Frontend Slides

A coding-agent skill for creating stunning HTML presentations — from scratch or by converting PowerPoint files. It is packaged as a Claude Code plugin, and the core SKILL.md can also be read by other coding agents with filesystem and shell access.

What This Does

Frontend Slides helps non-designers create beautiful web presentations without knowing CSS or JavaScript. It uses a "show, don't tell" approach: instead of asking you to describe your aesthetic preferences in words, it generates visual previews and lets you pick what you like.

Here is a deck about the skill, made through the skill:

https://github.com/user-attachments/assets/ef57333e-f879-432a-afb9-180388982478

Key Features

• Zero Dependencies — Single HTML files with inline CSS/JS. No npm, no build tools, no frameworks.
• Visual Style Discovery — Can't articulate design preferences? No problem. Pick from generated visual previews.
• PPT Conversion — Convert existing PowerPoint files to web, preserving all images and content.
• Anti-AI-Slop — Curated distinctive styles that avoid generic AI aesthetics (bye-bye, purple gradients on white).
• Bold Template Pack — Optional design-forward templates from beautiful-html-templates, loaded progressively so safe presets still work as the default fallback.
• Production Quality — Accessible, fixed 16:9, well-commented code you can customize.

Installation

Via Claude Code Custom Marketplace Source

Install directly from this public GitHub repo. Run these as two separate Claude Code messages; do not paste both lines into the prompt at once.

/plugin marketplace add https://github.com/zarazhangrui/frontend-slides

After that finishes, run:

/plugin install frontend-slides@frontend-slides

Use the HTTPS URL. The shorter zarazhangrui/frontend-slides form may make Claude Code try SSH, which can fail if GitHub is not already in your known_hosts file.

Then use it by typing /frontend-slides:frontend-slides in Claude Code. Claude Code namespaces plugin-installed skills as /plugin-name:skill-name.

Claude Code Manual Installation

Copy the skill files to your Claude Code skills directory:

# Create the skill directory
mkdir -p ~/.claude/skills/frontend-slides/scripts

# Copy the user-facing skill files
cp SKILL.md STYLE_PRESETS.md viewport-base.css html-template.md animation-patterns.md ~/.claude/skills/frontend-slides/
cp -R bold-template-pack ~/.claude/skills/frontend-slides/
cp scripts/extract-pptx.py scripts/deploy.sh scripts/export-pdf.sh ~/.claude/skills/frontend-slides/scripts/

Or clone directly:

git clone https://github.com/zarazhangrui/frontend-slides.git ~/.claude/skills/frontend-slides

Then use it by typing /frontend-slides in Claude Code. Standalone skills are not namespaced.

Other Coding Agents

Agents such as Codex, Kimi Code, OpenCode, Gemini CLI, or other local coding assistants can use the same core skill. The simplest path is to send the agent this GitHub repo link and ask it to use the Frontend Slides skill:

https://github.com/zarazhangrui/frontend-slides

If the agent can read GitHub repos or browse files, it should start from SKILL.md and load only the referenced support files it needs:

• STYLE_PRESETS.md
• viewport-base.css
• html-template.md
• animation-patterns.md
• bold-template-pack/
• scripts/

Some agents can also install the skill for you if they have filesystem access and a known local skills directory. If not, they can still follow SKILL.md directly for the current session.

The Claude Code plugin gives Claude Code a custom marketplace-source install flow and /frontend-slides:frontend-slides command. Other agents usually do not use that command surface.

Usage

Create a New Presentation

/frontend-slides:frontend-slides

> "I want to create a pitch deck for my AI startup"

If installed manually as a standalone Claude Code skill, use /frontend-slides instead.

In non-Claude agents, ask the agent to use the Frontend Slides skill and point it at this repo or SKILL.md.

