Meal Planning with Multi-Agent Workflows

We were planning weekly meals the old way: texts, voice memos, and spreadsheets scattered across three apps. Then we built this workflow.

The Challenge

Every week, the same dance:

1. Mom checks the calendar for busy nights (no time for cooking)

2. Dad reviews what's in the fridge

3. Someone searches for recipes

4. Everyone argues about preferences

5. Finally, someone writes a shopping list (and forgets something)

The Solution: Multi-Agent Workflow

Instead of humans passing information around, let models work in sequence:

**Agent 1: Calendar Planner**

**Agent 2: Inventory Manager**

**Agent 3: Meal Generator**

**Agent 4: Shopping List**

**Agent 5: Communication**

How It Works

The workflow:

Calendar Trigger (Weekly, Sunday 6 PM)
        ↓
Read Calendar → (busy nights, events)
        ↓
Read Inventory → (available items, expiring soon)
        ↓
Generate Meals → (respects constraints, time, preferences)
        ↓
Create Shopping List → (consolidated, organized)
        ↓
Send Notification → (family sees plan + shopping list)

The Prompts

**Meal Generator Prompt:**
Plan a week of meals for a family of 4.

Calendar constraints:
{CALENDAR_DATA}

Available ingredients:
{INVENTORY_DATA}

Preferences:
Vegetarian nights: Monday, Thursday
Quick meals: Tuesday, Wednesday (under 30 min)
Celebration dinner: Saturday (guest coming)

For each day, provide:
1. Meal name
2. Time estimate
3. Key ingredients needed
4. 3-sentence description

Format as JSON for easy parsing.

**Shopping List Prompt:**
Create a shopping list from these meals:
{MEAL_PLAN}

Inventory we have:
{CURRENT_INVENTORY}

Rules:
1. Don't include items we already have
2. Group by store section (produce, dairy, meat, etc.)
3. Note quantities
4. Flag any specialty items
5. Estimate total cost

Format as a bulleted list.

Results

After running this workflow for 3 weeks:

**30 minutes saved per week**: No more back-and-forth texts
**Less food waste**: Items expiring soon are prioritized
**Better variety**: The model suggests dishes we wouldn't have thought of
**Happier family**: Everyone sees the plan at once and can object early

How to Build It

1. Connect your calendar (Google Calendar, Outlook)
2. Set up an inventory tracking sheet (manual or RFID scanner)
3. Create the meal planning workflow with the prompts above
4. Test with this week's data
5. Schedule it to run every Sunday

Customizations

**Add Nutritional Goals:**
"Ensure at least 3 servings of vegetables per day"

**Budget Constraints:**
"Keep shopping list under $100"

**Allergy Management:**
Pull allergies from family profiles and filter recipes

**Restaurant Integration:**
On busy nights, suggest local restaurants instead of cooking

**Feedback Loop:**
Every family member rates meals (thumbs up/down) → model learns preferences

The Bigger Picture

This workflow shows what multi-agent systems can do for families:

One person (the model) gathers data
Another person (model) analyzes constraints
A third generates options
A fourth formats the output
A fifth communicates to humans

You're not replacing humans with AI — you're using AI to do the coordination work so humans can focus on what matters (deciding if we like the plan, not managing the logistics).

That's the real power of agentic workflows.
