Add Skills system with XP tracking, auto-leveling, and Notion-style UI

[Copilot]

Implements a persistent RPG Skills system allowing users to track skills and characteristics with XP-based progression. Skills are organized in a two-column layout (characteristics 30% | skills grid 70%) with inline editing, search/filtering, and full CRUD operations.

Database Schema

• skills table: name, description, area, cover_image, xp, level, is_active, related_characteristics[]
• characteristics table: name, icon, xp, level
• Auto-level calculation via triggers: Level = floor(sqrt(XP / 100)) + 1
• RLS policies for user data isolation

-- Level thresholds: L1=0-99, L2=100-399, L3=400-899, L4=900-1599
CREATE FUNCTION calculate_level_from_xp(xp_amount INTEGER) RETURNS INTEGER AS $$
BEGIN
  RETURN FLOOR(SQRT(xp_amount / 100.0)) + 1;
END;
$$ LANGUAGE plpgsql IMMUTABLE;

React Implementation

• useSkills / useCharacteristics hooks with TanStack Query for CRUD + caching
• levelCalculation.ts utility for client-side XP progress display
• 9 UI components in src/components/skills/:
  • Inline creation forms (no modals)
  • Editable characteristic cards with XP input
  • Skill cards with segmented 10-block progress bars
  • Custom confirmation dialogs replacing native alerts

Navigation

Added "Skills" button in Habits page header (next to "+ Create Habit") → routes to /skills

Design System Compliance

• Neutral grayscale palette (removed hardcoded green colors)
• Flat cards, no shadows/glows/gradients
• Monochrome segmented progress bars for skills
• Constants extracted to skillsConstants.ts

Component Structure

// Left column: inline editable characteristics
<CharacteristicCard characteristic={char}>
  - Icon + Name (editable)
  - Level (auto-calculated from XP)
  - Progress bar: xpInLevel / xpNeededForNext
  - Edit/Delete actions
</CharacteristicCard>

// Right column: skill cards with filters
<SkillsGrid>
  - Search input + Active/Inactive/All filters
  - Grid of SkillCard components
  - Cover image, description, area tag
  - Segmented 10-block progress visualization
  - Active/Inactive toggle
</SkillsGrid>

Original prompt

Extend the RPG Gamified Life OS by adding a “Skills” system that is fully functional, editable, and persistent.
This is a core feature, not a static page.

1️⃣ NAVIGATION CHANGE (MANDATORY)

• Add a new button labeled “Skills”
• Place it immediately next to the “+ Create Habit” button
• Button style:
  • Same size and hierarchy as “+ Create Habit”
  • Neutral outline or soft background
  • No accent color
• Clicking Skills opens the Skills system page
  ❌ Do not open a modal
❌ Do not navigate away from Life OS context

2️⃣ SKILLS PAGE – TOP STRUCTURE
Page Title
Skills

• Minimal typography
• Left-aligned
• Neutral gray
  Secondary Controls
• Back button (top-left)
• Optional menu icon (top-right)

3️⃣ PAGE LAYOUT (LOCKED GRID)
Split the page into two main columns:
LEFT COLUMN (≈30%)
Characteristics Panel
RIGHT COLUMN (≈70%)
Skills – Areas Grid
This layout must remain consistent on desktop.

4️⃣ LEFT COLUMN – CHARACTERISTICS (FULLY EDITABLE)
Section Title
Characteristics
Add Controls

• “+ New Characteristic” button
• Inline creation (no modal)
  Characteristic Card Structure
  Each characteristic must include:
• Emoji or icon
• Name (editable)
• Level (auto-calculated)
• XP progress bar
• Numeric XP display (e.g. 285 / 500)
• Star or rank indicator (optional)
  Behavior
• XP updates update level automatically
• Editing XP updates:
  • Level
  • Progress bar
• Persist data

5️⃣ QUICK CREATE PANEL (TOP-LEFT)
Add a Quick Create card with:

• “+ New Area – Skill”
• “+ New Characteristic”
  Purpose:
• Fast creation without leaving the page
• Same Notion-style inline creation

6️⃣ RIGHT COLUMN – SKILLS / AREAS SYSTEM
Section Header
Skills – Areas
Controls

• “+ New Area – Skill” button
• Filter:
  • Active Skills
  • Inactive Skills
• Sort icon (level / XP)
• Search icon

7️⃣ SKILL CARD DESIGN (CRITICAL)
Each skill card must include:

• Cover image (rectangular, subtle)
• Skill name
• Short description
• Current level
• XP progress bar (monochrome blocks)
• Numeric XP (e.g. 440 / 550)
• Star / rank display
  Visual Rules
• Flat card
• Rounded corners
• No shadows
• Notion-style spacing
• Neutral grayscale only
  ❌ No colorful rarity
❌ No glow
❌ No gradients

8️⃣ SKILL FUNCTIONALITY (NON-NEGOTIABLE)
Each skill must support:

• Create
• Edit name / description
• Edit XP
• Auto-level calculation
• Activate / deactivate
• Persistent storage
  Changes must:
• Instantly update UI
• Reflect in Core Metrics / Radar charts if linked

9️⃣ DATA MODEL (REQUIRED)
Structure skills like:
Skill {
id
name
description
area
xp
level
isActive
relatedCharacteristics[]
}
Characteristics:
Characteristic {
id
name
xp
level
}

🔟 STYLE & THEME (STRICT)

• Follow Notion light/dark theme
• No purple
• No fantasy colors
• Use hierarchy, spacing, and typography instead of color
• Skills system must visually integrate with:
  • Profile card
  • Core Metrics
  • Radar charts

🎯 FINAL SYSTEM GOAL
The Skills page must feel like:

• A Notion database
• With RPG mechanics under the hood
• Fully editable
• Fully persistent
• Scalable to hundreds of skills

⚠️ HARD OVERRIDE (ADD THIS LINE)
“Do not generate a static or mock Skills page. This must be a fully functional, editable RPG Skills system.”
