Claude Code
Uses the Claude marketplace manifest and /plugin commands. For local development, it can load the Engineering folder with claude --plugin-dir.
Reference
One marketplace. Platform-aware packages.
Sovereign keeps a shared plugin model while allowing each coding agent platform to load the manifest it understands.
Sovereign marketplace

Cursor rules
platform hooks
Marketplace root
Catalogs available packages.
The root repository contains separate .claude-plugin/marketplace.json and .cursor-plugin/marketplace.json catalogs. Both point to Engineering, but resolve its location in platform-appropriate ways.
Plugin package
Defines the bundle itself.
The Engineering directory carries per-platform plugin manifests plus shared agent, skill, and command directories. Cursor rules are Cursor-specific; hooks can differ by platform.
Cursor
Uses the Cursor marketplace manifest through its plugin UI or supported repository flow. It does not use Claude Code’s /plugin commands.
