Skillselion

Skillselion is a directory of thousands of community-vetted Claude Code skills, each a real SKILL.md plus bundled scripts and references, ranked by install count so the best-tested skills rise to the top. Instead of guessing at prompts or reinventing a workflow, developers search or semantically browse the catalog, compare ranked candidates for their task, and load the right skill straight into Claude Code via the Skillselion MCP server. Coverage spans the long tail of real engineering work: tests, frontend, APIs, databases, infra, CI, and fast-moving SDKs. Free to use.
