/plugin marketplace add aiocean/claude-plugins
/plugin install <plugin-name>@aiocean-plugins

Skills load when their description matches your message, hooks fire on tool-call events, agents spawn on the Agent tool. Idle plugins cost nothing — browse plugins or read the guides.

Read-once-and-go walkthroughs. No filler, no marketing — every section answers a question someone actually asks the first time they touch Claude Code plugins.

Pick the guide that matches what you're trying to do. They're independent, so you don't have to read them in order.
