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.criticize_toc 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 4d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Goal

  • Review and criticize the table of content for a chapter (or set of chapters) in a book
  • Identify mistakes and improvement opportunities, focusing on factual errors, rather than style suggestions
  • Propose concrete, ranked improvements to topics, ordering, scope, and audience fit

Workflow

Step 1: Read the Material

  • Read .claude/templates/book_map.template.md for the expected structure of a table of content of a book

  • Read the book_map.md that stores the ### Topics making up the table of content for the book

    • Read **Title**, **Target audience** at the top of book_map.md
    • Read the # Part heading description the chapter belongs to
    • Read the target chapter's ### Topics that the user refers to
    • Ignore the rest of the sections besides ### Topics
      • I.e., ### Lessons, ### Tutorials, ### Related packages, ### Related books, ### Related papers
    • Read the ### Topics in the sibling chapters in that Part and the immediate neighbors, chapter N-1 and N+1, to judge continuity

Step 2: Criticize

  • Read .claude/skills/text.criticize/SKILL.md to understand general approaches to review and criticize text

  • Evaluate along these axes, reporting only issues you are confident about:

    • Internal flow:
      • Order of the ### Topics bullets
      • Prerequisite ordering
      • Redundant or overlapping bullets
      • A bullet that is really two topics
    • Cross-chapter flow:
      • Overlap with neighbors or others in the same Part
      • A topic that belongs earlier or later
      • Forward references to concepts not yet introduced
    • Part fit:
      • Does the chapter match the scope description of its # Part (foundations vs. advanced theory vs. deployment)
      • Flag misplaced chapters
    • Structure conformance:
      • Compare the structure to .claude/templates/book_map.template.md
      • Report:
        • Parts that don't follow the subsections
        • Lessons without a FULL/PART/WEAK tag
        • References not following .claude/skills/references.rules.md
    • Audience fit:
      • Matches the stated audience
      • Level too high or low
      • Assumed background
      • Unexplained jargon
    • Scope and balance:
      • Too much or too little content for one chapter
      • Candidates to split or merge

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.
