What problem does it solve? Malloy renderer annotations fail silently or produce broken output when tags are combined on one line, scales are fixed on measures, or sparklines and dashboards are misconfigured. This Skill catalogs those recurring mistakes so chart annotations, formatting tags, and dashboards render correctly the first time. ## Core Features & Use Cases - Tag Syntax Rules: Enforces one # annotation per line directly above the field, and explains why combined tags fail. - Measure Formatting Guidance: Covers # currency without fixed scale on measure definitions, # big_value cards requiring # label, and comparison deltas with down_is_good. - Sparkline & Dashboard Setup: Details the two-part sparkline requirement (# hidden nested view plus .sparkline= reference) and # dashboard layout rules including columns mode, # colspan, # break, and gap. - Theming Reference: Explains nested palette.* / font.* theme keys, light/dark variants, annotation precedence over instance themes, and which settings are instance-only. - Use Case: Before adding a # bar_chart tile to a Malloy dashboard view, consult this Skill to place each tag on its own line and confirm columns=N is set so # colspan takes effect. ## Quick Start Review the Malloy rendering gotchas before adding chart annotations or building a dashboard in my semantic model.
