The Best Claude Code Skills, Tested and Rated

The Claude Code skills worth installing right now are the Agentic SEO Skill for any team doing SEO or GEO work, and n8n Skills for teams that automate with n8n. Both run with the full Claude Code feature set, and both carry a note on how they behave if you also run Codex or OpenCode. That cross-agent column is what separates this list from a generic top-ten post.

We rate by role rather than by raw popularity, because the best skill for a marketing team is rarely the best one for engineering. Each pick gets a one-line verdict you can act on without reading a review.

How we pick

1. Solves a real, recurring job for a SaaS or product team.
2. Runs reliably in Claude Code, with full use of allowed-tools, hooks, MCP, and bundled scripts where the skill needs them.
3. Maintained source, honest install, and a clear note on cross-agent behavior.

This is a curated shortlist, not a 1.2 million skill dump. Compatibility states are AI-inferred today and flagged as not yet hand-verified. We would rather be honest about what we have not tested than guess green.
