/slide-authoring

/slide-authoring is the canonical spec for everything inside slides/<id>/. The agent reads it before writing — file contract, the 1920×1080 canvas, type scale, palette, layout vocabulary, the self-review checklist, and the anti-pattern list. /create-slide defers to it for the how.

You don't usually invoke slide-authoring directly. Other skills do.

What it ships

The defaults below are opinionated so an agent doesn't have to reinvent the look of every deck. Override any of it per-deck, or codify your overrides in a theme.

Type scale

A 1920×1080 stage pairs well with bigger type than the web is used to. The scale below is a reasonable default — adjust per deck.

Letter-spacing should tighten as size grows (-0.04em on display, around -0.011em on body).

Palette

A two-tone neutral plus an accent goes a long way. The default dark tokens:

const palette = {
  ink: '#0a0a0c',
  panel: '#111114',
  text: '#f6f5f0',
  textSoft: '#c9c7bd',
  muted: '#7f7e78',
  accent: '#7170ff',
};

Layout patterns

• Hero. One eyebrow, one headline, one supporting line, optional CTA.
• Two-column. 60/40 split. Left for prose, right for visual artefact.
• Index. A list of entries with monospace numbering.
• Quote. Big italic display, attribution in mono.

The agent applies these unless you tell it otherwise.
