# Skill From Book

Transform book content into structured, context-efficient Claude skills.

## Overview

This skill guides you through converting a book (in markdown format) into a well-organized skill with:
- Granular knowledge files (one concept per file)
- Workflows for repeatable tasks
- Use-case guidelines (mapping tasks to relevant files)
- Progress tracking for multi-session work
- Subagent extraction tasks

## CRITICAL INSTRUCTIONS

**YOU MUST FOLLOW THIS WORKFLOW STRICTLY. DO NOT SKIP OR REORDER PHASES.**

1. **DO NOT read the book markdown file content before starting Phase 1**
2. **MUST read each reference file BEFORE starting its corresponding phase**
3. **MUST complete each phase before moving to the next**
4. **MUST use subagents for extraction tasks**
5. **MUST propose workflows to user before finalization**

## Workflow

### Phase 1: Analysis

**STOP! Before proceeding, you MUST:**
1. Read `references/analysis-guide.md` completely
2. Only then proceed with the steps below

**Phase 1 Steps:**

1. **Extract TOC and outline ONLY** (DO NOT read full book content)
   ```bash
   # Count total lines
   wc -l book.md
   
   # Extract headers/TOC - THIS IS ALL YOU NEED
   grep -E "^#{1,3} " book.md
   ```

2. **Identify knowledge categories from outline**
   - Core principles/philosophy
   - Rules and guidelines
   - Examples (good vs bad)
   - Patterns and anti-patterns
   - Checklists and quick references

3. **Define use cases**
   - Who will use this skill?
   - What tasks will they perform?
   - What questions will they ask?

4. **Ask user to confirm** the identified categories and use cases before proceeding

### Phase 2: Planning

**STOP! Before proceeding, you MUST:**
1. Read `references/extraction-patterns.md` completely
2. Read `references/file-templates.md` completely
3. Only then proceed with the steps below

**Phase 2 Steps:**

1. **Design file structure with required files per category**

   Each category MUST contain these 3 basic fi
