The repo has no top-level licence; each skill folder carries its own LICENSE.txt, and the document skills say use is governed by your agreement with Anthropic, so nothing is copied here. | | | | --- | --- | | Upstream | [anthropics/skills](https://github.com/anthropics/skills) | | License | per-skill LICENSE.txt (Anthropic terms for most) | | Author | anthropics | | Stars (at fetch) | 175,511 | | Fetched | 2026-09-10 | ## Install - Claude Code: `/plugin marketplace add anthropics/skills`.
