Usage Examples in Claude Code

Layer 1: Simple Memory

Remember that the project deadline is next Friday.

Claude will use create_memory automatically.

Layer 2: AI Memory with Evaluation

create_ai_memory({
  content: "Designed a new microservices architecture",
  ai_interpretation: "Shows technical creativity and strategic thinking",
  priority_score: 0.85
})

Layer 3: Personality Analysis

# After accumulating memories, analyze personality
save_user_analysis({
  openness: 0.8,
  conscientiousness: 0.7,
  extraversion: 0.4,
  agreeableness: 0.65,
  neuroticism: 0.3,
  summary: "High creativity and planning ability, introverted personality"
})

# Retrieve analysis
get_user_analysis()

Big Five Personality Traits

• Openness: Creativity, curiosity, openness to new experiences
• Conscientiousness: Organization, planning, reliability
• Extraversion: Social energy, assertiveness, outgoingness
• Agreeableness: Cooperation, empathy, kindness
• Neuroticism: Emotional stability (low = stable, high = sensitive)

Scores range from 0.0 to 1.0, where higher scores indicate stronger trait expression.

Storage Location

All data stored in: ~/.config/syui/ai/gpt/memory.db

Architecture

Multi-layer system design:

• Layer 1 ✅ Complete: Pure memory storage
• Layer 2 ✅ Complete: AI interpretation with priority scoring
• Layer 3 ✅ Complete: Big Five personality analysis
• Layer 4 🔵 Planned: Game systems and companion features
• Layer 5 🔵 Future: Distribution and sharing
