Reading Lens
Active-reading scaffolding for nonfiction books (EPUB). Parses an EPUB, generates a structured book analysis in the user's Obsidian vault at Read/{Book Name} ({Author})/, with 0. General.md as the book-level overview and one numbered markdown file per chapter containing pre-read brief, the user's own notes section, and post-read synthesis — all through configurable role lenses (e.g. PM, CEO, Entrepreneur). Six sub-skills — `reading-lens:setup` loads an EPUB with lens selection, `reading-lens:brief` generates a pre-read brief for a chapter, `reading-lens:synthesize` generates a post-read synthesis, `reading-lens:overview-redo` regenerates 0. General.md, `reading-lens:lenses` manages global lens presets, `reading-lens:to-notion` mirrors the book to Notion via MCP. Use whenever the user wants deep, structured book analysis, says "analyze this book", "read this book", "reading lens", "book analysis", "pre-read brief", "chapter synthesis", or references an EPUB path. Prefer this skill for any book-study workflow — even when the user doesn't say its name.

From the source SKILL.md
Active-reading scaffolding for nonfiction books. Given an EPUB, produce a structured set of markdown files in the user's Obsidian vault: book-level overview (0. General.md), per-chapter pre-read briefs (what to watch for), and per-chapter post-read syntheses (what it meant + contrarian takes + actionable experiments). The user takes their own notes in each chapter file — this skill is scaffolding, never a replacement for the user's own thinking.
What this skill does
Reading Lens is a community-contributed Claude Code skill in the knowledge-mgmt sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/reading-lens/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever the user wants deep, structured book analysis, says "analyze this book", "read this book", "reading lens", "book analysis", "pre-read brief", "chapter synthesis", or references an EPUB path. Prefer this skill for any book-study workflow — even when the user doesn't say its name.
