APM Package Author

APM (docs · GitHub) distributes GitHub Copilot skills, agents, and MCP servers as versioned packages installable with one command. Use this skill to create manifests, wire MCP dependencies, or troubleshoot installs.

When to Use

Use this skill when you need to:

• Create or update an apm.yml root manifest or packages/* sub-manifest for a GitHub Copilot skills/agents repository
• Bundle MCP server configuration into an APM package so consumers get MCP wired automatically on install
• Install a package from a GitHub repo using the APM CLI
• Troubleshoot APM install failures (missing .vscode/mcp.json, Codex CLI warnings, 404 errors, cached installs)

Do not use this skill for:

• General GitHub Copilot customization questions (use default agent)
• Creating SKILL.md files (use the skill-creator skill)
• Writing MCP server implementation code
