Token cost

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.

Security

Grade A, and why

oneshot-website 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 12d 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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Oneshot Website

Generate a stunning, self-contained single-file HTML website -- fully immersive, scroll-driven, cinematic. No external images, no build step. Drop into CodePen or push to Vercel as-is.

Inspired by high-end digital brand experiences and the kind of creative coding that makes people say "this was done in one shot?"

When to invoke

Use when:

  • Demonstrating an LLM's creative + technical range for writeups or articles
  • Creating a stunning demo to embed in a CodePen
  • Producing a portfolio piece or proof-of-concept landing page
  • Showing off one-shot generation capabilities

The Generation Prompt

When this skill is invoked, generate the full HTML file using this master approach:


Write complete HTML, CSS, and JavaScript in a single self-contained file for an immersive, cinematic website about [THEME].

The site must feel like a living brand experience -- sections that breathe as you scroll, typography that has weight and presence, and atmosphere you can almost feel.

Theme Selection

If no theme is specified, choose one from the repertoire in references/themes.md that hasn't been recently used. Never default to clockwork, clocks, or time-perception themes.

Recommended defaults (rotate through these):

  1. Elegant restaurant storefront -- dark marble, candlelight, menu sections appearing like courses being served
  2. Luxury perfume house -- mist particles, scent notes drifting, amber and obsidian palette
  3. Antiquarian bookshop at night -- warm amber light, floating text fragments, vellum textures in CSS
  4. Deep sea research station -- bioluminescent creatures via canvas, pressure gauge UI, midnight blue
  5. Jazz club and vinyl lounge -- smoke rings via SVG, waveform visualizations, sepia and amber

Technical Constraints (NON-NEGOTIABLE)

  • Single file: All HTML, CSS, JS in one .html file
  • No external images: Use CSS gradients, SVG inline art, Canvas API, or unicode/emoji symbols only
  • No CDN dependencies for core visuals (Google Fonts via @import is acceptable)
  • No frameworks: Vanilla JS only. No React, Vue, Alpine, etc.
  • Static: Must work as a static file (no server-side logic)
  • Self-hostable: Drop into Vercel as index.html or paste into CodePen

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.

Changes

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.
