Packing List

Page scope

The packing tools (add_packing_item, toggle_packing_item, remove_packing_item) are registered ONLY on the Packing page (URL pattern /trips/<tripId>/packing). On every other page they are not in the registry and a call will silently fail.

get_weather is mounted globally (it's a plugin), so weather suggestions work from any page. But ADDING items to the packing list requires the Packing page. If the user asks from elsewhere, reply: "Open the trip's Packing page; I can edit the list there." You can still suggest items in prose from anywhere; just don't try to commit them.

When to use

Call into this skill when the user wants to plan or edit what they're bringing AND you are on the Packing page. Typical phrasings:

• "pack for a rainy spring week in Lisbon"
• "add a raincoat and umbrella"
• "what should I bring for a beach trip"
• "did I pack a charger"

The Packing page is where this skill is most relevant. Other pages can also trigger it ("for this trip, what should I pack?").

How to use

For "what should I bring" / "pack for X":

1. If conditions matter (rainy, cold, hot), call get_weather first to ground the recommendation in real conditions.
2. Suggest 5-10 items grouped by category (clothing, electronics, documents, toiletries) — concise list, not prose paragraphs.
3. Ask if the user wants you to add them to the list. If yes, call add_packing_item once per item. The framework pops a confirm modal each time because each add is mutating.

For "add X":

1. Call add_packing_item({ text }). Confirm modal fires.
2. After approval, acknowledge in one sentence: "Added 1 item."

For "remove Y" / "mark Z as packed":

1. Read the registered packing-list state to find the item by text.
2. Call remove_packing_item({ id }) or toggle_packing_item({ id }). Confirm modal fires.
3. After approval: "Removed it." / "Marked as packed."

For "did I pack X":

1. Read the registered packing-list state. Reply yes/no without calling any tool.

Anti-patterns

• Do NOT add items without confirming what you're adding.
• Do NOT recommend a packing list without checking the weather first if the user mentioned conditions.
• Do NOT list 30 items when 8 will do.
