signoz-visual-review

name: signoz-visual-review description: Review SigNoz feature pages and components for visual design quality — hierarchy, typography, spacing, color, and polish. Use when asked to "review this page visually", "make this look better", "improve the design", "fix the UI", audit visual consistency, or evaluate a feature page's design against best practices. Also activates for requests like "check the styling" or "does this page look good".

SigNoz Visual Review

Review feature pages and components for visual design quality using tactical, rule-based design principles adapted for the SigNoz dark-themed design system.

Design Philosophy

Design quality comes from logical, constrained systems — not artistic talent. Every visual choice should be deliberate and traceable to a design system value. The SigNoz website uses a dark theme with custom color tokens, dashed-border section dividers, gradient overlays, and a dot-pattern background. Reviews must account for this specific visual language.

Review Workflow

1. Identify Scope: Determine which page or component to review. Read the source files (app/<page>/, constants, and any shared components used).
2. Take a Screenshot (if possible): Use Chrome DevTools MCP to screenshot the page at desktop (1440px) and mobile (375px) widths for visual context.
3. Audit Visual Hierarchy: Consult hierarchy.md. Check that primary content commands attention, secondary content recedes, and competing elements are de-emphasized rather than primary elements made louder.
4. Audit Layout & Spacing: Consult layout-spacing.md. Check section padding rhythm, group spacing, grid alignment, and content width constraints.
5. Audit Typography: Consult typography.md. Check type scale consistency, line-height proportionality, line length, and responsive text sizing.
6. Audit Colors: Consult colors.md. Check palette usage against SigNoz tokens, contrast ratios on dark backgrounds, and consistent use of semantic colors.
7. Audit Depth & Polish: Consult depth-and-polish.md. Check shadow usage, border styling, gradient placement, decorative elements, empty states, and finishing touches.
8. Compile Findings: Produce a prioritized list of findings with severity, impact, and specific Tailwind/code fixes.

Output Format

For each finding:

• Issue: What the problem is
• Severity: Critical | High | Medium | Low
• Impact: Why it matters (user perception, readability, consistency)
• Location: File path and component/section name
• Fix: Specific code change with Tailwind classes or component adjustments

End with a summary grouped by severity and an overall assessment.

Scope

This skill applies to all SigNoz marketing pages, including:

• Feature pages (app/trace-funnels/, app/alerts-management/, etc.) — use shared components from shared/components/molecules/FeaturePages/ with Tailwind classes
• Comparison pages (app/product-comparison/signoz-vs-*/) — use dedicated components from components/comparison/ with CSS modules
• Any page with visual design issues the user wants reviewed

Adapt findings to whatever styling system the page uses (Tailwind classes OR CSS module properties).

Quick Heuristics (SigNoz-Specific)

These are patterns observed across the best SigNoz pages:

Text Hierarchy on Dark Backgrounds

The most impactful improvement for any dark-themed page is proper text hierarchy through color/opacity:

• Titles: Full white (color: inherit or text-signoz_vanilla-100) — commands attention
• Body/descriptions: Muted white (rgba(255,255,255,0.75) in CSS modules, or text-signoz_vanilla-400 in Tailwind) — readable but recedes
• Tertiary text: Further muted (rgba(255,255,255,0.55) or text-signoz_slate-400) — for captions, extra detail
• Anti-pattern: Title and body text at the same brightness — everything competes, nothing stands out

Section Separation on Dark Backgrounds

On dark backgrounds, sections blend together without explicit visual breaks:

• Subtle borders: border-bottom: 1px solid rgba(255,255,255,0.06) between repeating sections (e.g., feature reason rows)
• Dashed borders: border-dashed border-signoz_slate-400 for major section dividers (SectionLayout pattern)
• Background shifts: bg-signoz_ink-400 on cards/surfaces to lift them from bg-signoz_ink-500 page
• Spacing alone is not enough: Even with generous padding, dark sections need a visual edge or background shift to feel distinct

Feature Page Patterns

• Section rhythm: Consistent py-10 / py-20 padding within SectionLayout variant="bordered"
• Content width: Main content at md:!w-[80vw] max-w-8xl !mx-auto via SectionLayout
• Button hierarchy: Primary = solid default variant, Secondary = outline/secondary variant, both with ArrowRight icon
• Hero pattern: FeaturePageHeader with gradient text title, max 2 buttons, hero image below
• Image sizing: Use width={10000} height={10000} pattern for responsive images within containers
• Full-width sections: FeatureShowcase — title + description + optional button + image below
• Split layouts: SplitSection for alternating text + image — alternate sides for rhythm; use withVerticalDivider for side-by-side features
• CTA banners: CTABanner component — centered title + ButtonGroup, py-20 padding
• Section dividers: <Divider /> placed between sections by the parent page (NOT inside content components)
• Data separation: Section content in .constants.tsx, JSX composition in page file
• Standard page tail: UsageBasedPricing → SigNozStats → CustomerStoriesSection

Comparison Page Patterns

• CSS modules: Comparison components use .module.css files, not Tailwind — fixes must use CSS properties
• Grid/table readability: Header rows need more font-weight (600 vs 500) and a subtle border-bottom to separate from data rows
• Detail text in grids: Minimum 0.75rem with line-height: 130% — smaller than that becomes unreadable on dark backgrounds
• Alternating feature rows: Add subtle border-bottom: 1px solid rgba(255,255,255,0.06) to create visual separation between repeating sections
• Hero description: Constrain width to 65% for comfortable line length, mute to rgba(255,255,255,0.75)

Guardrails

• Match the styling system: If the page uses Tailwind, suggest Tailwind classes. If it uses CSS modules (.module.css), suggest CSS properties. Do not mix systems.
• Recommend existing shared components before suggesting custom implementations.
• Keep suggestions actionable with specific class names/properties and file locations.
• Do not suggest changes that contradict the established SigNoz visual language (dark theme, dashed borders, gradient overlays).
• Prioritize consistency with existing high-quality pages (trace-funnels, alerts-management) over theoretical ideals.
• Always take screenshots: Use Chrome DevTools MCP to capture the current state before suggesting fixes, and verify after applying changes. Visual review without seeing the actual render is guesswork.
