Design quality is a system, not a prompt

How DeckForge turns any coding agent into a production-quality presentation builder with 1195 lines of structured workflow.

What prompt templates get wrong

A prompt cannot enforce design discipline

  • No color theory: prompts produce decks with broken contrast, clashing accents, and no harmony scheme
  • No rhythm rules: five identical-weight slides in a row, audience fatigue by slide 6
  • No canvas math: text overflows, font sizes shrink to fit, content disappears under overflow:hidden
Two approaches to deck generation

Prompt template vs structured workflow

Prompt template

  • One-shot generation, no phases
  • Color is "pick something nice"
  • Layout is improvised per slide
  • No contrast or readability checks
  • No self-check before delivery
  • Output quality: luck-dependent

DeckForge workflow

  • 6 phases: brief, structure, outline, HTML, polish, export
  • Color theory: 60-30-10, harmony, contrast, saturation
  • 10 editorial layout types, page rhythm rules
  • WCAG 4.5:1 contrast enforced at generation
  • 8-point self-check checklist before delivery
  • Output quality: system-dependent, repeatable
?

So what does a structured workflow actually look like in practice?

The 6-phase pipeline

Each phase has hard rules and a gate

Phase 0

Brief

Audience, arc, ask, success definition

Phase 1

Structure

Pyramid Principle, assertion headings

Phase 2

Outline

Page type taxonomy, slide types, rhythm

Phase 3

HTML

Canvas scale, viewport fit, budget math

Phase 4

Images

7 named roles, chart anti-patterns

Phase 5-6

Polish + Export

AI tells check, PPTX, PDF delivery

Every slide must have a title that tells the audience what to think, not what the slide is about. If the heading is a topic label, the slide has no point.
