# Budget Tracker

Track every cent your agent spends. Set hard limits. Get alerts before you blow your budget.

## Why This Exists

Autonomous agents with access to APIs, domains, and services can rack up unexpected bills. This skill gives you a financial safety net — log every transaction, enforce spending limits, and always know exactly where you stand.

## Commands

### Log a transaction
```bash
python3 {baseDir}/scripts/budget.py log --amount 10.00 --merchant "Namecheap" --category "domain" --note "arcself.com registration"
```

### Check balance
```bash
python3 {baseDir}/scripts/budget.py balance
```

### View spending summary
```bash
python3 {baseDir}/scripts/budget.py summary
```

### View recent transactions
```bash
python3 {baseDir}/scripts/budget.py history --limit 10
```

### Set budget limit
```bash
python3 {baseDir}/scripts/budget.py set-budget --total 200.00
```

### Set alert threshold (warn when balance drops below this)
```bash
python3 {baseDir}/scripts/budget.py set-alert --threshold 50.00
```

### Check if a purchase is safe
```bash
python3 {baseDir}/scripts/budget.py check --amount 25.00
```

### Export to CSV
```bash
python3 {baseDir}/scripts/budget.py export --format csv
```

## Data Storage

Budget data is stored in `~/.openclaw/budget-tracker/budget.json` by default. Override with `--data-dir /path/to/dir`.

The JSON structure:
```json
{
  "budget": {"total": 200.00, "alert_threshold": 50.00},
  "transactions": [
    {
      "id": "txn_001",
      "timestamp": "2026-02-15T14:00:00Z",
      "amount": 10.00,
      "merchant": "Namecheap",
      "category": "domain",
      "note": "arcself.com"
    }
  ]
}
```

## Categories

Use consistent categories: `domain`, `hosting`, `api`, `tool`, `subscription`, `marketing`, `other`.

## Alerts

When balance drops below the alert threshold, the skill outputs a warning. When a purchase would exceed the remaining budget, it blocks and warns.

## Tips

- Log transactions immediately after spending — don't batch them
- Use `check` before any purchase to verify budget safety
- Run `summary` at the start of each day for awareness
- Set `--alert-threshold` to 25% of your total budget
