What is ASG?

ASG (Agent Skill Generator) is a free, open-source app that lets you build structured AI agent skills directly in your browser. It requires no sign-ups, no accounts, and no cloud services—just bring your own API key (BYOK) and start creating. Skills are defined in a clean SKILL.md format, and everything runs 100% privately on your computer. The tool is MIT licensed, meaning you own what you build and can share it however you choose.
