create-html

A skill for turning notes, research, comparisons, plans, or reports into one responsive HTML briefing. The result is a self-contained page that can be opened and shared without a build system or external services.

In plain words
What is it for?
Use it to create visual briefs, dashboards, comparison pages, timelines, or shareable reports from supplied content.
Why use it?
It turns unstructured material into a readable page with a clear information structure and checks it for desktop and phone layouts.

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

create-html 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 2d 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create HTML

Turn the user's content into one complete HTML file that is calm, readable, and ready to share. Keep the information primary; styling should make the structure easier to scan.

Workflow

  1. Confirm the source material, audience, and purpose from the conversation and local files. Do not invent facts to fill empty sections.
  2. Decide the information structure before styling. Prefer a short narrative, comparison table, timeline, or paired question-and-answer layout over a grid of generic cards. Read layout-patterns.md when the page has multiple content types.
  3. Copy brief-template.html as the starting point. Remove unused components and replace every {{PLACEHOLDER}}.
  4. Write a single self-contained .html file. Keep CSS and any small SVG illustrations inline. Do not require a build step, JavaScript framework, CDN, external font, or analytics.
  5. Verify the content and public-safety boundary before presenting or publishing it.
  6. Check the rendered page at desktop width and around 390 px. Fix overflow, awkward wrapping, tiny text, and excessive empty space.

Design contract

  • Use light mode with deep blue as the base, neutral white surfaces, and gold as the only accent.
  • Reserve the blue gradient for the hero, section markers, and table headers. Do not fill every component with gradients.
  • Keep the main content at about 940 px, body text at least 16 px, and line height around 1.8.
  • Use Japanese system fonts first: -apple-system, BlinkMacSystemFont, "Hiragino Sans", "Yu Gothic UI", sans-serif.
  • Give each section one clear message. Use cards only for genuinely independent facts or metrics.
  • Make tables horizontally scrollable inside their own container; never let the page itself scroll sideways.
  • Use semantic headings in order, visible focus styles, sufficient color contrast, and descriptive link text.
  • Keep decorative icons minimal. Prefer CSS shapes or inline SVG to emoji-heavy decoration.

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.

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.
