## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_shop_sales`

- 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
Checks whether a UK shop has a sale on today and when it ends. Returns each sale the shop is running now with its start and end dates and a link, and its sales from the latest December and January with the dates they started and ended. From January Sales' listings of UK shops' sales all year round (Black Friday, Boxing Day, January and the seasons between).
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `list_category_sales`

- The name "list_category_sales" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds which UK shops have a sale on today in one product category, such as electricals, fashion or furniture: one sale per shop, up to five, each with its start and end dates and a link. From January Sales' listings of UK shops' sales all year round.
```
