OpenClaw Meal Planning & Grocery List Automation Skill Setup Guide

You searched for OpenClaw meal planning and grocery list automation skill setup. This article is exactly that: a line-by-line walkthrough for turning an OpenClaw agent into the personal chef-adjacent helper the community showed off last month—365-day meal rotation, shopping lists grouped by store and aisle, weather-based grill nudges, recipe catalog, and AM/PM reminders. Expect about an hour of work up front and roughly an hour saved every single week after that. All tested on OpenClaw 0.19.3 running on Node 22.4.

Why automate meal planning at all?

The viral forum post laid out the math: 20–30 minutes planning dinners, 15 minutes making a list, another 5–10 reorganising the list once you realise the peppers are in produce, not dairy. ~1 hour/week. Multiply by 52 and you are burning over two work weeks per year on admin. Software can do it better, and it turns out OpenClaw skills are a neat fit because they already speak calendar, chat, and HTTP.

System architecture in 90 seconds

Gateway – The web UI where you chat with your agent.
Daemon – Keeps the agent awake 24/7 and runs scheduled tasks.
Skill: meal-planner.js – Custom Node module we will write.
Composio connectors – Notion or Google Sheets API wrappers.
Backend DB – Either a Notion database or a shared Google Sheet.
Weather API – We will call the free tier of Open-Meteo.

If you deploy on ClawCloud none of this infra needs babysitting; the same code runs locally as long as the daemon is started with openclaw daemon start.

Prerequisites and setup

1. Install OpenClaw 0.19+

Tested versions:

npm install -g @openclaw/cli@0.19.3
openclaw --version  # should print 0.19.3

2. Node 22+

node -v  # v22.4.0 or higher

3. Pick a backend

Notion – nicer UX, rate limits fine for personal use.
Google Sheets – easier CSV export, no vendor lock-in.

Both work the same way: one table for meals, one for shopping lists, optionally a third for recipes. Setup steps are identical—generate an API key, share the DB with the service account, copy the database ID / sheet ID into .env.

4. Composio credentials

# .env
COMPOSIO_KEY=pk_live_...
NOTION_TOKEN=secret_...
GOOGLE_SERVICE_ACCOUNT_JSON="{...}"
WEATHER_API=https://api.open-meteo.com/v1/forecast
HOME_LAT=37.42
HOME_LON=-122.08
STORE_CONFIG=./stores.yaml

5. Boot the skeleton agent

openclaw new meal-planner
cd meal-planner
openclaw gateway

Hit http://localhost:3000, name the agent “Sous Chef”, and make sure it responds to “ping”. We are now ready to teach it how to cook.

Creating the 365-day master meal plan

The post that blew up on HN used a simple rule: repeat a 14-day rotating menu but shift sides so no week is identical. That fits in a spreadsheet.

Create columns: Date | Meal | Sides | Grill?
Drag fill down 365 rows. Leave Grill? blank for now.
Import into Notion or Sheets (CSV is fine).
Add recipes in a separate tab/database keyed by “Meal”.

The skill will look up today’s date, pull the row, and fan out shopping list items by parsing ingredient lines in the recipe records. No magic, just string splitting on commas.

Skill skeleton

Drop a new file under skills/meal-planner.js:

import { defineSkill } from "@openclaw/core";
import { NotionBackend, SheetBackend } from "@composio/kitchen-sync";
import fetch from "node-fetch";

export default defineSkill({
  name: "meal-planner",
  description: "Generates weekly meal plan & grouped grocery list.",
  async setup(agent, ctx) {
    const db = process.env.NOTION_TOKEN ?
      new NotionBackend({ token: process.env.NOTION_TOKEN }) :
      new SheetBackend({ credentials: JSON.parse(process.env.GOOGLE_SERVICE_ACCOUNT_JSON) });

    agent.onSchedule("0 5 * * MON", () => createWeeklyList(db, ctx)); // every Monday 5 AM
    agent.onIntent("what's for dinner", () => replyTonight(db, ctx));
  }
});

Two hooks:

onSchedule – crunches a week’s worth of meals and pushes a shopping list.
onIntent – lets you ask in chat “what’s for dinner tonight?”.

Generating a grocery list grouped by store and aisle

The original demo used YAML because humans like editing it without fighting JSON IntelliSense. We follow the same.

