Set up and review Frontend Slides safely

What Frontend Slides is and why it is used

Frontend Slides is a Claude Code skill by developer zarazhangrui, whose source lives in the GitHub repository zarazhangrui/frontend-slides and which is packaged as a Claude Code plugin. According to the provider, the skill generates animation-rich HTML presentations that run entirely in the browser without any external dependencies, build tools, or npm packages, either built from scratch or converted from existing PowerPoint files. The skill is explicitly aimed at users without a design background and follows a visual selection process: instead of answering abstract style questions, the user is shown several finished style previews to choose from. This matters because traditional presentation software often forces a choice between very generic default templates or time-consuming design work, whereas a single, portable HTML file remains functional long-term without depending on the availability of any particular software.

Prerequisites

The skill requires a local coding agent with filesystem access and the ability to run shell commands; according to the documentation, Claude Code is required for full functionality, including the marketplace-source install and the /frontend-slides:frontend-slides command, while the core SKILL.md can generally also be read by other coding agents with comparable capabilities. Converting existing PowerPoint files additionally requires Python with the python-pptx library. Anyone who wants to publish the finished presentation at its own URL needs Node.js plus a free Vercel account, and PDF export requires Node.js together with Playwright, which according to the provider installs automatically when needed.

Setting it up step by step

Installation happens via the Claude Code plugin marketplace or by directly pulling the repository into a project's skills directory. After installation, the skill runs through several phases: first it detects whether a new presentation should be created, an existing PowerPoint file converted, or an existing HTML presentation revised. For a new presentation, the skill asks all at once about purpose, desired length, available content, and whether the deck is meant to be read aloud during a talk or read independently. It then generates three different style previews as individual HTML slides for the user to choose from, before producing the full presentation in a fixed 16:9 format at an internal resolution of 1920 by 1080 pixels. Finally, the finished presentation can be deployed to Vercel using a script or exported to PDF with another script.

Security and best practices

Since the generated presentations are self-contained HTML files with embedded CSS and JavaScript, they run entirely locally in the browser and require no server-side execution, which reduces the risk of typical web security vulnerabilities. Anyone using the deploy feature should be aware that the presentation ends up at a publicly reachable Vercel URL unless an access restriction is set up, and should therefore avoid including confidential information if the URL is not protected. The provider also emphasizes fixed design constraints such as the non-negotiable 16:9 stage format, so content is never distorted or rearranged on any device, something to keep in mind during manual edits so the consistency is not broken.

A practical example and its limits

A typical use case is a startup pitch deck where the user provides only rough notes, the skill proposes a set of slides with matching typography, color scheme, and animations, and the finished presentation is then published directly via the deploy script. The limits are that the skill specializes in pure HTML presentations and does not cover complex interactive elements such as forms with backend connections; in addition, animations survive PDF export only as a static snapshot, meaning any motion is lost. For users who need traditional presentation software with offline editing outside of a coding agent, the skill is therefore less suitable.
