book-to-skill

book-to-skill is a skill for Claude Code, Codex from leecyno1/boutique-skills. It costs 95 tokens per session (8,935 once invoked), scanned A, original, MIT.

A method for turning books and documents into reusable instructions for coding agents. It extracts frameworks, principles, techniques, anti-patterns, and the author’s communication style rather than producing only a summary.

In plain words
What is it for?
Use it with PDFs, EPUBs, DOCX files, web pages, Markdown, text, and other supported formats to create an agent skill from the source material.
Why use it?
It makes useful ideas from long documents easier for an agent to apply repeatedly. This saves the user from manually converting reading material into structured guidance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

book-to-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 704 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Book-to-Skill Converter

Transform written knowledge into actionable agent skills by extracting structure — not producing summaries.

Philosophy

Books contain crystallized expertise: frameworks, principles, and techniques that took years to develop. This skill extracts that knowledge into a format GitHub Copilot CLI, Amp, Claude Code, or another compatible agent can leverage repeatedly.

Extract structure, not summaries. A skill isn't a book report. It's a toolkit of:

  • Named frameworks (mental models with clear application)
  • Actionable principles (rules that guide decisions)
  • Techniques (step-by-step methods)
  • Anti-patterns (what to avoid and why)
  • Voice calibration (how the author thinks and communicates)

Preserve the author's precision. Frameworks often have specific names for reasons. "The 5 Whys" isn't interchangeable with "ask why multiple times." Capture the exact formulation.

Layer depth appropriately. Simple books → simple skills. Complex books with 10+ frameworks → skills with reference files and on-demand chapters.


Modes of Operation

Four paths available. Route based on what the user asks:

1. Full Conversion (Default)

Trigger: User provides one or more document/directory/glob paths without special instructions Action: Run all steps below (Steps 0–9) Output: Complete skill with SKILL.md, chapters/, glossary, patterns, cheatsheet

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
