Monday:  Tell Cursor "I prefer dark mode, PostgreSQL, React"
Tuesday: Open Claude Code — it already knows your stack
Friday:  Switch to TRAE — same preferences, zero repetition

1. On your laptop:  carrymem pack -o my_identity.carry --encrypt
2. Copy my_identity.carry to USB drive
3. At new workplace: Install CarryMem on new machine
4. carrymem unpack my_identity.carry
5. Every agent on the new machine knows your preferences, decisions, and rules

1. Create team conventions as rules: "Always use SSL", "Never deploy on Friday"
2. Pack as Skill: carrymem skill-pack rules.json --name team-conventions
3. Share the .json file with team
4. Each member: carrymem skill-install team-conventions.json --scope company
5. All agents now enforce company conventions automatically

Month 1: "I prefer dark mode" → stored as user_preference
Month 3: "Switch to light mode" → auto-supersedes old preference
Month 6: carrymem whoami → shows "I prefer light mode" (dark mode archived)

pip install carrymem && carrymem setup-mcp --all --global

Remember, I prefer PostgreSQL

What database do I prefer?

carrymem pack                    # Creates carrymem_identity_20260526.carry
# Copy to USB / cloud / new machine
carrymem unpack my_identity.carry  # All memories restored

# With encryption for sensitive data
carrymem pack -o my_memories.carry --encrypt   # Password-encrypted .carry file
carrymem unpack my_memories.carry              # Auto-detects encryption, prompts for password

carrymem backup                  # Manual backup (also auto-backup every 20 writes)
carrymem backup --list           # List all backups
carrymem backup --restore memories_backup_20260527_120000.db  # Restore from backup

  Who You Are (according to your AI)
  ==================================================

  Your Preferences:
    ⭐ I prefer dark mode for all editors
    ⭐ I use PostgreSQL for databases
    ⭐ I always use Python for data analysis

  Your Decisions:
    🎯 Let's use React for the frontend

  Your Corrections:
    🔧 The port should be 5432, not 3306
