## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `start_postcard`

- The name "start_postcard" says "start": a word for a change.
- The input addresses people (input.recipient): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Start a Paper Plane Post postcard: a photo printed on a 4×6 card, with an optional illustrated version of it, mailed first class for $7 with postage included. Mails from the US to 194 countries; the address country is an ISO 3166-1 alpha-2 code. Send the photo as photo_base64, encoded from the file itself, or as photo_url if it is already online; add the note and the recipient's address if you know them. Returns a link for the person to open: they see their photo on the card, finish the note and address, can choose the illustrated version, and pay on the website. Nothing is charged or mailed until they do. Never ask for payment details. The link expires after about a week. On a busy day the tool may first answer with a short challenge of four questions to solve and send back in the challenge argument; the proof-of-work question needs a code tool.
```
