## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "steam_convert" says "convert": a word for a change.
```


## Changes things (8)

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

### `steam_bans`

- 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
Steam ban status of a player: VACBanned, NumberOfVACBans, NumberOfGameBans, DaysSinceLastBan, CommunityBanned, EconomyBan - fields exactly as Steam reports them. First thing to check when reviewing a cheating report. Unresolvable ids or an unavailable upstream return an error result, never guessed data.
```

### `steam_batch`

- 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
Up to 100 Steam profiles in one call. When you need several players, ALWAYS use this instead of per-player calls - one batch of 100 costs one request. Accepts any SteamID format as STRINGS - steamid64, STEAM_1:0:x, STEAM_0:0:x, [U:1:x], hex, steam:hex, a 32-bit account id or a /profiles/ link. Never send them as JSON numbers (a 17-digit number loses precision and points at another account) and note that vanity names are not supported here - resolve those with steam_identity first. Players unknown to the platform come back in not_found - fetch those with steam_profile. include can add FACEIT (one query for the batch) and Steam bans (one upstream call for the batch) - the cheapest way to review a full match roster.
```

### `steam_convert`

- The name "steam_convert" says "convert": 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
SteamID converter: turns one identifier into EVERY other form, instantly. Accepts steamid64, STEAM_1:0:x, STEAM_0:0:x, [U:1:x], hex (110000...), steam:hex (FiveM), a 32-bit account id or a steamcommunity.com/profiles/ link. Returns steamid64 (dec and hex), SteamID, legacy STEAM_0 form, SteamID3, account id, steam:hex and the profile URL. CHEAPEST TOOL - prefer it over steam_identity whenever you only need format conversion. Vanity names (steamcommunity.com/id/name) are not a computable format: use steam_identity for those.
```

### `steam_faceit`

- 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
FACEIT player object (nickname, country, per-game skill level and ELO) plus known FACEIT bans. Players without a FACEIT account return an error result saying so - absence of FACEIT data is reported explicitly, never silently.
```

### `steam_friends`

- 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
Known friends of a player from the platform's snapshot of the public Steam friend graph (cache only, no live Steam call; the snapshot can be partial). detail picks token cost: short - steamid64 array, medium - steamid64 + personaname, full - raw Steam objects. Use short unless you need names.
```

### `steam_identity`

- 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
Pure identifier resolver: steamid64, SteamID (STEAM_1:0:x), SteamID3 ([U:1:x]), steam hex, vanity name and profile URL. No profile data - fewest tokens. If the id cannot be resolved, returns an error result with a machine-readable message - never a partial guess.
```

### `steam_profile`

- 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
Steam summary only (raw GetPlayerSummaries object + SteamID conversions). Cheapest profile tool; data no older than 48 hours, unknown profiles are fetched live from Steam. Private profiles return the public subset of fields (not an error); unresolvable ids return an error result.
```

### `steam_summary`

- 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
Steam player overview in one call. presets: include=[] equals full; for competitive checks pass include ["faceit","bans"]. Responses carry provenance.fresh and sources/partial - branch on them. Overview: Steam summary, Steam ban status (VAC/game/community), SteamID conversions, FACEIT stats and the first 100 friends. include LIMITS the response to the blocks you list: omit it for everything, ["steam"] for the Steam block only (cheapest), ["bans"] for a ban check only, ["faceit","bans"] to drop the friend list. friends_limit caps the friend list (default 100).
```

## Only reads (1)

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

### `steam_compare`

- The name "steam_compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Two players side by side: identity, account age, visibility, Steam bans, FACEIT and shared friends (compared over the full friend lists). HEAVIEST tool - it builds two summaries plus both friend graphs; for a single player prefer steam_summary.
```

## Claude Code permissions
