# Agent Skills **Production-grade engineering skills for AI coding agents.** Skills encode the workflows, quality gates, and best practices that senior engineers use when building software. These ones are packaged so AI agents follow them consistently across every phase of development.  --- ## Commands 7 slash commands that map to the development lifecycle. Each one activates the right skills automatically. | What you're doing | Command | Key principle | |-------------------|---------|---------------| | Define what to build | `/spec` | Spec before code | | Plan how to build it | `/plan` | Small, atomic tasks | | Build incrementally | `/build` | One slice at a time | | Prove it works | `/test` | Tests are proof | | Review before merge | `/review` | Improve code health | | Simplify the code | `/code-simplify` | Clarity over cleverness | | Ship to production | `/ship` | Faster is safer | Skills also activate automatically based on what you're doing — designing an API triggers `api-and-interface-design`, building UI triggers `frontend-ui-engineering`, and so on. --- ## Quick Start <details> <summary><b>Claude Code (recommended)</b></summary> **Marketplace install:** ``` /plugin marketplace add addyosmani/agent-skills /plugin install agent-skills@addy-agent-skills ``` > **SSH errors?** The marketplace clones repos via SSH.
