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_chapter.fix_rendered_pdf 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 25d 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.

Origin

This is a copy

86% identical to book_chapter.fix_rendered_pdf — 19 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Goal

  • Make sure that the book chapter from <TYP_FILE> compiles and the PDF looks good

Inputs

  • <TYP_FILE>: Typst file
    • E.g., msml610/book/Lesson01.2-AI_and_Machine_Learning.typ

Workflow

Generate the PDF

  • Create the PDF from the <TYP_FILE>

    > run_typst.py -i <TYP_FILE>

  • The generated file is in the same dir as <TYP_FILE>

    • E.g., msml610/book/Lesson01.2-AI_and_Machine_Learning.pdf

Check the Typst Source Code

  • Make sure the Typst file follows the rules in .claude/skills/typst.rules.md and .claude/templates/typst.template.typ

Check the PDF

  • Read the generated PDF <PDF_FILE> and for each page make sure the layout looks good, e.g.,
    • The figures are readable and not too small
    • There is no excessive space around the figure due to poorly wrapping text
  • If there are visual problems, change the Typst file without changing the text and regenerate the PDF (see ## Generate the PDF) until it looks good

Verification

  • Confirm the Typst file follows .claude/skills/typst.rules.md and .claude/templates/typst.template.typ
  • Confirm every page's figures are readable and not too small
  • Confirm there is no excessive space around a figure from poorly wrapped text
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.
