Agent Skills
A production-grade engineering skill library that organizes agent work across specification, planning, implementation, testing, review, and shipping.
What is Agent Skills?
Addy Osmani's Agent Skills packages senior engineering workflows and quality gates for AI coding agents. The current repository includes skills, specialized agents, and lifecycle commands that move work from specification and planning through incremental implementation, testing, review, simplification, security, and release. It supports multiple coding agents, including Claude Code, Codex, Cursor, Copilot, and Gemini CLI.
Best for
Software teams that want reusable, verification-first workflows and consistent quality gates across the complete development lifecycle.
Not for
Teams looking specifically for an Andrej Karpathy-authored or endorsed collection; this repository presents its own production engineering system.
