## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_order`

- The name "cancel_order" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel an order that has not been paid yet. Paid orders can be cancelled by emailing support before they are printed.
```

### `pay_order`

- The name "pay_order" says "pay": a word that usually means money moves, which cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Pay for an unpaid order with a Stripe shared payment token (spt_…) the user approved, scoped to at least the order amount in USD. For an order created with recipients, this pays for the whole group at once (scope the token to batch.price). On success the order is paid and goes to print. Use only after the user approved the purchase.
```

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `create_letter`

- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Create a printed letter order (8.5x11, mailed in a #10 envelope) and get a payment link. Either write it (content.body, up to ~3 pages, optional photo) or mail the user's own PDF (content.pdf_url, a public https link, up to 6 pages). Set certified to "certified" for USPS Certified Mail with tracking and proof of delivery, or "certified_return_receipt" to add the recipient's signature; use these when the user needs proof (tax notice replies, lease notices, disputes, demand letters).

```

Front layouts: a big headline on a color, one photo, a photo with a caption, or a collage of 2-4 photos; the back carries the message (handwriting, serif or sans) and addresses. Set express for USPS Priority Mail (2-3 days, tracked). Mails only after the user pays.
