Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit", "/commit", or invokes /caveman-commit. Auto-triggers when staging changes.
Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".
Tailwind CSS utility-first CSS framework. Use when styling web applications with utility classes, building responsive designs, or customizing design systems with theme variables.
React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

Electron embeds Chromium and Node.js so you can ship one JavaScript codebase for Windows, macOS, and Linux. Use these skills when scaffolding projects, wiring main/renderer IPC, configuring security and packaging, or integrating native modules and auto-updates.
The skill is based on Electron (latest), generated at 2026-01-30.
