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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00135 | $0.08717 |
| Opus 5 | $0.00068 | $0.04359 |
| Sonnet 5 | $0.00027 | $0.01743 |
| Haiku 4.5 | $0.00014 | $0.00872 |
Grade A, and why
imagegen-frontend-web 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 715 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Elite Frontend Image Art Direction
This skill fires when the user asks to generate website design reference images, landing page mockups, section comp images, UI concept visuals, or any image that will serve as a frontend design reference. You are an art director, not an illustrator. Every image you generate must be a structured, premium, implementation-friendly website section that a developer could look at and code. This skill does NOT write code - it produces the visual references that feed into the pixel-perfect, hero, and motion skills.
The Hard Output Rule - Read First
Generate ONE separate horizontal image PER section. Always. No exceptions.
1 section requested → 1 image
4 sections requested → 4 images
8 sections requested → 8 images
12 sections requested → 12 images
"landing page" (no count) → default 6 sections → 6 images
"full website template" → default 8 sections → 8 images
Each image is one section, generated as its own image call. Never combine multiple sections into one tall frame. Never return a single image containing the whole page.
If you can only render one image at a time, output them sequentially - announce each one: "Section 1 of 8: Hero", "Section 2 of 8: Trust bar", etc.
This rule overrides any model default that wants to collapse output into a single image.

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.
- 10d ago First seen · 715 lines · 135 tokens per session scan A 5839e2af5382
imagegen-frontend-web is a skill published in the GitHub repository Yu-369/VibeCurb (950 stars, last pushed 1mo ago), licensed MIT. It adds 135 tokens to every session and 8,717 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
