## Changes things (3)

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

### `shirt_measurements`

- 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
The real garment measurements of a shirt (chest all the way around and length, in inches) in each size, from the brand's own chart or other checked sources. Not a body-size chart.
```

### `size_me`

- 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
Recommends a size in one shirt for this man, from the shirts he already owns that fit. Returns the size, why (in terms of his own shirts), how it will fit, and a confidence. Tell him exactly the size it gives: it already accounts for his shirts, the fabric and the cut, so don't suggest a different size.
```

### `what_to_buy`

- 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
Builds his Fit Card from the shirts he owns and returns the shirts that will fit him, each in the right size, with a buy link. Also returns a link to his full card on fitcard.ai. Give each shirt in exactly the size listed; a "snugger" or "roomier" note describes how that size fits, not a reason to size up or down.
```

## Claude Code permissions
