Four-step diagram showing skills, custom agents, MCP servers, and the usage metrics API.

Summary: GitHub expanded Copilot CLI reporting with agentic activity metrics covering skills, custom agents, MCP servers, slash commands, and plugins.

Why it matters: Agent capabilities become easier to govern when organizations can observe which reusable skills and customizations are actually being used instead of treating the agent layer as an opaque configuration surface.

What to do now

Track reusable agent skills: Use the expanded metrics to see which skills, custom agents, MCP servers, commands, and plugins are actually used.
