agent-skills

Addy Osmani—yes, THE Addy Osmani, the Google engineer who's basically the Yoda of JavaScript performance—just dropped agent-skills on GitHub and it's already lighting up the trending page. This isn't another half-baked AI tool. It's production-grade engineering skills for AI coding agents. Think: prompt engineering, code generation patterns, testing strategies, deployment workflows—the actual skills that separate "looks like it works in my IDE" from "this is production-ready."

Every developer is building AI coding agents now. Most of them are hot garbage in production. agent-skills is Osmani's way of saying "here's how you actually build this stuff so it doesn't fall apart when real users touch it." It's the missing manual for engineering AI that ships. If you're building AI devs, this is probably the most valuable repo you'll see this month.
