restructure

This skill should be used when the user asks to "restructure CLAUDE.md", "restructure AGENTS.md", "create a documentation index", "add a table of contents to CLAUDE.md", "organize project docs", "refactor root configuration file", "build a doc index", or wants to restructure how a repository's root configuration file references its documentation. Generates a thematic, book-style index in the highest-precedence root configuration file.
