The 8 dimensions in this skill were derived from OpenDesign's original 71-system catalog; 71 is the research sample, not the current bundled-system count. Every DESIGN.md in design-systems/ still resolves at minimum: color palette, accent, typography, display font, layout model, and component style. We distilled these into 8 orthogonal dimensions that cover the decisions a designer makes before any pixel is placed. Mood and density were added because they are the two most common sources of ambiguity in natural language briefs ("make it clean" means different things to different people).
Dimensions intentionally excluded from the brief level: animation timing, responsive strategy, and accessibility contrast. These are enforced at the template level by individual skills (e.g., saas-landing handles its own responsive logic), though the generated DESIGN.md includes sensible breakpoint defaults for downstream consumption.
The user provides a design brief in one of two formats:
[PLAN:@DESIGN|type=saas_landing]
|palette=navy_and_white|accent=coral
|typography=inter|display=space_grotesk
|layout=single_column|max_width=1200px
|mood=professional_minimal
|density=spacious|section_gap=96px
|hero=headline+subhead+cta
|sections=features,pricing,testimonials,footer
|exclude=animations,parallax,gradients
|responsive=mobile_first
"I need a landing page for a developer tool. Clean, minimal, dark mode. Inter font. No flashy animations."
If the user provides Option B, convert it to the structured format using the mapping table below, then proceed. Identify every dimension explicitly stated and flag dimensions that were left unspecified.
For each sentence in the natural language input, identify dimension keywords and map to the closest structured value:
| Natural language phrase | Dimension | I-Lang value |
