Additive update to both skill copies. Existing schema/widget reference material is unchanged. New sections: - Workflow — ordered validate → check → query → serve flow, always surfacing http://localhost:8321. - Core Dashboard Rules — start from the analytical question, match chart type to task, the title/chart/footnote 3-widget pattern. - Truthful Visualization Defaults — zero baselines, no pie/3D/dual-y by default, sorted bars, explicit benchmarks, actuals vs forecasts. - Accessibility And Readability — colorblind-safe palettes, never color-alone encoding, readable tooltips, no cramped charts. - Practical DAC Constraints — only use supported schema properties, snake_case output columns, compensate for weak legends in text. - Review Checklist — 10-point pre-signoff list. Refs #7. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Summary
Updates the bundled
create-dashboardskill with additive dashboard-authoring guidance from the reviewed skill comparison, while preserving the newer validation workflow frommain. The existing reference material stays intact; this change layers on practical rules for building clearer, more truthful DAC dashboards.Changes include:
main: no command for UI-only edits,dac validatefor structural checks,dac query --widgetfor per-widget SQL checks, anddac checkonly for final sweeps or broad changes.dac checkas a normal per-edit step.snake_casequery output columns, weak legend support, and keeping semantic logic declarative..claude/skills/create-dashboard/SKILL.mdandcmd/skill_templates/create-dashboard/SKILL.md.Validation

Related to #7.
Conflict resolution: kept both the PR visualization-quality guidance and the validation workflow from
main;dac checkguidance now followsmain.There is still an uncommitted local edit in this workspace changing
.claude/skills/create-dashboard/SKILL.mdfrom port8321to8322; it remains intentionally outside this PR.
