What it is
APM – Agent Package Manager is an open-source, community-driven dependency manager for AI agents. Think package.json, requirements.txt, or Cargo.toml — but for AI agent configuration.
How it works
APM uses a manifest file called apm.yml to declare agentic dependencies including skills, plugins, agents, hooks, and MCP servers. It provides commands such as apm install to reproduce a configured agent setup across clients, and supports packaging with apm pack and generating Copilot-specific outputs with apm compile -t copilot.
