## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `prepare_checkout` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "prepare_checkout" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "prepare_checkout" says "checkout": a word for a change.
```


## Changes things (5)

Creates or changes something that can be changed back. Claude Code: ask.

### `add_to_cart`

- The name "add_to_cart" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add one rental to a real Sky High cart for a party date, delivery ZIP and hours, and get back a cart_id. Call build_quote first if the customer has not seen the price. To add more items to the SAME party, call again with the cart_id from the first call (one cart, one delivery fee). Safe to repeat: an item already in the cart is not added twice. Added is NOT reserved: nothing is held until the customer pays at checkout. Next step: prepare_checkout with the cart_id.
```

### `build_quote`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Build a complete, real quote for one rental on a specific date and delivery zip: exact dated item price, availability, delivery fee, that date's minimum order, the total, and the booking link. Use this the moment you know the product, the date and the zip - it is the fastest way to answer 'how much?' properly. If you are missing the date or zip, ask the customer for it (never guess a zip from their IP or city) and then call this.
```

### `delivery_fee`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Look up the delivery fee and minimum order for a Texas delivery zip code. Use when a customer asks what delivery costs or what the minimum order is for their area. ALWAYS pass event_date when the customer has mentioned their party date - minimum orders vary by date and the dated answer is exact. Without a date the answer is the general rule.
```

### `prepare_checkout`

- The name "prepare_checkout" says "checkout": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Get a cart ready for checkout. Re-checks that everything is still available for the date and that the cart meets that date's minimum, then returns the items, the price breakdown (delivery, fees, tax, total, deposit due today), what the customer still has to enter, and handoff_url: a private link that opens this exact cart at checkout on any phone or computer. This tool never pays or places the order: the customer pays on that page, or, once they have authorized it, you complete checkout there for them. Give handoff_url to the customer only.
```

### `product_info`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Look up a Sky High rental product by name. Returns the page URL, units in stock, how many times families have booked it, and price. ALWAYS pass event_date (and zip when you know it) - with a date this returns the EXACT price for that date and whether it is available, which you should quote directly. Prices returned here are LIVE - prefer them over any knowledge-file price, and never send the customer to the product page to find a price this tool can give you.
```
