How It Works
hook runs on PostToolUse and SessionStarttamagotchi-engine- Updates stats based on tool calls and agent events
- Calculates mood from recent event patterns
- Writes to tamagotchi.json
- Statusline-writer reads tamagotchi.json and displays pet
Integration
- achievement-tracker: Shares XP for leveling
- statusline-writer: Displays pet in terminal
- canavar: Error events affect pet mood
- session-compressor: Pet state saved on compact
