law-pagecount

law-pagecount is a skill for Claude Code, Codex from li-ch/law-skills. It costs 44 tokens per session (362 once invoked), scanned A, original, MIT.

A page-counting tool for a compiled LaTeX paper PDF. It reads the PDF's bookmarks, which are its clickable section headings, to report how many pages each paper section occupies.

In plain words
What is it for?
Use it after building a paper to count pages by section, enable missing bookmarks when needed, and record reminders to disable them before submission.
Why use it?
It gives section-level page usage after a successful build instead of requiring manual counting.

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

law-pagecount 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 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/count-pages.sh, scripts/enable-bookmarks.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

LAW Page Count

Count pages per section from a compiled paper PDF. This is invoked automatically after law-build succeeds.

Workflow

Step 1: Check for bookmarks

If the PDF has no bookmarks (outlines), enable them by running scripts/enable-bookmarks.sh, then trigger a rebuild before counting.

Step 2: Count pages

Run scripts/count-pages.sh [paper_root] which uses pikepdf (or pdftk fallback) to extract section titles and page numbers from the PDF outline.

Step 3: Report

Output the per-section page counts in a readable format:

§1 Introduction — pages 1–2 (1.5 pages)
§2 Background — pages 3–4 (1.2 pages)

Step 4: Leave reminders

After counting, add a note to todo.md:

- [ ] Re-disable PDF bookmarks before submission (enabled by law-pagecount)

And add a note to AGENTS.md if not already present:

<!-- law-pagecount: bookmarks re-enabled for page counting. Re-disable before submission. -->

Step 5: Re-disabling bookmarks

Only re-disable bookmarks when the user explicitly asks. The user must request it — never do it automatically.

Prerequisites

  • Python 3 with pikepdf (pip install pikepdf) OR pdftk

If neither is installed, report the missing dependency and skip the count.

Files

What ships with it

2 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.
