The 23 Best Claude Skills to Install in 2026 🛠️

Claude is already smart, but skills make it an expert. Skills are plug-and-play instruction files that give Claude superpowers it does not have out of the box. Each skill teaches Claude a specific workflow, set of rules, or domain expertise. Once installed, Claude automatically knows when to use the skill.

Install a marketing skill and Claude becomes a marketing strategist. Install a design skill and it becomes a UI/UX professional. Install a video skill and it builds entire videos from a single prompt.

This takes about 10 seconds. You don't need to download anything.

Grab the GitHub link underneath any skill below, paste it into Claude, and say:

That's it. Claude knows how to do the rest. It'll go read the repo, pull the skill file, and install it for you. No downloads, no dragging files around, no accounts, no signups.
