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 B, and why

pdf-extract scanned grade B with 1 finding 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 367 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PDF-to-Markdown Extraction

Convert any PDF document into structured Markdown with extracted diagram/figure images (PNG) and a YAML manifest linking everything together.

Prerequisites

Required CLI tools (check before starting):

pdftoppm -v    # from poppler-utils
convert -version  # from imagemagick

If missing, tell the user to install: sudo apt install poppler-utils imagemagick

The Critical Lesson: Page Mapping First

The single biggest source of errors in PDF extraction is assuming page numbers match content structure. PDFs have cover pages, table-of-contents pages, multi-section pages, and appendices that shift everything.

You MUST build a page map before extracting anything. Read every page of the PDF to understand what content is on each page. This takes a few minutes but prevents hours of debugging wrong extractions.

Workflow

Step 1: Understand the Document

Determine from the user's request or from $ARGUMENTS:

  • Source PDF path: Where the PDF is located
  • Output directory: Where to write the extracted files
  • Scope: The whole document, or specific pages/sections?
  • Document type: Report, article, manual, form, presentation, etc.

If the user hasn't specified an output directory, create one next to the PDF (e.g., document_name/ alongside document_name.pdf).

Step 2: Build the Page Map

Read the PDF page by page using the Read tool (it handles PDFs natively). For large PDFs, read in batches of 15-20 pages.

Read the PDF: pages "1-15"

Verify the actual page count. Don't trust content like slide footers ("1 of 8") or table-of-contents page ranges — these can be wrong. Read the last few pages to confirm where the document actually ends. If pdftoppm fails on a page, the PDF doesn't have that page.

For each page, record:

  • Page number (1-based)
  • What section/chapter it belongs to
  • What content is on it (headings, body text, figures, tables, appendices)
  • Whether it contains images/diagrams that need extraction

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.
