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: 4 findings, up to medium
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 | $0.00093 | $0.04255 |
| Opus 5 | $0.00046 | $0.02128 |
| Sonnet 5 | $0.00019 | $0.00851 |
| Haiku 4.5 | $0.00009 | $0.00426 |
Grade A, and why
data-viz-2025 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 11d 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.

Data Visualization 2025: The Art & Science of Visual Communication
Create visualizations that Seaborn users, Tufte readers, and everyone else will love. Marry NYT Graphics rigor with MoMA aesthetics, Nike energy, and On Kawara precision.
When to Use This Skill
✅ Use for:
- Building interactive charts, dashboards, and data stories
- Complex visualizations (chord diagrams, Sankey flows, network graphs)
- Real-time data displays with animations
- Mobile-responsive data components
- Accessible, tested visualizations for production
❌ NOT for:
- Static PNG/SVG exports without interaction (use design tools)
- Basic HTML tables (use semantic markup)
- Print-only graphics (different constraints)
- Simple icon displays (use icon libraries)
Core Philosophy: The Three Pillars
1. Clarity (Tufte's Data-Ink Ratio)
Every visual element must earn its place. Remove chart junk, maximize signal-to-noise.
2. Beauty (Aesthetic Standards)
Visualizations are art. Use spring physics, thoughtful color, and premium design systems.
3. Truth (Graphical Integrity)
Data representation must be honest. Test rigorously, document assumptions, preserve context.
Quick Decision Tree
What are you building?
├─ Exploratory analysis / many iterations
│ └─ → Observable Plot (grammar-of-graphics)
│
├─ Standard business charts (bars, lines, pies)
│ ├─ Simple React integration needed
│ │ └─ → Recharts (easiest, most popular)
│ └─ Premium aesthetics + theming
│ └─ → Nivo (beautiful out of the box)
│
├─ Custom, one-of-a-kind visualizations
│ ├─ Need low-level control
│ │ └─ → Visx (React + D3 primitives)
│ └─ Full D3 power
│ └─ → D3.js directly (steeper learning curve)
│
└─ Dashboard with Tailwind design system
├─ → Tremor (purpose-built for dashboards)
└─ → shadcn-ui Charts (Recharts + shadcn styling)

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.

data-viz-2025 is a skill published in the GitHub repository curiositech/some_claude_skills (219 stars, last pushed 5d ago), licensed MIT. It adds 93 tokens to every session and 4,255 once invoked, about $0.0005 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.
