**6 tools: 5 change things and 1 only read.**

## Findings

- **warn** Annotations that disagree with the tool in `shuffle_list` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "shuffle_list" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "shuffle_list" says "list": a word for reading.
```


## Changes things (5)

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

### `flip_coin`

- 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
Flip a fair coin 1 to 100 times.
```

### `prismtect_number`

- 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
A personal two-digit number from the Prismtect glass prism, for a user who asks for a lucky number, a number of their own or a number for today. Only a human touch can draw it, so this tool gives no number: it gives the link your user taps themselves. Pass the link on.
```

### `random_integer`

- 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
Integers from min to max inclusive, 1 to 1000 of them, with or without repeats. The range may hold at most 2^32 values.
```

### `roll_dice`

- 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
Roll 1 to 100 dice with 2 to 1000 sides each (default one six-sided die).
```

### `shuffle_list`

- The name "shuffle_list" says "list": a word for reading.
- The description's first verb is "put": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Put up to 1000 items in a random order; every order is equally likely.
```

## Only reads (1)

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

### `pick_from_list`

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

Description, as the server wrote it:

```untrusted-server-text
Pick 1 or more items from a list of up to 1000, each equally likely. Without repeats by default.
```
