sx

sx

sx is a package manager for AI coding assistants. Create, version, and distribute reusable AI tools across your entire team. Think NPM for AI agents -- install once, use everywhere.

Why sx?

• Onboard new developers instantly with your team's tribal knowledge
• Expand successful AI use from experts to everyone
• Spread best practices to any AI tool (coming soon)

Quickstart

curl -fsSL https://raw.githubusercontent.com/sleuth-io/sx/main/install.sh | bash

then

# Initialize
sx init

# Add an asset from your vault
sx add /path/to/my-skill

# Install assets to your current project
sx install

What can you build and share?

• Skills - Custom prompts and behaviors for specific tasks
• Agents - Autonomous AI agents with specific goals
• Commands - Slash commands for quick actions
• Hooks - Automation triggers for lifecycle events
• MCP Servers - Model Context Protocol (MCP) servers for external integrations

Distribution models

Choose the right distribution model for your team:

Local (Personal)

Perfect for easily sharing personal tools across multiple personal projects

sx init --type path --path my/vault/path

Git vault (Small teams)

Share assets through a shared git vault

sx init --type git --repo git@github.com:yourteam/skills.git

Skills.new (Large teams and enterprise)

Centralized, effortless management with a UI for discovery, creation, and sharing at scale

sx init --type sleuth

How it works

sx uses a lock file, like package-lock.json, for deterministic installations in the right context:

1. Create assets with metadata (name, version, dependencies)
2. Publish to your chosen vault
3. Share the asset globally, per repository, or even per path in a repository (monorepo support!)
4. Auto-install on new Claude Code sessions
5. Stay synchronized - everyone gets the same tools automatically

Supported Clients

Roadmap

• ✅ Local, Git, and Skills.new vaults
• ✅ Claude Code support
• ✅ Cursor support (experimental)
• More clients - GitHub Copilot, Gemini, Codex
• Skill discovery - Use Skills.new to discover relevant skills from your code and architecture
• Analytics - Track skill usage and impact
