SkillHub is an open marketplace for AI agent skills — small, composable behaviour packs that drop into Claude Code, the Claude Agent SDK, or any other host that speaks the skill protocol. This post is the shortest useful tour: install the CLI, find a skill that matters to you, and publish your first one. The examples use a document-handling skill, but the same three commands work for anything in the catalog — backend helpers, React components, data tools, prompts.
Install the CLI
The CLI ships as an npx package — no global install needed. Check that it runs and see what is already installed locally:
npx skillhub --help npx skillhub list
Find a skill that matters to you
The catalog holds 72,000+ skills across 30 categories — from PDF and spreadsheet tooling to backend APIs, frontend components, and prompt libraries. Search by keyword and sort by aiScore to surface the skills an AI reviewer graded highest:
npx skillhub search "pdf" --sort aiScore --limit 5
Install, try, decide
Pick a result and install it by its full skill ID (owner/repo/skill-name). Skills land in ~/.claude/skills/ by default:
npx skillhub install anthropics/skills/pdf npx skillhub list
Targeting a different agent? Add --platform (claude, codex, copilot, cursor, windsurf). And if a skill is not what you wanted, remove it cleanly — no manual file deletion:
npx skillhub uninstall pdf
Publish your first skill
A skill is just a folder with a SKILL.md file at its root — a name, a description with trigger phrases, and the instructions themselves:
my-skill/ └── SKILL.md # name, description (with triggers), instructions
Push that folder to a public GitHub repository, then submit the repo URL on SkillHub at skills.palebluedot.live/claim. The crawler finds every SKILL.md in the repo, adds it to the catalog, and runs the AI review automatically — there is no separate publish command to remember.
Where to next
Open any skill’s page in the catalog to read its full AI review and per-criterion scores — the fastest way to learn what “good” looks like before you write your own. When you are ready to ship something polished, the Skill Spotlight category here is a good source of fully-worked examples.
