agent-skills

Good for

• Cover the development lifecycle with commands like /spec, /plan, /build, /test, /review and /ship
• Work test-first, building one small slice at a time and committing each task
• Review code before merge with /review and audit web performance with /webperf
• Designing an API or frontend UI triggers the matching skill automatically

Getting started

1. Run npx skills add addyosmani/agent-skills for all 25 skills, or add --skill for a single one
2. In Claude Code run /plugin marketplace add addyosmani/agent-skills, then /plugin install agent-skills@addy-agent-skills
3. Start with the relevant slash command; where it clashes with a built-in, use the namespaced form such as /agent-skills:review
4. Once a spec exists, /build auto implements every task in one approved pass

Before you install

Compatible with Claude Code, Cursor, Codex, Copilot and 70+ agents. Installing a single skill skips the repo-level references directory, so some shared checklist paths are unavailable.
