Themes

A theme is a markdown file under themes/<id>.md. The create-slide skill reads a theme before authoring so the agent matches the visual system you want.

Why themes

If you author more than two decks you'll want them to look related. A theme captures the recipe — palette, type stack, layout vocabulary, motion language — in one place that any deck can reference.

File layout

themes/
├── corporate.md
├── editorial.md
└── retro-print.md

Each file is free-form markdown. A useful template:

# Corporate

## Palette
- ink: #0a0a0c
- accent: #4a52b5
- mint: #1f8458

## Typography
- display: 'Söhne', system-ui
- mono: 'JetBrains Mono'

## Voice
- Tight, declarative, never coy.
- One concept per slide.

Using a theme

When you call /create-slide, mention the theme by name:

/create-slide for "Q3 board update — use the corporate theme"

The agent loads themes/corporate.md, applies the palette and type stack, and writes pages that match.

Extracting a theme

Already have a deck whose look you like? Use /create-theme to extract its design tokens into a reusable theme file.
