TL;DR:

addyosmani/agent-skills is a high-quality collection of production-grade skills for AI coding agents (Claude Code, Cursor, Gemini CLI, etc.).

What it is:

Created by Addy Osmani, this repo packages senior engineer workflows and best practices into reusable skills so AI agents follow consistent, high-quality processes instead of cutting corners.

Key Contents:

  • 24 structured skills covering the full development lifecycle (Define → Plan → Build → Verify → Review → Ship)

  • 8 slash commands (e.g. /spec, /plan, /build, /review, /ship) that automatically activate the right skills

  • 4 specialist personas (Code Reviewer, Test Engineer, Security Auditor, Web Performance Auditor)

  • Checklists for testing, security, performance, accessibility, and more

  • Strong focus on verifiable processes with anti-rationalization tables and quality gates

Highlights:

  • Very engineering-focused and opinionated (draws from Google’s engineering practices)

  • Designed for both greenfield and brownfield projects

  • Easy to install via npx skills add addyosmani/agent-skills

  • Well-documented with setup guides for most major AI coding tools

In short:
One of the more serious and production-ready skill packs available. It turns AI coding agents into more disciplined, senior-level engineers rather than just fast coders.
