Agent Skills by Addy Osmani
Self
Open-source tool. Self-hosted setup.
Production-grade engineering skills for AI coding agents.
Maintained by Google Chrome engineering lead Addy Osmani, this collection focuses on the practices that separate demo code from shippable code — performance, testing rigor, and code review discipline. It's a widely cited reference for what a serious, professionally maintained skill pack should contain.
- Author-vetted engineering practices, not community-scraped content
- Emphasis on production readiness: testing, performance, review workflows
- Compatible with Claude Code and other Agent-Skills-standard harnesses
- MIT licensed, actively maintained
Things to Know About Self-Hosted
Self-hosted tools are open-source apps you install on your own server to replace SaaS products. You get full control and often zero license cost, but you're responsible for setup, security, backups, and uptime.
- Caution: You might need capable hosting or a VPS
- Caution: Setup requires technical experience
- Caution: You manage updates and patches
- Caution: Security and backups are your job
- Caution: Uptime depends on your server
- Caution: Scaling may need extra work
