Copilot Lab plugin

A reference plugin for the GitHub Copilot Up skilling lab.

Important

A plugin folder sitting inside a repository is not discovered or loaded. VS Code and Copilot CLI install plugins from a marketplace or a Git URL into ~/.copilot/installed-plugins/. This copy is here so you can see the anatomy without installing anything.

To actually install a plugin from source:

  • VS Code — run Chat: Install Plugin From Source and give it a Git URL
  • CLI — copilot plugin install PLUGIN-NAME@MARKETPLACE-NAME

Anatomy

PathPortableWhat it contributes
plugin.jsonyesManifest. The $schema value is what marks this as Agent Plugins 1.0
skills/release-notes/SKILL.mdyesA skill, identical in format to a repo-level one
mcp.jsonyesMCP servers that start when the plugin is enabled
com.github.copilot/agents/noCopilot-specific custom agent

Skills and MCP servers are part of the open standard, so any compatible agent picks them up. Agents, hooks and slash commands are client-specific, so they live under a reverse-domain namespace that other clients ignore. That is how one package stays portable while still shipping Copilot-only capabilities.

The point

Everything in this plugin could have been loose files in .github/. Packaging them means a colleague runs one install command instead of copying four folders and hoping they landed in the right place.
