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

html-effectiveness-slides 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 6d 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.

06-slides — 键盘控制幻灯片

"A handful of <section> tags and twenty lines of JS is a slide deck. Point the agent at a Slack thread or a design doc and get something you can arrow-key through in a meeting — no Keynote, no export step."

何时用

用户说 该走这里吗
"做几张 slides 给团队讲讲"
"把这份 RFC 讲一下,slide 形式"
"上台分享 5 页内容"
"做一份幻灯片用键盘翻"
"做一份正式 deck 给 board / 投资人" ✗ 走专业工具 (Keynote),HTML deck 太朴素
"做一份 PDF" ✗ 不是这个 skill 的范畴

标准结构(6 张以内最好)

# 类型 干什么
1 Title 一句标题 + 一句副标题(讲什么、要做什么决定)
2 "Three things shipped" 3 列等宽卡片,并行展示
3 In progress 工作流 + 完成度百分比
4 Metrics 大数字 + delta(2-4 个)
5 Decision needed 决定的问题 + 两个 options
6 Next & closer 下周计划 + "Questions →"

3-7 张是甜区。≤ 2 张走 markdown,≥ 8 张观众睡着。


键盘交互(必备)

行为
Space PageDown 下一张
PageUp 上一张
. Home 回到第一张
f 全屏切换

底部右下角显示 n / total 页码,左下角显示 keyboard hint。


关键 JS(直接复用)

const slides = document.querySelectorAll('.slide');
const pager = document.querySelector('.pager');
let i = 0;

function show(n) {
  i = Math.max(0, Math.min(slides.length - 1, n));
  slides.forEach((s, k) => s.classList.toggle('active', k === i));
  pager.textContent = (i + 1) + ' / ' + slides.length;
}

window.addEventListener('keydown', e => {
  if (e.key === 'ArrowRight' || e.key === ' ' || e.key === 'PageDown') {
    e.preventDefault(); show(i + 1);
  }
  if (e.key === 'ArrowLeft' || e.key === 'PageUp') {
    e.preventDefault(); show(i - 1);
  }
  if (e.key === '.' || e.key === 'Home') show(0);
  if (e.key === 'f') {
    if (!document.fullscreenElement) document.documentElement.requestFullscreen();
    else document.exitFullscreen();
  }
});
show(0);

关键 CSS

.deck { width: 100vw; height: 100vh; overflow: hidden; }
.slide { display: none; min-height: 100vh; padding: 80px 100px;
         flex-direction: column; gap: 24px; }
.slide.active { display: flex; }

.slide h1 { font-size: 56px; font-weight: 500; line-height: 1.1;
            letter-spacing: -0.015em; max-width: 14ch; }
.slide h2 { font-size: 36px; font-weight: 500; line-height: 1.2; }
.slide p  { font-size: 22px; line-height: 1.55; color: var(--gray-700);
            max-width: 60ch; }

.pager { position: fixed; bottom: 24px; right: 32px;
         color: var(--gray-500); font-family: var(--font-mono);
         font-size: 14px; user-select: none; }
.help { position: fixed; bottom: 24px; left: 32px;
        color: var(--gray-500); font-size: 13px; }

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.
