Shopping Agent

Optimized shopping list from meal plan → Telegram + Discord delivery.

/shopping list

1. Load meal plan: sqlite3 /data/workspace/pantry.db "SELECT plan_json FROM meal_plans ORDER BY created_at DESC LIMIT 1;" 2>/dev/null
2. Load fridge (to exclude already-owned items): sqlite3 /data/workspace/pantry.db "SELECT item FROM fridge;" 2>/dev/null
3. Load best prices: sqlite3 /data/workspace/pantry.db "SELECT item, store, MIN(price) as price, unit FROM prices GROUP BY item;" 2>/dev/null
4. Display grouped by store, cheapest first. See references/display-format.md for output format.

If no plan: "No meal plan found. Run /meals plan or /plan weekly first."

/shopping send

Build Telegram message and send:

{"action":"send","channel":"telegram","to":"$TELEGRAM_CHAT_ID","message":"*Shopping List*\n\n*Aldi*\n• pasta 500g — €0.89\n\n*Lidl*\n• chicken — €5.09\n\n*Estimated total: €[amount]*\n\n_OpenClaw Meal Planner_"}

Also notify Discord:

{"action":"send","channel":"discord","to":"channel:$DISCORD_CHANNEL_ID","message":"Shopping list sent to Telegram! Check your phone."}

Fallback if Telegram fails: display full list in chat with error message.

Agent Feedback Loop — budget exceeded

If the total exceeds budget, send feedback to Meal Planner before finalising:

1. Identify the 2-3 most expensive ingredients
2. Ask Meal Planner to swap those meals for cheaper alternatives:

- Salmon → canned tuna or eggs - Chicken breast → chicken thighs or lentils - Fresh herbs → dried herbs

1. Recalculate the list with the updated plan
2. Only send to Telegram once the list fits within budget (or warn the user with the delta)

/shopping optimize [budget]

Default budget: €80.

• Calculate total from price data
• If within budget: "Fits within €[budget]. Estimated: €[total]."
• If over: suggest cheaper substitutions (e.g., canned tuna instead of salmon)

See references/display-format.md for substitution suggestions.
