agent-skills
Production-grade engineering skills for AI coding agents.
Agent Skills is a comprehensive collection of 24 production-grade engineering workflows designed to guide AI coding agents through the complete software development lifecycle. Created by Addy Osmani, it packages senior-level best practices, quality gates, and structured processes into reusable skill modules that agents can follow consistently. The pack covers everything from requirements gathering and spec writing to test-driven development, code review, security hardening, and production deployment, ensuring AI agents apply the same discipline that experienced engineers bring to production code.
