What is banner-design?

A design guide for creating banners in different sizes and visual styles. It covers social-media covers, advertisements, website hero images, and print banners.

Planning and producing banner concepts with headlines, supporting text, calls to action, logos, brand rules, platform dimensions, and safe areas.

It helps avoid layouts that crop badly, hide important text, or fail to fit the chosen platform and brand requirements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.02159
Opus 5.5	$0.00023	$0.00864
Sonnet 5.5	$0.00012	$0.00432
Haiku 4.5	$0.00006	$0.00216

Security

Grade A, and why

banner-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Creative asset generation for campaigns

Prerequisites

Python: This skill uses Python scripts. On Windows, use python instead of python3 (e.g., python scripts/search.py instead of python3 scripts/search.py).

Workflow

Step 1: Gather Requirements (AskUserQuestion)

Collect via AskUserQuestion:

Purpose — social cover, ad banner, website hero, print, or creative asset?
Platform/size — which platform or custom dimensions?
Content — headline, subtext, CTA, logo placement?
Brand — existing brand guidelines? (check docs/brand-guidelines.md)
Style preference — any art direction? (show style options if unsure)
Quantity — how many options to generate? (default: 3)

Step 2: Research & Art Direction

Activate ui-ux-pro-max skill for design intelligence

Use Chrome browser to research Pinterest for design references:

Navigate to pinterest.com → search "[purpose] banner design [style]"
Screenshot 3-5 reference pins for art direction inspiration

Select 2-3 complementary art direction styles from references: references/banner-sizes-and-styles.md

Step 3: Design & Generate Options

For each art direction option:

Create HTML/CSS banner using frontend-design skill
- Use exact platform dimensions from size reference
- Apply safe zone rules (critical content in central 70-80%)
- Max 2 typefaces, single CTA, 4.5:1 contrast ratio
- Inject brand context via inject-brand-context.cjs
