# Town Sandbox CLI — Agent Reference

## New Keynesian Economy System (2026)

The sandbox now uses a **Keynesian economic model** with:

- **Transaction Tax**: 10% on all item purchases/sales
- **Central Bank**: Interest rate policy (1%-20%)
- **Government**: Automatic stabilizer (tax/spending adjustments)
- **Skill System**: Work experience → skill level → higher wages

## Command Format

```bash
town-cli <command> [args...]
town-cli -i                              # interactive REPL

## Economic Strategy Guide

### How to Maximize Income

1. **Work to gain experience**: Each work hour gives 10 XP
2. **Level up**: 100 XP → +0.1 skill level
3. **Higher wages**: Skill 2.0 = 2x base wage

```bash
# Check your current skill
town-cli me
# Look for: skillLevel: 1.0, experience: 150

# Work to gain experience
town-cli work 8   # 8 hours = 80 XP

# Check again - should level up!
town-cli me
# Look for: skillLevel: 1.1, experience: 50
```

### Currency Flow

```
Work → Earn (with skill multiplier)
  ↓
Buy Items → 10% tax to central bank
  ↓
Sell Items → 10% tax deducted
  ↓
Central Bank → Uses tax to stabilize economy
```

### Economic Indicators (Internal)

The system tracks:
- **Inflation rate**: Affects wage adjustment
- **Interest rate**: Controlled by central bank (1%-20%)
