Extract TikZ Diagrams to SVG

Extract TikZ diagrams from the Beamer source, compile to multi-page PDF, and convert each page to SVG for use in Quarto slides.

Creating a brand-new diagram instead of extracting? Use /new-diagram, it scaffolds from templates/tikz-snippets/ with the prevention rules pre-applied.

Steps

Step 0: Freshness Check (MANDATORY)

Before compiling, verify that extract_tikz.tex matches the current Beamer source.

1. Find the Beamer source: ls Slides/$ARGUMENTS*.tex
2. Extract all \begin{tikzpicture} blocks from Beamer
3. Compare with Figures/$ARGUMENTS/extract_tikz.tex
4. If ANY difference exists: update extract_tikz.tex from the Beamer source
5. If extract_tikz.tex doesn't exist: create it from scratch

Step 1: Prevention pre-check (MANDATORY, halt on violation)

Before compiling, verify every \begin{tikzpicture} block in Figures/$ARGUMENTS/extract_tikz.tex satisfies the prevention rules in .claude/rules/tikz-prevention.md. The pre-check is a small Python script shared with /new-diagram so both skills enforce identical behavior:

python3 scripts/check-tikz-prevention.py "Figures/$ARGUMENTS/extract_tikz.tex"

What it checks:

• P3, scale=X without node scaling. Bare scale= shrinks coordinates but not text. Allowed forms: scale=X, every node/.style={scale=X} or scale=X, transform shape. The checker parses the full \begin{tikzpicture}[...] options block even when it spans multiple lines.
• P4, Directional keyword on edge labels. Every edge label (node inside a \draw) must carry above, below, left, right, or a compound (e.g. above left). midway alone is a path position, not a direction. The checker scans the full \draw ...; statement so \draw on one line and node[...]{...} on the next line are still linked.
