Quick Start

1. Add a source

Sources are git repositories (or local directories) that contain agents and skills. Register one:

# From a git URL
cmx source add guidelines https://github.com/svetzal/guidelines

# Or from a local directory
cmx source add my-agents ~/Work/my-agents

You can also add Anthropic's official skills:

cmx source add anthropic-skills https://github.com/anthropics/skills

2. Browse available artifacts

cmx source browse guidelines

This shows all agents and skills in the source, with versions and deprecation status.

3. Install artifacts

# Install a single agent
cmx agent install python-craftsperson

# Install from a specific source
cmx agent install guidelines:python-craftsperson

# Install all available agents
cmx agent install --all

# Install into the current project (instead of globally)
cmx agent install python-craftsperson --local

4. Check status

# See everything installed
cmx list

# Check what's outdated
cmx outdated

5. Update

# Update a specific agent
cmx agent update python-craftsperson

# Update all tracked agents
cmx agent update --all
