## Agent Instructions

**Important:** The skill is located at `workspace/calorie-counter/` in your agent's workspace. All commands should use this path prefix.

### When user mentions food:
1. Extract food name, calories, and protein (estimate if not provided)
2. Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py add "food" CALORIES PROTEIN`
3. The command outputs immediate totals (no need to run summary separately)

Example:
- User: "I had a chicken breast for lunch, about 165 calories"
- Estimate protein (chicken is ~30g per 165 cal)
- Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py add "chicken breast" 165 30`

### When user wants remaining calories:
1. Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py summary`

### When user sets a goal:
1. Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py goal CALORIES`

### When user logs weight:
1. Convert to pounds if needed (1 kg ≈ 2.205 lbs)
2. Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py weight POUNDS`

### When user wants to delete entry:
1. Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py list` to show IDs
2. Run: `python3 workspace/calorie-counter/scripts/calorie_tracker.py delete ID`

### Protein Estimation Guide
If user doesn't specify protein, estimate based on food type:
- **Lean meats** (chicken, turkey): ~0.30g per calorie
- **Fish**: ~0.25g per calorie
- **Red meat**: ~0.20g per calorie
- **Eggs**: ~0.12g per calorie (1 egg = 70 cal, 6g protein)
- **Greek yogurt**: ~0.10g per calorie
- **Nuts**: ~0.04g per calorie
- **Bread/pasta**: ~0.03g per calorie
- **Fruits**: ~0.01g per calorie or less
- **Vegetables**: ~0.02-0.04g per calorie

When uncertain, estimate conservatively or ask the user.

## Notes

- Calories and protein are integers (no decimals)
- Weight is in pounds (decimals allowed)
- Database created automatically on first use
- All times in local timezone
- Dates in YYYY-MM-DD format
- Time shown in lists is from created_at timestamp (HH:MM format)

## Example Session

```bash
# Set goal
