Show HN: Sx 2.0 – Share AI skills with your team through a Dropbox folder

Sx 2.0 is a new desktop application that allows teams to share AI skills and configurations through shared cloud folders like Dropbox, eliminating the need for command-line knowledge or git expertise. The app automatically translates and installs AI assets across multiple AI clients (Claude, Cursor, Copilot, etc.) when users sync their shared folder, making AI skill-sharing accessible to non-technical teams in marketing, legal, sales, and operations. The tool stores skills as readable markdown files that can be synced through existing file-sharing services, with the app handling the technical work of format conversion and installation.
