- Sx 2.0 ships as a native desktop app for Mac, Windows, and Linux that points at a shared Dropbox, Google Drive, OneDrive, or iCloud folder, letting teammates drag in markdown skills that auto-sync to each user's AI client with no server or accounts.
- Sx's creator reframed the product after running roughly 60 discovery interviews this year, finding that marketing, legal, sales, and ops teams — not developers — are now writing the best AI skills, and have no interest in
gitor the command line. - Vault format v2 stores every asset as plain readable markdown in
assets/<name>/with version history in.sx/versions/, making vaults greppable, Obsidian-compatible, and usable directly by clients like Claude Code without unpacking. - The app's Sync button runs an
sx installunder the hood that resolves dependencies, translates each asset into the right format for Claude Code, Cursor, Copilot, Codex, Gemini, Cline, and Kiro, and writes it to the correct location on the machine. - Sx 2.0's extension system treats plugins as folders with a manifest and one ES module, ships fifteen extensions in its marketplace, and is permission-gated with a plain-language capability list that re-prompts on any update that changes it.
- Featured marketplace extensions include Collection Doctor (0–100 scoring for thin, stale, duplicated, or oversized skills), adoption widgets, Review Rota for rotating review due dates, and Collection Export to Claude Code, Codex, or Gemini plugin formats.
- The project remains Apache-2.0 on GitHub at
github.com/sleuth-io/sx, with the CLI still available viabrew install sxand the app shipped in release assets for all three platforms.
Why it matters: The release concedes that the CLI-only version of sx was leaving the highest-value skill authors — non-developers — out of the loop, and bets that hiding an entire package manager behind a single Sync button is what unlocks team-wide AI skill distribution; developers gain native client support for seven AI tools but lose nothing, since the Go binary and existing git/skills.new vault types continue to work.
