Claude Skills are plug-in instruction sets that turn Claude into a specialist on demand — a marketer, an SEO auditor, a financial modeller, a sales researcher — without you having to write a single prompt template. Install one, and Claude knows exactly how to handle that class of work.

The ecosystem has exploded over the past year, and it’s hard to know where to start. So I’ve put together a curated guide of the most useful Claude Skills for business, organized into five categories: Productivity, Marketing & SEO, Sales & Business, Office & Docs, and Dev & Automation. Each entry includes a short description and a direct link to the source repository, so you can install and start using them straight away.

Whether you run a lean startup, a marketing team, or a growing agency, this list will save you hours of hunting through GitHub.
