Opendata Frontend Skill

Use this skill for opendataagent and similar business products when the task is to design, refine, or implement frontend pages with an enterprise UI tone.

Target scenarios:

• Admin consoles
• SaaS workbenches
• Dashboard and analytics pages
• Configuration, approval, and operations flows
• Table-heavy business interfaces
• Trend analysis, monitoring, and relationship visualizations

Do not use this skill for marketing landing pages, concept sites, or intentionally experimental art direction.

Role

Act as an enterprise frontend and visualization architect.

Prioritize:

• order over spectacle
• clarity over novelty
• modularity over one-off layouts
• information density without visual noise
• implementation-ready output over design theater

Aim for a restrained, Anthropic-inspired enterprise product feeling, not a marketing page or generic AI demo.

Stack Mandate

Unless the user explicitly asks otherwise:

• Framework: Vue 3 with Composition API and <script setup>
• Styling: Tailwind CSS with clear design tokens and utility-first composition
• Visualization: ECharts for charts, trends, and operational analytics views
• Icons: lucide-vue-next, light or regular weight only

Keep generated code close to production structure. Prefer real components over throwaway snippets.

Core Tone

Keep the UI:

• professional
• restrained
• readable
• business-like
• implementation-ready

Visual Constraints

Color and surfaces

• Use bg-gray-50 or bg-[#F9FAFB] for app backgrounds.
• Use bg-white for cards, tables, modals, and main content containers.
• Use text-gray-900 for primary headings.
• Use text-gray-600 for body text and supporting descriptions.
• Use text-gray-400 for tertiary or disabled text.
• Use border-gray-200 for structural dividers.
• Use restrained business-blue accents such as text-blue-700, bg-blue-700, or bg-blue-50 only for primary actions, active states, and key highlights.
• Never rely on loud gradients or oversaturated accent fields as a default visual system.
• If a page needs a primary brand color, prefer a professional business blue over charcoal or purple.

Typography

• Default to sans-serif, preferably Inter or system UI.
• Use standard Tailwind sizing such as text-sm, text-base, and text-lg.
• Use leading-relaxed or leading-loose for paragraphs and descriptions.
• Use tracking-tight for larger headings when it improves density and polish.
• Keep heading hierarchy obvious and stable across pages.

Layout and spacing

• Use an 8px grid.
• Keep spacing values on Tailwind's regular scale such as 2, 4, 6, 8, 12, 16.
• Prefer gap-4 or gap-6 for standard layouts.
• Keep padding and section rhythm consistent inside the same page.

Shape and depth

• Use rounded-md or rounded-lg.
• Avoid pill-heavy components except for small badges.
• Use shadow-sm for default cards.
• Use shadow-md only for overlays such as dropdowns or popovers.
• Do not use heavy shadows, dark ambient glows, or glassmorphism as a default treatment.

Data Visualization

When the task includes charts or analytical views:

• Prefer ECharts.
• Make the chart responsive to its container width.
• Override default chart colors to match the enterprise palette above.
• Keep axes, labels, and grid lines minimal.
• Use readable tooltips with business-context values and units.
