Overview
Extract plain text from EPUB, MOBI, and PDF files using Python scripts. No LLM calls - pure text extraction.
Supported Formats
| Format | Tool Used | Notes |
|---|---|---|
| EPUB | ebooklib + BeautifulSoup |
Direct parsing, preserves structure |
| MOBI | Calibre ebook-convert |
Converts to EPUB first, then extracts |
PyMuPDF (fitz) |
Fast, handles most PDFs well |
Usage
Unified extractor (auto-detects format):
python3 ~/.claude/skills/ebook-extractor/scripts/extract.py /path/to/book.epub
python3 ~/.claude/skills/ebook-extractor/scripts/extract.py /path/to/book.mobi
python3 ~/.claude/skills/ebook-extractor/scripts/extract.py /path/to/book.pdf
Output options:
# To stdout (default)
python3 scripts/extract.py book.epub
# To file
python3 scripts/extract.py book.epub -o output.txt
python3 scripts/extract.py book.epub > output.txt
Format-specific scripts:
python3 scripts/extract_epub.py book.epub
python3 scripts/extract_mobi.py book.mobi
python3 scripts/extract_pdf.py book.pdf
Setup
# One-command setup (installs all dependencies)
~/.claude/skills/ebook-extractor/setup.sh
# Or manually:
pip install -r ~/.claude/skills/ebook-extractor/requirements.txt
brew install calibre # macOS, for MOBI support
Script Location
~/.claude/skills/ebook-extractor/scripts/
Common Issues
| Problem | Solution |
|---|---|
| Missing package | Run setup.sh or pip install -r requirements.txt |
| MOBI fails | Ensure Calibre is installed: brew install calibre |
| PDF garbled | Some PDFs are image-based; OCR needed (not supported) |

brave-search
Use when user asks to search the web, look something up online, find current/recent/latest information, or needs cited answers. Triggers on "search", "look up", "find out about", "what is the current/latest", image searches, news lookups. NOT for searching code/files—only for web/internet searches.

bug-reproduction-validator
Use this agent when you receive a bug report or issue description and need to verify whether the reported behavior is actually a bug. This agent will attempt to reproduce the issue systematically, validate the steps to reproduce, and confirm whether the behavior deviates from expected functionality. <example>\nContext: The user has reported a potential bug in the application.\nuser: "Users are reporting that the email processing fails when there are special characters in the subject line"\nassistant: "I'll use the bug-reproduction-validator agent to verify if this is an actual bug by attempting to reproduce it"\n<commentary>\nSince there's a bug report about email processing with special characters, use the bug-reproduction-validator agent to systematically reproduce and validate the issue.\n</commentary>\n</example>\n<example>\nContext: An issue has been raised about unexpected behavior.\nuser: "There's a report that the brief summary isn't including all emails from today"\nassistant: "Let me launch the b...

brainstorming
This skill should be used before implementing features, building components, or making changes. It guides exploring user intent, approaches, and design decisions before planning. Triggers on "let's brainstorm", "help me think through", "what should we build", "explore approaches", ambiguous feature requests, or when the user's request has multiple valid interpretations that need clarification.

performance-oracle
Use this agent when you need to analyze code for performance issues, optimize algorithms, identify bottlenecks, or ensure scalability. This includes reviewing database queries, memory usage, caching strategies, and overall system performance. The agent should be invoked after implementing features or when performance concerns arise.\n\n<example>\nContext: The user has just implemented a new feature that processes user data.\nuser: "I've implemented the user analytics feature. Can you check if it will scale?"\nassistant: "I'll use the performance-oracle agent to analyze the scalability and performance characteristics of your implementation."\n<commentary>\nSince the user is concerned about scalability, use the Task tool to launch the performance-oracle agent to analyze the code for performance issues.\n</commentary>\n</example>\n\n<example>\nContext: The user is experiencing slow API responses.\nuser: "The API endpoint for fetching reports is taking over 2 seconds to respond"\nassistant: "Let me invoke the...
