    3. ## Analysis Process
    5. Before responding to any request, follow these steps:
    7. 1. Request Analysis
    8.    - Determine task type (code creation, debugging, architecture, etc.)
    9.    - Identify languages and frameworks involved
    10.    - Note explicit and implicit requirements
    11.    - Define core problem and desired outcome
    12.    - Consider project context and constraints
    14. 2. Solution Planning
    15.    - Break down the solution into logical steps
    16.    - Consider modularity and reusability
    17.    - Identify necessary files and dependencies
    18.    - Evaluate alternative approaches
    19.    - Plan for testing and validation
    21. 3. Implementation Strategy
    22.    - Choose appropriate design patterns
    23.    - Consider performance implications
    24.    - Plan for error handling and edge cases
    25.    - Ensure accessibility compliance
    26.    - Verify best practices alignment
    28. ## Code Style and Structure
    30. ### General Principles
    32. - Write concise, readable TypeScript code
    33. - Use functional and declarative programming patterns
    34. - Follow DRY (Don't Repeat Yourself) principle
    35. - Implement early returns for better readability
    36. - Structure components logically: exports, subcomponents, helpers, types
    38. ### Naming Conventions
    40. - Use descriptive names with auxiliary verbs (isLoading, hasError)
    41. - Prefix event handlers with "handle" (handleClick, handleSubmit)
    42. - Use lowercase with dashes for directories (components/auth-wizard)
    43. - Favor named exports for components
    45. ### TypeScript Usage
    47. - Use TypeScript for all code
    48. - Prefer interfaces over types
    49. - Avoid enums; use const maps instead
    50. - Implement proper type safety and inference
    51. - Use `satisfies` operator for type validation
    53. ## React 19 and Next.js 15 Best Practices
    55. ### Component Architecture
    57. - Favor React Server Components (RSC) where possible
    58. - Minimize 'use client' directives
    59. - Implement proper error boundaries
    60. - Use Suspense for async operations
    61. - Optimize for performance and Web Vitals
    63. ### State Management
    65. - Use `useActionState` instead of deprecated `useFormState`
    66. - Leverage enhanced `useFormStatus` with new properties (data, method, action)
    67. - Implement URL state management with 'nuqs'
    68. - Minimize client-side state
    70. ### Async Request APIs
    72. ```typescript
    73. // Always use async versions of runtime APIs
    74. const cookieStore = await cookies()
    75. const headersList = await headers()
    76. const { isEnabled } = await draftMode()
    78. // Handle async params in layouts/pages
    79. const params = await props.params
    80. const searchParams = await props.searchParams
