html-ppt-skill bets agents ship HTML decks with real presenter mode — 8.2k stars
A one-command MIT AgentSkill gives coding agents 36 themes, 31 layouts and a presenter window for HTML decks; 8.2k GitHub stars by September 2026.

What the business is
html-ppt-skill ('HTML PPT Studio') is a free MIT AgentSkill by lewis that lets agent runtimes such as Claude Code and Copilot CLI produce professional HTML presentations — 36 CSS-token themes, 15 full-deck templates, 31 single-page layouts, 47 animations and a presenter window with speaker script and timer — all pure static HTML/CSS/JS with no build step.
How it started
The repo launched on 2026-04-15 as 'a world-class AgentSkill for producing professional HTML presentations', built on the premise that an agent should output the finished artifact — a themed, animated deck with a real presenter view — rather than markdown that a human must reformat. Its stated design defaults are token-driven theming, iframe-isolated previews, zero build, and 'senior-designer' typography with Chinese and English as first-class languages.
What happened
Between April and September 2026 the skill expanded from the About blurb's 24 themes and 20+ animations to a README listing 36 themes, 15 full-deck templates, 31 single-page layouts and 47 animations, adding a presenter window with magnetic cards (current slide, next-slide preview, speaker script, timer), four showcase decks and 56 self-test screenshots. By the 2026-09-04 crawl the repository carried 8.2k stars, 707 forks and 21 commits.
How it ended up
Still live as of 2026-09-05 as an MIT-licensed, single-author open-source skill with 8.2k GitHub stars. The material describes no company, funding, pricing or revenue — it is an ecosystem bet on the AgentSkills format rather than a commercial venture.
Background
html-ppt-skill, branded HTML PPT Studio, is an MIT AgentSkill for producing HTML presentations. A single 'npx skills add' installs it into agent runtimes such as Claude Code and Copilot CLI, and requests like 'make an eight-page tech-sharing deck in cyberpunk theme' return a working presentation built from pure static HTML, CSS and JavaScript.
The bet is that presentation quality is a systems problem, not a prompt problem: the skill ships 36 CSS-token themes, 15 full-deck templates (pitch deck, product launch, weekly report, Xiaohongshu posts, course modules), 31 single-page layouts, 27 CSS animations and 20 canvas effects, plus a presenter window that keeps current slide, next-slide preview, speaker script and timer in sync via BroadcastChannel.
Pixel fidelity is handled by loading the same deck HTML in iframes with a ?preview=N query, so what the presenter sees is what the audience gets. Full-deck templates include 150–300-word speaker scripts per slide with explicit rules — prompt signals rather than scripts to read, two to three minutes per page, conversational prose.
By the 2026-09-04 crawl the repository showed 8.2k stars and 707 forks on 21 commits, with no company or monetization behind it. The project's About text (24 themes) has not caught up with its README (36 themes) — a minor signal that growth is outpacing documentation. As of 2026-09-05 it remains a single-author, free, MIT skill betting that the AgentSkills ecosystem will standardize how AI builds decks.
What has to be true
- It makes the agent's output presentable end-to-end — themes, layouts, animations and a speaker view — instead of leaving formatting to the human.
- One-command install through 'npx skills add' removed adoption friction for any AgentSkills-compatible runtime.
- iframe-based previews guaranteed that presenter view and audience view are the same pixels, solving a trust problem AI-generated slides usually have.
- Chinese and English as first-class languages with pre-imported Noto fonts widened the skill's reach beyond English-only deck tools.
- With 21 commits and no company or revenue disclosed, the skill is still a bet on ecosystem position rather than a business.
What can be applied
Give the agent the finished artifact, not an intermediate: if the output is a presentation, ship presenter tooling, design tokens and one-command install so 'decent' is the default.
Aftermath
As of 2026-09-05 html-ppt-skill is live as an MIT-licensed AgentSkill by lewis: 8.2k GitHub stars, 707 forks and 21 commits, with a README (English and Chinese) documenting 36 themes, 15 full-deck templates, 31 layouts, 47 animations, presenter mode and headless-Chrome PNG rendering. The project shows no company, funding or paid product — it remains a free open-source skill whose bet is that agents will become the default authors of presentations and that this design system will be among the formats they reach for.
