حوّل أي كتاب أو ملف طويل إلى skill في Claude Code بأمر واحدTurn Any Book or Long Document into a Claude Code Skill with One Command

Key terms

Skill

A folder with a SKILL.md file and supporting files. Claude reads the summary first and opens the other files only when it needs them.

Token

The unit a model uses to measure text. A 400 page book is roughly 200K tokens.

book-to-skill

A free, open source (MIT) converter that turns a book or documents into a skill for any host that supports the Agent Skills standard, including Claude Code.

OCR

Turning page images into text. You need it only when a PDF is a scan with no text layer.

The steps

1. 1

   Step 1

   Pick a file you own

   Choose a book you bought, your work documents, or anything you reopen often. It accepts PDF, EPUB, DOCX, Markdown, HTML, RTF and MOBI, plus whole folders or several files at once.

   If your PDF is a scan, there is no text to extract. Run OCR first.

   ocrmypdf.readthedocs.io

   

   PromptOCR a scanned PDF

   Copy

   ocrmypdf [input.pdf] [output.pdf]

   Tip: Only use books you own or documents you have the right to use.

2. 2

   Step 2

   Install book-to-skill

   Open your terminal and run the command below. It installs the converter as a skill and gives you the /book-to-skill command inside Claude Code.

   You can also clone the repo into your skills folder by hand.

   

   PromptInstall

   Copy

   npx skills add virgiliojr94/book-to-skill

   Tip: If the command does not show up, start a new Claude Code session.

3. 3

   Step 3

   Check your extractors

   Each format is read by a different tool. This command lists what is installed and prints the exact command for anything missing.

   For technical books with tables and code, the converter asks you and picks the mode that keeps tables intact.

   

   PromptCheck setup

   Copy

   python3 scripts/extract.py --check

4. 4

   Step 4

   Convert the book

   Inside Claude Code, run the command with the file path. You can add a skill name at the end.

   You convert once. You get SKILL.md with the core ideas and a chapter index, a chapters folder with one file per chapter, glossary.md, patterns.md and cheatsheet.md.

   

   PromptConvert

   Copy

   /book-to-skill [./my-book.pdf] [my-book]

5. 5

   Step 5

   Ask the skill

   Call the skill by name, then your topic or question. Claude reads the summary and opens only the matching chapter.

   By the developer's measurements that is about 5K tokens per question, 24 to 51 times fewer than dumping the whole book into the chat.

   PromptAsk

   Copy

   /[my-book] [topic or question]

   Tip: Ask it which chapters it has to see the index.

6. 6

   Step 6

   Fold in new files

   Got a new paper or an updated document? Run the same command with the path of the existing skill and it merges the new material instead of starting over.

   PromptFold in

   Copy

   /book-to-skill [./new-file.pdf] [~/.claude/skills/my-book]

7. 7

   Step 7

   Keep the skill private

   After converting, the tool offers to publish the skill to GitHub, and it defaults to private. Keep it private for any book that is not yours.

   Your own internal docs and brand guide can be shared with your team within your company's rules.
