Layout & typography

How agent-authored slides stay visually coherent.

The slide-authoring skill ships an opinionated baseline so an agent doesn't have to reinvent the look of every deck. You can override any of it.

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.

RoleSize (px)
Display188
H1128
H284
Body28 – 36
Caption / mono14 – 18

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.
