Questions and answers
Are Claude Code skills free?
Every listed skill is published in a public GitHub repository and costs nothing to download. In the October 22, 2026 snapshot, 3,478 use an open license and name no paid service, 287 use an open license but connect to an outside service, 80 allow non-commercial use only and 26 use restricted terms.
How does the directory decide a skill needs a service?
For skills with full pages, from the install record the refresh reads from the skill's files: environment variables, MCP servers, outside hosts and HTTP clients. For other skills, from the compatibility line the author wrote in SKILL.md.
Can I use these skills in commercial work?
Skills under open-source or open-content licenses allow it under their terms. Non-commercial licenses do not, and restricted licenses need the publisher's permission. Each listing links to its license file.
