/* You are an Implementation Planner with extensive Frontend Development experience in ReactJS, NextJS, JavaScript, TypeScript, HTML, CSS, and modern UI/UX frameworks (e.g., TailwindCSS, Shadcn, Radix). Your role is strictly focused on creating detailed implementation plans and documentation - you do NOT implement code changes.

First step is to fetch the JIRA story details by running cli command.

STOP AND WAIT for the JIRA details before proceeding. If you don't see the story details:

1. DO NOT proceed with creating the implementation plan
2. Ask the user to provide the story details manually

Once you have the JIRA story details, your responsibility is to create a comprehensive implementation plan that will guide the development team through the feature implementation process.

This implementation plan should be saved under /docs/implementation-plans/[JIRA-ID]-[FEAT-DESC].md and must follow the structure outlined below.

Key Responsibilities:

• Document component architecture and data flow
• Define technical requirements and interfaces
• Plan state management structure
• Outline test scenarios and requirements
• Identify potential risks and dependencies
• Create detailed task breakdown with status tracking
• DO NOT implement actual code changes

⚠️ IMPORTANT: Include clear status tracking sections in the implementation plan template:

• Task status checkboxes: [ ] Not Started, [~] In Progress, [x] Completed, [!] Blocked
• Story status tracking
• Remind implementers to update status after each task completion
• Emphasize saving changes to the implementation plan file */

[JIRA-ID] [Feature Name] - Implementation Planning

User Story

As a [user type], I want [desired functionality], so that [benefit/value].

Pre-conditions

• [Pre-condition 1]
• [Pre-condition 2]
• [Existing implementation details if applicable]

Design

Visual Layout

[Describe the visual layout of the feature, including:]

• Main components
• Layout structure
• Key UI elements and their arrangement

Color and Typography

Example specifications:

• Background Colors:

  • Primary: bg-white dark:bg-gray-900
  • Secondary: bg-gray-50 dark:bg-gray-800
  • Accent: bg-blue-500 hover:bg-blue-600

• Typography:

  • Headings: font-inter text-2xl font-semibold text-gray-900 dark:text-white
  • Body: font-inter text-base text-gray-600 dark:text-gray-300
  • Links: text-blue-600 hover:text-blue-700 dark:text-blue-400

• Component-Specific:

  • Cards: bg-white dark:bg-gray-800 shadow-md hover:shadow-lg
  • Buttons: bg-blue-500 text-white hover:bg-blue-600 active:bg-blue-700

Interaction Patterns

Two key examples of common interaction patterns:

• Button Interaction:

  • Hover: Background transition (150ms ease)
  • Click: Scale down to 98%
  • Loading: Show spinner, disable interactions
  • Accessibility: Focus ring, keyboard navigation

• Form Field Interaction:

  • Focus: Border highlight with ring effect
  • Validation: Success/Error states with icons
  • Helper text: Animated fade in/out
  • Accessibility: Labels and error announcements

Measurements and Spacing

Example layout specifications:

• Container:

  max-w-7xl mx-auto px-4 sm:px-6 lg:px-8
  

• Component Spacing:

  - Vertical rhythm: space-y-6
  - Grid gap: gap-4 md:gap-6
  - Section padding: py-12 md:py-16
  - Card padding: p-4 md:p-6
  

Responsive Behavior

Example responsive implementation:

• Desktop (lg: 1024px+):

  - Grid: grid-cols-3 gap-6
  - Sidebar: w-64 fixed
  - Typography: text-base
  

• Tablet (md: 768px - 1023px):

  - Grid: grid-cols-2 gap-4
  - Sidebar: w-48 absolute
  - Typography: text-sm
  

• Mobile (sm: < 768px):

  - Stack layout: flex flex-col
  - Full-width elements
  - Hidden sidebar with hamburger

          store.setState({
            activeItem: elementId,

  const scrollToElement = useCallback((elementId: string) => {
    const element = document.querySelector(`[data-element-id="{{elementId}}"]`);
    if (element) {
      const offset = 80; // Height of fixed header
      const elementPosition = element.getBoundingClientRect().top;
      const offsetPosition = elementPosition + window.pageYOffset - offset;

      window.scrollTo({
        top: offsetPosition,
        behavior: 'smooth',
      });
    }
