Skillful

Skillful is a desktop app for building reusable AI skills and agents as folders you own. Edit markdown and supporting files, then install them into tools like Claude Code, Codex, Copilot, Gemini, Cursor, Junie, and opencode without duplicating files.

• Install the same item into multiple tools without copying source files
• Detect and repair broken installs
• Import folders, .skillful.zip archives, and public GitHub source archives
• Open Skillful import links from repositories that publish GitHub-safe import buttons
• Validate frontmatter metadata and warn before incomplete entries drift into your library
• Search and filter large local libraries by collection, tool, and item kind
• Works offline, with the filesystem as the source of truth
