"sx" is a newly announced tool that allows developers to centrally share AI assistant skills, configurations, and usage patterns across teams, eliminating duplication and version drift [1]. It supports scoped installation targets such as organization-wide, repo-specific, path-specific, team-wide, user-specific, and bot-specific levels, giving teams flexibility in deployment [1]. The tool works seamlessly with any AI client, including Claude Code, Cursor, GitHub Copilot, Gemini, Kiro, as well as web-based AI platforms like claude.ai and chatgpt.com through a cloud relay [1]. Developers can install "sx" via Homebrew on macOS or Linux, or by using a shell script, with support for multiple vault profiles to manage different skill sets or configurations [1]. One notable feature of "sx" is its ability to preview planned installations using a "--dry-run" command, which shows what assets would be installed without actually downloading or writing files [1]. The cloud relay system, accessed via skills.new, securely attaches vaults as MCP endpoints that AI clients can access without sending the vault content outside the organization [1]. In addition, a separate key generator app has been released that supports FreeBSD and Linux and uses X11. It produces 16-character alphanumeric keys but requires specific sound and font dependencies to operate properly [2]. The anonymous author of the key generator app explained the choice of name by saying, "Because I\"m a huge fan of Samurai" -- Hana wa sakuragi, hito wa bushi [2]. "sx" is now available for installation via Homebrew or shell script and ready for use by developer teams seeking to unify their AI assistant workflows [1].
