# Salling Food Waste Skill

Find discounted food waste items at Salling Group stores (Netto, føtex, Bilka, Salling, BR) across Denmark via the [Salling Group API](https://developer.sallinggroup.com). Requires a free API key — users must set the `SALLING_API_KEY` environment variable.

## Setup

Get a free API key at [developer.sallinggroup.com](https://developer.sallinggroup.com) and set it as an environment variable:

```bash
export SALLING_API_KEY=your_api_key_here
```

If `SALLING_API_KEY` is not set, the CLI will exit with a clear error message.

## When to use this skill

Invoke this skill when the user wants to:

- Find food waste / madspild deals near a Danish ZIP code or GPS location
- See which stores have discounted items and how many are available
- Browse specific products at a store (prices, discounts, stock)
- Find cheap near-expiry groceries at Netto, føtex, Bilka, or Salling stores
- Compare food waste availability across nearby stores

## Commands

### Search for stores with food waste

```bash
bun run skills/salling-food-waste/cli/src/cli.ts search --zip <zip> [flags]
bun run skills/salling-food-waste/cli/src/cli.ts search --lat <lat> --lon <lon> [--radius <km>] [flags]
```

Key flags:
- `--zip <code>` — Danish ZIP code (e.g. `2200`, `8000`)
- `--lat <n>` and `--lon <n>` — GPS coordinates for geo search
- `--radius <km>` — Search radius in km (default: 5, only for geo search)
- `--format json|table|plain`

Must provide either `--zip` or both `--lat` and `--lon`.

### Get products at a specific store

```bash
bun run skills/salling-food-waste/cli/src/cli.ts products <storeId> [flags]
```

Key flags:
- `<storeId>` — **required** positional arg — the store ID from `search` results
- `--limit <n>` — cap number of products shown
- `--format json|table|plain`

---

## Natural workflow: search → products

1. Use `search` to find nearby stores and get their IDs
2. Use `products <storeId>` to see what discounted items are available at a specific store

```bash
# Step 1: find stores near ZIP 2200
bun run skills/salling-food-waste/cli/src/cli.ts search --zip 2200

# Step 2: get products for a store (use id from results)
bun run skills/salling-food-waste/cli/src/cli.ts products <storeId>
```
