What is html-ppt-presenter-mode?

A presentation template for HTML slides with a speaker view, five switchable themes, and a pop-up showing the current slide, next slide, script, and timer.

Use it to create technical talks, public presentations, and lessons where you may need a teleprompter or speaker notes.

It helps speakers follow prepared notes and keep track of timing without putting private prompts on the audience’s slides.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00095	$0.01147
Opus 5	$0.00048	$0.00574
Sonnet 5	$0.00019	$0.00229
Haiku 4.5	$0.00010	$0.00115

Security

Grade A, and why

html-ppt-presenter-mode 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.

Origin

This is a copy

91% identical to html-ppt-course-module — 36 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HTML PPT · Presenter Mode (演讲者模式)

A focused entry point into the html-ppt master skill that lands the user directly on the presenter-mode-reveal full-deck template.

When this card is picked

The Examples gallery wires "Use this prompt" to the example_prompt above. When you accept that prompt, this card is the right pick if the user wants exactly the visual identity of presenter-mode-reveal (see the upstream full-decks catalog for screenshots and rationale).

How to author the deck

Read the master skill first. All authoring rules live in skills/html-ppt/SKILL.md — content/audience checklist, token rules, layout reuse, presenter mode, the keyboard runtime, and the "never put presenter-only text on the slide" rule.
Start from the matching template folder: skills/html-ppt/templates/full-decks/presenter-mode-reveal/ — copy index.html and style.css into the project, keep the .tpl-presenter-mode-reveal body class.
Bring the shared runtime with the template. The upstream index.html links the shared CSS/JS via ../../../assets/... because it sits three folders deep inside skills/html-ppt/templates/full-decks/. Once you copy index.html into the project, those parent-relative URLs no longer resolve and base.css, animations.css, and runtime.js will 404 — meaning the deck never activates and slide navigation is dead. Pick one of these two recipes per project:
- Recipe A — copy + rewrite (preferred): copy skills/html-ppt/assets/fonts.css, skills/html-ppt/assets/base.css, skills/html-ppt/assets/animations/animations.css, and skills/html-ppt/assets/runtime.js into a project-local assets/ (with assets/animations/animations.css), then rewrite the four <link>/<script> tags in index.html from ../../../assets/... to the matching project-local paths (assets/fonts.css, assets/base.css, assets/animations/animations.css, assets/runtime.js).
- Recipe B — inline: read the same four files and replace each <link rel="stylesheet" href="../../../assets/..."> with a <style>...</style> containing the file's contents, and the <script src="../../../assets/runtime.js"> with a <script>...</script> containing runtime.js. Yields a single self-contained index.html. Either way, do not ship the upstream ../../../assets/... URLs verbatim into a project artifact — they only work in-tree.
Pick a theme. Default tokens look fine; if the user wants a different feel, swap in any of the 36 themes from skills/html-ppt/assets/themes/*.css via <link id="theme-link"> and let T cycle.
Replace demo content, not classes. The .tpl-presenter-mode-reveal scoped CSS only recognises the structural classes shipped in the template — keep them.
Speaker notes go inside <aside class="notes"> or <div class="notes"> — never as visible text on the slide.

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.
