What is ckm:banner-design?

A system for creating banners in sizes suited to social-media covers, advertisements, website hero sections, and print materials.

Use it to plan and create banners, headers, covers, display ads, website hero visuals, and event or print graphics.

It helps turn one campaign idea into artwork that fits different platforms and purposes while accounting for text, branding, and dimensions.

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	$0.00121	$0.02152
Opus 5	$0.00060	$0.01076
Sonnet 5	$0.00024	$0.00430
Haiku 4.5	$0.00012	$0.00215

Security

Grade A, and why

ckm: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 12d 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.

The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design banners across social, ads, web, and print formats. Generates multiple art direction options per request with AI-powered visual elements. This skill handles banner design only. Does NOT handle video editing, full website design, or print production.

When to Activate

User requests banner, cover, or header design
Social media cover/header creation
Ad banner or display ad design
Website hero section visual design
Event/print banner design
Creative asset generation for campaigns

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
Generate visual elements with ai-artist + ai-multimodal skills

a) Search prompt inspiration (6000+ examples in ai-artist):
```
python3 .claude/skills/ai-artist/scripts/search.py "<banner style keywords>"
```

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
