Use plugins / Build plugins
Install available plugins or prepare a portable Agent Plugins 1.0 package.
Use plugins
Available now: install plugins with Universal Agent Plugins. With Node.js 22+, run:
npx universal-agent-plugins add context7For native installation on macOS, Linux or Windows, follow the installer guide. The CLI asks which compatible agents to use; individual plugins may need their own runtimes.
Agent Plugins authoring is available in universal-agent-plugins; GitHub release: agentplugins-v*.
Compatibility is package-specific. Schema validation does not prove runtime, OAuth or activation. Codex does not support declared MCP SSE; stdio and Streamable HTTP keep their existing adapter support.
Client compatibility (English)
Tested client versions and platform limitations
Build plugins
Build a portable Agent Plugins 1.0 package around plugin.json, with optional skills/ and mcp.json. Client support depends on the package and its components.
Agent Plugins authoring is available
Static authoring is available through agentplugins author in universal-agent-plugins; GitHub release: agentplugins-v*. npm, Homebrew, native archives and public-channel E2E are verified. The release does not run package code, start development servers, bootstrap dependencies, export bundles, or publish packages.