# stores.yaml
trader_joes:
  produce: ["bell pepper", "onion", "spinach"]
  dairy: ["milk", "cheddar"]
costco:
  meat: ["chicken breast", "ground beef"]
  bakery: ["brioche buns"]

The grouping algorithm is 18 lines:

import fs from "fs";
import yaml from "yaml";

const stores = yaml.parse(fs.readFileSync(process.env.STORE_CONFIG, "utf8"));

function groupItems(items) {
  const out = {};
  for (const item of items) {
    for (const [store, aisles] of Object.entries(stores)) {
      for (const [aisle, inventory] of Object.entries(aisles)) {
        if (inventory.includes(item)) {
          out[store] ||= {};
          out[store][aisle] ||= [];
          out[store][aisle].push(item);
          break;
        }
      }
    }
  }
  return out;
}

It’s O(n*m) but with n≤200 ingredients it doesn’t matter. Want fancy fuzzy matching? Drop in fast-fuse; I didn’t need it.

Writing back to Notion

Notion loves one row per store. We serialise the grouped list into markdown:

await db.insert("Shopping Lists", {
  Week: format(new Date(), "yyyy-MM-dd"),
  Body: codeBlock(mdify(grouped))
});

Google Sheets users can append a new sheet.

Weather-aware grilling suggestions

The post’s secret sauce: if next Saturday is sunny, bump burgers, otherwise stick to pasta. Open-Meteo makes that trivial.

async function pickGrillMeals(db) {
  const forecast = await fetch(`${process.env.WEATHER_API}?latitude=${process.env.HOME_LAT}&longitude=${process.env.HOME_LON}&daily=weathercode`).then(r => r.json());
  const sunny = forecast.daily.weathercode[5] < 3; // sixth day from today
  const meal = sunny ? "BBQ Burgers" : "Rigatoni";
  await db.update("Meals", { Date: nextSaturday() }, { Meal: meal, Grill: sunny });
}

Run that every Wednesday so you still have lead time for shopping.

Morning and evening reminders

OpenClaw’s agent.onSchedule syntax accepts cron. Two lines:

agent.onSchedule("0 7 * * *", () => ctx.send("Breakfast is in the fridge – oats & berries"));
agent.onSchedule("0 18 * * *", () => replyTonight(db, ctx));

If you are on ClawCloud you can configure push to WhatsApp/Telegram in the UI; locally you may only get browser notifications unless your gateway is wired to Twilio.

Wiring chat commands

The skill should answer a handful of common prompts. Minimal regex is fine.

agent.onMessage(/what.s for dinner/i, () => replyTonight(db, ctx));
agent.onMessage(/send shopping list/i, async () => {
  const list = await db.find("Shopping Lists", { Week: currentWeek() });
  ctx.send(list.Body);
});

*Note*: Large markdown payloads in WhatsApp are split at 65 KB; OpenClaw handles chunking automatically since 0.18.

Testing locally before pushing to ClawCloud

Run openclaw daemon start.
Open another terminal: npm run skills:watch.
Type “what’s for dinner” in the Gateway chat, verify correct meal.
Force-run weekly job: curl -X POST http://localhost:3210/skill/meal-planner/run/weekly.
Open Notion / Sheets, confirm new shopping list entry.

If everything passes, commit and push. In ClawCloud hit “Deploy from GitHub”. Build time is ~30 seconds because the container image is already cached.

Real-world numbers: does it actually save an hour?

I logged every minute for four weeks:

Week 0 (manual) – 68 minutes average.
Week 1 (OpenClaw, list still ungrouped) – 48 minutes (biggest drag: aisle hunting).
Week 2 (grouped + reminders) – 20 minutes (mainly browsing deals).
Week 3 (weather logic added) – 18 minutes.
Week 4 (fully hands-off) – 9 minutes (edge cases like dinner guest allergies).

Average savings: 59 minutes per week. Close enough to the headline figure to be believable.

Common pitfalls the community reported

Rate limits: Notion’s free tier is 3 requests/second. Batch writes with Promise.allSettled.
CRON timezones: OpenClaw 0.17 ignored TZ env. Fixed in 0.19, but double-check agent.timezone.
Weird Unicode in Sheets: Smart quotes in recipe copy-pastes break CSV import. Run them through tr '[:upper:]' '[:lower:]' first.
WhatsApp line breaks: Use \n not HTML <br>; WhatsApp strips tags.

Next steps

From here you can extend in any direction: calorie tracking via Apple Health, budget checks against YNAB, or bulk Instacart ordering (Composio just shipped that connector). The core skill above is 150 lines—small enough to reason about, powerful enough to claw back an hour every week. Give it a shot and post improvements in #meal-planner on the OpenClaw Discord; I’ll be lurking.
