Mastery

What is Mastery?

Mastery is an interactive skill tree desktop app to manage, browse, and discover AI agent skills — visualized with classic RPG game UI. Currently supporting Claude Code but soon to support other agents, you can explore your skills, see the token consumption, review the skill.md files, and easily toggle skills without uninstalling. Browse, discover, and install skills directly from the UI. Future versions will let you create and customize multiple skill trees.
