## What it is
APM (Agent Package Manager) is an open-source dependency manager for AI coding agents, letting teams declare skills, prompts, instructions, plugins, and MCP servers in an apm.yml manifest. It resolves transitive dependencies, pins versions with a lockfile, and deploys agent context across harnesses like GitHub Copilot, Claude Code, Cursor, and Codex.

## Use cases
- share agent skills and prompts across a team via a manifest
- reproducibly configure AI coding agents on fresh clones
- install MCP servers into multiple agent clients
- manage agent context dependencies like npm manages packages
- enforce org policy on which agent packages are allowed
- author and version agent plugin packages

## When to choose
- your team uses multiple AI coding agents and needs consistent, portable context
- you want versioned, lockfile-pinned agent dependencies with transitive resolution
- you need governance and security scanning for agent packages in an organization

## When to avoid
- you use a single agent harness with no need for portability
- you only need one-off skill installs without manifest or lockfile management
