Anthropic open-sourced 16 skills for Claude (PDF generation, MCP servers, frontend design, etc.) but there's no easy way to discover or use them.
Built a simple CLI:
pip install askill
skill browse # paginated list of all skills
skill search mcp # find by keyword
skill use pdf # install to your project
It clones their repo and parses SKILL.md files. ~300 lines of Python.
