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.

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 | $0.00256 | $0.02954 |
| Opus 5.5 | $0.00102 | $0.01182 |
| Sonnet 5.5 | $0.00051 | $0.00591 |
| Haiku 4.5 | $0.00026 | $0.00295 |
Grade A, and why
html-slide-builder 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 — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.

0. 讀取教材
接受任何形式的輸入：
- 文字 / Markdown：直接分析
- PDF：用 Read 工具讀取（若有多頁先讀摘要頁）
- 口述主題：自行根據標準教學邏輯設計（引言→概念→範例→互動→結論）
若教材資訊不足，不要詢問，直接用教學慣例補充。
1. 分析大綱，等使用者確認
分析完畢後輸出大綱表格，等使用者確認後才繼續：
## 📋 簡報大綱草稿（共 N 頁）
| 頁碼 | 標題 | 內容摘要 | 功能標記 |
|------|------|----------|----------|
| 1 | 封面 | 課程名稱、講師 | [BG] |
| 2 | 破冰提問 | 文字雲收集學員想法 | [INTERACT:wordcloud] |
| 3 | 三大重點 | 並列說明三個核心概念 | [ICON] |
| 4 | 前後對比 | A 方案 vs B 方案演進 | [VIZ] |
...
**功能標記說明**
- [BG] 背景底圖（draw 技能，暗色風格）
- [ICON] 扁平化圖標（draw + PIL 去背）
- [INTERACT:wordcloud] Firebase 即時文字雲
- [INTERACT:poll] Firebase 單選投票
- [VIZ] 滑桿視覺化演示（clip-path）
請確認大綱，或說明要調整的地方。
功能標記的決策原則
| 標記 | 觸發條件 | 每份簡報目標數量 |
|---|---|---|
| [BG] | 封面、封底、章節轉換、高衝擊結論 | 3–5 頁 |
| [ICON] | 頁面有 3–6 個並列項目（優缺點、步驟、特性） | 1–3 頁 |
| [INTERACT:wordcloud] | 開場破冰、先備知識調查、課尾反思 | 1 頁（通常第 2 頁） |
| [INTERACT:poll] | 概念確認、意見調查、前測/後測 | 0–1 頁 |
| [VIZ] | 「前後對比」「格式轉換」「A 到 B 的演進」 | 0–1 頁 |
2. 建立專案目錄與基礎 HTML
使用者確認後：
- 建立專案目錄：
<當前工作目錄>/<簡報英文短名>/ - 建立
images/子目錄 - 生成
index.html（完整 Reveal.js 骨架）
讀取 references/reveal-template.md 獲得：完整 CSS 變數、元件樣式、Reveal.js 初始化程式碼。
命名規則：
- 專案目錄：kebab-case 英文（
ai-course、math-lesson） - Firestore 集合：
<slug>_wordcloud、<slug>_poll（避免不同簡報資料混用）
調色盤（所有簡報統一使用）：
--accent: #e8643a 橘紅（主強調）
--accent2: #4fc3f7 青（次強調）
--success: #81c784 綠（正面）
--warn: #ffb74d 琥珀（提示）
背景： #0d1117 ~ #1a1a2e（深暗色）
3. 生成背景底圖 [BG]
對每個 [BG] 頁面呼叫 draw 技能，可平行執行：
python "{{DRAW_SKILL_PATH}}" \
"<底圖 prompt>" \
--size 1536x1024 --quality low \
--name <slide-slug> \
--outdir "<專案目錄>/images"
{{DRAW_SKILL_PATH}}在安裝時由 install.py 自動替換為 draw.py 的實際路徑。
底圖 Prompt 設計原則：
- 深暗色系（deep navy、dark space、#0d1117 背景）
- 無文字
- 與投影片主題有關但抽象（概念視覺化，非字面圖示）
- 霓虹/發光效果，配合主題色
- 例：AI 課程封面 →
"deep navy background, glowing neural network nodes and light trails, cinematic wide, no text, abstract tech art"
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.
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.

html-slide-builder is a skill published in the GitHub repository mathruffian-dot/claude-html-slide-builder (22 stars, last pushed 4mo ago), licensed MIT. It adds 256 tokens to every session and 2,954 once invoked, about $0.0010 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 2026-08-30.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.

Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
