Coding agents can now build HTML slides with actual taste

What it does

Frontend Slides is a prompt-and-template pack that teaches coding agents—Claude Code, Codex, Gemini CLI, and others—to generate single-file HTML presentations. You describe your content, the agent renders three visual previews, you pick a direction, and it emits a complete 16:9 deck with inline CSS and JavaScript. It also ingests existing PowerPoint files and rewraps their text, images, and notes in whatever style you chose.

The interesting bit

The project treats taste as a selection problem, not a generation problem. Instead of trusting you to describe aesthetics with words like “professional” or “modern”—which LLMs reliably translate into purple gradients—it forces the agent to show preview cards first. The “Anti-AI-Slop” curation deliberately sidesteps generic AI aesthetics, and the optional bold template pack pulls from 34 distinct design systems that load progressively so the agent only fetches the one you pick.

Key highlights

• Zero-dependency output: every deck is one HTML file with inline CSS/JS. No package managers, no build tools, no frameworks.
• Visual Style Discovery: the agent generates previews before committing to a full deck.
• PowerPoint conversion: extracts content from .pptx files and rewraps it in your chosen web-native style.
• Multi-agent support: works as a Claude Code plugin, but any agent with filesystem and shell access can read the core SKILL.md.
• Progressive templates: 34 optional bold design systems from beautiful-html-templates are indexed lightly and expanded only after selection.

Verdict

Worth a look if you want presentation decks without touching Figma, PowerPoint, or a build pipeline. Skip it if you already have a design system you love and don’t need an agent middleman.
