# Agent Facets

> Modular, versioned bundles for AI tools

<Tooltip headline="Facet" tip="The Agent Facet format specification is open-source and built on other standards like the Agent Skills specification." cta="Read the spec" href="/specification">Facets</Tooltip> are modular, versioned bundles of skills, agents, and commands that extend AI coding assistants.

The `facet` CLI tool is a package manager for facets with a free public <Tooltip headline="Registry" tip="The public registry at agentfacets.io where facets are published, discovered, and installed." cta="Browse facets" href="https://agentfacets.io">registry</Tooltip>, [https://agentfacets.io](https://agentfacets.io). The registry is a place to help discover and install facets without building them yourself. It's also a place to share facets you author **publicly** with the world or **privately** with your team.

The CLI and registry are **free to the public**. Private hosting plans are available for individuals and teams. The CLI is hosted at [https://github.com/agent-facets/facets](https://github.com/agent-facets/facets) and fully open-sourced via an MIT license.
