Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install sigma-tutorWith no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.
First time: connect the CLI with
npx --yes palatekit@latest loginThe agent first probes what you know, builds a roadmap of concepts and quizzes you without ever giving the answer. It tracks your misconceptions, sets a practice task before validating each concept and schedules spaced reviews. It produces an HTML roadmap, concept maps and a session summary.

Frequently asked questions
Are extra tools needed?
Not for the essentials. Excalidraw and image generation (the nano-banana-pro skill) are optional for diagrams and visuals.
Where is my progress saved?
In a sigma/ folder in your project: learner profile, session and roadmap per topic.
