About the project

html-anything is a local AI-assisted HTML editor in which coding-agent command-line tools create documents such as articles, presentations, posters, prototypes, and reports from reusable templates. People use it to produce HTML and export it to services such as WeChat, X, and Zhihu or to HTML and PNG files. The catalogue entries are the skills and instructions that define its output surfaces and workflows.

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

prototype-web 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 yesterday.

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.

What it actually says

【模板: Web 产品原型】

  • 输出一个完整的产品 landing page。
  • Sections: Top Nav (logo + 导航 + CTA 按钮) → Hero (大标题 + 副标 + 双 CTA + 可视化占位) → Features (3-6 个特性卡) → How it works (步骤) → Social proof (logo wall / 评价) → Pricing (可选) → Footer。
  • 使用现代 SaaS 设计趋势: 大字号、柔和渐变、glassmorphism 卡片、滚动到视图入场动画 (pure CSS 即可)。
  • 响应式: 移动端单栏, 桌面多栏; 至少处理 md: 断点。
  • 添加交互: nav 滚动变色; 特性卡 hover 浮起; FAQ 可手风琴展开 (用 <details>)。
  • 这是高保真原型, 应该让人觉得"明天就能上线"。

What ships with it

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.
