/create-theme

/create-theme codifies a visual recipe into a reusable theme file. Run it once your decks start sharing a visual language — turn the implicit recipe into a file the agent can read.

What it does

Writes themes/<id>.md with the palette, type stack, layout vocabulary, and voice notes that future /create-slide calls can reference.

The input can be:

• An existing deck. The skill scans slides/<id>/index.tsx, distils the recurring tokens, and writes them as markdown.
• A brief. Describe the system in chat ("warm editorial, serif display, high-contrast palette") and the skill bootstraps a theme file from scratch.

Output

A markdown file under themes/:

# 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.

See Themes for how a theme is consumed.

Using the theme

Once the file exists, mention it by name on the next /create-slide:

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

The agent loads themes/corporate.md before writing the deck.
