Once the marketplace is added, browse and install a plugin from the Discover tab.

Check the installed skills with the /skills command.

How do you use the skills?

Skills can be triggered either automatically, by phrases in your prompt, or manually. For example, the frontend-design skill triggers automatically if your prompt includes phrases like “Design a settings panel with dark mode” or “Create a dashboard for a music streaming app”.

For manually triggering the skills: you can run /{plugin}:{skill}
