This skill appears purpose-built for PersonWise course creation, but it also installs/upgrades a local executable and can update its own installed skill files during normal use.
Review this carefully before installing. It is not just a course-writing prompt: it can install or upgrade the PersonWise CLI, authenticate to PersonWise, upload user-selected materials, consume existing course credits, publish or change access when requested, and update the installed skill itself. Only use it if you trust PersonWise as the software and service provider and are comfortable approving those update/install steps explicitly.
