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.
