Skillful helps you build reusable AI skills and agents as real folders you own. Edit their markdown and supporting files, then install them into multiple AI tools without duplicating source files.
Use collections to keep related work together, preview markdown before editing, repair broken installs, and import shared skill libraries from archives, folders, or GitHub source archives.
First stable release with local skill and agent management, collection import/export, GitHub source archive import, tool installs, markdown preview/editing, frontmatter validation, and cross-platform packaging.
