Already have agents and skills?
Import brings them onto the board from .claude or .github in your project, or from your user folder. Skills an agent preloads arrive already linked. Edit them on the board, export, and the same files update in place.
Plugins you installed in Claude Code are linked as they are, by names like superpowers:brainstorming, and never changed.
GitHub and marketplaces: enter a repository like anthropics/skills and pick agents and skills to copy onto the board. Each one remembers where it came from.
