v3.0.0

What's New

New Skills

• Visualization Review (reviewing-visualizations) — Critiques existing charts against a prioritized P0/P1/P2 rule system (correctness → perception → polish)
• Dashboard Design (designing-dashboards) — Dashboard layout with KPI hierarchy, component selection, attention choreography, and layout templates

Accessibility by Default

• WCAG AA contrast checks integrated into every skill (4.5:1 text, 3:1 non-text)
• CVD-safe color palettes as defaults (Okabe-Ito, Paul Tol, viridis, cividis)
• Redundant encoding required — never color-only
• Alt text guidance for web/BI output
• New assets/accessible-palettes.md reference

Structural Improvements (Best Practices Alignment)

• Skills renamed to gerund form (visualizing-data, storytelling-with-data, creating-infographics)
• Workflow checklists added to every skill
• Feedback loops in validation steps
• $ARGUMENTS support for dynamic invocation
• Reference files trimmed — removed content Claude already knows
• De-duplicated shared content across skills
• Brand assets moved to shared assets/ directory

Content Enhancements

• Expanded chart selection matrix (dot plots, bullet graphs, slopegraphs, heatmaps, box plots, treemaps, choropleths)
• Context-sensitive data-ink ratio (strict for analytic, flexible for memorability)
• Structured context capture (audience, medium, goal, constraints)
• Integrity constraints (uncertainty annotation, metric definitions, no implied causation)
• Pie chart ban softened to conditional guidance (≤5 slices if user insists)

Breaking Changes

• Skill names changed: visualize → visualizing-data, story → storytelling-with-data, infographic → creating-infographics
• Brand asset paths changed from skills/data-visualization/assets/ to assets/
