Hierarchical clustering for nested data grouping

This skill generates comprehensive chapter content for intelligent textbooks after the book-chapter-generator skill has created the chapter structure. Use this skill when a chapter index.md file exists with title, summary, and concept list, and detailed educational content needs to be generated at the appropriate reading level with rich non-text elements including diagrams, infographics, and MicroSims. (project, gitignored)

Helps turn app ideas into shippable MVPs with opinionated guidance on scoping, tech stack (Next.js, Supabase, Vercel), and avoiding feature creep. Use when the user wants to plan an MVP, create a PRD, generate Claude Code prompts, scope features, make product decisions, or needs help staying focused on shipping. Triggers include "plan this app", "help me scope this", "create a PRD", "what should I build first", "generate a Claude Code prompt", or any request to turn an idea into something shippable.

KPI for measuring and improving code quality. Covers lint errors, type safety, test coverage, and verification pass rates. Use to ensure code meets quality standards.
