Gousto Meal Picker

Gousto Meal Picker

Automates weekly Gousto recipe selection via their REST API. No browser needed for picking — only for initial auth and token refresh.

Setup

1. First-time auth (browser required)

Use agent-browser to log into Gousto and save session state:

agent-browser open "https://www.gousto.co.uk/my-gousto" --headed
# User logs in manually (CAPTCHA blocks automated login)
agent-browser state save <workspace>/gousto/gousto-auth.json
agent-browser close

2. Create config

Create <workspace>/gousto/config.json:

{
  "userId": "<auth_user_id from /user/current>",
  "numericUserId": "<numeric id>",
  "deviceId": "<from gousto_session_id cookie>",
  "subscriptionId": "<from subscription endpoint>",
  "shippingAddressId": "<from order>",
  "deliveryTariffId": "<from order>",
  "plan": {
    "mealsPerWeek": 4,
    "portions": 2
  },
  "rules": {
    "maxCookTimeMins": 45,
    "maxMealsOver40Mins": 1,
    "noNuts": true,
    "noFish": true,
    "maxPastaPerWeek": 1,
    "maxRicePerWeek": 1,
    "preferHealthy": true
  }
}

No passwords or credentials are stored in config.json. Auth is handled entirely via browser cookies saved in gousto-auth.json (from the login step above). The config only contains Gousto account IDs and selection rules.

To discover IDs: log in via browser, then call GET /user/current and inspect a pending order via GET /order/v2/orders/<id>. See references/api.md for endpoint details.

3. Initialise selections tracker

Create <workspace>/gousto/selections.json:

{ "selections": {} }

Usage

Run the picker

node <skill-dir>/scripts/gousto-pick.mjs [--dry-run] [--week ORDER_ID]

• --dry-run — show what would be selected without updating the order
• --week ORDER_ID — target a specific order instead of auto-detecting

Recommended cron schedule

Gousto menus open on Tuesdays at 12pm UK, 13 days before Monday delivery. Schedule the picker for Tuesdays at 1pm UK:

cron: "0 13 * * 2" (Europe/London)

Token refresh

Auth tokens expire ~10 hours after login. When the token expires, the agent should:

1. Open Gousto in agent-browser (loads saved state → auto-refreshes)
2. Save updated state: agent-browser state save <workspace>/gousto/gousto-auth.json
3. Retry the script

Auth endpoints are WAF-protected — curl cannot hit /oauth/access-token or /login directly. Browser-based refresh is the only reliable method.

Selection Rules (all configurable)

All rules are set in config.json under "rules". Every filter can be toggled on/off.

Hard filters (set to true to exclude)

Soft constraints (limits per week)

Scoring preferences

Example config

{
  "rules": {
    "noNuts": true,
    "noFish": false,
    "noVegetarian": false,
    "maxCookTimeMins": 30,
    "maxPastaPerWeek": 2,
    "excludeKeywords": ["spicy", "chilli"],
    "excludeAllergens": ["sesame"],
    "preferHealthy": false
  }
}

Security notes

• No passwords stored — auth uses browser cookies only (saved in gousto-auth.json)
• Treat gousto-auth.json as sensitive — it contains OAuth tokens. Restrict file permissions (chmod 600)
• Single API endpoint — the script only communicates with production-api.gousto.co.uk
• Use --dry-run first — verify selections before enabling automated ordering
• Required runtime — Node.js, curl, zsh shell, and agent-browser (for login/token refresh only)
