Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
pencil-dev-skill
Teaches AI coding tools to design and edit pencil.dev UI files (.pen format) through the Pencil MCP server. Every read and write goes through the MCP for schema validation. Live screenshots show the design as it looks, and the MCP keeps your changes and the editor in sync while the canvas is open. Recognises pencil.dev signals automatically: mentions of .pen, .lib.pen, the Pencil canvas, or a design-system folder all activate the skill. Works with Claude Code, Codex, Gemini CLI, Copilot CLI, and Cursor. Supports designing screens from scratch, editing existing canvases, instantiating components from .lib.pen libraries, customising design tokens, and bulk-replacing properties across a project.
Superdesign
Design or redesign frontend UI and marketing graphics on the Superdesign infinite canvas. Reads your codebase for context, sets up a design system, and generates branchable design drafts you refine.
