Module plugin 

Plugin system — marketplace-based extensibility for the agent runtime.

A plugin is a directory containing a plugin.json manifest that declares which components it provides: tools, policies, skills, MCP servers, agents, prompt sections, and output styles.

Plugins are installed from marketplaces — curated collections fetched from GitHub, git URLs, npm, pip, or local directories.
