Description

Agent Skills is a curated collection of production-grade engineering skills for AI coding agents, maintained by Addy Osmani, providing battle-tested best practices and operational conventions.

Key Features

  • 23 engineering skills — Covers full dev lifecycle: spec definition, planning, building, testing, review, simplification, and shipping
  • 7 slash commands — /spec, /plan, /build, /test, /review, /code-simplify, /ship for different dev phases
  • Multi-tool compatibility — Supports Claude Code, Cursor, Gemini CLI, Windsurf, OpenCode, GitHub Copilot, and more
