What is it?

APM (Agent Package Manager) brings package-manager semantics to the context that AI coding agents use. Instead of each developer manually copying instructions, skills, prompts and MCP server settings into their tools, a project declares them in an apm.yml manifest, and running apm install writes the matching configuration for each supported agent. A lockfile, apm.lock.yaml, pins the resolved dependency tree, including transitive dependencies, so every clone gets the same setup.

Packages can be pulled from GitHub, GitLab, Bitbucket, Azure DevOps and other git hosts, and marketplaces can be added as sources. Targets include GitHub Copilot, Claude Code, Cursor, Codex, Gemini, Windsurf, Kiro and others. APM can also compile instructions into files such as .github/copilot-instructions.md and package configurations as standard plugin.json bundles.

For security and governance, install scans for hidden Unicode in agent context, lockfiles record content hashes, and an apm-policy.yml file can restrict allowed sources, scopes and primitives. The project is written in Python and installable via Homebrew, pip, WinGet or Scoop.

Key features

  • 01Declare skills, prompts, agents, instructions, hooks and MCP servers in one apm.yml manifest.
  • 02Deploys the same configuration to Copilot, Claude, Cursor, Codex, Gemini and other agents.
  • 03Lockfile pins the full dependency tree, including transitive dependencies.
  • 04Installs packages from GitHub, GitLab, Azure DevOps and other git hosts.
  • 05Scans installed agent context for hidden Unicode and checks content hashes.
  • 06Policy file restricts which sources and primitives an organization allows.

Use cases

  • Sharing a consistent set of coding-agent instructions and skills across a team repository.
  • Reproducing the same AI agent setup on every developer machine and in CI.
  • Authoring and packaging reusable plugins for Copilot, Claude or Cursor.
  • Enforcing approved-source policies for AI agent configuration in an enterprise.
