## Changes things (3)

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

### `current_tournament`

- 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
Which Grand Slam is in progress right now, how many matches are decided, and how fresh the results are.
```

### `how_4grand_works`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this first. What 4GRAND is, what 'play for love' means, what it costs a player, and how scoring works.
```

### `public_pool_standings`

- 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
The leaderboard of a public community pool, by its share token. Private and club pools are not available.
```
