GitHub/CoPilot/CLI/Plugin
- GitHub/CoPilot/CLI's installable bundle. The documented component types are custom agents as
*.agent.md files, skills in subdirectories, hooks in hooks.json, MCP server configuration, and LSP server configuration — see GitHub/CoPilot/CLI/Hook and GitHub/CoPilot/CLI/Subagent. - A
plugin.json sits at the plugin root and a marketplace.json defines a marketplace. Installation from a marketplace, a repository, or a local path is covered in Finding and installing plugins. - That same page adds Anthropic's catalog by repository reference — its worked example is the
claude-code-plugins marketplace hosted at github.com/anthropics/claude-code. See Claude/Code/Plugin/Marketplace. - Copilot also documents
.agents/skills and ~/.agents/skills as valid skill locations, which is the strongest evidence that path is a real interoperability target rather than a spec aspiration. See Agent/Skills/Dir/Compatibility.
