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.

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

After that finishes, run:

text
/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:

bash
# 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:

bash
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:

text
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

text
/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

text
/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.

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 for candidate selection Phase 2 (style 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
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
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)

Overview (`bold-template-pack/README.md`)

Bold Template Pack

This pack brings the beautiful-html-templates design systems into the
frontend-slides skill without making them the default for every deck.

What To Read

  1. Read bold-template-pack/selection-index.json first.
  2. Shortlist candidates from metadata only:
    • mood
    • tone
    • best_for
    • avoid_for
    • formality
    • density
    • scheme
  3. For title-slide previews, read only the relevant candidate preview.md
    files.
  4. After the user chooses a bold template, read exactly that one template's
    full design.md.
  5. Do not read every design.md in the pack.
  6. Do not read or copy template.html from the source template library unless a
    selected design.md is missing a critical implementation detail.

The full source metadata index is not bundled in the user-facing skill. Normal
generation should use selection-index.json only.

How To Use In Frontend Slides

Preview mix:

  • 1 safe option from STYLE_PRESETS.md
  • at least 1 bold option from this pack
  • 1 wildcard option, which may be another bold template from this pack or a
    self-generated custom design

Adjust the tone inside that default mix:

  • For board, legal, regulatory, healthcare, investor-update, or highly formal
    internal decks, make the safe option very restrained and choose calmer,
    higher-formality bold templates. The wildcard should feel authoritative and
    specific, not merely decorative.
  • For bold, editorial, expressive, experimental, or highly designed decks, keep
    the safe option as a readable fallback, choose one strong bold template, and
    use the wildcard for either a second adventurous template or a custom design
    that better matches the user's occasion and vibe.

If the wildcard is custom, it must follow Frontend Slides' no-slop aesthetics:
distinctive typography, a committed palette, a recognizable layout system, a
context-specific visual idea, fixed 16:9 stage behavior, and no visible process
labels such as "custom", "wildcard", "template", or "preview".

Implementation Contract

design.md is the design-system reference. Treat it as a style recipe, not as
content to copy. preview.md is only a lightweight style card for generating
the three title-slide options.

Preview slides must be real title slides for the user's deck. Do not render
template names, option labels, file names, paths, preview.md, "generated
from", or user requirement notes on the slide itself.

When generating final slides:

  • Keep frontend-slides output as one self-contained HTML file.
  • Include the full contents of viewport-base.css.
  • Generate every deck as a fixed 1920×1080 stage scaled uniformly to the
    viewport. This applies even if the source template was originally
    viewport-fluid.
  • Treat vw, vh, and clamp() values in a source design.md as design
    proportions to translate into fixed 1920×1080 stage coordinates.
  • Preserve the selected template's fonts, palette, decorative vocabulary,
    spacing rhythm, and component grammar.
  • Keep the user's actual slide content primary. The template style should shape
    presentation, not override message or structure.
  • Verify rendered output for both text overflow and panel overlap. A card can
    pass scrollHeight checks while still being covered by another grid panel.
