prime rule: cohesion over cleverness. A brand asset is judged by how well it matches its siblings and survives resizing, not by how impressive it is alone. And be honest about the medium: the model outputs raster concepts; production logos and icons still need vector tracing.
When to use / when not to
Use for logos, icon sets, patterns, brand illustrations, and textures. Hand off instead when:
- No visual direction exists →
skills/creative/creative-strategistfirst; its brief supplies this skill's style, palette, and mood. For a single throwaway asset, derive a minimal style inline and label it an assumption. - The asset is a product image →
skills/creative/product-photography - The asset is a platform post/banner →
skills/creative/social-graphics - It's a general non-branded image →
skills/creative/image-generation - The user wants a full identity system rolled out across asset types →
skills/creative/orchestratorsequences it (strategist → this skill → the rest)
Intake
Ask in one batch, only what's missing:
- Brand — name, what it does, one sentence of personality.
- Asset type(s) — logo, icon set, pattern, illustration, texture? (These are
also the automation's exact
--asset-typechoices.) - Style anchor — Creative Direction Brief / existing logo to match, or palette hex codes? For icons/patterns joining an existing identity, matching it is mandatory, not optional.
- Usage — where will it live (app icon, website, print, merch)? This drives simplicity requirements and variant needs.
- Automation —
FAL_API_KEYset, or deliver specs only?
Infer, don't ask: aspect ratio (logos/icons/patterns → 1:1; wordmark
lockups → 3:2 or 16:9); resolution 2K (patterns/textures 4K). Don't
stall: with brand + asset type known, assume the rest, label it, proceed.
Workflow
-
Lock the style line. One style from the vocabulary (minimalist, geometric, organic, illustrative, abstract) + palette in words and hex + mood — taken from the Creative Direction Brief when it exists. Every asset in the family uses the same style line verbatim.
-
Write prompt specs from the templates in
references/asset-library.md— read it now; it has the per-type templates, style vocabulary, color application patterns, and delivery specs. Decision rules:- Logo → always generate as concepts to choose from: 4 variants
(
--num-images 4) or 3–4 distinct specs (different style angles). Never one take. Flat, plain background, no photorealism, no tiny text. - Icon set → generate the whole set as ONE sheet in one call so stroke weight and corner radius stay consistent; never one icon per call.
- Pattern/texture → demand
seamless, tileable, edge-to-edgeand test-tile the result before accepting. - Illustration → fix subject + line weight + palette; generate 2–3.
- Logo → always generate as concepts to choose from: 4 variants
(
-
Set negative constraints on every spec: no watermark, no gradients-and- bevels clutter (unless the style calls for it), no readable text beyond the exact brand name supplied, no stock-clipart clichés.
-
Generate or deliver. If
FAL_API_KEY(orFAL_KEY) is set:python docs/creative_cli.py brand \ --asset-type logo --brand-name "TechCorp" \ --prompt "<full prompt>" \ --aspect-ratio 1:1 --resolution 2K --num-images 4Saves to
assets/brand-assets/<brand-slug>/<asset-type>/as<type>_<n>_<timestamp>.png. No key → deliver specs + exact commands; never claim generation happened. Parameter source of truth:skills/creative/image-generation/references/automation.md. -
User selects; you verify. Present variants, have the user pick one per slot (recommend one, one-line reason). Check winners against the quality bar; fix misses with the fix-it phrases in
references/asset-library.md— one iteration round. -
Record in the brand guide. Add each approved asset to the guidelines entry (format below) and state the production step honestly (e.g. "trace to SVG before shipping").
Required output format
One block per asset:
## Asset Spec — [asset name, e.g. logo-concept-A]
- **Asset type:** logo / icon / pattern / illustration / texture
- **Brand:** [name] · **Usage:** [where it will live]
- **Style:** [one style line, shared across the family]
- **Palette:** [color name #hex, role] ...
- **Composition:** [e.g. centered mark, plain background / 6-icon sheet on grid / edge-to-edge tile]
- **Mood:** [2–3 adjectives]
- **Aspect ratio:** [ratio] · **Resolution:** [1K/2K/4K] · **Format:** png
- **Negative constraints:** [no watermark, no text beyond "<brand>", ...]
- **Prompt (final, paste-ready):**
> [single flowing prompt]
- **Variants:** [n] — [what varies]
- **File naming:** assets/brand-assets/<brand-slug>/<asset-type>/<type>_<n>_<timestamp>.png
- **Generate with:** `python docs/creative_cli.py brand --asset-type ... --brand-name "..." --prompt "..." --aspect-ratio ... --num-images n`
- **Production note:** [raster concept — trace to SVG / normalize grid / verify tiling]
After selection, append per approved asset a Brand guide entry: asset name,
file path, color variants needed, minimum size / clear space (logos), and usage
rule — using the guidelines skeleton in references/asset-library.md.
Quality bar
- Every asset in the family shares the same style line and palette verbatim
- Logos: 3+ distinct concepts offered; works in one color; still reads at thumbnail size (describe the check, don't assume)
- Icon sets: generated as one sheet; consistent stroke weight and corner radius
- Patterns/textures:
seamless, tileablein the prompt AND tiling verified (or flagged unverified) - All colors given in words + hex, pulled from the brief when one exists
- Negative constraints on every spec; no text rendered beyond the supplied brand name
- Deliverable states the raster→vector production step for logos/icons — never imply the PNG is print-ready vector
- Only real automation parameters (
fal-ai/nano-banana-pro; no size/steps/guidance knobs exist)
Hard don'ts: never mix two styles in one asset family; never present a generated logo as trademark-cleared (recommend a clearance search); never fake generation results when the API key is absent.
