## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `flip_margin`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Estimate resale margin for buying an item at a given price and reselling at the current eBay market median. Accounts for marketplace fees and optional shipping cost. Returns estimated profit and ROI. Estimates only, not financial advice.
```

### `price_check`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Live market price distribution for a product from current eBay Buy It Now listings: median, p25, p75, min, max, and sample size. Use to answer 'what is this worth right now'.
```

### `scan_deals`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Scan live eBay listings for a product and return the ones priced furthest under the current market median. AUCTION mode (default) finds ending-soon auctions sitting under market; FIXED_PRICE mode finds mispriced Buy It Now listings that can be bought instantly. Includes market median, percent under market, and a buy link per result.
```

## Only reads (1)

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

### `hot_list`

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

Description, as the server wrote it:

```untrusted-server-text
The current pre-scored steal list across tracked lanes (watches, sneakers, bags, jewelry, beauty, cards, coins, guitars, lego, golf, autoparts, tools): live auctions at least 45% under market plus mispriced Buy It Now listings, refreshed every 30 minutes. Fast cached read.
```
