Agent Plugins 1.0 is an open, vendor-neutral specification for packaging Agent Skills and MCP server configurations into a single reusable plugin. Package your capabilities once, then bring them into VS Code, GitHub Copilot CLI, the GitHub Copilot app, and other clients that support the standard.
The idea is simple: Build once. Use everywhere.
Agent plugins are prepackaged bundles of agent customizations that you can discover and install from plugin marketplaces in Visual Studio Code. Plugins work alongside your locally defined customizations. When you install a plugin, its supported customizations become available in the relevant agent interfaces.
Agent Plugins is an open standard for packaging agent skills and MCP servers that works across multiple AI agents, including GitHub Copilot in VS Code, GitHub Copilot CLI, and the GitHub Copilot app. VS Code also supports client-specific plugin capabilities, including slash commands, custom agents, rules, hooks, and automation templates. In an Agent Plugins package, most of these capabilities come from the com.github.copilot namespace. The existing Copilot and Claude plugin formats keep their own layouts.
