I built npx build-skill for your agent skills

Hey everyone! Just shipped Build Skill, a CLI that scaffolds AI agent skill repositories in one command.

I kept running into the same friction when creating skills: every time I wanted to create a new skills repo, I was manually wiring up folder structures, marketplace configs, GitHub Actions workflows, sync scripts — the same tedious boilerplate every time. None of it is hard. All of it is annoying. And if you get the structure wrong, your skills just silently don't work; no error, no feedback, just an agent that doesn't pick up what you built.

I caught myself copy-pasting from old repos more than once, and that's usually my signal that something should be automated.

So I built Build Skill:

npx build-skill

You answer a few prompts and get a complete, spec-compliant skills repository — ready to publish and compatible with Claude Code, Cursor, Codex, and 35+ other agents. It includes CI/CD for validation, helper scripts to add new skills, and a quiet mode for CI pipelines.

It's like create-react-app, but for AI agent skills.

Would love any feedback and curious what skills you're all building for your agents.
