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 | $0.00060 | $0.14100 |
| Opus 5 | $0.00030 | $0.07050 |
| Sonnet 5 | $0.00012 | $0.02820 |
| Haiku 4.5 | $0.00006 | $0.01410 |
Grade A, and why
web-weather-creator 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 8d 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 — 1,889 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Weather Creator
Master of stylized atmospheric effects using SVG filters and CSS animations. Creates clouds, waves, lightning, rain, fog, aurora borealis, god rays, lens flares, twilight skies, and ocean spray—all with a premium aesthetic that's stylized but never cheap-looking.
Activation Triggers
Activate on: "clouds", "waves", "weather effects", "atmospheric", "lightning", "rain", "fog", "mist", "aurora", "northern lights", "god rays", "crepuscular", "lens flare", "twilight", "sunset gradient", "golden hour", "ocean spray", "beach wash", "foam", "smoke", "parallax sky", "water ripples", "animated background"
NOT for:
- Photorealistic renders (use WebGL/Three.js)
- Static weather icons (use icon libraries)
- Weather data APIs (use backend services)
- 3D volumetric effects (use Babylon.js/Three.js)
Philosophy: Stylized, Not Cheap
The goal is premium stylization—effects that feel intentional and artistic, not like stock footage or placeholder art.
The Three Principles
- Layering Creates Depth - Multiple semi-transparent layers with parallax motion
- Organic Motion - Varied speeds, easing, and subtle randomization
- Restraint - One hero effect, subtle supporting elements
Quality Spectrum
CHEAP ──────────────────────── STYLIZED ──────────────────────── REALISTIC
CSS gradient blob SVG filter + layered opacity WebGL particles
Single div animation 3-5 layers with parallax Fluid simulation
Linear easing Cubic-bezier + varied timing Physics engine
Target Zone: The middle—stylized enough to feel crafted, performant enough for production.
Clouds Floating Through Content (Z-Index Strategy)
The most common question: "How do I make clouds float through my content, not just behind it?"
The Split-Layer Solution
<div class="atmosphere-container">
<!-- BACK clouds (behind content) -->
<div class="clouds clouds--back"></div>
<!-- Content sits in the middle -->
<main class="content">
<div class="card">Your content here</div>
</main>
<!-- FRONT clouds (in front of content, but transparent) -->
<div class="clouds clouds--front"></div>
</div>
What ships with it
3 files 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.
- 8d ago First seen · 1,889 lines · 60 tokens per session scan A 8e8ecf91b511
web-weather-creator is a skill published in the GitHub repository curiositech/some_claude_skills (221 stars, last pushed 6d ago), licensed MIT. It adds 60 tokens to every session and 14,100 once invoked, about $0.0003 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 2026-09-03.
