Sx is an open-source package manager designed for teams using AI coding assistants. It treats AI configurations—custom skills, MCP server configs, slash commands, hooks, agents, and coding standards—as versioned packages that can be centrally managed, scoped, and shared across an organization.

Why Sx?

The problem: top developers create effective AI setups (prompts, MCPs, commands) but those remain siloed on their machines. Current workarounds—copying into each repo (duplication, drift), global configs (context bloat), or manual plugin installs (client lock-in)—don't scale. Sx solves this by treating AI assets as sharable packages with scoped installation.

Quickstart

# macOS/Linux via Homebrew
brew tap sleuth-io/tap
brew install sx

Or via shell script
curl -fsSL https://raw.githubusercontent.com/sleuth-io/sx/main/install.sh | bash
Initialize and add assets
sx init
sx add /path/to/my-skill
sx install

Scoped Installation

Assets can be installed for specific scopes, avoiding context bloat:

• sx install my-skill --org – everyone in the vault
• sx install my-skill --repo github.com/acme/infra – only inside that repo
• sx install my-skill --path github.com/acme/infra#docs/ – a specific path
• sx install my-skill --team platform – team members
• sx install my-skill --user [email protected] – a single user
• sx install my-skill --bot python-backend – a CI/agent identity

Use sx install --dry-run to preview what would be installed.

Cloud Relay

Expose your vault to Claude.ai or ChatGPT via MCP using the skills.new relay:

sx cloud connect
sx cloud serve
sx cloud status

The relay opens a WebSocket tunnel—vault content stays local.

Analytics & Audit

Track adoption and changes:

sx stats
sx stats --since 7d --json
sx audit --actor [email protected] --since 30d --event install.set

Works with Existing Claude Code Setups

If you have skills in ~/.claude, sx can version and sync them:

sx add ~/.claude/commands/my-command
sx add ~/.claude/skills/my-skill
sx add code-review@claude-plugins-official

Sx auto-detects the asset type (skill, command, MCP, agent, hook, rule) and wraps the files with metadata without modifying them.

Sx supports multiple vaults via profiles (sx profile add work, sx profile use work) and works with any AI client that supports MCP or file-based configs—Claude Code, Cursor, GitHub Copilot, Gemini, Kiro, and more.
