Fridge Manager

Fridge Manager

Track household food inventory via conversation. Auto-calculates expiry from built-in knowledge base, logs all changes, supports cron-based expiry alerts.

Data

Store inventory in family/fridge.json (workspace-relative). Create on first use:

{ "items": [], "log": [] }

Item

{
  "id": "a1b2c3d4",
  "name": "牛奶",
  "category": "dairy",
  "qty": "1 carton",
  "added": "2026-04-27",
  "expiry": "2026-05-04",
  "storage": "fridge",
  "notes": ""
}

Log Entry

Append to log[] on every mutation:

{ "action": "add|consume|discard", "id": "a1b2c3d4", "name": "牛奶", "qty": "1 carton", "reason": "", "ts": "2026-04-27T18:30:00" }

Workflows

Add (入库)

User says they bought/stored food → parse name, quantity, storage location.

1. Look up category + shelf life in knowledge base (read references/food-knowledge-zh.md or references/food-knowledge-en.md matching user language) 2. Calculate expiry = today + shelf life for the matching storage type (fridge → refrigerated life, freezer → frozen life) 3. If item not in knowledge base → estimate conservatively, flag in notes 4. Write to items[], append log[] 5. Confirm: name, location, expiry date. Include one storage tip if notable (e.g., "蚝油必须冷藏")

Batch: "买了牛奶、鸡蛋和西兰花" → add all in one operation, single confirmation message.

Remove (出库)

Three types — detect intent from phrasing:

| Intent | Trigger examples | Action | |--------|-----------------|--------| | Consume | "用完了", "喝了", "used 3 eggs" | Reduce qty or remove if zero | | Discard | "扔了", "threw away", "过期了扔掉" | Remove from items | | Batch cook | "做了番茄炒蛋" | Reduce/remove all ingredients mentioned |

Query

| User says | Response | |-----------|----------| | "冰箱里有什么" / "what's in my fridge" | All items grouped by storage, with expiry status | | "什么快过期" / "what's expiring" | Items within 3 days of expiry, sorted by urgency | | "有鸡蛋吗" / "do I have eggs" | Search by name → qty + expiry | | "冷冻室里有什么" / "what's in the freezer" | Filter by storage location |

Status indicators: 🔴 expired · 🟡 ≤3 days · 🟢 safe

Expiry Alert (cron/heartbeat)

For scheduled invocation. Silent when nothing is urgent.

1. Read family/fridge.json 2. Find items where expiry ≤ today + 3 days 3. If found → send alert:

   🧊 Fridge Alert
   🔴 Expired:
   - 酸奶 (2 days overdue)
   🟡 Expiring soon:
   - 牛奶 (1 day left)
   - 鸡胸肉 (3 days left)
   💡 Tip: consider freezing the chicken if not cooking today
   

#### Cron Setup

Users create a cron via OpenClaw with this task prompt:

Read the fridge-manager skill, then check family/fridge.json for items expiring within 3 days. Send a reminder if any found. Otherwise reply NO_REPLY.

Recommended schedule: daily at 9:00 AM user's local time.

Storage Tips

When asked "how to store X" or during add workflow, consult the knowledge base:

Knowledge Base

Built-in shelf life + storage tips for 60+ common foods, organized by category:

Use fuzzy matching: "chicken breast" → poultry row, "西红柿" → 番茄 row.

Rules

1. Match user's language — Chinese input → Chinese response 2. Conservative expiry estimates when uncertain 3. Confirm every add/remove with a brief summary 4. Keep JSON clean — remove items at zero quantity 5. Log every mutation
