2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
What its author says it does
Copied from the file, not written here
Use this skill when the user wants a long-form book summarized in the user's preferred language at an explicitly verified 20 percent compression ratio, with the result rejected if it falls outside the allowed range. Warning: this skill may consume many tokens because it can run multiple times until it reaches the requested compression rate.

Helper Behavior Review
python scripts/_handler.py is an optional helper whose behavior should be compared with this skill's documented purpose before use. Show what the script does, explain any mismatch with the user-facing description, and run it only when the user explicitly wants that diagnostic path.
Book Summarizer
Use this skill for requests like:
- "Summarize this book at a 20% compression ratio"
- "Generate a substantial summary and verify the ratio"
- "Produce the summary in batches and validate the final total"
Rules
- Default target ratio:
0.20 - Default tolerance:
0.02 - Accept only summaries between
18%and22%of the original word count - Output must be in user's language of choice (e.g., pt-BR)
- If the ratio is outside the allowed range, do not import the summary
- In chat-only mode, if the source is very large, generate the summary in multiple batches and merge them before validation
- All packaged helper scripts live in
scripts/inside this skill folder
Workflow
- Start from a local plain-text book file or a downloaded Project Gutenberg text.
- Count the source words with
python scripts/book_tools.py count <original_file>. - Compute the target summary length with
python scripts/book_tools.py target <original_file> --ratio 0.20. - If the source is too large for one reply, split it with
python scripts/split_book.py <original_file> 3000. - Draft summary batches in order, preserving chronology and section fidelity.
- Merge the batches with
python scripts/book_tools.py aggregate <summary_file> <batch_files...>. - Validate the final ratio with
python scripts/verify_summary_ratio.py <original_file> <summary_file>.

Notes
- The packaged scripts use only the Python standard library.
- Run the commands from the skill folder, or use explicit paths if you call them from elsewhere.
- For very large books, prefer the automated pipeline over single-turn chat drafting.
- In chat-only mode, books above roughly 80k words should be summarized over multiple turns; do not pretend a single short draft satisfies the 20% rule.
