Each one drops into your agent and installs with a single command.
How do I install a Testing & Review skill or MCP server?
Open any listing and copy its one-line command - for example npx skills add https://github.com/owner/repo --skill name for a skill, or /plugin marketplace add owner/repo for a marketplace. It's available in your next Claude Code, Codex or Cursor session.
Which Testing & Review skills and frameworks are covered?
Jest, Playwright, Vitest, pytest and linting and more. Skillselion ingests the whole catalog from skills.sh, GitHub and the MCP registries, so new Testing & Review skills appear as the community ships them - ranked by installs and GitHub stars, never paid placement.
