Felipe Cardoso 96df7edf88 Refactor useAuth hook, settings components, and docs for formatting and readability improvements 
- Consolidated multi-line arguments into single lines where appropriate in `useAuth`.
- Improved spacing and readability in data processing across components (`ProfileSettingsForm`, `PasswordChangeForm`, `SessionCard`).
- Applied consistent table and markdown formatting in design system docs (e.g., `README.md`, `08-ai-guidelines.md`, `00-quick-start.md`).
- Updated code snippets to ensure adherence to Prettier rules and streamlined JSX structures.

Design System Documentation - Project Progress

Project Goal: Create comprehensive, state-of-the-art design system documentation with interactive demos

Start Date: November 2, 2025 Status: Phase 1 Complete ✅ | Phase 2 Pending

Project Overview

Vision

Create a world-class design system documentation that:

  • Reusable utility components in /src/components/dev/
  • Consistent styling and navigation
  • Deep linking support with section IDs
  • Back navigation to hub from all pages

Key Decisions Made

  1. Documentation Structure

    • Decided to create subfolder docs/design-system/ instead of root-level files
    • Numbered files for clear progression (00-99)
    • Separate AI guidelines document (08-ai-guidelines.md)
    • Quick reference as 99-reference.md (bookmark destination)

  2. Learning Paths

    • Created 6 different learning paths for different user needs
    • Speedrun (5 min) → Comprehensive Mastery (1 hour)
    • Specialized paths for component development, layouts, forms, AI setup

  3. Content Philosophy

    • Pareto principle: 80% coverage with 20% content
    • 5 essential layouts cover 80% of needs
    • Decision trees for common questions
    • Before/after examples showing anti-patterns

  4. AI Optimization

    • Dedicated 08-ai-guidelines.md with strict rules
    • ALWAYS/NEVER sections for clarity
    • Component templates for AI code generation
    • Integration instructions for Claude Code, Cursor, GitHub Copilot

  5. Link Strategy

    • Internal doc links: Relative paths (./02-components.md)
    • Demo page links: Absolute routes (/dev/components)
    • Anchor links for specific sections (#color-system-oklch)
    • All links verified during review

Next Steps

Immediate: Begin Phase 2

  1. Create utility components (BeforeAfter.tsx, CodeSnippet.tsx, Example.tsx)

    • Reusable across all demo pages
    • Consistent styling
    • Copy-paste functionality

  2. Enhance /dev/page.tsx (hub)

    • Landing page for all demos
    • Quick navigation

  3. Create demo pages in order

    • /dev/components/page.tsx (most referenced)
    • /dev/layouts/page.tsx
    • /dev/spacing/page.tsx
    • /dev/forms/page.tsx

Future Enhancements (Post-Phase 2)

  • Add search functionality to documentation
  • Create video tutorials referencing docs
  • Add print-friendly CSS for documentation
  • Create PDF versions of key guides
  • Add contribution guidelines for design system updates

Lessons Learned

  1. Ultrathink Required

    • Initial plan needed refinement after user feedback
    • Comprehensive review caught issues early

  2. Time Estimates Removed

    • User preference: No time estimates in section headers
    • Focus on content quality over reading speed

  3. Link Verification Critical

    • Agent review caught broken cross-references
    • Incomplete imports in examples
    • Fixed before Phase 2 begins

  4. Documentation Coherence

    • Cross-referencing between docs creates cohesive system
    • Multiple entry points (learning paths) serve different needs
    • Quick reference (99-reference.md) serves as bookmark destination
