component-update-layout

component-update-layout is a cursor rule for Cursor from oakensoul/nextjs-cursor-prompts. It costs 0 tokens per session (5,558 once invoked), scanned A, original, MIT.

A set of instructions for improving an existing web layout component across different screen sizes, while preserving compatibility with current uses.

In plain words
What is it for?
Use it to review and update responsive behavior, loading stability, accessibility landmarks, keyboard focus, content slots, and component structure.
Why use it?
It addresses layouts that break on phones, shift while loading, perform poorly, are hard to navigate with assistive technology, or are difficult to reuse.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

component-update-layout scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Layout Component Update Request

Please update and enhance an existing layout component following our responsive design improvement patterns and performance standards:

🎯 LAYOUT COMPONENT UPDATE OBJECTIVES:

  1. ENHANCE responsive design with improved breakpoint handling, container queries, and mobile optimization
  2. IMPROVE performance with optimized rendering, layout stability, and resource efficiency
  3. UPGRADE accessibility with better landmark structure, focus management, and screen reader navigation
  4. OPTIMIZE composition patterns with flexible slots, better content organization, and reusable patterns
  5. MAINTAIN backward compatibility while implementing meaningful layout and architectural improvements

📋 LAYOUT UPDATE METHODOLOGY:

STEP 1: Current Layout Assessment

Analyze Existing Implementation:
  • Responsive behavior: Test layout across all breakpoints and device orientations
  • Performance metrics: Measure Cumulative Layout Shift (CLS) and rendering performance
  • Accessibility audit: Check landmarks, heading hierarchy, and navigation patterns
  • Composition flexibility: Evaluate slot system and content organization capabilities
  • NextJS integration: Review app router compatibility and server component optimization
Identify Enhancement Opportunities:
// Assessment checklist for layout improvements
interface LayoutComponentAudit {
  responsiveDesign: {
    mobileFirst: boolean;
    breakpointConsistency: boolean;
    containerQueries: boolean;
    touchOptimization: boolean;
