d2-slides

Paths below: <skill> is this skill's directory and <skills> the directory the skills are installed in (skills/ in mizchi/explainer, .claude/skills/ in a project that installed them).

A deck is text: the prose is Markdown, every figure is a ```d2 fence, and the build is a pure function of the file. Nothing is dragged, so a slide can be reviewed in a diff, regenerated after a rename, and — because the output is an HTML page — checked. That last part is the point: a slide deck normally has no failing state, so nobody notices the bullet the frame cut in half.

node <skill>/assets/build-deck.mjs deck.md --out built
# ✓ built/index.html: 8 slides, 5 figure(s) laid out by tala, 26 copy lines → built/copy.txt
#   the deck:   built/index.html   → vlmkit check integrity
#   all slides: built/print.html   → vlmkit check copy --manifest, check a11y contrast, print to PDF