The skill will:

1. Ask about your content (slides, messages, images)
2. Generate 3 visual style previews for you to compare, inferring the vibe from your brief unless you already named one
3. Let you pick the visual direction
4. Create the full presentation in your chosen style
5. Open it in your browser

Convert a PowerPoint

/frontend-slides:frontend-slides

> "Convert my presentation.pptx to a web slideshow"

The skill will:

1. Extract all text, images, and notes from your PPT
2. Show you the extracted content for confirmation
3. Let you pick a visual style
4. Generate an HTML presentation with all your original assets

Bold Template Pack

The skill also includes 34 optional bold design systems from beautiful-html-templates, such as Neo-Grid Bold, Editorial Tri-Tone, Creative Mode, Broadside, Signal, and Vellum.

During style discovery, the preview set is:

• 1 safe preset from STYLE_PRESETS.md
• at least 1 bold template option from bold-template-pack/selection-index.json
• 1 wildcard option, either another bold template or a self-generated custom design

The agent reads the compact bold template index first, then loads only the shortlisted candidates' small preview.md cards for title-slide previews. It loads the full design.md for exactly one bold template only after the user picks that template for the final deck. If the user picks a custom wildcard, the agent expands that preview's own CSS and layout system into the full deck.

Bold Template Gallery

Frontend Slides can now draw from the 34 bold design systems in beautiful-html-templates. Three screenshots per template show how each visual system handles different slide layouts. Click any template name to inspect the source template library.

Architecture

This skill uses progressive disclosure — the main SKILL.md is a workflow map, with supporting files loaded on-demand only when needed:

File	Purpose	Loaded When
SKILL.md	Core workflow and rules	Always (skill invocation)
STYLE_PRESETS.md	12 curated visual presets	Phase 2 (style selection)
bold-template-pack/selection-index.json	Compact bold template metadata	Phase 2 (candidate selection)
bold-template-pack/templates/*/preview.md	Tiny style cards for shortlisted bold previews	Phase 2 after shortlisting
bold-template-pack/templates/*/design.md	Full design system for the selected bold template	Phase 3 after user selection
viewport-base.css	Mandatory fixed-stage CSS	Phase 3 (generation)
html-template.md	HTML structure and JS features	Phase 3 (generation)
animation-patterns.md	CSS/JS animation reference	Phase 3 (generation)
scripts/extract-pptx.py	PPT content extraction	Phase 4 (conversion)
scripts/deploy.sh	Deploy to Vercel	Phase 6 (sharing)
scripts/export-pdf.sh	Export slides to PDF	Phase 6 (sharing)

Maintenance-only source metadata and regeneration helpers live outside the user-facing skill package. Normal users do not need them.

This design follows agent-skill best practices: give the agent a map first, then reveal only the specific files needed for the current choice.

Philosophy

This skill was born from the belief that:

1. You don't need to be a designer to make beautiful things. You just need to react to what you see.

2. Dependencies are debt. A single HTML file will work in 10 years. A React project from 2019? Good luck.

3. Generic is forgettable. Every presentation should feel custom-crafted, not template-generated.

4. Comments are kindness. Code should explain itself to future-you (or anyone else who opens it).

Sharing Your Presentations

After creating a presentation, the skill offers two ways to share it:

Deploy to a Live URL

One command deploys your slides to a permanent, shareable URL that works on any device — phones, tablets, laptops:

bash scripts/deploy.sh ./my-deck/
# or
bash scripts/deploy.sh ./presentation.html

Uses Vercel (free tier). The skill walks you through signup and login if it's your first time.

Export to PDF

Convert your slides to a PDF for email, Slack, Notion, or printing:

bash scripts/export-pdf.sh ./my-deck/index.html
bash scripts/export-pdf.sh ./presentation.html ./output.pdf

Uses Playwright to screenshot each slide at 1920×1080 and combine into a PDF. Installs automatically if needed. Animations are not preserved (it's a static snapshot).

Requirements

• A local coding agent with filesystem access and the ability to run shell commands
• Claude Code is required only for the custom marketplace-source install and /frontend-slides:frontend-slides command
• For PPT conversion: Python with python-pptx library
• For URL deployment: Node.js + Vercel account (free)
• For PDF export: Node.js (Playwright installs automatically)
