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 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 →
- high Rogue Agent · line 125 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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 | $0.00030 | $0.02251 |
| Opus 5.5 | $0.00012 | $0.00900 |
| Sonnet 5.5 | $0.00006 | $0.00450 |
| Haiku 4.5 | $0.00003 | $0.00225 |
Grade A, and why
static-page-stack 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 1mo 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Static Page Stack (SOTA, 2026)
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
When to use this skill
The user wants to produce static HTML pages that combine three aesthetic DNAs:
- Magazine / data-journalism (The Pudding, NYT Upshot)
- Technical documentation (Material/Docusaurus/Starlight)
- Computational notebook (Quarto/Observable/Jupyter Book)
…and embed three kinds of SVG:
- Programmatic charts (Vega-Lite / Observable Plot / D3)
- Hand-authored inline SVG (illustrative)
- Whiteboard-style (Excalidraw / tldraw)
Triggers include: "create a static page", "build a dashboard", "design a post-mortem", "set up a technical-doc site", "what HTML/CSS stack should I use", "this Tailwind soup is unmaintainable".
The recommended stack (TL;DR)
| Layer | Pick | Backup | Why |
|---|---|---|---|
| Authoring | Quarto | Quartz, Jupyter Book 2 / MyST | Multi-page, native code+prose+math+execution, MIT, used by Bundesbank/BIS/USGS |
| Visual system | Open Props + native modern CSS | Pico.css | Replaces Tailwind utility soup with semantic tokens (4 KB Brotli); OKLCH + container queries + light-dark() are production-ready in 2026 |
| Typography | Inter + Crimson Pro + Fira Code | IBM Plex family | All FOSS; pairing tested at NYT/Pudding-grade |
| Programmatic charts | Observable Plot | Vega-Lite, ECharts | Cleaner defaults than Vega-Lite, ~95% of needs without going to D3, ISC, Bostock-led |
| Whiteboard | Excalidraw + excalidraw_export CLI |
tldraw (note: $6k/yr commercial license) | MIT, mature, build-time SVG render works |
| Hand-drawn programmatic | rough.js (sparingly) | roughViz, chart.xkcd | Only for "this is exploratory / uncertainty implied" framing |
| Hand-authored inline SVG | CSS-vars-in-SVG pattern | <symbol><use> for shared icons |
var(--token) propagates through inline SVG, giving single design-token surface |
| Scrollytelling | Closeread (Quarto-native) | Scrollama | Closeread is purpose-built for Quarto; Scrollama (~7 KB) for non-Quarto |
What ships with it
2 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.

static-page-stack is a skill published in the GitHub repository terrylica/cc-skills (1 stars, last pushed today), licensed MIT. It adds 30 tokens to every session and 2,251 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-05.
