book-study

learn-craft builds a working skill from canonical books on any craft or discipline you want to master. It researches the field, fetches PDFs via a bundled downloader, reads them in parallel through subagents, then synthesizes concepts across all sources into a concept-organized knowledge base—not book summaries. Output includes a tight SKILL.md, concept-focused frameworks, and per-book reference deep-dives.

Sigma is a 1-on-1 AI tutor that guides learners through any subject using Bloom's 2-Sigma method—diagnosing understanding, asking targeted questions, and advancing only when mastery is demonstrated. It generates visual learning roadmaps, concept maps, and HTML dashboards to support your progress, while maintaining a learner profile across topics to personalize future sessions.

Transform loose content into a living knowledge base by ingesting articles, documents, or notes into organized wiki pages. The skill automatically extracts concepts, products, and patterns, creates interconnected pages with cross-references, and maintains a searchable index—all while preventing duplicates and keeping your knowledge network coherent.

Literary Ghostwriter helps you write fiction by mimicking the narrative voice and creative approach of seven literary masters—Shakespeare, Zweig, Calvino, Lu Xun, Lao She, Jin Yong, and Gu Long. Beyond single-shot style exercises, it manages full novel projects with world-building, character tracking, plot outlines, foreshadowing management, and multi-role workflows for planning, drafting, and editing.

This skill operationalizes Kolb's experiential learning cycle for live tutoring sessions, replacing explanation with a four-stage loop: learners encounter a phenomenon, notice what surprised them, reconstruct the mechanism through Socratic questioning, and test their claim on a new case. The core discipline is withholding summary and definition until the learner has built the concept themselves—routing the earned claim into an evergreen note before moving to application. Use it to tutor genomics or ML modules, design sessions that enforce desirable difficulty, and decide when to ask rather than answer.

Lesson Study Cycle Designer structures the Japanese jugyō kenkyū process for teacher teams investigating student learning challenges. It generates a research theme, detailed cycle plan with meeting agendas, a research lesson designed for collaborative observation, and protocols focused on case students. The skill grounds itself in evidence from Stigler & Hiebert, Lewis, Perry & Murata, Dudley, and Takahashi & McDougal on how teachers develop shared professional knowledge through structured cycles of planning, teaching, observing, and analysing.
