uberSKILLS is an open-source web app that gives you an integrated authoring environment for Agent Skills:

- AI-assisted creation - describe what you want in plain English, get a complete SKILL.md draft - Structured editor - edit metadata, instructions, and file templates with real-time validation - Multi-model testing - test your skill against any model on OpenRouter (Claude, GPT-4, Gemini, Llama, etc.) with streaming responses and token metrics - One-click deploy - deploy to 8 agents: Antigravity, Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode, and Windsurf - Import/export - bulk-import existing skills from directories or zips, export as zip - Version history - every edit is versioned automatically

Get started with a single command, no setup required:

npx @uberskillsdev/uberskills

Tech stack: Next.js 15, TypeScript, SQLite + Drizzle ORM, Vercel AI SDK, shadcn/ui, Tailwind CSS v4. Everything runs locally your data stays on your machine, API keys are encrypted with AES-256-GCM, and there's no account or cloud dependency.
