The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 12
When the user wants to extract chapters from an EPUB, run the extraction script with uv:
- Very specific: line 18
If output_dir is omitted, creates a folder named after the EPUB in the same directory.
- Distinctive: line 33
After extraction, open the output folder:
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
EPUB Chapter Extractor
Extract each chapter from an EPUB file into its own markdown file.
Instructions
When the user wants to extract chapters from an EPUB, run the extraction script with uv:
cd ~/.claude/skills/epub-chapter-extractor && uv run --with ebooklib --with beautifulsoup4 --with html2text --with lxml python extract_chapters.py "/path/to/book.epub" [output_dir]If output_dir is omitted, creates a folder named after the EPUB in the same directory.
Example
User: "Extract chapters from /Users/yourname/Books/mybook.epub"
cd ~/.claude/skills/epub-chapter-extractor && uv run --with ebooklib --with beautifulsoup4 --with html2text --with lxml python extract_chapters.py "/Users/yourname/Books/mybook.epub"Output files will be at /Users/yourname/Books/mybook/:
01_introduction.md02_chapter_one.md- etc.
After extraction, open the output folder:
open /Users/yourname/Books/mybookOutput Format
Each chapter file contains:
# Chapter Title
[Chapter content in markdown format]Files are numbered for proper sorting: 01_, 02_, etc.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
