The Claude skills that I use and the only ones you need

Want help applying this to your idea? Tell me what you are trying to build and where you are stuck.

There are over 60,000 agent skills out there. Most are noise. I tested over 200 and pulled from the best curated repositories to find the exact skills that transform design, coding, marketing, and research.

How Skills Work (And How to Install Them in 10 Seconds)

A skill is a modular folder containing a SKILL.md file with battle-tested workflows, scripts, and constraints. Your agent scans lightweight metadata (~100 tokens) and only loads the full instructions when your task matches.

You can install any GitHub skill globally across Claude Code, Antigravity, Cursor, and Windsurf with a single command:
