Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00099 | $0.01685 |
| Opus 5 | $0.00049 | $0.00843 |
| Sonnet 5 | $0.00020 | $0.00337 |
| Haiku 4.5 | $0.00010 | $0.00169 |
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 yesterday.
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.
This is a copy
95% identical to banner-design — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Banner Design - Multi-Format Creative Banner System
Design banners across social, ads, web, and print formats. Generate multiple art direction options with CSS-built, user-supplied, or optionally generated visual elements. This skill handles banner design only. It 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
Available Resources
This workflow is self-contained: it requires no sibling skills or skill-relative scripts. Use references/banner-sizes-and-styles.md for the bundled size, safe-zone, and art-direction guidance. Browser research, image generation, and screenshot tooling are optional capabilities; when unavailable, use supplied assets, CSS-built visuals, and the runtime's standard preview or capture workflow.
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, logo files, colors, or typography?
- Style preference — any art direction? (show style options if unsure)
- Quantity — how many options to generate? (default: 3)
Step 2: Research & Art Direction
- Read
references/banner-sizes-and-styles.mdfor the target format, safe zone, and suitable styles. - If browser research is available and permitted, collect 3–5 references for composition and art-direction inspiration. Otherwise, work from the bundled reference and any examples supplied by the user.
- Select 2–3 complementary art directions and state how each supports the banner's purpose.
Step 3: Design & Generate Options
For each art direction option:
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
