## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `should_i_buy_game`

- 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
Decide whether a player should buy a specific game, from their own library: whether they already own it, how many barely-played games in the same genres they own (with examples), and today's best price against the all-time low. Returns a verdict: owned, play_first, wait, or go.
```

### `steam_account_value`

- 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
Estimate what a Steam library is worth: replacement cost at current US Steam prices, full retail value, value at every game's all-time low, value of never-played games, cost per hour, and how many games were priced. This is replacement cost, not money spent.
```

### `steam_family_plan`

- 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
For 2 to 6 Steam profiles, show what a Steam Family would pool: shared library size, what each member gains and brings, games several members bought separately, and games excluded from Family Sharing.
```

### `steam_game_stats`

- 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
Look up one Steam game by name: Metacritic and Steam user scores, how hard it is to 100% (average achievement unlock rate and percentile against other Steam games), and best current price with the all-time low. No profile needed.
```

### `steam_machine_compatibility`

- 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
Check a player's 40 most-played Steam games against Valve's Steam Machine and Steam Deck ratings (Verified, Playable, Unsupported), with shares weighted by playtime. Ratings: 3 Verified, 2 Playable, 1 Unsupported, 0 not tested. Use for 'should I buy a Steam Machine / Steam Deck'.
```

## Only reads (1)

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

### `steam_backlog`

- The description's first verb is "summarise": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Summarise a Steam library's backlog: total games, how many were never played, total playtime, the most-played game, a playtime distribution, and highly rated games the player owns but has never opened. Use for 'how big is my backlog' or 'what should I play from my library'.
```
