The 58K-Star Script Collection That Makes Your AI Coding Agent Do Everything

Addy Osmani just dropped a Shell script toolkit that the GitHub community starred 8,340 times in a single week. That number says more than any introduction could.

What Is agent-skills

agent-skills is a collection of production grade skills for AI coding agents, written in pure Shell. Each skill is a standalone script, you just copy it into your project and it runs right away. No framework setup, no long docs to read.

The repo currently sits at 58,158 stars and keeps climbing every day.

What's Inside

The script collection covers a few main areas:

Automated code review helps you catch bugs, code smells, and security issues before you push to remote. Smart refactoring analyzes a function's structure and suggests a cleaner rewrite. Testing automation generates test cases based on a function's signature. Deployment scripting handles CI/CD pipelines without you babysitting every step.

Each script runs independently, so you grab exactly what you need instead of pulling in the whole toolkit.

👤 Who Built It

Addy Osmani is a longtime Google Chrome engineer and the author of "Learning JavaScript Design Patterns," one of the most cited books in the JavaScript community for over a decade. He started digging deep into AI engineering workflows in 2024, and agent-skills is the result of real hands-on use, not a demo experiment.

Works With Claude Code and Cursor

Every script in the repo works as a slash command or custom skill inside Claude Code. You register the script in your agent's config file and call it by name.

With Cursor, the mechanism is similar, through .cursorrules or custom agent context. Average setup time is under 10 minutes based on community feedback.

Who It's For

Are you vibe coding with AI but still doing repetitive chores by hand, like reviewing PRs, writing tests, or checking lint? agent-skills solves exactly that problem. You don't need deep Shell knowledge either, since every script has comments explaining each step.

Developers who want more productivity without installing another heavy tool will find this collection useful from the very first run.
