Share or open-source any project the user has built — a running preview/service, a project directory, a dashboard, or scripts. Use whenever the user wants to publish, share, make public, list, distribute, deploy publicly, or open-source something.

Do NOT search the filesystem for publish-related code or write custom deploy/upload scripts — this skill is the single entry point.
