Addy Osmani's Agent Skills

Addy Osmani publishes this plugin from his own addy-agent-skills marketplace. We list it here because it’s a real set of engineering skills people search for. We didn’t write it and haven’t reviewed it.

Most of the skills follow a change from start to finish. You write a spec and a plan, build in small steps, and test each step. Then you review the code, debug what breaks, and get it ready to ship.

Others cover the parts that are easy to skip: security, speed, monitoring, docs, and a clean git history. Some help when you’re not sure what you want yet. One refines a rough idea. Another interviews you until the real ask is clear. A few keep your agent honest, like checking its work against official docs and holding it to a written quality bar.
