## Description

Extract TikZ diagrams from Beamer `.tex` source, compile each to a standalone PDF, and convert to SVG with 0-based indexing. Use when user says "extract the tikz", "regenerate the diagrams", "rebuild the SVGs", "sync tikz to quarto", or after editing TikZ blocks in a Beamer deck that also has a Quarto mirror.

# 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`](../new-diagram/SKILL.md), 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`](../../rules/tikz-prevention.md). The pre-check is a small Python script shared with `/new-diagram` so both skills enforce identical behavior:

```bash
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.
