Tell Claude: "generate an image of a modern office building at sunset using the architectural-viz preset"

Tell Claude: "/deck-prompt path/to/report.md --preset consulting"

25 presets organized into 6 categories. Each preset applies a tuned system prompt, default aspect ratio, and resolution so you only need to describe your subject.

5 presets for slide deck generation via /deck-prompt. Each defines a color palette, typography style, style_context, and per-slide-type templates that are automatically applied.

Deck specs use structured fields instead of freeform prompts. The template assembly engine combines these fields with the presentation config's style_context and per-slide-type template to produce the final Gemini prompt.

{
  "slide_number": 3,
  "slide_type": "content",
  "heading": "The Human Impact Equation",
  "visual": "four isometric 3D blocks connected by multiplication signs",
  "labels": ["Direct Effect", "Leverage Effect", "Time Effect"],
  "text_panel": "Employee impact is additive, multiplicative, and exponential.",
  "reference_image": null,
  "style_overrides": {}
}

Slides with a legacy prompt field (no heading/visual) fall back to prefix concatenation for backward compatibility.
