Frontend Slides helps non-designers build web presentations by generating visual style previews first and letting the user choose a direction before the full deck is produced. It can also extract text, images, and notes from a PowerPoint file and rebuild them as a 16:9 HTML presentation with inline CSS and JavaScript. Optional scripts deploy the deck or export a static PDF; PowerPoint conversion requires Python and python-pptx.

kicad-happy gives Claude Code, Codex, and other agents workflows for parsing KiCad projects, checking nets, voltages, layouts, signal integrity, and EMC risks, and preparing component, BOM, and fabrication work. SPICE analysis requires a compatible simulator such as ngspice, LTspice, or Xyce. Distributor lookups can use optional API keys and otherwise fall back to web search.

Web Asset Generator creates favicons, app icons, and social sharing images from a logo, text, or emoji, then produces common sizes and checks file and accessibility requirements. It can detect frameworks such as Next.js or Astro and help integrate the assets. The scripts require Python 3.6+ and Pillow; emoji rendering uses optional dependencies.

Superdesign is a product-design skill for coding agents such as Claude Code, Cursor, and Codex. It reads the current interface and code context, gathers style references, establishes a reusable design system, and creates branchable HTML drafts on a design canvas for new pages or redesigns. The complete workflow also requires the Superdesign CLI and a login, and it is separate from the archived legacy VS Code extension.
